1.Usage:

Raw material mill is used widely for grinding (both drying and grinding) cement raw material and other materials in buinding material, metallurgical,electric and chemical industries.

2.Sorts and Features: 

a. Common Raw Mill It is used for small & medium-sized raw materials grinding system which generally is cycle flow system with material separating system outside the mill.

b. Air-swept Mill The feature of Air-swept mill is short and thick in shell , wide in diameter of inlet & outlet trunion, large in grate gap area of diaphragms between drying chamber & grinding chamber, no grate plate in mill outlet.Therefore, air speed inside of mill could reach 5m/s due to small resistance and drying capacity is strong since large amout of hot air could get in.

c. Outlet Discharging & Lifting Cycle Mill Comparing with Air-swept Mill, materials, passing through the drying chamber, are discharged at the outlet of grinding chamber by mechanical way, and then fed into seperator by elevator which would return the coarse materials to mill again for cycle grinding.

d. Middle Discharging & Lifting Cycle Mill From the view of drying, it is the combination of Air-swept Mill & Outlet Discharging & Lifting Cycle Mill; from the view of grinding, it workssimilar to secondary stage cycle grinding system. At the front end, it has drying chamber with high drying efficiency. Materials are fed from mill inlet, returned materials from seperator are fed through mill inlet & mill outlet into rough grinding chamber & fine grinding chamber respectively.

Note：

1. Weight of grinding media ball is not included. 

2. Ф2.2~Ф3.2 serials rolling bearing mill could be supplied as per the requirement of customer. 

3. When placing order, please indicate the motor voltage & driving mode (Dextrorotary or levorotatory type: if no indication, manufacturer will supply equipments in dextrorotary).
