Impact Sand use an editor, river gravel, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, the artificial sand stone chips. 2, construction aggregate, highway road fabric, cushion material, asphalt concrete and cement concrete aggregate production. 3, water conservancy and hydropower engineering, highway, highway, railway, passenger railway, bridges, airport runways, municipal engineering, high-rise buildings and stone shaping sand production. 4, the mining sector front crushing grinding process, building materials, metallurgy, chemical, mining, refractories, cement, abrasive material crushing and other industries. Sand structures edited by hopper, feeder points, seven parts eddy crushing chamber, impeller body, spindle assembly, base, gear and motors and other components. Hopper feed hopper structure for an inverted bevel (or cylinder), the inlet wear ring settings, from the incoming feeding equipment through to the hopper into the crusher. Sub-feeder sub-feeder is installed in the upper whirl crushing chamber, is the role of sub-feeder from hopper triage incoming third-generation sand making machine, so that part of the material directly into the feeding tube through the center of the impeller is gradually accelerated to high speed projectile out, so that another part of the material from the center of the outside of the feed tube into the outer side of the bypass whirl crushing cavity of the impeller, is out of the high-speed projectile from the impeller material impact crusher, without increasing power consumption, increasing production capacity, improve crushing efficiency. Eddy crushing chamber whirl crushing chamber shape for the structure, the annular space under the two cylinders composed eddy broken impeller rotating at high speed in the cavity, whirl crushing cavity can reside materials, forming materials lining, material crushing process takes place in whirl crushing cavity, by the crushing effect lining material whirl broken wall separated, so crushing effect solely between materials, played the role of wearable self lining. Observation hole is observed emission impeller wear and eddy mouth wearable pieces moving crushing chamber liner wear Sand top manufacturers, holes must be sealed off to observe strict crusher work. Sub-feeder fixed in the upper cylindrical section whirl crushing chamber. High-speed rotation of the impeller flow in eddy crushing cavity through the feeder, the formation of an internal impeller from the circulation system. Waterfall falling into the material feed size is larger than when the second impeller feed size, they need to feed from two feed ports respectively. Ore hopper into the river gravel crusher, respectively, through the sub-feeder feeding tube into the center of the impeller, when the materials into high-speed rotation of the impeller, the impeller being rapidly accelerated up to several times its acceleration as well as the number of times the acceleration of gravity, and then at a rate per 70-100m / s from the impeller projectile out, first with the free-fall into the whirl crushing cavity material impact outside the impeller and broken, and with the impact of eddy crushing cavity material bed layer, is sprint onto the bed material rebound oblique top whirl crushing chamber, but also to change its direction of motion, deflected downward movement, rotation Road materials emitted from the leaves to form a continuous material curtain Sand, so that a materials in the turbine as well as the crushing cavity by two times the impact crushing effect. Throughout the crushing process, the material is self-reciprocal impact crusher, not in direct contact with the metal element. Since the channel from the impeller material emitted obliquely peripheral impact, forming materials in eddy crushing cavity rotational movement on the bed material, an eddy moving the grinding action between the material, due to the impact of friction between the pulverized material, crushed material discharged from the discharge port. Henan Senda Heavy Sand river gravel production with high performance stability, reasonable structure, high degree of automation, the entire production line in addition to equipment and routine maintenance of the boot down, the process is simple, almost no manual operation and other advantages, It is important to its high efficiency, low running costs vsi crusher, large output, high-yield, finished stones uniform size, grain shape is good, in line with the national high-speed material requirements.
