Vertical-shaft impact sand making machine

Abstract

The invention relates to the field of mine equipment and particularly relates to a vertical-shaft impact sand making machine. The vertical-shaft impact sand making machine 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 is arranged on the machine frame, the feeding hopper assembly is arranged above the crushing chamber assembly, the rotor set is arranged inside the crushing chamber assembly, and the main shaft set is connected with the rotor set. According to the vertical-shaft impact sand making machine, during work, materials are stacked on a middle-part material stacking plate and a bottom material stacking plate, so that a protective layer for a crushing chamber shell body is formed, the collision and wear to the crushing chamber shell body caused by the materials are avoided, and thus a very good protecting effect on the crushing chamber shell body is exerted; the rotor set is used for standardizing the discharging of the materials sequentially through material distributing, material guiding and material throwing, so that the smooth discharging of the rotor set can be guaranteed, and the breakage rate of the sand making machine is maintained.

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. It is thrown at high speed and collides with the surrounding falling materials, and the stones are broken by the way of "rock hitting rock". However, in the existing sand making machine structure, it has the following two disadvantages: 1. The structure of the crushing chamber assembly is single, and the internal protection of the crushing chamber assembly is insufficient. The outer casing of the crushing cavity assembly is collided and worn, which seriously affects the normal operation of the equipment; 2. The structure of the rotor group of the sand making ma...

However, in the existing sand making machine structure, it has the following two disadvantages: 1. The structure of the crushing chamber assembly is single, and the internal protection of the crushing chamber assembly is insufficient. The outer casing of the crushing cavity assembly is collided and worn, which seriously affects the normal operation of the equipment; 2. 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 eventually causes the sand making machine to Reduced crushing efficiency
