Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back in to the cylinder and onto the material to become ground. The rotation is usually amongst 4 to 20 revolutions per minute, depending upon the diameter in the mill. The bigger the diameter is, the slower the rotation is. When the peripheral speed of your mill is also great, it starts to act like a centrifuge and also the balls tend not to fall back, but keep on the perimeter of your mill. The point exactly where the mill becomes a centrifuge is named the “Critical Speed”, and ball mills typically operate at 65% to 75% in the important speed.
The Energy-Saving Ball Mill is really a horizontal rotating device transmitted by the outer gear. The materials are transferred for the grinding chamber via the quill shaft uniformly. You will find ladder liner and ripple liner and different specifications of steel balls within the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and influence and grind the materials. The ground supplies are discharged through the discharging board therefore the grinding procedure is finished.
Ball mill is mainly composed of charging and discharging, cyclone and rotation components (like redactor, minor rotation gear, motor, electric machine, etc). Hollow axis is made from steel parts with a lining replicable. Key rotation gear, machined by rolling wheel of casting, is lined with wearing plate with fine wear-resisting property.This machine runs stably and reliably. According to difference of materials and discharging sorts, dry Ball mill and wet Ball mill are selectable.
