Product Introduction：

VSI sand making machine is a model of the combination of mature fine crushing technology and mechanical manufacturing. Its special rotor structure design, wear-resistant material technology, crushing speed optimization and hydraulic design can provide high-quality sand and gravel aggregates for highways, high-speed railways, high-rise buildings, municipal construction, hydropower dam construction, and concrete mixing plants. It is an ideal equipment in the field of artificial sand making and stone shaping.

 Applications: 

Sand and gravel yard , concrete sand making , dry mortar , machine-made sand , power plant desulfurization , quartz sand, etc.

 Working Principle：

Full center feeding: the material falls into the feed hopper of the sand making machine, enters the high-speed rotating impeller through the center feed hole, is rapidly accelerated in the impeller, and its acceleration can reach dozens of times the acceleration of gravity, and then is thrown out of the impeller at high speed, first collides with another part of the material that falls freely after rebounding, and then impacts the material lining (stone hitting stone) or the impact block (stone hitting iron), is rebounded and impacted obliquely upward to the top of the vortex cavity, and then changes its direction of movement, deflects downward, and collides with the material emitted from the impeller flow channel to form a continuous material curtain. In this way, a piece of material is subjected to two or more collisions, friction and grinding and crushing in the vortex crushing cavity, and the crushed material is discharged from the lower discharge port.

Central feeding accompanied by annular waterfall feeding: the material falls into the feed hopper of the sand making machine, falls through the annular hole, and is divided into two streams by the dividing plate. One stream enters the high-speed rotating impeller through the dividing plate, and the other stream falls from the surrounding of the dividing plate. The material entering the impeller is rapidly accelerated in the impeller, and its acceleration can reach dozens of times the acceleration of gravity. Then it is thrown out of the impeller at high speed, first impacted and crushed with another part of the material that falls freely around the distributor, and then impacted on the eddy lining in the eddy current chamber together, rebounded by the material lining, and impacted obliquely upward to the top of the eddy current chamber, and then changed its direction of movement, deflected and moved downward, and collided with the material emitted from the impeller flow channel to form a continuous material curtain. In this way, a piece of material is subjecte

Performance Advantages：

1.A variety of feeding methods can be switched

It can conveniently realize the conversion between the two feeding modes of complete center feeding and center feeding accompanied by waterfall feeding, and it can also conveniently realize the conversion between "stone hitting stone" and "stone hitting iron". One machine can be used for multiple purposes to meet different user requirements such as stone crushing and shaping.

2.Fineness modulus can be adjusted The fineness modulus is adjustable and controllable, the product has excellent particle shape, is cubic, has low needle-like content, has high bulk density, uniform grading, and low iron pollution. It is suitable for aggregate shaping, artificial sand making and high-grade highway aggregate production

3.Automatic detection is safe and reliable Equipped with excessive vibration display and alarm device, if the equipment malfunctions, it can issue a warning and stop the equipment from working, thus achieving the purpose of protecting the equipment.

4.Green and less pollution The unique air circulation system greatly reduces the exhaust air volume, reduces dust pollution, and is beneficial to environmental protection. In addition, the reserved position of the crusher is also suitable for installing dust removal equipment of various specifications.
