Five Ways to Prevent the Abnormal High Temperature of Ball Mill Grinder
As we all know, due to the impact of grinding media, friction energy between the grinding material and ball mill, and the energy released when the material is ground, the ball mill grinder prone to excessive temperature phenomenon, and sometimes the working environment even as high as 40, 50 degrees in the summerThe most "efficient" fill level for a ball mill is to load material equal to 25% of the total volume of the mill A 40% batch will take twice as long to mill as does the 25% batch When the rotating speed of the ball mill exceeds a certain limit,the ball will rotate with the cylinder to rotate without falling in centrifugal running stateBall Mill PDF Mill (Grinding) Mining Scribd
