VSI sand making machine

The material falls into the feed hopper of the sand making machine, enters the high speed rotating shaking wheel through the central feeding hole, is rapidly accelerated in the shaking wheel, its acceleration can reach tens of times the acceleration of gravity, then thrown out from the shaking wheel at high speed, firstly, it impacts with another part of the material falling freely after rebounding, and then impacts together with the material lining layer (stone hitting stone) or counterattack block (stone hitting iron), and is rebounded to impact upward to the vortex cavity. The material is rebounded upwards to the top of the vortex cavity, and changes its direction of movement, deflecting downwards, and then striking the material from the impeller runner to form a continuous material curtain. In this way, a piece of material in the vortex crushing cavity by two to several times the rate of impact, friction and grinding crushing action, the crushed material by the lower discharge port discharge. The central feed is accompanied by a ring-shaped waterfall feed: the material falls into the feed hopper of the sand making machine and, after falling through the ring-shaped hole, is divided by the dividing plate into two strands of material, one entering the high speed rotating dumping wheel through the dividing plate and the other falling from around the dividing plate. The material entering the dumping wheel is rapidly accelerated in the dumping wheel, its acceleration can reach tens of times the acceleration of gravity, and then thrown out from the dumping wheel at high speed, first with another part of the material falling freely around the distributor to impact and break, and then together with the impact to the vortex lining layer in the vortex cavity, the material lining layer bounces back, impacting upward to the top of the vortex cavity, and change its direction of movement, deflecting downward movement, and from the impeller flow channel The material from the impeller runner is then deflected downwards to form a continuous material curtain. In this way, a piece of material in the vortex crushing cavity by two to several times the rate of impact, friction and grinding crushing action, the crushed material by the lower discharge port.

Multiple feeding methods can be converted： The machine can be easily converted between two feeding methods: complete central feeding and central feeding with cascade feeding, as well as between "stone hitting stone" and "stone hitting iron", making it multi-purpose to suit different user requirements such as stone crushing and shaping. Fineness modulus can be adjusted and controlled： The product has excellent grain shape, cubic shape, low flake content, high bulk density, uniform gradation and low iron contamination, suitable for aggregate shaping, artificial sand making and high grade highway aggregate production. Automatic detection for safety and reliability： Equipped with an over-vibration display and alarm device, if the equipment is in bad operation, a warning can be issued to stop the equipment, to protect the purpose of the equipment. Green and less polluting： The unique air circulation system greatly reduces the amount of external air exhaust, reducing dust pollution and contributing to environmental protection. In addition, the reserved position of the crusher is suitable for the installation of a wide range of dust removal equipment.
