Description

Novel crusher

Technical Field

The utility model relates to a mining machinery, in particular to novel breaker.

Background

The crusher for mining industry is widely applied to various departments such as mines, smelting, building materials, highways, railways, water conservancy, chemical industry and the like. Mainly refers to a crushing machine with the particle size of more than three millimeters accounting for more than 50 percent of the total discharge amount in the discharge. At present, the main crushers in the market are impact crushers, hammer crushers and the like.

The impact crusher has the advantages of simple structure, large crushing ratio, low energy consumption, high yield, light weight, cubic finished product after crushing and the like, and is widely applied to the industries of various ore crushing, railways, highways, energy sources, cement, chemical industry, buildings and the like.

The impact crusher is a machine which utilizes the high-speed impact of a plate hammer and the rebound action of impact plates to lead materials to be repeatedly impacted and crushed, the plate hammer is fixedly arranged on a rotor rotating at high speed, and a plurality of impact plates are arranged along a crushing cavity according to different angles.

When the material enters the action zone of the plate hammer, the material is firstly impacted by the plate hammer for the first time to be crushed for the first time, and simultaneously obtains kinetic energy to impact the impact plate at a high speed. The material is collided with the impact plate and crushed again, and then rebounded to the action area of the plate hammer to be impacted by the plate hammer again. The above steps are repeated until the mixture is crushed into a desired particle size and discharged outside the machine.

The impact crusher has a larger crushing ratio than the hammer crusher, and can more fully utilize the high-speed impact energy of the entire rotor. However, the plate hammer is very easy to wear, so that the plate hammer needs to be frequently replaced in the existing impact crusher, and the shell of the existing impact crusher is a whole, so that the replacement process of the plate hammer and the replacement process of the internal parts of the shell are complex, the replacement time is long, and the production efficiency is influenced.
