Grinding and screening device for stone powder processing

Abstract

The invention provides a grinding and screening device for stone powder processing. The grinding and screening device for stone powder processing comprises: a grinding machine body; a material elevator which is arranged at a discharge hole of the grinding machine body, wherein a charge hole of the material elevator is matched with the discharge hole of the grinding machine body; a box body which is arranged on one side of the grinding machine body, wherein a charge hole is formed in the top of the box body; a supporting frame which is fixedly mounted at the bottom of the box body; and a charge hopper which is fixedly installed on the top of the box body, and is matched with the charge hole. The grinding and screening device for stone powder processing has the advantages that the ground stone powder is subjected to three-stage screening so as to be used for multiple purposes, the stone powder on the screen can be conveniently pushed out of the screen, and the stone powder with too large roughness can be conveniently ground again until the use standards are met.

Description

technical field [0001] The invention relates to the technical field of stone powder processing, in particular to a grinding and screening device for stone powder processing. Background technique [0002] Stone is a building decoration material, which is widely used. The original mined stone is relatively large and irregular in shape. Before use, it needs to be cut into slabs, stones, etc. for convenience; and the surface of the stone is relatively rough, and it needs to be polished before it can be used; A large amount of stone powder will be produced in the process of stone cutting and grinding, and these stone powder can be recycled through a certain process. Among them, it will be ground into powders of different thicknesses by milling equipment, and sieved by sieving and rotary equipment for different processes and purposes. [0003] After the grinding equipment grinds the rock, the fineness of the obtained stone powder is different. It is generally difficult to sieve s...

AI Technical Summary

Problems solved by technology

[0003] After the grinding equipment grinds the rock, the fineness of the obtained stone powder is different. It is generally difficult to sieve stone powder of various finenesses during sieving, and the coarser stone powder sieved from the sieve is inconvenient to discharge, and If the stone powder is too fine and cannot meet the standard of use, it needs to be recycled manually to continue to use the grinding equipment for re-grinding. Manual recycling is troublesome and the efficiency is relatively low.
