ftm grinding mill for calcium carbonate, limestone---limestone mill - fote machinery
FTM limestone grinding mill is the star product of Henan Fote Heavy Machinery Co,.ltd.and it is a grinding mill is specialized in limestone grinding.With genuine components provided by world famous manufacturers and advanced technologies, FTM limestone grinding mill is your best choice to supply limestone powder for portland cement production,high-grade paper making materials, coatings and calcium carbonate products and so on.
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.

Our automatic production line for the grinding cylpebs is the unique. With stable quality, high production efficiency, high hardness, wear-resistant, the volumetric hardness of the grinding cylpebs is between 60-63HRC,the breakage is less than 0.5%. The organization of the grinding cylpebs is compact, the hardness is constant from the inner to the surface. Now has extensively used in the cement industry, the wear rate is about 30g-60g per Ton cement.
Grinding Cylpebs are made from low-alloy chilled cast iron. The molten metal leaves the furnace at approximately 1500 C and is transferred to a continuous casting machine where the selected size Cylpebs are created; by changing the moulds the full range of cylindrical media can be manufactured via one simple process. The Cylpebs are demoulded while still red hot and placed in a cooling section for several hours to relieve internal stress. Solidification takes place in seconds and is formed from the external surface inward to the centre of the media. It has been claimed that this manufacturing process contributes to the cost effectiveness of the media, by being more efficient and requiring less energy than the conventional forging method.
Because of their cylindrical geometry, Cylpebs have greater surface area and higher bulk density compared with balls of similar mass and size. Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power.
