Product introduction
VSI vertical shaft impact crusher (sand making machine) is our crystallization of diligence and wisdom . Its integrated design we owe to the technology R&D specialists who personally go to the scene to understand the demand and opinions of equipment operators. By increasing production, reducing wear cost, prolonging maintenance cycle, thus we developed this multi-purpose crusher which has a couple ways of feeding and crushing modes, making it become the preferred device in the fields of stone integer, artificial sand, refractory, ball mill feeding, industrial construction materials processing and so on.
Product superiority
Two crushing ways of “rock on rock” and “rock on iron”.
Multiple crushing ways meet the needs of different materials crushing.
Dual Pump Design
There is only one pump working in normal use. When the value of the pressure and flow rate do not reach the set value or when the first pump fails the second will open automatically to ensure the normal operation of the host.
Hydraulic Arms
Hydraulic arm design greatly reduces maintenance costs.
Bearing Bit Thermostat
Bearing bit thermostat and pump automatic cycle ensure that the temperature inside the bearing cartridge similar to the oil in the tank to prevent the winter freeze.
Working principle
VSI crusher design is based on the principle of mutual crushing and friction in the high-speed movement materials. This type sand making equipment can not only crush stones but also the stones and gravel can be shaped by it. According to feeding method centrifugal impact crusher working form is divided into central feeding and central with cascade feeding; the crush form is divided into “rock on rock” and “rock on iron” according to material compressive strength abradability. So the VSI crusher can be divided into four kinds: “rock on rock” and “rock on iron” with central feeding “rock on rock” and “rock on iron” with central with cascade feeding. Material from the hopper falls into VSI sand crusher and will be divided into two parts. One part passed into high speed rotating wheel to be accelerated and high-speed projectile rapidly impact crushing another part of the material from points around the tray and will be impacted on the vortex branch cavity lining together. Then it will be bounced back to the top of vortex chamberand the movement direction would be changed to start moving down on the diagonal; materials emitters from the impeller form a continuous material curtain. Finally crushed material discharge from the lower discharge port.

Safety Assurance |
Double oil pumps assure enough oil supply; Switch off automatically without oil flow or oil pressure. Lower the temperature with cool water in summer raise the temperature with motor in winter. |
