The Function of a Ball Mill . To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is suspended on its axis ...
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.
Duralox ceramic mill lining bricks protect the steel ball mill shell and provide high purity grinding. Following features and benefits are worth considering while using Duralox Ball Mill linings for milling substances of hardness below 9.0 Moh's scale :
Ball mill classification production line output; In actual production, in order to maximize the benefits, the output matching of the ball mill and the classifier is very important. Proper cooperation can give full play to their own characteristics, complement each other's advantages, and are highly efficient.
