Zenith B Series VSI Crusher is one of the most advanced impact crusher nowadays. It introduces high quality roller bearings like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit. Personlized design used in upper cap, it is easy and convenient to maintain and replace spare parts. It is our sole patent that using central feeding & central cascade feeding, which can be changed based on customers' needs.

Better quality and high efficiency:

better design of the impellers reduces the resistance of materials, highlightens passing through quantity of materials and crushing ratio, so the efficiency is raised by 30%-60% compared to traditional machines.
Hydraulic system allows automatic uncovering, which reduces labour intense and makes maitenance easier.
The mainframe adopts new techniques, which strengthens the machine structure and tenacity, and ensures stable performance. The quality of the machines is lift to a higher level.
VSI crusher employs world advanced light oil anti-leakage device. This saves the trouble of changing oil seal.

Feed at center:

After materials are fed into the hopper, they are, through a central feeding hole, thrown to the impellers, which are rotating at a high speed. Then, the material are accelerated and thrown out of impeller area. These part of materials, first, impact on the other part of materials, which are falling down, and then, they together strike on the material layers or on impact blocks. Due to rebound, they will back to top of crushing cavity and again be shot back to strick on another part of materials which are shot from the impeller flow and form a continuous material curtain. The final products will be discharged from the discharge open at the bottom.

Feed both at center and at sides:

After materials are fed into hopper, they fall down througha circular hole and are divided into two parts by the distributing mantle. One part enters the impellers, which are rotating at high apeed; the other part fall down along the mantle. The first part are accelerated at the impeller area and aare thrown out and to strike on the falling materials at sides. Then, they together strike on the material layers in whirlpool cavity and again be shot back to strick on another part of materials which are shot from the impeller flow and form a continuous material curtain. The final products will be discharged from the discharge open at the bottom.
