This Our VSI sand Maker is also be called as vertical shaft impact crusher .machine is widely used in the fine
crushing and coarse grinding of metal and non-mental ores, cement, fireproof materials, glass materials, building
frame, artificial sand and various kinds of metallurgical residues. Vertical shaft impact crushers are suitable for
all various materials, and the finished product is cubic shape.Compared with other type crushers, it has advantages
of crushing middle and super hard and abrasive materials. Combined with the jaw crusher, it can be used for the
comprehensive recycling and utilization of various metallurgical residues.
Working Principle
The materials enter into the crusher through the feed hopper, and divided into two parts by the distributor; one part
enters into the high-speed rotating impeller through the middle of the distributor, the materials will be cast out
from three evenly-arranged interval channels at the speed of 60一75m/s; first, the materials will be shocked and
crushed with the part of materials freely fallen from around the distributor, then they will be concussed onto the
material lining in the whirl compartment, rebounded by this lining, they will be concussed onto the top of the whirl
compartment in upswept direction; then the movement direction will be altered, moving downward, and the materials
launched from the impeller channel will form the continuous material screen. By this way, the materials will be
crashed, fractionized and grinded in the whirl crushing compartment for two or many times. The crushed materials
will be discharged from the lower opening to form a closed circuit with the circular screen system. Generally, the
materials can be crushed to be below 20 meshes through three circulations.
Features
Small iron pollution; During the whole crushing process, the materials shock and crush mutually and
automatically, not direct-contact with the hardware, but crushing the materials by shock and friction with the
material lining.
Large-scale reduction of the wear part expense and maintenance work; Due to the self-lining materials in
the impeller and whirl crushing compartment.
Low power consumption; Overflow feed will not increase the power consumption and abrasion expensed for the
crusher, but it will increase the granule density in the crushing compartment to crush more grains more effectively
and improve the rate of energy utilization.
With strong ability of passing non-crushing materials; with little impact from the water content of
materials and the water content can reach to 8%.
