Cement 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 *0 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 Cement Mills usually operate at *5% to *5% of the critical speed.
Cement Mill is a key equipment to grind all kinds of ores and other materials.which is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Cement Mill are generally used to grind material 1/4 inch and finer, down to the particle size of *0 to *5 microns. To achieve a reasonable efficiency with Cement Mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from Cement Mills. Cement Mill is an efficient tool for grinding many materials into fine powder. The Cement Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc.
