Product Detailed

Widely used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals.

  

Ball mill grinds materials by rotating a cylinder with steel grinding balls, causing the balls to fall into the cylinder and onto the materials to be ground. The rotation is usually between 4to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation is. 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.

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 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 ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kind of mine and other materials, or to select the mine. It can be divided into tabular type and flowing type according to different forms of discharging material.
