There are two kinds of grinding equipment for 400 mesh fineness as follows:
1.Vertical Mill
Vertical mill is a kind of equipment used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and many other industrial fields. The equipment consists of powder selector, grinding roller, grinding plate, pressure device, reducer, motor and shell. The main function of this machine is to pulverize the raw materials, and the discharging granularity can be adjusted within the range of 80~425 mesh. The discharging capacity of this machine can vary from 4 tons/hour to 400 tons/hour. Especially for non-metallic ore, coal powder, slag and other materials, the vertical mill has a good use effect.
2.High pressure suspension mill
Involved in the Mohs hardness less than 9.3, humidity less than 6% of metallurgical materials grinding, such as: iron ore, coal powder, blast furnace slag, power plant desulfurization agent, boiler coal injection, lime, feldspar, gypsum, barite, limestone, ceramics, slag and so on. The range of discharging granularity is 30~1000 mesh, and the discharging capacity can be 1~9.5 tons/hour.
