Hydraulic system in raw mill/VM vertical milling machine

Introduction of raw mill:

It has many advantages such as, strong adaptability, continuous production, large crushing ratio, easy to adjust the size of the products.
Raw mill is mainly used in grinding raw materials and final products in cement plant. It is also suitable for grinding various ores and other materials in the metallurgy, mine, chemical, construction and other industries. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator. It is widely applied in many industries and has convenient operation.

Usage of raw mill:

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

Sorts and features:

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.
Air-swept mill: The feature of air-swept is sort 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 redidtance and drying capacity is strong since large amount of hot air could get in.
Outlet discharging&lifting cycle mill: Comparing with air-swept mill, materials, passing through the drying chamber, are discharged at the outlet of grinding cnamber by mechanical way, and then fed into seperator by elevator which woud return the coarse materials to mill again for cycle grinding.
