The mineral composition of limestone rock is mainly calcite or calcareous bioclasts (such as shells or biological bones, which are also composed of calcium carbonate), followed by dolomite, clay, silt, quartz, feldspar, glauconite, iron oxides, etc.

Limestone can be divided into grain-bearing limestone, micritic limestone, laminated limestone, biohermal limestone, chalk and so on according to its composition, structure, formation mechanism and impurities.

Because there are no rolling bearings and no screws in the grinding cavity, there are no such problems as damage to the bearings and their seals, as well as damage to the machine due to loose screws.

the most valuable things you need to know about gypsum | fote machinery

The general term gypsum refers to two minerals, raw gypsum and anhydrite. Raw gypsum is calcium dihydrate (Ca [SO4] 2H2O), also known as dihydrate gypsum or plaster. Anhydrite is anhydrous calcium sulfate.

It is a very important industrial raw material that is widely used in construction, building materials, industrial and artistic models, chemical industry (sulfuric acid production, paper filler, paint filler), agriculture, food processing, pharmaceutical, and many other industries and applications.

The plaster of Paris (also known as hemihydrate gypsum), divided into -type gypsum powder and -type gypsum powder, is formed from gypsum raw materials by heating at a high temperature of 105-200 .

The -type gypsum powder has good crystallinity and solidity, so it can be used in ceramic molds, sculptures, gypsum lines and high-end buildings. The -type gypsum powder is mainly used for mortar levelling, gypsum board production, painting, etc.

Gypsum powder can be used as Portland cement retarder in the concrete industry. In agriculture, because gypsum powder is alkaline, it is possible to sprinkle it into the acidic soil to integrate the ph value of the soil so as to make use of a lot of lands.

In the pharmaceutical industry, gypsum is the main medicine in the famous Chinese medicine " Baihu Tang ", which has a good effect in treating acute high fever and thirsty irritable. In addition, dentists use plaster to make models of gums, and surgeons also use plaster to repair the fractures.

Is gypsum harmful to humans? Is gypsum powder safe to eat? Will gypsum kill plants? Here is a video about how gypsum is used, including its uses in toiletries, food additive, fertilizer, chalks, etc. It also shows the process of gypsum.

In recent years, the gypsum industry has developed rapidly. Gypsum building materials are increasingly welcomed by the market and recognized by society with their applications becoming more and more widespread.

According to the US mining forecast, the world's gypsum demand will increase at a rate of 2.5% in the next few years. It is estimated that the world's gypsum demand will reach 300 million tons in 2030. The total annual consumption of the gypsum board will reach 2.04 billion square meters.

With the increase in the market demand for gypsum powder, the requirements for its production technology are getting higher and higher, so the price has risen accordingly. The price of gypsum powder is generally calculated in tons.

Its price varies with its accuracy and use. The price of gypsum powder is between $ 28.8-$ 403.6 per ton according to its whiteness and fineness. The cooked gypsum powder is about $ 28.8-$ 158.6 per ton, the cooking gypsum is about $ 72.1-$ 317.2 per ton, and the refined gypsum powder is about $ 201.8-$ 720.8 per ton.

1. The ex-factory price of Australian recycled gypsum is $ 35.00 per ton, plus $ 25 per ton freight, which is $ 60.00 per ton at the farm gate, and $ 10.00 per ton to spread. Its purity is measured at 17% S wet weight. Total cost of gypsum supply and application per ton of pure CaSO4.2H20 = (35+25+10) 18.6 17 = $ 76.59 per ton.

2. The ex-factory price of gypsum mined in New South Wales is $ 15 per ton, plus $ 40.00 per ton freight, which is $ 60.00 per ton at the farm gate, and $ 11.00 per ton to spread. Its purity is measured at 15% S wet weight. Total cost of gypsum supply and application per ton of pure CaSO4.2H20 = (15+40+11) 18.6 15 = $ 81.84 per ton.

The world's major gypsum producing countries are the United States, Iran, China, Brazil, Canada, Mexico, Spain, Thailand, etc. The United States, Brazil, China, and Canada are rich in gypsum resources.

The largest consumption area of gypsum is the building decoration material industry, which is mainly used to manufacture gypsum boards for construction and decoration. In many countries, the manufacture of slabs accounts for more than 80% of gypsum consumption.

The mining technology of gypsum ore is divided into two categories: the mining of fibrous gypsum ore and the mining of alabaster, ordinary gypsum and anhydrite mines. Due to the difference in physical and mechanical properties of the ore and surrounding rock, the mining technology of these two kinds of gypsum mines is very different.

Fibrous gypsum has low hardness and its rock consolidating coefficient is 1.2 for parallel fibrous gypsum and 1.5 for vertical fibrous gypsum. Because it is brittle, it will easily become fine ore to be lost. Due to the high price of the ore, most fibrous gypsum mines adopt the longwall method, selective mining and filling method.

The mining techniques of alabaster mine, ordinary gypsum mine and anhydrite mine are similar. The room and pillar mining method (generally 8-12 m in width) and breasting method are adopted. The drilling of gypsum ore is easy, but the explosive consumption is large, generally 0.34 kg/t.

The roller drilling rig is modern new drilling equipment. It is suitable for drilling operations of various hardness of minerals and rocks with the characteristics of high perforation efficiency, low operating cost, high mechanization and automation. At present, it has become a widely used perforation equipment in open-pit mines all over the world.

The excavator is composed of the power plant, working device, swing mechanism, control mechanism, transmission system, moving mechanism, auxiliary equipment, etc. The excavator can also perform pouring, lifting, installation, piling, ramming, and pile pulling operations after changing its working device.

After sieving with the vibrating screen equipment, the finished material conforming to the size is sent to the finished product area, while the large material is returned to the crusher for being crushed again until it meets the required size.

The common gypsum crushing equipment is the jaw crusher with a crushing ratio of 4-6. The jaw crusher, which is often used as the primary gypsum crushing equipment, can crush large pieces of gypsum into 150 mm particle size.

If the gypsum crushed by the jaw crusher cannot meet the particle size requirements, secondary gypsum crushing equipment such as cone crushers, hammer crushers, and impact crushers can be equipped to carry out further medium and fine crushing of gypsum. Specific equipment should be configured depends on the actual needs of the customer.

The crushed gypsum is sent to a ball mill for grinding until 90% of it is less than 149 m (100 mesh). The ground gypsum powder leaves the mill in the form of airflow and is collected in the cyclone separator.

The ball mill is mainly a machine for dry or wet grinding of the crushed gypsum. The machine is mainly used for repeated grinding of the raw materials in the barrel through the steel ball medium in the ball mill to complete the ball grinding operation.

The cyclone separator is suitable for purifying non-viscous, non-fibrous dry dust larger than 1-3 microns. It is purification equipment with simple structure, convenient operation, high-temperature resistance and low equipment cost.

Under the design pressure and air volume conditions, solid particles 10 m can be removed. At the operating point, the separation efficiency is 99%, and within 15% of the operating point, the separation efficiency is 97%. Under normal working conditions, the pressure drop of a single cyclone separator at the operating point is not greater than 0.05 MPa.

The gypsum material is lifted by an elevator and transported into the top silo of the rotary kiln preheater. Then, the gypsum material is evenly distributed into rooms of the preheater through the feeding pipe.

In the preheater, gypsum is heated to about 900 C by the flue gas of the roasting kiln at 1150 C, and about 30% of it is decomposed. Then, it is pushed into the rotary kiln by a hydraulic push rod, and -type hemihydrate gypsum (180240 ), anhydrous gypsum (350 ) and overfired gypsum (450700 ) can be produced.

The gypsum produced after calcining and decomposing in the rotary kiln is sent to the cooler to be cooled to below 100 C by the cold air blown in the cooler and discharged. The gypsum from the cooler is sent to the product warehouse via a vibrating feeder, bucket elevator, and belt conveyor.

Gypsum rotary kiln is a kind of thermal equipment for calcining gypsum. Its appearance and shape are similar to lime rotary kiln and cement rotary kiln. Its main structure includes kiln head, kiln tail sealing device, rotary cylinder, supporting device, back-up roll device, etc.

The finished gypsum clinker calcined in the gypsum rotary kiln produced by Fote has the characteristics of high taste, high purity, easy to control during the production process, high mixing degree of raw materials, uniform raw meal composition, high strength grade of the clinker, with less dust in the grinding process, less fly ash in the calcining process and reasonable price.

The large demand and wide application of gypsum powder have stimulated the prosperity of many industries and fields, so the production of high-quality gypsum powder is the general trend of the gypsum powder industry in the future.

where to buy stone dust - and what it is, how to use it

where to buy stone dust - and what it is, how to use it

After reading up on DIY hardscape projects, beginners often hit a roadblock when assembling supplies because they do not know where to buy "stone dust." There is much confusion over just what exactly this material is. At first glance,itprobably will not remind you of stone, nor are you likely to associate it with dust.

In fact, said confusion is partly responsible for the difficulty you may have in purchasing it. Establishments in your area that sell stone, landscape supplies, etc. may not sell a product that goes specifically by the name of "stone dust" but may carry a suitable product that is similar but that goes by a different name.

When stones are run through a crushing machine to make crushed stone, stone dust also forms. Its exact composition will depend on what kind of stone was run through the machine. For instance, sometimes granite is run through such a machine; in other cases, it could be limestone, for example. The machine has a screen that traps the larger material (that is, the crushed stone). The smaller material or "screenings" falls through the screen. Depending on the size of the holes in the screen used, it can be so fine in texture that it is basically a powder.This is what you are buying as "stone dust." But it may go by other names, such as:

Decomposed granite is one of the more recognizable names in this group. Technically, though, it is a different material, occurring naturally. Note that you will also find the terminology "stabilized decomposed granite." This just means that a stabilizer has been added to the product to make it less susceptible to erosion.

Another material name that you are bound to encounter when doing research for building patios, etc. is polymeric sand. This building material contains additives that give it the ability to function as a binding agent. For example, you could use polymeric sandto fill in the cracks between stones when building a flagstone patio. In such cases, you would apply water to this filler afterward to moisten said additives, thereby activating their binding properties.

Stone dust is widely used as asetting bed for any of the various types ofstone pavers(flagstone pavers such as bluestone being an example) used by homeowners in small projects. It can be smoothed to create a very flat surface and it is strong enough to support the weight of stone pavers, which can be quite significant.

Do note, however, that not everybody in the building trade would necessarily recommend stone dust as the first choice for such projects. Some observe, for example, that stone dust does not offer the best in the way of drainage qualities. Such objectors may prefer to use sand as a setting bed.

You can buy stone dust at most stone yards and quarries. Some excavation companies also sell it, along with the crushed stone, sand, gravel, bricks, flagstones, etc. that you might need for other projects. For a fee, most of these places will deliver the product to your property.

uses of limestone - know about the different uses of limestone

uses of limestone - know about the different uses of limestone

Limestone is a type of a sedimentary rock that is found naturally in the earths environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO3) in the form of calcite which is yet again a type of a mineral. It also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.

As for the physical properties, limestone usually varies between very fine-textured rocks and coarse-textured rocks. Further, there are many different types and names of limestone like chalk, coquina, travertine, tufa, fossiliferous limestone, lithographic limestone, oolitic limestone. They have been categorized based on how each rock is formed, how it looks, composition, and some other factors.

Construction. Well, architecture (or construction) is one space where they are dependent on limestone to a great extent. Interestingly, as this rock is so valuable and important, buyers are ready to pay even five times more than the value of the stone mostly for delivery. However, apart from architecture, there are several other uses of this rock as well. We will look at them in detail.

We have already said that limestone deposits contain mostly calcium carbonate compound. As such, this compound can be quarried to be used by the farming sector. Usually, limestone is crushed into smaller particles and various grades are produced. Finally, these products are sold as agricultural lime or Aglime which is again used to neutralize soil acidity as well as free up soil minerals like phosphates.

There are several industries that make use of limestone. As such, powdered limestone is used in the textile, paint, paper, rubber, glass and plastic industries amongst others. They are mostly used as fillers. Apart from this, it is used in the steel industry for the production process where limestone is used to remove impurities. The minerals found in limestones are also used in pharmaceuticals, cosmetic products, baking soda, toothpaste, etc.

Here limestone is quarried to service the needs of the building and construction industries. So the stone is cut into either slabs or blocks with specific dimensions. Some of its applications include sculptors, floor tiles, window sills, stair treads, and others. The famous pyramid of Giza in Egypt is made out of limestone.

Crushed limestone is used as a filter stone in on-site sewage disposal systems. Limestone in powdered form is also used as a substance to absorb pollutants or control coal mine dust at many coal-mining facilities. Lime which is the byproduct of limestone is used to neutralize acids and treat wastewater, industrial sludge, animal waste, and water supplies.

These are some popular uses of limestone. To know more about calcium compounds and other chemistry topics you can keep visiting BYJUS or download our app for interesting content and learning experience.

A limestone grinding plant consist of a complete set of machines. For example, there are crushers to crush the limestone to required sizes to feed into limestone grinding mill. Of course, you can also bought required sizes feed limestone from others. Besides, there will be feeding devices and conveying devices. The feeding devices can screen the feed limestone and reject the coarse ones. For the conveying system, it will convey the limestone to next phases of the limestone grinding plant. The core equipment for limestone grinding plant is the limestone grinding mill and classifier. The limestone grinding machine can be ball mill, wet grinding mill and so on. Paired with limestone grinding mill, the classifier can further cut the calcium carbonate powder from the grinding mill. As a result, the limestone grinding plant can produce different sizes of fine and ultra fine calcium carbonate powder for different uses. Since during the grinding process there will have dust, dust collectors are needed. Whats more, there are also silos to store raw material and final product.

Limestone grinding mill, together with air classifier, is the core equipment of limestone production plant. According to the ways to grinding calcium carbonate, there are dry grinding and wet grinding. Dry grinding of calcium carbonate means to grind required sizes of limestone in the mills. While the wet grinding refers to grind slurry form of limestone in the calcium carbonate grinding mill. Accordingly, there are two kinds of grinders: dry grinding mills, such as limestone grinding ball mill, vertical mill, roller mill, etc.; wet grinding mill, such as wet grinding vertical mill. The limestone grinding mill will grind the feed limestone in closed chambers. Since these grinders have different media balls, construction structures and so on, they can produce different optimum fineness powder. And combined air classifier, these limestone grinding mill can produced desired fineness of calcium carbonate. Daswell can offer you turnkey solutions for limestone grinding plant to meet customers needs.

After have an understanding of the limestone grinding plant machine, we will come to the limestone grinding process. Firstly, the great slumps of limestone will be crushed by primary and even secondary crushers to required sizes to be fed into the grinding mill. Then the feed limestone will be transferred to raw material silo through bucket elevator. From the raw material silo, the feed limestone will go into the limestone grinding mill with required amount through the feeding device. In the limestone grinding machine, the feed limestone will be ground and impacted by the ball media in the working grinding mill. According to the needs of desired fineness calcium carbonate powder, the limestone grinding mill will be set to operate for respective period of time. After this, the partially ground calcium carbonate will be blown into air classifier. In the classifier, with rapid turning of wheel, the partially ground calcium carbonate will be further cut into more fine powder. While at the same time, the coarse powder will be rejected and be returned to limestone grinding mill for second time grinding with raw material. The fine calcium carbonate powder then will be transferred to product silo through bucket elevator. And there the final ground calcium carbonate will be packed automatically or manually. In Daswell, the whole limestone grinding process can be controlled by PLC system. As a result, few operators are needed and they can monitor the whole process and make adjustment quickly if there is malfunction.
