Ball mill is an efficient tool for grinding materials, generally 1/4 inch and finer, into fine powder particles around the size of 20 to 75 microns. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry or wet. It can be divided into tabular type and flowing type according to different expelling mine.
Ball Mills have been used to grind glass, powder food products, creat custom varnishes,make ceramic glaze, powder various chemicals, and make Black Powder.

A ball mill operates by rotating a cylinder with steel grinding balls, for the ball to fall back into the cylinder and onto the material to the ground. The material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours. 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 will be. If the peripheral 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. Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the Ball Mill runs.
