Overview

Coal ball mill is the equipment used for grinding and drying coal with different hardness. It is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system. The coal grinder is also widely used to break various hardness of coal in cement industry, metallurgy industry and chemical industry and so on.

Features
1. It is an efficient tool for grinding coal into fine powder.
2. The capacity and fineness can be adjusted by adjusting the diameter of the ball.
3. Low speed driving unit with lifting device, convenient for maintenance.
4. New endurable wear parts to increase service life of vulnerable parts.
5. Stable performance and easy installation.
