Ball mill feeding apparatus

Abstract

The invention discloses a ball mill feeding apparatus. The ball mill feeding apparatus comprises a feeding pipe, a supporting base, a feeding hopper, a sealing flange and a feeding bushing, wherein the feeding pipe is fixed on the supporting base, the front end of the feeding pipe stretches into a feeding opening of a ball mill, a returning screw is arranged in the sealing flange, the spiral direction of the returning screw is consistent with the feeding direction, one end of the sealing flange is fixed on the feeding bushing, the other end of the sealing flange is provided with an inclined anti-abrasion rubber plate, the feeding pipe is provided with angular sealing rubber, the anti-abrasion rubber plate tightly contacts the angular sealing rubber, a rotating shaft is arranged in the feeding pipe in a penetrating manner, the rotating shaft is provided with screw blades, the top of the feeding pipe is provided with the feeding hopper, the end part of the rotating shaft is provided with a reducer, one end of the reducer is connected with the rotating shaft by virtue of a coupler, and the other end of the reducer is connected with an electromotor output shaft. By adopting the ball mill feeding apparatus, abrasion to a sealing part is alleviated, the sealing effect is good, the installation is convenient, the adjustment is simple, and the blockage of the feeding pipe can be effectively prevented.

Description

technical field [0001] The invention relates to a ball mill feeding device, which belongs to the technical field of ball mills. Background technique [0002] Ball mill is the key equipment for crushing materials after being crushed. It is widely used in the production of cement, silicate products, new refractory materials, chemical fertilizers, mineral processing and glass ceramics. At present, there is relative sliding between the feed pipe and the feed port of the ball mill during production and use, and slurry leakage is common, resulting in a bad operating environment. The main cause of slurry leakage is that the rotating seal is in direct contact with the unclean surface of the stationary feeding pipe. The splashed slurry collides with the seal, which intensifies the wear of the seal, causing serious wear of the seal, and it is difficult to adjust after a small amount of wear. This sealing method leads to frequent replacement and affects work efficiency. In addition, ...

AI Technical Summary

Problems solved by technology

The splashed slurry collides with the seal, which aggravates the wear of the seal, causing serious wear of the seal, and it is difficult to adjust after a small amount of wear. This sealing method leads to frequent replacement and affects work efficiency.

In addition, when the fine sand is finely ground, because the fine sand particles are small, especially in the rainy summer, the water content of the fine sand is high, which is easy to cause blockage of the feed inlet, resulting in idling and parking of the ball mill, which affects the continuity of production and reduces Increased product output and increased production costs
