Crusher is a relatively common equipment in the mining industry, and the types of equipment are relatively diverse, such as jaw crushers, impact crushers, cone crushers, etc., all of which have a large crushing ratio, good grain size of the finished product, and low energy consumption. The advantages of easy maintenance and other advantages have been favored by the majority of users. Here is an introduction to the vertical impact crusher. What is the difference between it and other equipment?
First of all, we first understand the working principle of the vertical impact crusher:
The material falls into the hopper, enters the rotating impeller through the feed hole and accelerates, and then shoots out from the impeller. It first collides with another part of the free-falling material after rebounding, and then impacts the vortex material lining in the vortex cavity together (stone beat stone) is first bounced to the top of the crushing cavity, and then deflected to move downward, colliding with the material emitted from the impeller runner to form a continuous material curtain, and then discharged through the lower discharge port, controlled by the screening equipment to achieve the required particle size of the finished product.
It is precisely because of the working principle of the vertical shaft impact crusher that this crusher is widely used for the fine crushing of raw materials and clinker in cement plants, and also used for dolomite, flint clay, lead-zinc ore, serpentine, high fine crushing of medium-hard materials such as slag, coal gangue, phosphate rock, etc., especially for artificial sand making of hard limestone, dolomite, granite, basalt, etc., or processing and crushing of road pavement stones.
Vertical shaft impact crushers are widely used in these industries due to their performance advantages. The particle shape of the finished product processed by the vertical shaft impact crusher is good. In addition, the vertical shaft impact crusher is suitable for crushing medium-hard and super-hard materials, and the crusher has little effect on the moisture content when processing these materials and the moisture content can reach about 8%. In terms of maintenance, this type of crusher uses the principle of hitting rocks with stones, and the impeller self-lining wear is small, and maintenance is convenient.
