SBM VSI crusher is designed by reputed German
expert of Shibang and every index of VSI crusher is in world’s leading standard.
SBM VSI crusher incorporates three crushing types and it can be operated 720
hours continuously. Nowadays, VSI crusher has replaced hammer crusher, roller
crusher, roller ball mill, etc. and become the mainstream equipment in sand
manking business.
Technological advantages:
VSI crusher incorporates three crushing styles; its feeding style incoporates
material on material, materials on iron and falling at sides. Customers can
adjust the machines according to their own demand. VSI crusher realizes multiple
functions in one machine, which is a big breakthrough in sand making field.
Excellent performance and long service time:
special light oil
lubracation systems ensures the temperature to be within 25℃;
brand new automatic protection device provides the machine with vibrating, oil filtering and warning system;
new type oil filting system ensures the bearings and other transmission system are not abraded and peolong their service time;
choice wearble materials prolong the service time of the machine by 40%. So
the cost is lowerd by more than 40%.
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.
