Ball mill is an efficient tool for fine powder grinding. The Ball Mill is used to grind many kinds of minerals and other materials, or to select the mine. It is widely applied in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine.
To use the Ball Mill, 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. Obviously, the longer the Ball Mill runs, the smaller the powder will be. Ultimate particle size depends entirely on how hard the ground material is, and how long the Ball Mill runs. Our Ball Mills have been being used to grind glass, make ceramic glaze, powder various chemicals, and make Black Powder.
Ball Mill Features:
1) Easy and safe operation
2) Stable performance
3) Even product size
4) Low energy consumption
5) Low invest, high return
Ball Mill Working Principle
Ball mill is widely used for milling various kinds of ores or rocks in metal and non-metal mining and building material industry.The main bearing of the ball mill with the shell diameter 900-2100mm is spherical liner bearing; for the shell diameter 2700mm, the main bearing is completely closed self-aligning 120°bearing with strong alloy of high lead and low tin with low hardness, underneath laid with cooling copper piping full of water The bearing is of static pressure structure with high and low pressure united oil lubricating system.
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 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.
Ball mills are generally used to grind material 1\4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize continuously being recalculated back to the mill to be reduced.
