### What Is A Ball Mill What Are Its Uses And Advantages

mar 09, 2021 If the peripheral speed of the ball grinding mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. my whatsapp:0086 oct 31, 2019 At this time, the grinding effect is better and the wear of the ball mill machine is also reasonable. the theoretical critical speed of ball mill machine is generally 78% 85%. due to the nature of materials and other factors, the rotate speed of the ball mill machine should be determined according to the actual situation.sep 07, 2011 As a general rule, the speed of ball mill mainly from the basic power distribution equipment and gear drive gear and pulley device control.for large ball, since the drive motor to start the beginning of a great loss when the energy, and because the ball inertia force can not effectively use reducer mill to effectively control the speed in a
