Charging device for crushing of mining stones

Abstract

The invention provides a charging device for crushing of mining stones. The charging device comprises a main body and a spiral conveyer, wherein the main body comprises a feed hopper, a feed box and a discharging hopper; the outer wall of the upper side of the feed box is provided with the feed hopper; a plurality of inclined baffle plates are arranged on the inner wall of the feed hopper in an interlaced mode; the bottom of the feed hopper is communicated with the feed box; the bottom of the feed box is communicated with the discharging hopper; in the feed box, a mesh screen is aslant arranged between the feed hopper and the discharging hopper; the lower end of the mesh screen is communicated with a material return pipe; the material return pipe is communicated with the lower end of the spiral conveyer; the upper end of the spiral conveyer is communicated with a discharging pipe; and a pipe mouth of the discharging pipe is opposite to an inlet of the feed hopper. According to the charging device, minerals to be crushed are pre-crushed and screened, thereby effectively improving the crushing efficiency and reducing the damage to a crusher, simultaneously reducing diffusion of mineral sand dust and improving the operation security.

Description

technical field [0001] The invention relates to the technical field of mine beneficiation devices, in particular to a feeding device for crushing mine stones. Background technique [0002] The crusher plays a vital role in the crushing of mineral materials. However, due to the high hardness and heavy weight of the mineral materials, when the mineral materials are unloaded on the crushing mechanism, the mineral materials are in the state of free fall and The impact of the crushing mechanism will cause a large impact on the crushing mechanism, and will also generate relatively large noise and ore dust, which seriously affects the service life of the equipment and the working environment. In addition, the mineral materials have high hardness and different sizes, and the efficiency and uniformity of the crushing are low, which reduces the crushing efficiency and quality. Contents of the invention [0003] In view of the above existing problems, the present invention proposes ...

Problems solved by technology

[0002] The crusher plays a vital role in the crushing of mineral materials. However, due to the high hardness and heavy weight of the mineral materials, when the mineral materials are unloaded on the crushing mechanism, the mineral materials are in the state of free fall and The impact of the crushing mechanism will cause a greater impact on the crushing mechanism, and at the same time generate greater noise and ore dust, which seriously affects the service life of the equipment and the working environment

In addition, the mineral materials have high hardness and different sizes, and the efficiency and uniformity of the crushing are low, which reduces the crushing efficiency and quality.
