The Rotary dryerproduced by Shuliy Machinery is an important part of the charcoal machine production line. It is mainly used for large-volume equipment. It has been sold to more than 30 countries and regions all over the world. The main markets are Africa and the Middle East. The airflow is in full contact with the material, but there are many mixing shafts and scrapers in the equipment, which can promote the material to be pushed forward while drying. Since the length of the drum dryeris long, the material can be completely dried from beginning to end.
For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption.Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, Rotary Dryers of the Indirect Heating Design can be furnished so that the heated gases will not come in direct contact with the material.
Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation concentrates, as well as chemical and industrial products. Frequently the saving of shipping weight so effected will pay for the dryer in a few months. Difficulties from freezing while in transit are also eliminated. Many industrial projects are now using Dryers for control and production purposes on many materials.
Three main types of Rotary Dryers can be supplied. The direct heat unit is used when it is permissible for the drying gases to come in direct contact with the material being dried. Partition plates increase the heating surface. Drying may be by hot air or exhaust gases from other operations. If this drying gas has a deleterious effect on the product, then an indirect type of dryer can be supplied. A further derivation is the Tedrow Steam Dryer.
Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.
The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is dried. All though it sounds simple there are problems that have to be solved before the required results are met. But first, so you know what we are talking about lets go through the design of a drier.
First is the KILN, this provides the heat, The BURNER is inside this portion. The fuel for the burner is usually diesel although heavy crude oil could be used in some cases. To be able to generate enough heat to dry the concentrate air must be added by way of a BLOWER. In front of the kiln is the point that the wet concentrate enters the drier. It is put into the revolving SHELL. The shell is on a slight incline. As the Concentrate is tumbled through the hot air mass of the drier it travels down this incline to the exit of the drier.
At this exit point the concentrate is either deposited straight into a storage area or taken to the storage area by a conveyor. It is also at this point that there is an EXHAUST HOOD. This provides a controlled escape passage for the fumes and water vapor that is generated by the concentrate drying. This is a very important function and the operator will have to be sure that it is open at all times. If it should become blocked the water vapor will not be able to escape. The concentrate will become wet and sticky which will result in the discharge plugging. The wet sticky concentrate will also lower efficiency level of the drier for an extended period of time. This happens because inside the drier shell are what are termed FLIGHTS these are flat pieces of metal that are bolted onto the shell.
They are there to lift the concentrate up to the top of the shells rotation and drop the concentrate through the hot air. If the water vapor isnt taken away, the concentrate becomes sticky from reabsorbing the water. This sticky concentrate will fill the spaces between the flights.
The concentrate will not be lifted and dropped through the hot air. This results in a long term condition of poor performance even after the initial problem has been cured. These flights will remain buried in concentrate. This removal of the water vapor is one of the functions of the blower. It assists the natural process of air movement as the hot air mass expands. To prevent the buildup of concentrate on the flights there are often CHAINS attached to them. As the drier revolves the chains slap the flights preventing concentrate from building up on dryers walls.
The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section. There are also two flat rings attached to the shell. These provide surfaces for support rollers to roll on. There is another problem that the inclined shell has, the incline causes the shell to want to slide in the direction of the incline. To prevent this additional rollers are attached to the last set of rollers.
Certain things in life are unavoidable and for any busy family, a pile of laundry is one of them. A rotary washing line can be a great way to keep on top of your washing with minimal fuss. Drying clothes and sheets outside gives your laundry a nice fresh smell and you can save on electricity bills by not using your tumble dryer as often. Plus the space-saving design of a rotary means you can hang out loads more washing than by using a normal clothes line whatever the size of your garden.
When it comes to recommendations for rotary washing lines on the Mumsnet forums, one brand comes up again and again Brabantia. Mumsnetters love the durability of the Brabantia rotary washing lines, and the manufacturer backs this up with a five-year guarantee, covering both the line and the included ground spike to fix it in your garden.
This model has a lift-o-matic system designed to hoist your washing up to 187cm off the ground, which is great for sheets and other large items. The 50-metre line length can take up to five loads of washing, it has integrated holes for clothes hangers, and the 6kg weight means its pretty easy to store it away in the winter, if you prefer.
If youre looking for something simple that will let you dry a full load of washing outside to get that fresh air smell, the B&Q three-arm silver effect rotary dryer is worth a look. The no-fuss design has three arms, which support 30 metres of lines. And when it's fully opened out, it measures 1.92 metres across so could be a good choice if you have a smaller garden.
It comes with a line tidy strap, to keep tension in the lines and stop them from drooping, and a plastic ground socket for installation using concrete so make sure you have somewhere suitable to fix it before you take the plunge.
The clues in the name you fix it to a wall rather than the ground, and it comes with the fixtures you need as well as clear step-by-step instructions detailing how to put it up. You just need to decide what height you want it to be when you're putting it up, then you fold it out when you need it, using the handy grip. It offers 24 metres of line space when it's fully unfolded, and its 184cm diameter should fit all but the tightest spaces. Once you're done, you can easily fold it back and use its protective cover to ensure durability.
Does your family produce a seemingly never-ending pile of dirty clothes and sheets that you struggle to find space to hang up and dry? In that case, the Home Laundry Company's Premium heavy duty 60m rotary washing line could be the one for you.
Its 60 metres of line and crank-handle hoist system can be used to hang out up to six loads of washing at once, to give you more of a chance of getting on top of your laundry mountain. Of course, even with the space saving design of a rotary dryer, this one will take up more room than others on this list it has three arms, and a whopping 3.16-metre diameter when fully extended, so make sure you've got room. It comes with the fixings you need to put it in the ground.
If the idea of digging a hole in your garden puts you off the idea of getting a rotary washing line, the Minky freestanding airer offers a neat solution. It has tripod legs to support the base so you don't need to put it in the ground and it can even be used indoors.
Got a cheap one from Wilko three years ago when we moved and weve had no probs with it so far. It has a cover and I bought a proper twist-in spike with a closing lid. It stays out (with cover on) all spring and summer and goes into the shed in autumn. I think if you look after it a cheap one will last ok, but I've never had an expensive one to compare!
As with most rotary airers, you can fold away the collapsible arms when you're not using it, so it won't spoil your view out the back window. The trade-off here is that the supplied plastic ground socket has mixed reviews for its durability, so if youre worried about its stability, you might want to buy a stronger metal spike separately.
Have you ever reached for your washing line and run your finger along it before hanging up your laundry, only to find the lines are a bit grimy? Well, the Leifheit Linomatic rotary washing line offers a handy solution to keep things clean: the lines automatically retract into the rotary arms when not in use, keeping them free from dirt, moisture and cobwebs.
It offers 50 metres of drying room, plus eight hooks for hanging shirts. Of course, it is a fair bit more expensive than others on the list, but the aluminium frame is lightweight and rust free, so you probably won't spend any time worrying about it once it's up.
Part of the attraction of rotary washing lines is the fact they are a real space saver compared to a traditional washing line. This three-arm rotary dryer from Brabantia hits the sweet spot for smaller gardens. Its 266cm diagonal span doesn't take up too much room, even when its fully extended, yet the 30-metre line can cope with up to three loads at a time.
Brabantia's rotary dryers have a good reputation for being well made. This models robust plastic ground spike keeps the dryer stable even in windy conditions and the rotating arms dry your washing quickly.
We have one. We use it a lot in the summer and a bit in the winter as you can leave things out there for days if you want. It's good just to not have to think about rain and leaving it out overnight.
As if doing the laundry isn't already a chore, the Great British weather (hi rain!) can make getting things dry even more of a challenge. That's why the Chimney Sheep Large Laundry Mac laundry protector could come in handy. It's a cover with a diameter up to 2.5 metres designed for rotary dryers to keep the rain off and let you leave the washing out longer.
Its a large circle of waterproof, breathable fabric that fixes to your rotary dryer. As well as a rotary dryer, you will need a clothes prop to extend from the centre of the dryer to keep the cover clear of your clothes. This can be bought separately.
The first thing to think about is the size of your garden, or whatever area you are thinking of using for your new rotary washing line. There are a range of different styles of rotary washing line, some of which need to be fixed in concrete while others can be driven into a lawn or garden theres more info about how these work below.
Depending on your needs, there are rotary washing lines to suit almost any budget, from about a tenner up to 100+. As you might expect, the more expensive models tend to be made from better materials and are likely to last longer, but this might not matter as much to you if you think you might be moving house soon, for example.
One of the benefits of rotary washing lines is that they fold away when not in use, but even the most compact fixed rotary washing lines need around 180cm square to be used. If you have a space that's even smaller than that, don't despair there are portable rotary washing line options that can be used inside or in a garage, as well as some that fix to a wall rather than into the ground.
Of course, the more space you have, the bigger the rotary washing line you will be able to consider. Some offer as much as 60 metres of washing line space enough to dry about six loads of washing in one go, but there's probably no point in getting one that size unless you think you will need it (the biggest ones take up about 3 metres squared when in use).
Traditional rotary washing lines are fixed into the ground using a ground spike essentially a plastic tube that is either driven into the ground or fixed in concrete. Many rotary dryers come with a ground spike included, but if youre concerned that your garden is in a particularly windy spot, it is possible to purchase more heavy duty metal fixings for some models. Just check the manufacturer's guidance to make sure it's compatible with the line you have chosen.
According to some Mumsnetters, using a heavy metal parasol holder (which you would need to buy separately) can be a way round having to dig a hole or use concrete to secure your rotary washing line. This seems to work well for lots of people and has the added benefit of being able to move it around but bear in mind it probably won't be as secure as fixing it properly in the ground.
As with any outdoor washing line, rotary washing lines can attract a bit of dirt and grime. The most expensive rotary dryers have retractable lines, which can help keep them clean, but if you need to give yours a wash, the easiest way is to use soapy water. Just dont do it when you have clothes up in case it stains your garments.
The best rotary washing line is the Brabantia Lift-O-Matic Rotary Airer Washing Line. Mumsnetters really rate the build quality of this brand. And the 50 metres of line combined with the lift-o-matic hoist system, means you will be able to get that lovely outdoor clean feel when drying more of your washing than you thought possible.
Because we know that theres nothing like real recommendations from real parents, we first headed to the Mumsnet forums to find out which rotary washing lines discerning Mumsnet users had bought. We compiled a list of rotary dryers they recommended, noting how effective they found them, and whether they were particularly good for any certain needs.
We then did some research across the wider web, looking at which rotary airers had won accolades or been featured in best buy lists across websites and print media, and what customers reviews said about them.

The rotary drier is used for compost pellets drying. There are moisture requirements for organic materials composition and pelleting. After compost granulation, granular fertilizer need drying for stocking and packaging. In ShunXin fertilizer machinery, there are common used fertilizer dries, rotary drier, and scraper type fluidize dryer for your compost pellets drying applications. The rotary drying facility is mainly used for powdery, granular or sticky composts drying. It features rotary drum structure and gear transmission system. ShunXin is a rotary dryer specialties Inc.
There are main three components consists of the entire rotary drum dryer. There is rotary dryer vent cleaner installed on the rotary drier. This design enables winds force into the machines drums. The drum design of the rotary drier enables the machine dry materials in a large capacity. Meanwhile it also let the fertilizer dry thoroughly with this rotary structure. The transmission gear can let the drier work efficiently. All the drier accessories are designed with leading material drying technologies. You can process your moisture granular composts safely and efficiently.
The dry air flows into the rotary drum through the furnace room. The burnt soot and the water vapor generated by the drying are discharged by the smoking dust removing device through the exhaust pipe. The gas temperature of the inlet cylinder is tested by a thermocouple on the feed chamber, and the furnace temperature is adjusted by controlling the amount of coal burned and the flow of natural wind. The material enters the rotating cylinder from the inlet, and the material is continuously flipped and thrown away, so that the material maintains good contact with the dry hot gas, and the heat exchange is achieved, so that the material can be dried. The cylinder of the dryer is supported on the retaining wheel device and the roller device by the front and rear rolling rings, and the retaining wheel on the retaining wheel device prevents the cylinder from moving forward and backward. The transmission is driven by the motor through the cycloid reducer to drive the simplified upper gear. Sealing device is arranged at both ends of the cylinder to prevent cold air from entering the cylinder and the combustion chamber into the cylinder of the flue gas, dust overflow, the cylinder, the feeding chamber and the discharge chamber. The collected materials can be cleaned.
Humidity is also one of the key issues for fertilizer plants to manage. Excessive humidity leads to equipment corrosion and affects the machines service life; in the production workshop, electrical appliances, over humidity fertilizers often cause electrical discharge or burnout; humid air is conductive, which may cause short circuit of electrical appliances and pose a threat to operators life and property. Humidity is one of the key problems that restrict the production of water-soluble fertilizer. Because in the process of water-soluble fertilizer production, some materials contain crystal water, which is easy to absorb moisture. The contact area between material and air in the production process is large, due to the high humidity in the air. It will cause agglomeration of water soluble fertilizer. Therefore, solving the problem of water-soluble fertilizer absorption is the current urgent task of enterprises. Facilitating a drier for your fertilizer plants is quite necessary.
The fertilizer itself is formulated from various salt crystals and a small amount of auxiliary materials. In the presence of moisture, a chemical reaction can take place between the ingredients of the ingredients to form a double salt and a solid tour. These reactions can even be extended to the finished product after packaging. Therefore, in the production of fertilizers, it is necessary to fully understand the compatibility between the raw materials, and if necessary, in the material pretreatment period, such as pretreatment of the superphosphate, to control the reaction of the release of crystal water inside the compound fertilizer.
Agglomeration is a property in which a substance changes from a loose state to a mass or a whole. This transformation, whether it is a finished substance or an amorphous substance, may occur. The agglomeration of fertilizer has a great relationship with humidity. When the surface of the material absorbs water, it will form a saturated guest liquid. After that, due to evaporation of water or absorption by other dry materials, the dissolved components will precipitate and precipitate crystals due to the surface of the material. The process of dissolution and recrystallization is continuously performed, forming a crystal bridge leading to agglomeration.
When the raw material absorbs water, some materials will be sticky, which will result in poor fluidity of the material. It is easy to hang on the side wall of the production equipment during the production process of the fertilizer, and the thicker and thicker, the flow layer and the blanking passage become smaller, resulting in poor feeding, affecting the stability of the ingredients.
ShunXin compost rotary drier for sale can dry organic fertilizers, compound fertilizers, and there are also some types of driers can dry organic materials, such as sawdust, sludge, any configurations, the company can tailor to you.

The Vulcan Drying Systems Frac Sand Drying System is custom-designed and manufactured to suit a customer's individual project needs. Most customers have sand ranging from 5-8% in moisture content. These drying systems consist of a rotary drum dryer and a burner mounted on a breeching plate. Vulcan Drying Systems Frac Sand Drying Systems are designed specifically to dry frac sands, making the material easy to transport, separate and handle.
Frac sand is fed into the rotary dryer. After passing through the dryer, the dried product is discharged to a transfer conveyor for further sorting and separation. The vapor from the process is pulled through a baghouse which removes fine particulates from the vapor stream.
Looking for a complete system to process your material? Vulcan Drying Systems designs and manufactures cost-effective solutions for any possible process. Our experienced team will create a system that will produce your desired result.
For years now, specialized sands known asfrac sands have been utilized to augment the production ofnatural gas and oil from wells. The mining and processing of sand for hydraulic fracturing (fracking) has grown into a booming industry in the Midwest.
Frac sand is used in the fracking process to create fractures in the rock to allow the free flow of oil, natural gas or natural gas liquids. The demand for frac sand is incredibly high, as a single well can use several thousand tons of the material.
The hydraulic fracturing process begins with the drilling of a well into a rock formation. A high-pressure fracking fluid is injected into the well. This fluid, made up of water mixed with frac sand and a blend of chemicals, acts as a propping agent, or proppant. The proppant prevents the fracture from closing and permits gas to flow through the well.
To ensure that the quality of sand is acceptable, mining companies wash and dry the frac sand to rid it of all possible impurities. Rotary dryers are the most proven and preferred method to dry frac sand. Dryers can be utilized at both the beginning and the end of the fracking process. Prior to its transportation to and use at a job site, frac sand must be dried and treated. Vulcan Drying Systems can supply a full range of equipment to dry, sort and move frac sand.
The rotary dryer also known as tumbling dryer is an equipment employed to minimize the moisture content of feed materials by bringing it in direct contact with a heated gas. It consists of an inclined long drum or cylindrical shell often fitted with internal flights or lifters; rotated slowly upon bearings through which the material to be dried flow with a tumbling/cascading action in concurrent (for heat-sensitive materials) or counter-current flow with the heating air or gases.
The movement of the material is due to the combined effect of inclination of the shell to the horizontal and the internal tumbling action or mechanical turn over thus the name tumbling dryer. The nature of the feed determines the directions of gas flow through the cylinder and it is relative to the solid. This drying equipment can also perform batch or continuous processing of the wet feed.
A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class. They are used when direct contact with the hot gas or air is not detrimental to the fed.
When high temperature is required for the drying process in a direct-heated rotary dryer, a combustion chamber is used and when low temperature is required on the other hand, for thermolabile materials, steam coil is used.
Although there is an infinite variation of rotary dryers, which present characteristics suitable for drying, chemical reactions, mixing, solvent recovery, thermal decompositions, sintering and agglomeration of solids, the main types of rotary dryers include;
1. Excessive entrainment losses in the exist gas stream is possible especially if the material contains extremely fine particles due to the large gas volumes and high gas velocities that are usually required.Get in Touch with Mechanic
