Wear-resistant lining plate for large self-grinding machine / large semi-self-grinding machine

Abstract

The invention discloses a wear-resistant lining plate for a large self-grinding machine / a large semi-self-grinding machine. The wear-resistant lining plate is characterized in that the bottom platesof a feeding end inner ring lining plate body, a feeding end middle ring lining plate body and a feeding end outer ring lining plate body of the wear-resistant lining plate are provided with first lifting strips which are increased in height correspondingly, and are provided with long strip bosses for increasing the wear resistance of the bottom plates correspondingly; a feeding end barrel liningplate body, a middle section barrel lining plate body and a discharging end barrel lining plate body are provided with second lifting strips with the sections of asymmetric structures; an outer ring ore pulp lifter is provided with large arc-shaped third lifting strips, long bolts and short bolts; a grid plate is provided with large arc-shaped fourth lifting strips, and an inner ring ore pulp lifter is provided with fifth long lifting strips and sixth short lifting strips which are arranged at intervals; and a discharging device is of an integral structure and is provided with seventh short lifting strips. According to the wear-resistant lining plate, the problem that in the prior art, the service life of a feeding end lining plate body is relatively low, the discharging efficiency of a grinding machine is low and the number of the lining plates is too large are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of lining boards of large autogenous mills / semi-autogenous mills, and in particular relates to a wear-resistant lining board for large autogenous mills / semi-autogenous mills. Background technique [0002] The mill liner is used to protect the barrel of the mill from the direct impact and friction of the grinding body and the material, and at the same time lift the material and the grinding body so that it has a certain movement form inside the mill and strengthens the grinding body. The key parts of the mill for the crushing and grinding of materials. With the improvement of mine beneficiation technology in our country, the development trend of large-scale mining mills, and the increase in market demand and expectations for lining boards have intensified the market competition for mining mill lining boards. The service life and grinding efficiency put forward higher requirements. The optimization of the li...

Problems solved by technology

[0004] In order to solve the above problems, the object of the present invention is to provide a wear-resistant lining plate for large autogenous mill / semi-autogenous mill with simple structure, reasonable design, convenient and efficient use, which can effectively solve the problem of the current autogenous mill / semi-autogenous mill. The life of the liner at the feed end of the mill liner is low, the discharge efficiency of the mill is low, the number of liners is too large, the material of the liner of the cylinder is wasted, the bolts of the liner are loose and broken, the discharge channel is too narrow and the discharge channel is too narrow. serious wear and tear
