  • Feed particle size: 35-50mm
  • capacity: 60-650t/h

DVSI High Efficiency Vertical Shaft Impact Crusher Introduction:

1.The DVSI High Efficiency Vertical Shaft Impact Crusher has very good product shaping characteristics, while incurring minimal wear rates, and less power consumption than other machines. 2.The machines come with an oil lubrication system and a hydraulic opening cover device to gain access to the crushing cavity for repairs or replacement of parts as required.

Case Sample:

When processing materials with a compressive strength of less than 100MPa, the maximum feed is 1300mm and the discharge is 300mm, instead of jaw crushing equipment, gyratory crushing equipment and other coarse crushing equipment as the primary crushing equipment. When processing materials with compressive strength greater than 150MPa, the maximum feed can reach 400mm, which is used for secondary crushing operations

DVSI High Efficiency Vertical Shaft Impact Crusher Performance

The material enters the crusher from the feed hopper, and the material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. Its acceleration can reach hundreds of times the acceleration of gravity. It is ejected from the three evenly distributed flow channels of the impeller at a speed of 60-70 m/s.

Firstly, a part of the material that has fallen from the surrounding area of ​​the distributor is impacted and crushed, and then impacted together on the material lining in the vortex cavity, rebounded by the material lining, impacted diagonally upwards to the top of the vortex cavity, and then changed its direction of movement. , It deflects and moves downward, and the material emitted from the impeller runner forms a continuous material curtain. Such a piece of material is subjected to two or even multiple chance impacts, frictions and grinding and crushing effects in the vortex crushing cavity. The crushed materials are discharged from the lower discharge port. It forms a closed circuit with the circulating screening system. Generally, the material can be crushed into less than 20 meshes after three cycles. During the whole crushing process, the materials will impact and crush by themselves, instead of directly contacting the metal elements, but will impact and friction with the material lining to crush, which reduces corner pollution and prolongs mechanical wear time. The ingenious air flow self-circulation inside the vortex cavity eliminates dust pollution.

DVSI High Efficiency Vertical Shaft Impact Crusher Working Principle

The VSI sand making machine uses advanced selective crushing and cleavage crushing principles to directly apply sufficient kinetic energy to the material, and convert the kinetic energy into the crushing energy required to overcome the material through impact. The material basically breaks along its natural texture surface and cleavage surface, with good grain shape and low self-consumption. This machine can realize the conversion of two working principles: "stone hitting stone" and "stone hitting iron".

Feeding: the material falls into the hopper, enters the high-speed rotating spinner through the feed hole, is rapidly accelerated in the spinner, and its acceleration can reach tens of times the acceleration of gravity, and then shoots out of the spinner at high speed, first and after rebound Another part of the free-falling material impacts, and then impacts the material lining (stone hitting stone) or counter-attack block (stone hitting iron) together, and is impacted diagonally upwards to the top of the vortex cavity by the rebound, and then changes its direction of movement, deflecting to move downward , And collide with the material emitted from the impeller runner to form a continuous material curtain. In this way, a piece of material in the vortex crushing chamber is subjected to two times of chance impact, friction and grinding and crushing. The crushed materials are discharged from the lower discharge port.

Feeding is accompanied by a ring-shaped waterfall: the material falls into the hopper, falls through the ring hole, and is divided into two parts by the dividing plate. One part enters the high-speed rotating spinner through the dividing plate, and the other part starts from the dividing plate. Falling around the disk. The material entering the throwing wheel is rapidly accelerated in the throwing wheel, and its acceleration can reach tens of times the acceleration of gravity, and then it is shot from the throwing wheel at high speed. First, it is crushed by another part of the free falling material around the distributor, and then impacted together. On the vortex lining in the vortex cavity, it is rebounded by the material lining, impacts diagonally upwards to the top of the vortex cavity, changes its direction of motion, deflects to move downwards, and collides with the material ejected from the impeller runner to form a continuous material screen. In this way, a piece of material in the vortex crushing cavity receives two times of probability of impact, friction and grinding and crushing. The crushed materials are discharged from the lower discharge port.
