Description

Technical Field

[0001] The utility model relates to the technical field of ball mill lining plates, in particular to a circulating ball mill lining plate. Background Art

[0002] Ball mill is a kind of equipment used for grinding cement, coal, ore and other materials in cement, thermal power, mining and other industries. It has high energy consumption, accounting for 70%, 30% and 40-50% of the electricity consumption of various industries respectively. Its total electricity consumption accounts for 2% of the national power generation, and it is an important object for energy conservation and consumption reduction. The inner wall of the cylinder is protected by a liner to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, which helps to improve the grinding efficiency of the mill, increase production and reduce metal consumption. The liner is made of different materials such as rubber and metal. Rubber liner has the advantages of wear resistance, corrosion resistance, low noise, light weight, etc., and has obvious energy-saving advantages over metal liner. With the emergence of new technologies, it is increasingly widely used.

[0003] In the prior art, for example, the Chinese patent number CN205361524U, "A ball mill lining plate", includes a plate body fixed on the inner wall of the ball mill cylinder, the plate body is a hollow cylindrical structure matching the inner wall of the ball mill cylinder, and a plurality of protrusions are evenly arranged on the inner wall of the plate body, the protrusions are conical, and the tips of the protrusions face inward, and the distance between two adjacent protrusions matches the diameter of the steel balls of the ball mill. The utility model provides a ball mill lining plate, which can speed up the grinding efficiency by evenly arranging a plurality of protrusions on the inner wall of the plate body, thereby saving the energy consumed by the equipment.

[0004] A large number of existing ball mill lining plates are distributed on the inner wall of the ball mill barrel. Due to the large number of lining plates, after a long period of operation, when the lining plates are worn or broken, it is not convenient to quickly replace the lining plates, which increases the difficulty of operation for the staff and reduces the efficiency of maintenance operations.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the inner lining plate and the sliding plate of the ball mill are offset to the side of one end of the sliding rail, and then the inner lining plate of the ball mill is moved to one end. During the sliding process, one end of the limit buckle is pressed to make the spring contract, so that the sliding plate can slide into the inner side of the sliding rail synchronously. After sliding in, the limit buckle is loosened, and the other end of the limit buckle is conveniently connected to the end of the sliding rail, thereby realizing the limiting effect. When disassembly is required, it can be slid out in the opposite direction, which is beneficial to improving the fast and stable installation effect, and also convenient for rapid replacement after wear in the later stage, effectively improving the convenience of operation.
