JOYAL VSI Sand Making Machine

The JOYAL VSI Sand Making Machine is improved on the basis of Germany high technology, which is highly-efficient and superior in performance. The JOYAL VSI Crusher (sand making machine) is widely used to produce sand and stone for highway, high-speed railway, city project, hydropower dam constructions, and concrete mixing plant, and it’s also widely used in sand making and stone reshaping industry.Central feeding:Raw materials fall down into the feeding hopper, then enters the impellor through central entrance inlet, thus the material being accelerated by the high-speed impellor and being thrown out at the speed of 60-75m/s. It is crushed when hitting the impact plate, and the end products comes out from the discharging outlet. Ring feeding:Raw materials fall down into the feeding hopper, and the materials are divided into two parts by a special plate. Some materials enter the impellor through the center of the plate and the other part of materials falls down from outside of the plate. The materials thrown out earlier crush the materials down from outside, thus the materials crushed and re-crushed.
