[0005] To realize the above-mentioned purpose, the utility model provides the following technical scheme: a kind of cement ball mill is with super thin lining structure, including mounting bracket, ball mill barrel, motor one, motor two, hydraulic rod, closure cap and lining body, the ball mill barrel one end and closure cap side are all provided with support shaft, the support shaft of ball mill barrel one end is rotatably installed in mounting bracket interior, the support shaft of closure cap side is slidably installed with the sliding sleeve embedded in mounting bracket interior, the hydraulic rod telescopic end is connected with support shaft, the inner wall of ball mill barrel is provided with multiple groups of annular array distribution's lining body, the ball mill barrel upper end interior is provided with installation groove, the ball mill barrel one end is provided with motor two, the mounting bracket one end is provided with motor one, and the output end is connected with support shaft, the one end of lining body is provided with the positioning rod of symmetrical distribution, the one end of lining body is provided with the positioning hole of symmetrical distribution.

[0006] When the ultra-thin lining plate structure for a cement ball mill is used in the scheme, the closing cover slides in the sliding sleeve through the support shaft, and one end is rotatably installed with the closing cover through a bearing. The closing cover can rotate, and the support bearing plays a role of guiding the closing cover to slide horizontally. Under the drive of the hydraulic rod, the support shaft slides in the sliding sleeve, drives the closing cover to move, and then the closing cover is closed with the ball mill cylinder through the embedding of the embedding block and the embedding groove. The cement raw materials are transported into the ball mill cylinder through the feeding pipe, and then the control valve is closed. The motor drives the support shaft at one end of the ball mill cylinder to rotate, drives the ball mill cylinder to rotate, and the grinding body and the cement raw materials flow in the ball mill cylinder. The cement raw materials and the grinding body impact each other to grind and process the cement raw materials. When grinding, the ball mill cylinder contacts with the side lining plate one, the side lining plate two and the lining plate body to protect the inner wall of the ball mill cylinder and the closing cover.
