Grid lining plate for ball mill

Abstract

The invention discloses a grid lining plate for a ball mill. The grid lining plate comprises lining plate bodies. A plurality of ore discharging through holes are formed in the middle portion of each lining plate body. A connecting part extending outwards is arranged at the lower portion of the left side wall face of each lining plate body and provided with connecting through holes. A groove for the connecting part of the adjacent corresponding lining plate body to be inserted is formed in the lower portion of the right side wall face of each lining plate body. Through holes are formed in the top faces of the grooves. A microscler groove is formed in the upper portion of the right side of each lining plate body and communicates with the corresponding through hole. Inserting grooves are formed in the two side walls of each microscler groove. Microscler stop blocks are inserted in the microscler grooves in a sleeved manner. Protruding strips on the two sides of each microscler stop block are embedded in the corresponding inserting grooves. By means of the grid lining plate, gravel can be discharged out of the ore discharging through holes; and meanwhile, the microscler stop blocks are arranged to protect bolts against damage, subsequent dismounting and maintaining of the lining plate are convenient, and the effect of the grid lining plate is good.

Description

[0001] Technical field: [0002] The technology of the invention relates to the technical field of ball mill equipment, and more specifically relates to a grid liner for a ball mill. [0003] Background technique: [0004] Ball mill is a kind of grinding equipment widely used in the fields of electric power, ceramics, cement and mineral processing. Its basic working principle is: the cylinder of the ball mill rotates at a certain speed, and the grinding balls at the bottom of the cylinder of the ball mill are attached to the lining plate of the cylinder under the action of centrifugal force and friction. When the grinding ball is brought to a certain height, it is thrown down due to its own gravity, and the abrasive material at the bottom of the cylinder is impacted and crushed and ground. The liner of the ball mill is used to protect the cylinder from the direct impact and friction of the grinding body and the material. At the same time, different forms of liner can be used t...

Problems solved by technology

[0005] However, the severe impact of the grinding balls on the liner of the ball mill will cause the liner to wear and thin, causing problems such as non-wear resistance, easy breakage, and unsatisfactory dribbling effect, resulting in low work efficiency, low output, and virtually increased costs.

[0006] In particular, the existing ball mill grid liner is generally fixed on the cylinder by bolts, and there is a gap between the through hole of the fixing bolt and the bolt, and gravel, powder, etc. will enter in the gap and the bolt and gravel will be separated. Direct collision with the powder will easily damage and deform the bolts, which will make the subsequent disassembly and maintenance of the lattice lining more difficult and impossible to disassemble, which is very troublesome
