What are the characteristics of vertical shaft impact crusher

Among the many crushers, some crushers can be seen everywhere, such as jaw crusher, impact crusher and so on.

But some crushers may be rare. Usually we call it a sand making machine, but it actually refers to a vertical shaft impact crusher, referred to as an impact sand making machine, which is an upgraded high-end crusher equipment.

Due to its high crushing rate, small grain size, small wear, good sealing, easy maintenance and other outstanding advantages, it is favored by the majority of users.
Before understanding the vertical impact crusher, let's briefly introduce its working principle.

The material falls into the feeding hopper, enters the rotating impeller through the feeding hole for acceleration, and is then ejected from the impeller. It collides with another part of the material that is free-falling after the rebound, and then hits the vortex material lining (stone) in the vortex chamber together. It * rebounds to the * of the crushing chamber, and then moves down, it collides with the material discharged from the impeller channel to form a continuous material curtain, and then discharges it through the lower discharge port. The particle size of the finished product is controlled by screening equipment.

It is precisely because of this working principle that vertical shaft impact crushers are widely used in the fine crushing of raw and clinker in cement plants. It can also be used for finely crushing dolomite, coke stone, lead-zinc ore, serpentine, blast furnace slag, coal stone, phosphate rock and other medium hardness materials, especially for hard limestone, dolomite, granite basalt and other artificial Sand or road pavement stone processing and crushing. Vertical shaft impact crushers are widely used in these industries due to their * advantages. The finished product processed by the vertical shaft impact crusher has a good particle shape. In addition, the vertical shaft impact crusher is suitable for crushing medium-hard and extra-hard materials. At the same time, when processing these materials, the impact of the crusher on the moisture is very small, which can reach about 8%. In terms of maintenance, the crusher adopts the stone principle, the impeller self-lining wears less, and the maintenance is more convenient.
