Description

Lining plate of ball mill and ball mill Technical Field The utility model relates to the technical field of ball mills, in particular to a ball mill lining plate and a ball mill. Background The market at present is that the main stream products of the lining board of the ball mill are lining boards made of materials such as high manganese steel, alloy steel, high chromium cast iron, rubber and the like. The material is simple to process and mold once, the production is simple and the cost is low, but the service life is short, and the service life is generally only 4 to 6 months. One of the main reasons that cermets have not been used in ball milling liners is that cermets are not suitable for use as large and thin pieces during pressing and sintering, and the liners are both large and thin pieces, with a length of greater than 500MM and a thickness of about 80 MM. The pressing area is large, larger pressure is needed, the tonnage of a common press is insufficient, the pressed press is easy to crack and break after being carried, and large and thin pieces are easy to deform or crack due to temperature stress in the sintering process, so that the ceramic production process is not suitable for producing large and thin pieces. Disclosure of utility model The utility model aims to solve the technical problem of providing a ball mill lining plate with long service life and a ball mill. The technical scheme adopted by the utility model to solve the technical problems is as follows: A lining plate of a ball mill comprises a lining plate base layer and at least one pair of transverse metal ceramic groups oppositely arranged on the lining plate base layer, wherein each transverse metal ceramic group comprises one row or at least two rows of ceramic groups, each ceramic group comprises at least two parallel metal ceramics, a transverse fixing groove is formed in the bottom of each metal ceramic, and a transverse extending block extending into each transverse fixing groove and matched with each transverse fixing groove is arranged on the lining plate base layer. In one embodiment, the cermet is trapezoidal and elongated, and the transverse fixing groove is a C-shaped transverse groove. In one embodiment, a transverse steel plate is arranged between the two transverse metal ceramic groups and the lining plate base layer. In one embodiment, the transverse steel plate is provided with at least two steel plate through holes communicated with the transverse fixing groove. In one embodiment, the transverse steel plate is provided with at least two steel plate half through holes communicated with the transverse fixing groove. In one embodiment, the steel plate through holes are positioned between adjacent cermets, and the diameter of the steel plate through holes is larger than the distance between the adjacent cermets, so that the transverse fixing grooves are communicated with the lining base layer through the steel plate through holes. In one embodiment, the steel plate half through hole is located between the end of the metal ceramic transverse end and the joint of the lining base layer, and the radius of the steel plate half through hole is larger than the distance between the end of the metal ceramic transverse end and the joint of the lining base layer, so that the transverse fixing groove is communicated with the lining base layer through the steel plate half through hole. In one embodiment, lifting strips extend between the two transverse metal ceramic groups and above the lining base layer. In one embodiment, the middle part of the lining board base layer is provided with at least two mounting holes penetrating through the lifting bars. The technical scheme adopted by the utility model for solving the technical problem is as follows: A ball mill, which uses the ball mill lining plate according to any one of the above aspects. Compared with the prior art, the utility model has the following beneficial effects: 1. The ceramic is not suitable for being used as an integral lining plate, the ceramic is made into relatively small block-shaped bodies, the relatively small block-shaped bodies are arranged in the lining plate of the ball mill, the ceramic is cast and fused into a whole, and the ceramic is used as the lining plate of the ball mill, and the wear resistance of the ceramic is 10 times higher than that of the traditional lining plate material, meanwhile, the probability of rolling up the material to a high position can be greatly improved through the lifting strip on the lining plate base layer, the impact crushing efficiency is improved, the wear resistance of the material ensures the friction crushing efficiency, and the service life is greatly prolonged due to less wear.
