Abstract

The invention discloses a mining ball mill wear-resistant lining plate and a casting process thereof, and relates to the technical field of ball mills, the mining ball mill wear-resistant lining plate comprises a wear-resistant lining plate base plate, the top of the wear-resistant lining plate base plate is provided with a mounting threaded hole, the bottom of the wear-resistant lining plate base plate is fixedly connected with a stress reduction plate, the bottom of the stress reduction plate is connected with a hard reinforcing plate, and the hard reinforcing plate is fixedly connected with the wear-resistant lining plate base plate. A groove is formed in the top of the wear-resistant lining plate base plate. According to the wear-resistant lining plate disclosed by the invention, through the cooperation of the sound-absorbing plate, the positioning strip, the mounting groove, the stress reduction plate, the rubber cushion plate, the damping column and the hard reinforcing plate, the noise generated by the wear-resistant lining plate base plate in the ore grinding process can be reduced through the sound-absorbing plate, so that the noise is prevented from polluting the surrounding environment; and meanwhile, the positioning strips can prevent the sound absorption plate from shaking, the vibration frequency between the wear-resisting lining plate base plate and the mining ball mill can be reduced through the rubber cushion plate, and therefore vibration generated when the wear-resisting lining plate base plate is used can be reduced.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to a wear-resistant lining plate of a mining ball mill and a casting process thereof. Background technique [0002] The mining ball mill is mainly used for grinding materials. The materials enter the first chamber of the mill evenly from the feeding device through the feeding screw cylinder. The chamber is equipped with grinding bodies of different specifications. After the materials are crushed, they are screened by the separation device , qualified materials enter the second warehouse, and unqualified large-grained materials return to the first warehouse. The materials are coarsely ground in the second warehouse and then enter the third or tail warehouse. The tail chamber is equipped with steel forgings of different specifications, which will be coarsely ground. The materials are ground into qualified products, and discharged through the discharge grate of the hollow shaft to t...
