Compared with traditional sand maker

The VSI which can also be called VSI series vertical shaft impact crusher,is an advanced and high-efficiency equipment. It is the latest researched results basing on Germany technology.Compared with traditional sand maker, it can save more energy, have higher anti-pressure strength and higher processing efficiency and the final products are even in granularity.It adopts hydraulic device so that it is easier to realize automatic production.The machine is professional in producing qualified sand and stone for highway, high-speed railway, high building, city project, hydropower dam constructions, and concrete mixing plant. It is the best choice for sand making and stone reshaping industry. is designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crusher machines may be used to reduce the size, or change the form, or to reduce the size of a solid mix of raw materials, of waste materials so they can be more easily disposed of or recycled, so that pieces of different composition can be differentiated.This sand making machine is specially designed for highway, high-speed railway, high-rise buildings, municipal, hydroelectric dam construction, concrete mixing station to provide quality sand aggregate, is the preferred equipment in the artificial sand production line. Entire Center Feeding: Materials fall into the hopper of VSI sand making machine, then get into the high speed rotating wheelie through center feeding hole. Materials are speed up rapidly in the wheelie, the speed can be dozens of times of gravity acceleration, then shoot out at high speed and hit against the materials falling free after being rebounded, then they are all impacted to the liner layer of materials to strike against each other, or to the counterattack board to be bounded oblique upward to the top of the eddy current cavity, then change their heading , deflect and move downward, then strike against the materials shot out from the impeller passage , which forms continuous material flow. So the materials are hit, rubbed and grinded for two or more times in the eddy current crushing cavity. The crushed materials are discharged from the lower outlet.
