Limestone is a kind of resource with extensive use, which is often used as building materials, and it is also an important industrial raw material. Limestone can be used to produce silicate cement, the coating used for high-grade paper making, heavy calcium carbonate products as well as the production of plastics and paint. The processing technology of limestone is the mechanical grinding by the special powder grinding machine, and the heavy calcium carbonate can be produced after the grinding process of limestone.
Low energy consumption, long service life of limestone mill wearing parts;Its grinding roll and ring adopt special materials, thus greatly improve the durability of the limestone mill. In the case of same finished product fineness , the service life of wearing parts is 200%-300%longer than impact crusher and turbine crusher, which is generally up to one year or more; for the processing of calcium carbonate and calcite, its service life can reach up to 2-5 years.
Safe and reliable;The chamber of limestone grinding mill has no rolling bearing or screws, so there are no vulnerability problems of bearings and sealing devices or the damage of the machine resulted from screw loosening.
Fote Machinery is specialized in producing limestone mill which has more than 30 years production experience, and we also have marble grinding mill, clinker grinding mill, barite grinding mill, dolomite grinding mill, bentonite grinding mill and other stone flour mills for sale. The grinding mills of our company have high quality, reliable performance and reasonable price.
Limestone is one of the most versatile materials which are rich in resources. It is widely used in both industry and construction. Here were gonna to talk about the most common uses of limestonedesulfurization in power plants. When limestone is used to desulfurize power plants, what are the requirements for limestone grinding? What kind of grinding mill should we choose? Here we will introduce them to you.
Generally, not all limestone flour can be used for desulfuration. Limestone flour for desulfuration not only requires the fineness of powder but also the content of calcium carbonate. In addition, there are also regulations on environmental protection during the grinding production. In order to ensure the comprehensive utilization of desulfurized gypsum and reduce the discharge of sewage, the content of calcium carbonate in the limestone should be higher than 90% when its used for desulfurization.
Past experience shows that the fineness of the limestone flour (used for desulfurization) in power plants is generally required to be between 200 and 325 meshes. So it requires that the output size of grinding mill need to reach the standard. For the coal boiler which is low sulfur content in combustion, the fineness of the limestone flour should guarantee a 90% sieving rate of 250 meshes. When burning coal is with high sulfur content, the fineness of limestone flour should guarantee a 90% sieving rate of 325 meshes. Of course, you can also use quicklime (The purity of lime should be higher than 85%) as an absorbent.
When we have learned the fineness standard of limestone in grinding, there has relevant reference foe choosing grinding mill. Here we recommend 2 limestone grinding mill according to the popularity of market.
MTW New-type Raymond mill adopts unique sealing device which can prevent "running powder", meeting the requirements of powder fineness and the quality of the finished product can be controlled effectively. In addition, MTW New-type Raymond mill has been equipped with professional dust removal which can realize high dust removal efficiency and low emission concentration. So it is more conducive to meeting environmental requirements. The equipment adopts bevel gear integral transmission, which makes its structure more compact and versatile.
LM vertical mill integrates crushing, drying, grinding, powder selection, transport in one. The running process can be produced in one step which can reduce the investment greatly. The materials can stay in the mill for a short time, which can reduce the repetition of grinding; chemical composition can be better controlled as well. So the quality of the finished product is more stable. Meanwhile, there is no direct contact between the grinding roller and the grinder table, it ensuring the purity of limestone flour (low iron content), and this can meet the requirement on power plant desulfurization.
The limestone powder produced by the grinding mill of SBM has been applicate in desulfurization of various power plants well, and customers have achieved good economic benefits. For different limestone flour, we can provide you with different solution and relevant grinding equipment.

Limestone is a massive stone material that is mined by a limestone crushing plant through a limestone crusher. Its main component is calcium carbonate (CaCO3), and it also contains clay, dolomite, magnesium carbonate, iron oxide, silicon oxide and some organic impurities.
So what is limestone used for? Limestone itself can be used as a raw material in construction and industrial fields. Limestone can be made into limestone powder by treatment of limestone crusher and limestone grinding mill. Limestone powder can produce quicklime by calcination. Quicklime can be widely used for desulfurization in power plants, and after adding water treatment to get hydrated lime. By mixing hydrated lime, lime slurry and lime paste can be obtained, which are used for coating materials and processing materials of brick and tile adhesives. Powdered limestone made of limestone mill orRaymond millis also one of the raw materials of Portland cement.
First of all, large pieces of limestone are evenly fed to the limestone crusher machine by the vibrating feeder through the silo for primary limestone crushing. The limestone conforming to the fineness is sent out to the limestone crusher machine, while the limestone not conforming to the fineness is returned to the limestone hammer crusher for re-crushing.
Crushed limestone conforming to the feed fineness of vertical roller mill ( 110mm) is transported intovertical raw millor Raymond mill by bucket elevator. The limestone grinding process will start after the crushed limestone entering the mill.
1. The vertical raw mill is stable in operation, high in output, and easy to replace wearing parts. 2. The product quality of the vertical mill is stable. The chemical composition and fineness of the product can be determined and corrected quickly. 3. Large drying capacity. The vertical raw material mill adopts hot air to transport materials. By controlling the air inlet temperature, the product can reach the required dryness.
1. Ramon mill adopts a vertical structure and occupies a small area. 2. Ramon mill adopts electromagnetic vibration feeder, the feeder is uniform and easy to adjust. 3. Centralized control of electrical appliances enables unmanned operation. 4. Compared with other limestone mills, Raymond mill has a high screening rate, which can reach more than 99%.
