Therefore, various manufacturers produce a wide variety of ball mill linings. Plates, these are briefly classified below.

(1) According to the different positions of the mill mill liner in the installation position of the mill barrel, it can be divided into a head end cover liner, a cylinder liner and a door liner;

(2) According to the material of the ball mill liner, it can be divided into metal liner, rubber liner and cast stone liner;

(3) According to whether there is bolt connection between the ball mill liner and the cylinder, the liner can be divided into two types: bolt lining and boltless lining;

(4) According to the function of the ball mill liner, it can be divided into ordinary liner and graded liner;

(5) According to the shape of the working surface of the ball mill liner, it can be divided into: 1 flat lining: usually the flat surface or the patterned lining is classified as a flat lining, between the lining and the steel ball The main frictional force is that it has a small lifting effect on the steel ball. It is generally used for grinding operations with less fine grinding. 2 Long lining: This lining consists of a layered strip and a flat lining. The bolt on the bead fixes the bead and the lining on the cylinder, and the side of the bead and the plane of the lining have a larger steel ball

 

The lifting capacity, the steel ball has a large impact energy, this lining is generally used for rough grinding, and the disadvantage of the lining lining is that the height of the ball is not uniform, the steel ball near the bead is brought high, directly when falling Falling on the opposite lining, not only does not play the grinding effect, but also aggravates the wear of the lining; 3 step lining: the surface has an inclination angle, which makes it synthesize with the original friction angle. The advantage of the step lining is The height of the lifting of the same layer of steel balls is consistent, and the shape of the surface of the lining is not changed after wear, and it can be prevented.

 

Sliding and abrasion between the grinding bodies, such linings are usually used for rough grinding; 4 rib linings: this lining is to add semi-circular or trapezoidal ribs to the flat lining, which is rigid Large, not easy to deform, but the ribs are easy to wear, and the whole lining plate has to be replaced after wear; 5 Wave lining: After the rib of the rib lining is gently treated, it becomes a corrugated lining. The ability is weaker than the ribbed lining, mainly used for the support of the rod mill or baseball mill. In addition to these, there are Wedge shape, rudder shape, K type

 

Rubber and B-type rubber linings, etc.

The requirements for the lining of different grinding operations are different. Consult the manufacturer or refer to the same type of mine for selection of the ball mill lining.
