Pendent up-and-down-swing grinder

Abstract

The invention discloses a pendent up-and-down-swing grinder which comprises a table type operation platform, a feeding bin and a grinding driving device, wherein the feeding bin and the grinding driving device are arranged above the table type operation platform; a grinding bin passes through the table type operation platform; the side wall of the grinding bin is provided with a feeding through hole; the feeding through hole is communicated with the bottom of the feeding bin; the grinding bin is internally provided with a mill knife which is connected with a motor driving shaft; the motor driving shaft is connected with the grinding driving device; a leakage screen device is connected with the grinding bin at the end far away from the table type operation platform. The pendent up-and-down-swing grinder has the advantages of being simple to process, low in production cost, short in grinding time and low in vibration, and eliminating grinding dead corner.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a drooping up and down pulverizer. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of pulverizing in the form of high-speed impact. Using wind energy to form powder at one time, canceling the traditional screening procedure. It is mainly used in mining, building materials and other industries. [0003] According to the size of the crushed material or crushed material, the pulverizer can be divided into a coarse crusher, a medium crusher, a fine grinder, and an ultrafine grinder. [0004] There are four kinds of external forces applied to the solid during the crushing process: rolling, shearing, impact, and grinding. Rolling is mainly used for coarse and medium crushing, suitable for crushing hard mater...

AI Technical Summary

Problems solved by technology

Its mechanism is complicated, the production cost is high, the vibration is large, and the crushing time is long

After comparative analysis of the factors causing the above reasons, it is found that since most motors are placed below and the crushing chamber is set above the motor, under the action of gravity, if the grinding tool does not move close to the crushing chamber, the crushing time will be shorter. In addition, due to the loss of the grinding tool, the crushing effect can also be weakened
