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 is, the slower the rotation speed will be. 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. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
Gold processing ball mill 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.
Gold processing ball mill Features:
1) Ball mill is an efficient tool for grinding many materials into fine powder.
2) Ball mill is widely used in ore upgrading production line, building material, chemical industry, etc.
3) There are two ways of grinding: the dry way and the wet way.
4) Ball mill can be divided into tabular type and flowing type according to different expelling mine
5) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
Customized size small mini diesel engine type ball mill is acceptable.
