[0002] The existing ball mill cylinder liner is a cylinder with a diameter matched with a cylinder liner. The back of the liner is composed of a circular arc size, and this size is consistent with the inner diameter of the cylinder. When two ball mill cylinders with different diameters When the geometry of the working surface of the body liner is similar, the configuration scheme of the cylinder liner is very repetitive, the manufacturing cost of the liner is high, and there are many types of liners and a large inventory, which is not conducive to the common use and interchangeability of spare parts

Embodiment Construction
[0010] Refer to attached figure 1 , the back of the common liner used for two different diameter ball mill cylinders is composed of two arcs with different radii, R1 and R2. At the same time, R1 and R2 are also the radii of two different diameter ball mill cylinders. The large radius arc 3 is set In the central part, the two arcs intersect at points 1 and 2. This liner is installed on the cylinder of the ball mill with a radius of R1. The contact surface is the arc area 3, and the arc areas 4 and 5 at both ends are theoretically compatible with the cylinder. The body has a gap f; it is installed on the ball mill cylinder with a radius of R2, the contact surface is the arc area 4 and 5, and the middle arc area 3 theoretically has a gap e with the cylinder. The positions of the intersection points 1 and 2 of the two arcs on the back of the liner are determined according to the contact area between the liner and the barrel of the ball mill with two different diameters and the gap...

The invention relates to a shared lining plate for two ball mill cylinder bodies with different diameters. The shared lining plate is characterized by being used for the two ball mill cylinder bodies with different diameters; a back surface comprises two different arcs; the arcs are respectively consistent with the inner diameters of the corresponding ball mill cylinder bodies, the large-radius arc is arranged on a central position, and the small-radius arcs are arranged at both sides of the large-radius arc. After the shared lining plate is installed, the shared lining plate has certain contact area with the ball mill cylinder bodies so as to be firmly and tightly attached, gaps between a non-contact part and the inner walls of the ball mill cylinder bodies cannot influence the normal use of equipment. The shared lining plate disclosed by the invention is reasonable in design, reduces the manufacturing cost, reduces the spare part stock, reduces the management cost and realizes the generality and exchangeability of the parts of the equipment.
Description
technical field [0001] The invention relates to a liner for a ball mill cylinder, in particular to a common liner for two ball mill cylinders with different diameters. Background technique [0002] The existing ball mill cylinder liner is a cylinder with a diameter matched with a cylinder liner. The back of the liner is composed of a circular arc size, and this size is consistent with the inner diameter of the cylinder. When two ball mill cylinders with different diameters When the geometry of the working surface of the body liner is similar, the configuration scheme of the cylinder liner is very repetitive, the manufacturing cost of the liner is high, and there are many types of liners and a large inventory, which is not conducive to the common use and interchange of spare parts. Contents of the invention [0003] The purpose of the present invention is to provide a common liner for ball mill cylinders with two different diameters. Its application can reduce the manufactu...
