VSI Series Vertical Shaft Impact Crusher
DEVICE DETAILS:
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.

ADVANTAGE:
Motor
Standard high-performance vertical motor.
Alloy wear resistant block
Alloy wear-resistant block adoptes highly wear resistant and high temperature resistant materials in important U.S. industries and thus has a longer service life.
The New Impeller Design
Optimize material flow increase production by 30%.
Optimize material flow increase production by 30%.
Height can be adjusted to control the feed volume and different proportion of materials that are vertically into the impeller and scattered around of the impeller to adjust the particle size ratio.
WORK PRINCIPLE:
Material from the hopper falls into sand crusher and will be divided into two parts by the distributor. One part falls into the high-speed rotation impeller through the middle and is accelerated rapidly within the impeller. That acceleration can be up to several hundred times the acceleration of gravity and then the materials project out from three uniform impeller flow channel at speed of 60-70 m / s; another part of the material falls freely from all around the feeder impact on the vortex branch cavity lining and then will be bounced back to the top of vortex chamber. The movement direction would be changed to start moving down on the diagonal; materials emitters from the impeller form a continuous material curtain. Thus materials will be hit rubbed and grinded twice or several times in whirl crushing cavity. Finally crushed material discharges from the lower discharge port. Throughout the crushing processmaterials impact and crush each other not in direct impact on the metal element but only shock rub and grind the lining thus prolonging mechanical life.
