It is widely used in building material, chemical industry, etc. A Ball Mill The ball mill energy use factor is low, the distribution situation has the enormous relations with the material in grinding. Therefore discovered more approached the grinding machine outer layer, the abrasive action is bigger. When grinding machine actual production, the materials entered the mill to fall directly the inner layer, the process dynamics analysis, the inner layer material had to through the long time to enter the outer layer, reduced the production efficiency greatly.In order to cause the material to be quickly even, it has made the improvement to grinding machine feeding. First the old-style right angle feeding change the inclination angle type, then slide the angle to be bigger than stops the angle, will cause the material fast smoothly to enter. Then reasonable selection feeding spot, causes the material to enter the tube body outer layer directly.
