A material crushing device

Abstract

The present invention is a kind of material crushing device, which utilizes the principle of leverage to make the crushing balls be pulled up and fall from a high place after being released. Since the crushing balls are made of elastic materials, under the action of gravitational potential energy, the crushing balls can be placed up and down on the material placement tray. The bullet crushes the material, and because of the high potential energy at the beginning, the compression force on the material is large. As the material is compressed smaller, the potential energy of the crushing ball becomes smaller, and the compression effect on the material becomes smaller. The degree of crushing changes the compression force of the crushing ball, and the magnetic field generated by the energized coil attracts the magnet. When the crushing ball loses potential energy, the pull wire is pulled to return to the highest point, that is, the electromagnetic energy is used to make the crushing ball gain potential energy. For compression, no additional mechanical power devices are required.

Description

Technical field [0001] The present invention relates to the field of pulverization, and is specifically a material pulverization device. Background technique [0002] The pulverizer is a mechanical mechanical mechanical, pulverizing the large-sized fixed raw material to the required size, and the pulverization device consists of coarse crushed, fine broken, wind conveyance and other devices. It is applied to the solid external force to be cut, impact, rolling, and grinding during the pulverization process. Four; in which the impact is mainly used in pulverization operations; the rolling is mainly used in high-frequency pulverization operations; the pulverization apparatus in the prior art is multiflorsed with the screening device; the pulverizer is more rotating roller shaft or pulverized ball, Drive the pulverizer with a drive device to stringer the material; or a rotating roller that rotates with each other with a drive device to ground the material; however, the existing pulve...

Problems solved by technology

[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 types; 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 strength, and the crushing strength of the crushing device cannot be slowed down or increased according to the degree of material crushing, and the driving device is always at the same frequency, resulting in waste of power
