Description

A crushing device for dolomite

Technical Field

The utility model relates to the technical field of crushing equipment, in particular to a crushing device for dolomite.

Background Art

Dolomite has basic properties such as surface adsorption, pore filtering, and ion exchange between mineral layers. It has the advantages of low cost and no secondary pollution. 200 mesh dolomite can be used as a glass raw material in glass production and can be ground using a crushing device.

The existing patent announcement number CN213708103U discloses a glass crushing device, which is provided with a sealing cylinder cover, a charging cylinder and a connecting rod. When crushing, a glass plate is placed through the top of a blanking square sleeve, and the crushing plate is driven by the extension of the crushing cylinder. The glass plate can be crushed by the conical pressure block, so as to achieve preliminary crushing of the glass. After crushing, the second servo motor drives the sealing plate to rotate, so that the bottom of the blanking square sleeve is opened, and the glass fragments after preliminary crushing enter the charging cylinder. The sealing cylinder cover is further installed and locked by a buckle lock, so as to achieve the closure of the top of the charging cylinder. The rotating motor drives the fixing frame and the charging cylinder to drive horizontally to achieve horizontal rotation. While rotating horizontally, the bevel gear walks on the tooth groove, so that the connecting rod and the charging cylinder rotate horizontally. Through rotation in two directions, in cooperation with the breaker hammer, crushing is achieved.

When the above device is crushing, conical pressing blocks and breaker hammers are used to crush the glass plates. The particle size uniformity of the crushed particles still needs to be improved, and multiple processing is required. When the glass is reused, it needs to be remanufactured according to different finenesses.

In view of the above problems, a crushing device for dolomite is proposed.
