A vertical shaft impact sand making machine

Abstract

The invention relates to the field of mine equipment, in particular to a vertical shaft impact type sand maker. The vertical shaft impact type sand maker comprises a stander, a crushing cavity assembly arranged on the stander, a feeding hopper assembly arranged above the crushing cavity assembly, a rotor group arranged in the crushing cavity assembly, and a main shaft group connected with the rotor group. The crushing cavity assembly of the vertical shaft impact type sand maker is novel in structure and good in protection effect; the feeding hopper assembly can adjust flow of a material and can meet different damage requirements; the rotor group realizes smooth material discharging.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a vertical shaft impact sand making machine. Background technique [0002] In the field of mining equipment, the vertical shaft impact crusher is also known as the sand making machine. Its working principle is to divide the material into the throwing material in the middle and the blanking material in the surrounding area through the feeding hopper. Inside the cavity assembly, the throwing material in the middle is thrown out at high speed and collides with the surrounding falling material, and the stone is broken by the way of "rock hitting rock". However, the existing sand making machines have the following three disadvantages: 1. The structure of the crushing chamber assembly of the existing sand making machine is single, and the internal protection of the crushing chamber assembly is insufficient. The impact and wear on the outer casing of the crushing chamber assembly will s...

Problems solved by technology

However, the existing sand making machines have the following three disadvantages: 1. The structure of the crushing chamber assembly of the existing sand making machine is single, and the internal protection of the crushing chamber assembly is insufficient. Collision and wear on the outer casing of the crushing cavity assembly seriously affect the normal operation of the equipment

2. The feeding hopper assembly of the existing sand making machine cannot adjust the flow of materials while dividing the materials. Therefore, the sand making machine limits the flow of throwing and blanking materials during the test machine, which cannot be used in daily use. Adjust the flow rate of throwing and blanking, which cannot meet different crushing needs

3. The structure of the rotor group of the sand making machine is complicated, which leads to the unsmooth discharge of the rotor group, which affects the throwing of materials, and finally leads to the reduction of the crushing efficiency of the sand making machine
