Crushing device for mine

Abstract

The invention discloses a crushing device for a mine. The crushing device comprises a material feeding conveyor belt and a crushing barrel; the outer side of the conveyor belt is provided with a heating channel, the heating channel is internally provided with a plurality of heating blocks, the left upper position of the conveyor belt is provided with a material adding hopper, and the right lower side of the conveyor belt is provided with the crushing barrel; the upper end of the crushing barrel is fixedly provided with a feeding hopper, a water spraying disc is arranged above the feeding hopper, the lower end face of the water spraying disc is uniformly provided with water spraying openings, the crushing barrel is internally provided with a crushing grid, the position, below the crushing grid, of the crushing barrel is internally provided with a material collection hopper, and the position, below the material collection hopper, of the crushing barrel is internally provided with a fixed crushing gear and a movable crushing gear; and the end of a fixed rotating shaft of the fixed crushing gear is in transmission connection with a crushing motor through a belt, and the crushing motor is fixed into an installation box on the left side of the crushing barrel. The crushing device is simple and reasonable in structure, stone crushing difficulty is lowered through the principle of expansion and contraction of objects, and the service life of the device is prolonged; and meanwhile, recycled utilization of water resources is achieved through the device, and the role of saving water is played.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a crushing device for mines. Background technique [0002] Mining machinery is directly used for mineral mining and enrichment and other operations. Including mining machinery and beneficiation machinery. The working principle and structure of prospecting machinery are mostly the same or similar to the mining machinery used to mine similar minerals. In a broad sense, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, fans and drainage machinery are also used in mine operations. [0003] The mining machinery industry is one of the important basic industries that provide equipment for the mining and processing of solid raw materials, materials and fuels. It serves important basic industrial sectors such as black and non-ferrous metallurgy mining machinery engineering drawings, coal, building materials, chemicals...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing mine pulverizers use mechanical pulverization, which mostly depends on the performance of mechanical parts, which will cause serious wear and tear of mechanical parts, thereby reducing the service life of the device
