The vertical shaft impact crusher is also called a sand making machine. It is a new type of crushing and sand making equipment. It has a simple structural design and intelligent operation. The material self-lining in the impeller and vortex crushing chamber greatly reduces the cost of wear parts and maintenance workload. The deep cavity impeller increases the throughput by 30%, has high work efficiency, and is widely used. It is widely used in the medium and fine crushing of various hard and brittle materials such as rocks, quartz stones, river pebbles, and coal gangue. It is particularly suitable for construction sand and road sand.
The sand making machine is composed of the feed hopper, distributor, vortex crushing chamber, impeller, main shaft, pulley, base, transmission device, lubrication system, etc.
The Features of CI Impact Crusher :
1.Through the optimized design of the deep cavity rotor, the material throughput is increased by about 30%.
2.The new impeller design of the sand making machine optimizes the material flow, with an capacity of up to 650 tons/hour.
3. The machine has fine crushing and coarse grinding functions. The product is cubic, with good particle size and very low flake content.
4. The sand making machine is green and environmentally friendly during operation.
5.Thin oil lubrication system and automatic maintenance. Under the same capacity, the power consumption can be reduced by 10-40%.
