Principle and Precautions of Ball Mill Design

Any manufacturing or ball mill skilled operators have a very understanding of the structure of the ball mill cylinder, which certainly involves a lot of attention and principle of the problems, ZK Corp has been specifically for the ball mill design to develop detailed precautions and principles, to help ball mill operators quickly get started operating the ball mill, both safe and secure.

The barrel body of the ball mill is composed of a cylinder, flange, lining plate, screw and manhole cover. Ball cylinder is the main part of the ball mill, is welded by the ball mill plate.In order to facilitate the replacement of ball mill liner and check the situation inside the cylinder, the ball mill on the left cylinder with two symmetrical manhole, manhole sealed with a lid, and the lid is fixed with a screw on the cylinder. The two ends of the barrel of the ball mill are welded with flanges. The ends of the flanges and the end caps are brought into contact with each other and are positioned with pins. Then, the bolts are tightened evenly. Ball mill liner with the bolt together in the cylinder, in order to prevent the pulp grinding bad cylinder shell, liner in the ball mill cylinder staggered arrangement. Ball mill liner and cylinder pad between the heat-resistant alkali-resistant rubber sheet, a buffer ball on the impact of the ball mill cylinder and help the liner and the ball cylinder wall close fit role.

In order to prevent material from flowing out along the screw holes, a sealing ring and a tapered washer are placed under the nut. Ball mill liner in addition to protecting the ball mill main parts are not worn, it also has to enhance the role of the media. Ball mill cylinder design principles: the choice of ball mill steel material is better; arrange the principle of the ball mill steel plate; for the larger diameter of the ball mill cylinder, if the department of its circular weld, arc theory, and the central plate should choose the appropriate thicker. The inner surface of the barrel shall be smooth. Ball mill cylinder liner plate and fixed plate of the bolt holes should be based on the liner size equidistant from the opening, vertical and horizontal in order to facilitate the processing.

The manhole on the cylinder of the ball mill should be in the middle position of each bin, and the manhole of each storehouse should be staggered along the bus line of the cylinder, so that there is a large margin for the adjustment of the position of the storehouse. Benefits are easy to load and unload grinding body. The role of the ball mill barrel is to make the parts and people can freely access, easy maintenance, so its size should not be too small, but it should not be too large.
