Impact crusher

Working principle
The material from the hopper into the sand making machine, the distributor of the material is divided into two parts, a part of the sub feeder into the middle of the high-speed rotation of the impeller, the impeller is quickly accelerated, the acceleration of up to hundreds of times the acceleration of gravity, and then to 60-70 M / s velocity from the impeller three uniform flow ejection go out, first with the sub feeder around since the receipt of a portion of the material impact of falling broken, and then together to support the impact of vortex cavity lining materials, is lining materials rebound, oblique impact to the vortex chamber at the top, it changes its direction of motion, partial steering motion, is emitted from the impeller the material to form a continuous material curtain. Such a material in the vortex crushing chamber by two or more times the probability of impact, friction and grinding fragmentation. The broken material is discharged from the lower discharge port. In the whole process of crushing material by mutual impact crushing, not in direct contact with the metal components, but with material lining layer of impact, friction and grinding, which reducespollutionangle, extend thetimeofmechanical wear. The inner flow of the vortex chamber is self circulation, which eliminates the dust pollution.
Impact crusher of the utility model adopts rhombus combined impact block (jet head) instead of the overall shape of the hammer and the combined impact of the original square block. Impact block alloy "hard but not brittle, tough and strong", and high temperature resistance. The impact block directly imported high alloy forging, strength and toughness and wear resistance, in the domestic leading level, greatly improve work efficiency and service life of high manganese steel increased by 3 - 5 times, improve the production yield and quality.
