Ball mill

Abstract

The invention relates to the field of smashing devices, and discloses a ball mill. The ball mill comprises a supporting seat, a ball mill body, an air inlet pipe, a first feeding pipe, a discharging pipe, a discharging hopper and an air outlet pipe. A rough filtration feeding hopper is arranged at the top of the first feeding pipe in a communicating mode, and a refined filtration detection deviceis arranged on one side of the ball mill body. The refined filtration detection device comprises a shell, a rotating pipe and a screening barrel, an unqualified material recovery pipe is rotatably arranged at the bottom of the screen barrel in a communicating mode, qualified material discharging hoppers are arranged at the positions, located on the two sides of the unqualified material recovery pipe, of the bottom of the shell in a communicating mode, a power device for driving the rotating pipe to rotate is arranged at the position, located on one side of the rotating pipe, of the top of theshell, a second feeding pipe is rotatably arranged in the rotating pipe, one end of the second feeding pipe is stretched into the rotating pipe, and a material-lifting and feeding device is arranged at the end, away from the screen barrel, of a discharging opening of the discharging hopper and the second feeding pipe in a communicating mode. The ball mill can improve the insufficient grinding of materials, so that the ground materials are more uniform, and thus the product quality is ensured.

Description

technical field [0001] The present application relates to the field of crushing devices, in particular to a ball mill. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries. It can dry or wet powder various ores and other grindable materials. grind. [0003] The ball mill is one of the high-fine grinding machines widely used in industrial production. The existing ball mill mainly includes a feeding part, a rotary part, a load-bearing part, a discharging part and a transmission part. The main body of the rotary part of the ball mill is a cylinder, which is a long cylinder, and the cylinder is equipped with grinding bodies. According to different diameters and a certain proportion, it is loaded into the barrel. The materia...
