Material crushing device

Abstract

The invention discloses a material crushing device. The material crushing device is used for enabling a crushing ball to be pulled up by utilizing the lever principle, due to the fact that the crushing ball is an elastic material after being released, under the action of the gravitational potential energy, the crushing ball can be used for crushing materials on the material placing tray up and down, the potential energy is large due to the fact that the crushing ball can move up and down on the material placing tray, the compression force of the materials is large, the compression force of thematerials is small, the potential energy of the crushing ball is reduced, the compression effect of the material is reduced, the size of the compression force of the crushing ball can be changed along with the degree of material crushing, the magnetic field generated by the electrified coil attracts the magnet, the pulling wire is pulled to enable the crushing ball to return to the highest pointwhen the crushing ball loses potential energy, the electromagnetic energy is utilized to enable the crushing ball to obtain potential energy for compression, and other mechanical power devices do notneed to be additionally arranged.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to a material crushing device. Background technique [0002] The crushing device is a machine that crushes large-sized fixed raw materials to the required size. The crushing device is composed of coarse crushing, fine crushing, wind conveying and other devices. The external forces applied to the solid during the crushing process include shearing, impact, rolling, and grinding. There are four kinds; the impact is mainly used in the crushing operation; the rolling is mainly used in the high-fineness crushing operation; the crushing devices in the prior art are mostly matched with the screening device; the crushing devices are mostly rotating rollers or crushing balls, Use the driving device to drive the crushing ball to hit and crush the material; or use the driving device to drive the rotating rollers that rotate with each other to grind the material; It is always at the same stren...
