Four-rotor vertical shaft impact crusher for mining

Abstract

The invention discloses a four-rotor vertical shaft impact crusher for mining. The four-rotor vertical shaft impact crusher comprises a bottom plate, a crushing cavity, rotor sets, a feeding hopper and a fixed sleeve block; driving motors are installed at the two sides of the top end of the bottom plate correspondingly, the crushing cavity is fixedly connected to the middle position of the top end of the bottom plate, and material baffles are fixedly connected to the two sides of the interior of the crushing cavity correspondingly; and the rotor sets are movably connected to the two sides of the bottom end in the crushing cavity, and the feeding hopper is fixedly connected to the top end of the cover plate. By means of the four-rotor vertical shaft impact crusher, the four rotor sets are arranged in the crushing cavity, materials enter the crushing cavity through the feeding hopper, the driving motors can drive the rotor sets to rotate, and the entering materials can be thrown out at a high speed; due to the fact that the four rotor sets are arranged in the crushing cavity, the materials thrown out by the rotor sets in pairs collide with one another, and the crushing strength is improved; and meanwhile, as the four rotor sets hedge the materials in pairs , the hedging area of the materials is increased, the collision rate of the materials is improved, and the crushing strength and the crushing rate of the materials are greatly improved.

Description

technical field [0001] The invention relates to the technical field of vertical shaft impact crushers, in particular to a four-rotor vertical shaft impact crusher for mining. Background technique [0002] Vertical shaft impact crusher, also known as sand making machine, is a high-efficiency crushing equipment with domestic and international advanced level developed in combination with the actual situation of domestic sand production. It is widely used in various rocks, abrasives, iron ore There are still many problems in the use of existing vertical shaft impact crushers for medium and fine crushing of various hard and brittle materials such as stones and concrete aggregates. The specific problems are as follows: [0003] 1. The existing vertical shaft impact crusher is a single-rotor crushing mechanism during use, and it is difficult to increase the impact power of materials, so it is difficult to crush materials with higher hardness; [0004] 2. The existing vertical shaf...
