Ball Mill

Ball mill is one of the most widely used superfine grinding equipment in mining industry. Ball mill has many types, such as, tube ball mill, cement ball mill, superfine ball mill and energy-saving ball mill, overflow ball mill, chinaware ball mill and grid ball mill. Ball mill is mainly used to grind materials in mineral, cement, refractory, chemical  and other industries, with dry and wet two ways.

Working principle

Ball mill is composed of horizontal cylinder, hollow shaft and grinding head. The long cylinder is made up of steel, and equipped with grinding system. Materials will be sent into the cylinder according to different diameter and certain percentage. The shell rotates to generate eccentricity which can bring balls to a certain height, then balls drop down by gravity, so the impact means the grinding force between balls and matrials.

Structure

Ball mill is composed of feeding part, discharging part, rotation part and driving part (gear box, small transmission gearwheel, motor and electric control). The hottest ball mill contains cylinder with wearable liners, which maintains the rotating of cylinder and the driving devices, such as, motor, transmission gear, pulley, belt, etc.
