cement ball mill

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 mining, 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. It has many advantages such as, strong adaptability, continuous production ,large crushing ratio ,easy to adjust the size of the product.

Working principles of cement ball mill:

The raw mill uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials.
Feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers. Coarser material and bigger humps drops through the nozzle ring – and is eventually recirculated into the feed material inlet.
Moisture evaporates almost immediately as the gas stream carries the finer portion of material to the separator. The separator allows material that has reached the required fineness to leave the mill and sends oversized material back for further grinding.

Advantages and Features of cement ball mill:

High-performance separator and optimized airflow ensure high separation efficiency and low pressure loss for energy savings

Unusually large rollers permit coarse feed and ensure a thick grinding bed for maximum uptime

All impact forces and dynamic reactions are small and vertical and thus easy to accommodate – prevents mill stops

Segmented wear parts for table and rollers allow use of the most wear-resistant materials and/or hard facing for long life

Reversible roller segments ensure high material utilization

External circulation limits fan power consumption

Feed sluice ensures low false air flow and steady feed flow for minimum power consumption and optimum mill production

The raw mill is easily adaptable to high airflow required by especially wet or easy to grind materials
