Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the 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. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
Applicable materials
Ball Grinding Mill
The ball grinding mill is the key equipment for crushing the material after it is broken. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal mineral processing and glass ceramics and other production industries, for a variety of ores and other grinding materials dry or wet grinding. Ball mill is suitable for grinding all kinds of ores and other materials, which is widely used in mineral processing, building materials and chemical industry.

Working principle
Working principle
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
When the materials processing, they are transferred to the grinding chamber through the quillshaft uniformly. Firstly the centrifugal force caused by rotation of barrel brings the steel ballsto a certain height, then the steel balls impact and grind the materials into fine powder overa period of several hours. The ground materials are discharged through the dischargingboard ,lastly the grinding process is finished.
