Liner plate structure for mining ball mill

Abstract

The invention discloses a mine ball mill liner structure, which comprises a cylinder body, an impact-resistant steel plate layer, a magnetic plate and a bearing assembly; a liner plate is arranged inside the cylinder body, and an elastic inner wall is arranged inside the liner plate; There are grinding balls; the outer side of the liner is provided with a reinforcing plate, and the outer side of the reinforcing plate is provided with a hard foam layer; the outer side of the hard foam layer is an impact-resistant steel plate layer, and a magnetic plate is also arranged inside the impact-resistant steel plate layer. The cross-sections of the magnetic plate and the cylinder are both cylindrical; bearing assemblies are provided at both ends of the cylinder; in the present invention, the elastic wall can increase the number of material collisions, increase the grinding effect, and buffer the grinding ball against the lining. At the same time, when the cylinder rotates, under the action of the magnetic attraction of the magnetic plate, the grinding ball follows the cylinder to rotate to a higher point, obtains a large potential energy, and then falls, during the falling process, The force between the grinding ball and the liner is greater, and the impact force on the material is greater, which improves the work efficiency.

Description

technical field [0001] The invention relates to mining equipment, in particular to a mine ball mill liner structure. Background technique [0002] At present, the mixing of abrasives in the industrial field mainly adopts the method of ball milling, that is, relying on the ball mill for crushing and shaping. The traditional ball mill includes a ball milling tank and a power device. The ball milling tank adopts a drum structure. Driven by the power device, the ball milling tank can rotate at high speed. When working, put the abrasive into the ball mill tank. Since there are grinding balls such as steel balls or ceramic balls in the tank, under high-speed stirring, the impact between the grinding balls and the inner wall of the tank, and between the grinding balls and the grinding balls drives the tank. The abrasives of different components in the body reciprocate, and the abrasives are broken and shaped, so that the abrasives can achieve the purpose of dispersion; [0003] In...

Problems solved by technology

[0003] In the prior art, the inner wall lining plate of the grinding device is thickened by the ball milling tank, but with the prolongation of use time, the grinding device will still be damaged due to severe impact force
