Vertical Shaft Impact Crusher

Abstract

The invention relates to the field of mine equipment and particularly relates to a vertical-shaft impact crusher. The vertical-shaft impact crusher comprises a machine frame, a crushing chamber assembly, a feeding hopper assembly, a rotor set and a main shaft set, wherein the crushing chamber assembly and the feeding hopper assembly are arranged on the machine frame, the rotor set is arranged inside the crushing chamber assembly, and the main shaft set is connected with the rotor set. The vertical-shaft impact crusher is stable and firm in structure and high in crushing efficiency.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a vertical shaft impact crusher. 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 shortcomings: 1. The motor frame is fixed and cannot be adjusted, so that the distance between the drive motor installation station and the main shaft group cannot be adjusted, resulting in inconvenience in the installation of the conveyor belt, and the conveyor belt is slightly After l...

AI Technical Summary

Problems solved by technology

However, the existing sand making machines have the following shortcomings: 1. The motor frame is fixed and cannot be adjusted, so that the distance between the drive motor installation station and the main shaft group cannot be adjusted, resulting in inconvenience in the installation of the conveyor belt, and the conveyor belt is slightly After loosening, it cannot continue to be used; 2. The structure of the main shaft frame is single and the strength is insufficient, which is prone to cracks and affects safe production; 3. The structure of the crushing chamber assembly is single, and the internal protection of the crushing chamber assembly is insufficient. In the middle, the stone will collide and wear the outer casing of the crushing cavity assembly, which seriously affects the normal operation of the equipment; 4. The feed hopper assembly cannot adjust the flow of the material while dividing the material, so the sand making machine is in the During the test machine, the flow rate of the throwing and blanking materials was limited, and the flow rate of the throwing and blanking materials could not be adjusted during daily use, which could not meet different crushing needs; 5. The spindle group had insufficient spindle stability and bearing sealing effect Unfavorable phenomenon, prone to bearing damage, oil leakage and dust inclusion; 6. The structure of the rotor group is complicated, which leads to the unsmooth discharge of the rotor group, which affects the throwing of materials, and ultimately reduces the crushing efficiency of the sand making machine.
