How does the Sand Making Machine work? by sunshine
Working Principle of Sand Making Machines:
The material enters into sand making machine 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 are cast out through around flow channel of the impeller by 70-75/s, firstly are impulsed and crushed with materials freely fallen from around distributor and then they are implused into bow wave lining layer in bow wave crushing chamber and rebounded by material lining layer and up to the top of the bow wave crushing chamber and then their moving direction is changed and are turned down towards and formed material continuous screen with materials emitted form impeller's flow ways. So, a piece of material has twice to many times probability to be implused, rubbed crushed and milled in the bow wave crushing chamber, the broken materials are discharged through discharge outlet at the bottom and formed into closed route through circulating sieve system, generally three times circulation can crush the materials under 4.75mm, the smart air self circulation in the bow wave crushing chamber eliminates dust pollution please note that: the power and wear cost of the machine do not need to be increased because of the overflow feeding; and the overflow feeding increases the material density in the crushing chamber, making the crush work more efficient, and improving the energy use rate.
Working Characteristics of Sand Making Machines:
A: Simple structure, low cost
B: High efficiency and energy saving, high crushing efficiency
C: Has thinning and mining functions
D: Can crush middle and special hardness materials
E: The end products with cube shape
F: Low work noise and less dust pollution
G: Easy for operation, maintenance and installation.
Vertical Shaft Impact Crusher (Sand Making Machine) is widely used in All Kinds of mineral, cement, corhart, bauxite chmotte, carborundum grain, glass raw material, machine made construction sand, stone stock and all kinds of metallurgy slag, especially carborundum, sintered bauxite, magnesite, and so on material with features of very hard and anticorrosion. And Sand Making Machine is more productive than other kind of crushers.
PCL VSI Crusher Working Principle
Stone less than 50mm enters sand making machine though conveyor belt. Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times, finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported to sand washing machine, however overlarge material will go back to sand maker to be refreshed. Output sizes can be made according to customers requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
