DVSI High Efficiency Vertical Shaft Impact Crusher
DVSI sand making machine is also a vertical shaft impact sand making machine. The structure of the sand making machine consists of a hopper, a distributor, a vortex crushing cavity, an impeller, a main shaft assembly, a base, a transmission device, and a lubrication system. The crushing principle is "stone-on-rock" and "stone-on-iron", and multiple feeding methods are available. In addition, the sand making machine is made of high-quality wear-resistant materials. The entire equipment has obvious advantages in crushing minerals and is currently commonly used in sand production lines The main sand making equipment.
It is widely used in sand and gravel yard, mixing plant, dry powder mortar, quartz sand, construction waste crushing and other industries, providing high-quality sand and gravel aggregate for highway, railway, construction, municipal administration, hydropower dam construction, concrete mixing station.
Its working principle one is to drop the stone into the hopper of the sand making machine, enter the high-speed rotating spinner through the central feed hole, and be rapidly accelerated in the spinner. Its acceleration can reach tens of times the acceleration of gravity, and then the spin Throwing from the wheel, first hits another part of the material that is free-falling after the rebound, and then impacts on the material lining or counter-attack block together, and is impacted diagonally upwards to the top of the vortex cavity by the rebound, and then changes its direction of movement and deflects downward It moves and collides with the material emitted from the impeller runner to form a continuous material curtain. In this way, a piece of material is subjected to two or more chances of impact, friction and grinding and crushing in the vortex crushing cavity, and the crushed material is discharged from the lower discharge port.
The second is that the material falls into the hopper of the vsi sand making machine, and falls through the annular hole, and is divided into two strands by the dividing plate. One strand enters the high-speed spinning wheel through the dividing plate, and the other falls from around the dividing plate. . 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 thrown from the throwing wheel at a high speed. First, it is impacted and broken by another part of the free falling material around the distributor. Impact on the vortex liner in the vortex chamber together, bounced by the material liner, impact diagonally upwards to the top of the vortex chamber, change its direction of movement, deflect to move downward, and form a continuous collision with the material emitted from the impeller channel The material screen. In this way, a piece of material is subjected to two or more chances of impact, friction and grinding and crushing in the vortex crushing cavity, and the crushed material is discharged from the lower discharge port.
1. Advantages of finished products. The big advantage of this sand making equipment is the shaping effect on various ores. The finished sand and gravel material has beautiful grain shape, high gradation, fewer needles, and mostly three-dimensional, which can be used in various fields. , Especially in the field of construction, is welcomed by downstream users.
2. Production advantages. On the one hand, each part of the equipment adopts new design and material, which is not only wear-resistant but also more convenient to use with the whole machine; on the other hand, the equipment has good energy-saving effect. The vsi sand making machine saves 50%-60% energy than traditional sand making machines. The production capacity is large, and the granularity of the finished product can be combined and classified according to the different needs of users, which can meet the different needs of users.
3. Investment advantages. On the one hand, the investment cost of the vsi sand making machine is relatively low. Compared with other equipment, the equipment not only has high performance, but also has wear-resistant parts, and the size of the finished product is adjustable, so the cost is low; on the other hand, the capital recovery is fast, which It is also the quick capital recovery brought by the advantages of finished products, so it is conducive to investment and the investment prospects are broad.
4. Environmental protection advantages. The equipment not only saves energy in the sand and gravel aggregate production line, but also installs its own dust removal device, which can reduce dust pollution and has significant environmental protection advantages.
