## concrete 1 stone mass to cubic meters converter

This general purpose concrete formulation, called also concrete-aggregate (4:1 - sand/gravel aggregate : cement - mixing ratio w/ water) conversion tool is based on the concrete mass density of 2400 kg/m3 - 150 lbs/ft3 after curing (rounded). Unit mass per cubic centimeter, concrete has density 2.41g/cm3. The main concrete calculator page.

The 4:1 strength concrete mixing formula applies the measuring portions in volume sense (e.g. 4 buckets of concrete aggregate, which consists of gravel and sand, with 1 bucket of cement.) In order not to end up with a too wet concrete, add water gradually as the mixing progresses. If mixing concrete manually by hand; mix dry matter portions first and only then add water. This concrete type is commonly reinforced with metal rebars or mesh.

With the above mentioned two-units calculating service it provides, this concrete converter proved to be useful also as an online tool for: 1. practicing stones and cubic meters of concrete ( st vs. m3 ) measuring values exchange. 2. concrete amounts conversion factors - between numerous unit pairs. 3. working with - how heavy is concrete - values and properties.

How many cubic meters of concrete are in 1 stone? The answer is: The change of 1 st ( stone ) unit of concrete measure equals = to 0.0026 m3 ( cubic meter ) as the equivalent measure for the same concrete type.

In principle with any measuring task, switched on professional people always ensure, and their success depends on, they get the most precise conversion results everywhere and every-time. Not only whenever possible, it's always so. Often having only a good idea ( or more ideas ) might not be perfect nor good enough solution. If there is an exact known measure in st - stones for concrete amount, the rule is that the stone number gets converted into m3 - cubic meters or any other concrete unit absolutely exactly.

To link to this concrete stone to cubic meters online converter simply cut and paste the following. The link to this tool will appear as: concrete from stone (st) to cubic meters (m3) conversion.

## how to wire a washing machine motor as generator : 3 steps (with pictures) - instructables

A generator is a device that converts motive power into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines and even hand cranks. The first electromagnetic generator, the Faraday disk, was built in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids.The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity and frequently make acceptable manual generators.

A Generator can be any motor in reverse.Washing machine motor generator wiring is a how to wire washing machine motor into a generator.There are many types of ac/dc motors out there like induction motors, universal motors, synchronous motors and many more.Washing machine motor generator https://www.youtube.com/watch?v=_jKTsAJK8aQ Washing machine motor wiring basics https://www.youtube.com/watch?v=XlaHSZFGzp0 Washing machine motor speed control https://www.youtube.com/watch?v=lRj6V7ygBQo Incredible washing machine motor on battery https://www.youtube.com/watch?v=TcMUTqSvOsw Today video is all about how to connect the washing machine motor into a generator wich is very simple you just have to apply power to the field windings and you have to rotate the shaft, rotor, or brushes to generate electricity.

kind of current more limit the simplest current more limit you can use a 12v incandescent lamp, like the one used in car light start from 5w-20w and that will limit the current going to the field windings.

The universal motor is so named because it is a type of electric motor that can operate on AC or DC power. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator.It is often referred to as an AC series motor. The universal motor is very similar to a DC series motor in construction but is modified slightly to allow the motor to operate properly on AC power.

## dupe creates "biological concrete" from sand, bacteria and urine

With energy production and raw material shortages becoming increasingly pertinent issues around the world, designer Peter Trimble has demonstrated a radical method of manufacture that addresses both issues. Dupe is a portable machine that uses a mixture of sand, bacteria and urine to create a material called biostone. The machine is a proof-of-concept design only and is currently set up to create a small stool, but the method can be adapted to create just about anything.

Trimble's work was part of an open brief while studying at the Edinburgh College of Art. He decided to look at the sustainability of material production and found that cement production was the most environmentally damaging. Not only is the biostone he subsequently produced environmentally-friendly, but it could be easily made as bricks for building housing in developing countries or remote places.

"Currently, materials use 'heat, beat and treat' methods of production, carving things down from the top with 96 percent waste and only 4 percent product," says Trimble. "The 96 percent can be accounted for through the mining of raw materials, the burning of fossil fuels in manufacture and transportation at each stage of the products life."

The procedure for creating biostone involves filling a mold of the final required shape with sand before pumping a bacteria solution of bascillus pasterurii (which has been grown in a nutrient broth) into the mold and leaving the mixture to establish itself overnight. A solution of calcium chloride, urea and nutrient broth is then pumped into the mold. The bacteria uses the urea as energy to absorb the calcium chloride and convert it into calcium carbonate, a cement-like mixture that binds the sand together within the mold.

"The development process was difficult, particularly getting the recipe for the chemicals correct," explains Trimble to Gizmag. "I had lots of problems with PH levels. At the beginning the solution would kill the bacteria or cause the calcite to precipitate too quickly. I found that pumping the solution upwards (against gravity) through the sand produced more consistent results as it avoided preferential flow. Other problems where fundamental things like the molds leaking."

According to Trimble, the method of "microbial manufacture" used by Dupe explores the possibility of replacing energy-intensive methods of production with more efficient, biological processes. Though not aiming to provide any definitive answers, he hopes the project will encourage discussion about how industrial manufacturing can be made more sustainable.

"The process forms mineral composites at biological temperatures," says Trimble. "The biomaterial is structurally comparable to concrete, yet the production of the biomaterial produces no greenhouse gases. Concrete is responsible for 5 percent of the world's man-made CO2 emissions. The biomaterial produced by this process is a stepping stone in the right direction for the reduction of these carbon emissions."

Dupe is by no means the first time urine has been used for good. French design group Faltazi created L'Uritonnoir, a composting urinal that helps to turn a hay bales into fertilizer, and scientists at Bristol Robotics Laboratory created a urine-powered fuel-cell for mobile phones.

## 7 best pressure washer sandblasting kits (reviews & guide 2020)

Pair your power washer with the best pressure washer sandblasting kit will help you remove rust and paint, it can even help you remove those extremely difficult stains on your driveway. These kits will transform you pressure washer into a sandblasting machine, adding a whole new element to an already impressive tool.

In a hurry? I personally use the Tool Daily 5000 PSI Pressure Washer Sand blasting Kit, its not the most expensive on the list but does everything I need and can handle a massive amount of PSI, should I need a lot of force to do the job.

Wet sandblasting has become popular for many reasons, and ill show you everything you need to know to get started the right way. Ive put together a buying guide and ive also prepared some pressure washer sandblasting kit reviews of my favorite models.

The only thing you need asides this is a pressure washer, which is considerably cheaper (and in my opinion far more useful to have around the house) than the alternative option which is an air compressor. If you dont own a pressure washer already, then I highly recommend looking at either my electric pressure washer guide or if you want some serious power my gas pressure washer guide.

These sandblasters produce a lot of dust, which is incredibly dangerous to inhale. If you use a dry sandblaster, you need to make sure that nobody comes near without a mask, which is rather tricky to do if you are working from home.

Unlike the dry sandblasters, water-based sandblasting is mostly dust-free, thats not to say you shouldnt wear a respirator mask, but as the particles of sand fall down with the water droplets. Its a safe option if you want to work on a project in your own backyard. Wet sandblasting is safe and eco-friendly.

Dealing with plastic or thin metal can be tricky, as these surfaces tend to be heat sensitive. Using a dry sandblaster, these surfaces can get damaged by heat. Whether thats warping, bending, or discoloration.

Fortunately, with a wet sandblaster, as you blast the surface with the sand and water mix from your pressure washer, the water cools the surface keeping the temperature under control. When you wet sandblast, the surface will never overheat.

This sandblasting kit is made with relatively cheap materials, but dont let that put you off. This a cracking bit of equipment if you are only going to use it infrequently i.e. preparing a fence for new paint.

Attached to the rubber hose is a 10-inch sand wand, this is the part of the kit that you stick into your sand bucket. The sand wand has a perfect design so that it produces optimal sand suction without jamming.

On the other end of the rubber hose is a 16-inch pressure washer wand and attaches to any standard inch pressure washer connector. The nozzle attached to the pressure washer wand is made out of thick plastic with a replaceable ceramic tip.

For the price, this is a great pressure washer sandblasting kit, but it does have some drawbacks, while it will strip paint and rust, it can while you are using it clog up. The pipe with sucks sand out of your sand bucket can fill with water and the sand within gets stuck.

If you happen to own a Karcher pressure washer from their K Series (K2, K3, K4, K5, K6 and K7), then it is especially valuable, as this kit comes with an adapter specifically to fit this to a Karcher K Series.

This sandblasting kit includes a 10 foot-long sand hose, so you dont have to worry about a loss of suction, a plastic sand wand which like the above sandblasting kit, has been designed to suck up the sand from your sand bucket optimally. The sandblasting nozzle housing is made of a thick, sturdy plastic and hoses a replaceable ceramic nozzle.

With this kit, you get what you pay for, so dont expect to get much life out of the nozzle of the sandblaster. After a few projects and itll start to fail, at least that was my experience, though it was perfect for dealing with that single project before having to get a new kit for the next.

Why is this kit going to fail more frequently than the ones above? Well, unlike the previous kits which came with a ceramic nozzle tip, this comes with a brass nozzle tip and it just gets worn out much quicker.

The hose itself is attached to the sand wand and the spray nozzle by two clamps, this is an excellent feature as you can easily detach the hose from the sandwand and nozzle allowing you to dry the hose just in case any water comes down your sand hose.

Manufactured by Valley Industries, this sandblaster is made out of some very sturdy materials that allow it to handle up to 3500 PSI while not the highest pressure on this list, this will pair perfectly with one of these electric pressure washers.

The sand wand is made out of stainless steel and is made up of two tubes, one tube is for sand the other is for air intake, the reason this kit has two tubes is that this combination ensures an even and smooth sand flow.

Im sat here today because I forgot to put my eye protection glasses, which sit over my glasses on the other day when I was chasing out walls to run network cables. As I was using my SDS Drill to chisel out the remains after the chaser has cut to depth, small chunks of brick went flying towards my face, and well, my glasses are now sporting two large scratches. Thankfully my eyes were saved, but now Ive got to deal with scratched lenses.

So alongside your eye protection, you also get an adapter for the spray wand, this adapter can convert the standard inch quick connector of this pressure washer wand, into the bayonet fitting that fits perfectly into the Karcher K series pressure washers.

This pressure washer sand blast kit can handle up to 3200 PSI of pressurized water coming from your pressure washer and performs incredibly well as long as the water temperature remains below 140 degrees Fahrenheit.

The sand hose in this kit is made out of flexible plastic and comes in at 10 feet long, this is connected to a more robust, and studier plastic sand wand which is tapered to ensure optimal sand delivery.

Finally, theres the pressure washer wand which is made out of stainless steel, which on one end has a inch connector, on the other end theres a solid plastic nozzle with a brass gasket, the nozzle tip itself is ceramic so you dont have to worry about the tip failing on you.

This makes more than strong enough to handle all your domestic sandblasting projects. You get a very long PVC hose, this comes in at 18 foot-long. This is great, this length is in that perfect zone, ensuring that you get a steady sand flow, while that extra distance keeps your sand bucket well out of the water of water kickback, which reduces the chances of the sand clumping and blocking the feed.

Ive no doubt that there have been moments in your life when a sandblasting kit would have really saved the day, perhaps youve even spent hundreds of dollars on getting professionals in to do the sandblasting for you, thinking that its just not possible to do it yourself, well you can.

Sandblasting is exactly how it sounds, Its a powerful abrasive, you are literally blasting sand at a surface, this sand strips paint, rust, well anything that is the outermost layer is taken off of the surface.

Basically, if youve ever sanded something by hand or used a power sander such as an orbital sander, this is just a much more powerful option, thats quick and effective. No need to use sandpaper or a chemical paint stripper.

Typically to do this at home, youd need either a pneumatic tool such as an air compressor or a pressure washer. Apart from these machines, youll also need a sandblasting kit and a bag/bucket of sand or another sanding media.

So based on your circumstances and the needs of your project should dictate which one you go for, as I had a pressure washer already and I didnt own an air compressor, the decision was relatively easy.

For example, if the surface is made out of wood, then you probably want to choose dry sandblasting (I didnt..), even if the wood has been treated to handle moisture. This is because wood tends to blister or bend from exposure to excess water.

However, if you are sandblasting plastic, then wet sandblasting is your best choice because as plastics get hot, which they would from the friction of dry sandblasting, they tend to bend and change shape. However, the water from the pressure washer is a very effective way to prevent the surface from overheating.

Finally, if you are working with metal or masonry, then either method is suitable, though if you are using metal, make sure to dry the surface properly and apply an anti-rusting product if its the type of metal thats vulnerable to corrosion.

So asides from the reduced cleaning, theres also a health and safety aspect. If you are working in a populated area, I.e., near schools, office buildings or near your family home, you dont really want a dust cloud floating around.

Unfortunately with dry sandblasting thats precisely what youll get, sandblasting with an air compressor will result in a dust cloud, so make sure to wear the appropriate protective equipment, dont forget your lungs or your eyes.

With dry sandblasting, As you shoot sand onto the surface you are cleaning, every piece of sand shatters into multiple particles upon impact, as you are using air to propel them, these particles simply fly off into the air, leaving you and your project enveloped in a lot of dust.

However, when you use pressurized water to blast sand onto the surface you are cleaning, there isnt anywhere near as much dust. The water droplets catch the shattered sand particles, preventing them from wandering off. In fact, the added weight of the water helps make the particles fall to the floor immediately.

If you dont have a pressure washer or an air compressor and you are wondering which is a better choice, firstly what other jobs will you be doing? Will you need an air compressor for other tools? Or will you use a pressure washer more often?

Unless you are looking to purchase a commercial-grade pressure washer, air compressors are typically much more expensive than a water-based tool, you can use lower water pressure of around 1500 PSI for wet sandblasting, so those small, less powerful pressure washers can do the job.

This combination of water and sand quickly blasts these things away, leaving you with a clean and smoothed surface. Different materials can be used for wet water sandblasting and each one will provide a distinctive finish to the surface being cleaned.

Though there is a drawback, with this level of quality, durability, and reliability, they do cost more upfront, though youll save money and time in the long run as you wont be purchasing new tips for every sandblasting job you do and you wont spend your time replacing those tips.

Steel wears down quickly when exposed to the pressurized water and sand slurry. Unless the steel is actually stainless steel, it will also quickly corrode which will make it unsuitable for use with your pressure washer and actually increase the rate of wear.

The wand needs to be quite sturdy. So depending on your needs and your budget, you can opt for one made out of hard plastics, though personally, I would choose one made out of steel for longevity reasons.

Since you are working with a pressure washer, you need to make sure that there is adequate drainage nearby, this can be a drain, or you can work on soil or a lawn, wherever water can freely flow and get soaked up naturally.

Spread the tarp where you are going to work, and place the surface youll be sandblasting on top. As you work, the sand will fall onto the tarp. Once dried, you can run the sand through a sieve and reuse it for another round of sandblasting.

Pour your sand or other sandblasting media into a bucket or back and place it somewhere, where want wont reach it. Alternatively, you can use a bucket with a lid, Ive even seen people put an open umbrella over the sand to protect it from water.

On the other end of the metal wand is the hose and on the end of that hose will be the sand wand, this may be plastic or metal, take this and insert it into your sand bucket or bag. Or any other medium you intend to use for sandblasting.

Make sure that you get this right down to the bottom of the bucket, you want to ensure that the tip is above the sand level as it will need air, some kits have a sand wand and an air inlet to ensure an optimal mix of sand, air and water.

The powerful blasting comes with risks, bear in mind that any surface struck by this blast will suffer irreversible damage. Obviously, when we are sandblasting, we are expecting this. So make sure to be patient and controlled so nothing but the expected area is affected.

But you must keep in mind that you are operating a powerful machine. While sandblasting with a pressure washer is safe, you must respect it, its not a toy. So keep in mind all of the potential dangers.

If you are worried about safety while handling a pressure washer sandblasting kit, make sure to take the time to study the directions and use the instructions provided by your sandblasting kit manufacturer.

Water pressure is very important, but the amount youll need will depend entirely on the job at hand and the media you are using. If you have a lot of rust, well-stuck paint, or dirt you need to remove and you are using a coarse media, then you can use a pressure washer which can produce 1500 PSI or more.

A tip or rather a technique I use is to keep the sand bucket and sand wand elevated above my water wand, this way the water tends not to flow back down the sand inlet hose. If it does happen, its important to act quickly to salvage the situation; otherwise it can take a while before you can get back to it.

Its easy to wet sandblast. You take your pressure washer attach a pressure washing sandblasting kit. Take the kits probe and stick this into your sand bucket, this probe (line) is used to draw in the sand (or any other type of materials discussed in this article, being used as the abrasive substance) to the power washers extension wand, this is where the sand mixes with the water and is propelled towards the surface its being pointed at, at high speeds.

Bakingsoda which has beendesigned for soda blastingcanbe purchased from many industrialcleaningsuppliers for large projects or, for smaller projects, a small boxfrom the grocery storecan alsobe used.

This is done by attaching a kit to your pressure washer and sticking the kits prob into a bucket filled with an abrasive medium. When the pressure washer is activated, the movement of the water draws the sand up the probe line and mixes with the water.

Attach the pressure washer sandblasting kit to your power washer, follow the instructions of the power washer sandblasting kit, which will usually go something along the lines of, place the sand probe into the bucket with your abrasive medium (sand), attach the lance to your pressure washer trigger gun.

This is why using the best pressure washer sandblasting kit is the right solution for household needs. The water controls the dangerous silica dust and the price of entry is very low, while still doing a great job at removing whatever you are looking to get rid of.

Hopefully, Ive answered any questions that you may have had about sandblasting with your power washer. Ive done my best to find the most reliable information as well as give my own personal experience and to organize it all into this buying guide so that you can make the best pick from my list of pressure washer sandblasting kit reviews.

I have attached a pressure water sandblasting kit to my Pressure washer. I poured in 50 lbs of pool filter sand in the bucket and inserted the probe deep into the bucket . When I turn on the Pressure washer I only get water out. I get sometimes a small dash of sand that moves a little but never gets to the nozzle, so I get no media coming out. My only thought here is my sand must be damp ? can that cause me to not get any media to the nozzle? Thank you for any help Bob Hardisty

Though It sounds as if youve put the probe in too deep? the prob needs to be inserted into the sand bucket but the top of the sand probe still needs to be above the sand as these probes need air to do their job.

## from sandy beach to kaby lake: how sand becomes silicon | techradar

Strange things happen in forests especially Silicon Forest, as Hillsboro in Oregon has come to be known. That's where D1X, Intel's largest operational fabrication plant, is based and it's where what would have once seemed like a miracle of engineering is performed all day every day.

D1X is where processors measuring just 14 millionths of a millimetre across are made, ready to be shipped to motherboard and PC manufacturers all over the world. The amazing thing about D1X isn't the way Intel makes ever more diminutive processors, though. It's what they're made of.

There are more than 300 steps to turn sand into silicon, but you can group them into 10 key areas. If you can't imagine how the stuff you make sandcastles with can become a Kaby Lake processor, prepare to be amazed...

As you've probably guessed, chipmakers don't head for the nearest beach with JCBs or place bulk orders with the local builders' merchant. Normal sand and the sand used in the building industry is usually coloured red, yellow or orange due to the presence of impurities. What chipmakers need is silica sand, which you usually get from quarrying.

Silica sand is also known as silicon dioxide, and as you've no doubt guessed from the name it's a compound of silicon and oxygen. To get the silicon, the oxygen is removed by mixing it with carbon and heating it in an electric arc furnace to temperatures beyond 2,000 degrees C. At those temperatures the carbon reacts with the oxygen, becoming carbon dioxide and leaving pure silicon in the bottom of the furnace. That silicon is then treated with oxygen to remove impurities such as calcium or aluminium, leaving what's known as metallurgical grade silicon. That's up to 99% pure.

Unfortunately for the chipmakers, that still isn't pure enough to meet the requirements of microscopic microprocessors. So the metallurgical grade silicon is refined further, this time by grinding it into a fine powder, adding hydrogen chloride and heating it in a fluidised bed reactor at 300 degrees C. This creates a liquid silicon compound called tricholrosilane, and it also creates chlorides of unwanted elements such as iron, aluminium, boron and phosphorus. These are removed by fractional distillation and the trichlorosilane is vaporised in hydrogen at 1,000 degrees C. An electrically heated, ultra-pure silicon rod collects the silicon, and the result is electronic-grade silicon. Its purity: 99.999999%.

Electronic-grade silicon still isn't perfect, because it has a polycrystalline structure. That means it's composed of lots of small silicon crystals, and the joins between those crystals can suffer from defects known as grain boundaries. Those boundaries can cause chaos with electronic signals, so the structure of the silicon has to be changed.

The process of doing that is called the Czochralski Process, and it involves melting the silicon crystal in a quartz crucible at just over the melting point of 1,414 degrees C. A tiny silicon crystal is then dipped into the molten silicon, and it's drawn out while rotating constantly in the opposite direction to the rotation of the crucible. This attracts silicon from the crucible, creating what's known as a boule. A boule is a rod made from a single silicon crystal, and its size depends on the temperature, the rate of spin and the rate at which the crystal is pulled from the liquid. A typical boule will be around 300mm across.

The circular silicon rod is now cut into wafers, and those wafers are cut as thin as possible without making them incapable of surviving the fabrication process. The rod is cut with a device that works rather like an egg slicer, cutting multiple slices simultaneously to create wafers 0.775mm thick. The wire constantly moves and carries a slurry of silicon carbide, the same abrasive material that's used to make wet and dry sandpaper. The sharp edges of the wafers are then smoothed to prevent them from chipping.

Next up: lapping, where the wafers' surfaces are polished using an abrasive slurry until the wafers are flat to a tolerance of two thousandths of a millimetre. After that, the wafer is etched with a mixture of nitric, hydrofluoric and acetic acids to create an even smoother surface.

The super-smooth wafers will now be given an oxide layer, which is used to create the required features of the circuit. This is done selectively to specific areas, and may involve the use of ion beams, hot gases and/or chemicals.

Once such chemical is known as "photoresist", and it's broadly similar to the chemicals used to make photographic film. Unfortunately that doesn't cope very well with hot gas treatments, so the wafer needs to be masked. This is done by applying a patterned oxide layer that ensures the gases don't reach the photoresisted bits that the chip designer wants to keep.

## this machine crushes empty beer bottles into sand in just 5 seconds | digital trends

Two thirds of the worlds beaches are retreating as people across the world use non-renewable beach sand for construction, roading and other uses, Simon Smith, brand PR and digital manager for DB Breweries, told Digital Trends. We had some [conversations] over beers, and came up with an idea to crush glass bottles into a sand substitute that can be used in things such as construction, roading, even golf bunkers; meaning that we can keep our beautiful beach sand where it belongs: on our beaches.

New Zealand, Smith said, has a pretty impressive recycling rate, although theres always room to do more. To that end, DB Breweries has built several machines able to take empty bottles and turn them into substitute sand. All a drinker needs to do is deposit his or her bottle in the machine, which then uses miniature steel hammers to crush it into 200 grams of sand in only five seconds after extracting the plastic labels with a vacuum system.

Our sand will be processed through a screener which sorts it into a fine grades between 1.1 0.4mm particle sizes, he continued. Over the next few months, well be creating up to 100 tons of sand, which is the equivalent of 500,000 DB Export Bottles.The resulting sand substitute will then be given to our construction and retail partners to use in place of beach sand.

The ultimate goal is to provide a way of prompting people to recycle by giving them an image of what exactly it means to do so, rather than leaving it as an abstraction. Our ambition for the campaign is for people to have something tangible to think about, such as the love of our beautiful beaches, as a reminder to recycle, he said.

Material vertical fall into impeller which high-speed rotating from the machine top. Then, under the action of centrifugal, crushed by shunt impeller around material generate high-speed impact with the other part of umbrella-shaped. After hitting each other, the material will form an eddy between the impeller and casing, and repeatedly hit, friction and shattered each other. Material discharged vertically from the bottom, screening out the required finished product granularity by screening equipment.

Whole Center Feeding The material falls into the impeller through the center of the feed tray, and the initial lateral acceleration is given through the distribution cone, and is uniformly distributed into each flow passage to further accelerate the throwing. After the material is thrown, it will directly hit the material layer on the perimeter guard and the guard plate, or collide with the bounced material. This collision point is relatively close to the casing. The whole center feed has a stronger impact on force and longer stroke. Some materials impact the material layer of the peripheral guard plate and the peripheral guard plate, or the material is hedged, which is a hard landing, so it is advantageous for fine crushing. The whole center feed sand making machine is often applied to the processing of mechanism sand, and the sand formation rate is higher.

Center And Ring Feeding The waterfall flow feed is materials are processed by the distributor or points, and a part falls from both sides, and after falling, a continuous material waterfall is formed around the impeller. If only the material waterfall does not make any sense, which cooperates with the center feed. The accelerated material in the impeller is thrown out at a speed of 70-80 m/s, and the material falls into the material waterfall, causing the material to be milled. Of course, after the materials are exchanged for kinetic energy, some of the materials impact the perimeter guard or the material layer, and another part of the material falls. However, because the object of the first strong impact is the material waterfall. Therefore, the crushing ability is much lower than that of the whole center feed. But the friction and impact between the materials are increased. The center feeding with annular waterfalls falls feeding way is more suitable for shaping the aggregate and less wear.

Due to the natural resources is finite, many countries come to be a shortage of river sand. But construction industries need it. And nowadays various countries have issued documents banning the digging of river sand. So, artificial sand appearance not only solves this problem but also protect the environment.

The large rocks feed into need primary crusher(jaw/impact/hammer crusher) to reduce the size by vibrating feeder. But the crushing materials aren't enough fine, so they need to secondary crushing by sand making machine. In order to make full use of rocks, the sand making plant has a recycling system in primary and secondary crushing.

The artificial sand discharge by VSI sand making equipment should transport to sand washing plant to washing and screening, then dewatering and drying. Finally, we get the good manufactured sand for building materials, highway, railway, and concrete mixing plants. How to improve the artificial sand production? Please contact us, our engineers will design the sand plant on the basis of your information.
