Grind limestone to a specific surface area of 450 using the kind of pulverizer
The main component of limestone is calcium carbonate (CaCO3). Limestone powder has a wide range of applications, generally 0-3mm (coarse powder), 80-400 mesh (fine powder), 400-1250 mesh (ultrafine powder, 1250-3000 mesh (micro powder) between different fineness powders have corresponding application requirements.
Grinding limestone to a specific surface area of 450, this fineness is about 350 mesh, which belongs to the category of fine powder processing. MTW European version mill, VM vertical mill, TGM super-pressure trapezoidal mill and other mill equipment can meet its processing requirements.
MTW European version pulverizer: the fourth-generation Raymond mill upgrade equipment, which applies a number of independent patented technology property rights such as bevel gear integral drive, internal thin oil lubrication system, arc air duct, etc. The main models MTW110T, MTW138T, MTW175T, MTW215T , Stand-alone capacity: 3-50 tons / hour.
VM vertical mill: focusing on the three major fields of non-metallic ore, pulverized coal and slag processing, it integrates fine crushing, drying, grinding and transportation. Its main models include vm1300, vm1500, vm1700 and vm1900, with a unit capacity of 6-80 tons / hour. It is suitable for large-scale limestone milling production.
TGM overpressure trapezoidal pulverizer: Raymond mill series products are designed on the basis of high-pressure suspended roller mill and adopt five patented technologies such as trapezoidal working face, flexible connection and grinding roller linkage pressurization, mainly including tgm100, tgm130, tgm160 and tgm190, with a single unit capacity of 3-36 tons / hour.
The output of these equipments can be adjusted before 80-425 mesh. After continuous rolling and grinding, the limestone fine powder of about 350 mesh (specific surface area 450) can finally be selected.
