Mining machinery Sand making line 1. Large crusher capacity 2. Low consumption 3. Perfect grain shape Crusher, Mining machine Vertical Impact crusher It is widely used in crushing of metal and non-metal or cement, refractory materials, bauxite, quarts z, glass raw material, building aggregate, artificial sandy, soil and all sort of metallurgy, slag, especially for middle hardness and special hardness material. It has the most advantages than other type crusher. Vertical Impact crusher Working principle: The Vertical Impact crusher enters into crusher through feeding hopper, the material is divided into two parts by distributor, some of the material enters into high speed rotated impeller through the middle of the distributor and are fast accelerated inside the impeller, their speed can reach one hundred times acceleration of gravity, and then cast out through around flow channel of the impeller by 60--75m/s, firstly are impulsed and crushed with the material freely fallen from arounddistributor and then they are impulsed into bow wave lining layer in bow wave crushing chamber and then their moving direction is changed and are turned down towards and formed material continuous screen with materials emmited form impeller's flow ways. So, a piece of material has twice to many times probility to be impulsed, rubbed crushed and milled in the bow wave crushing chamber, the broken materials are discharged through discharge outlet at the bottom and formed into dosed route through circulating sieve system, generally three times circulation can rush the materials under 4.75mm, the smart air self-circulation in the bow wave crushing chamber elimilates dust pollution.
