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 Sand, is rapidly accelerated in the impeller, its acceleration up several times as well several hundred 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 the impact of the crushing chamber together to whirl on the inside of the bed material is sprint onto the bed material rebound oblique whirl top vsi crusher crushing chamber, and to change its direction of motion, deflected downward movement, the material emitted from the impeller to form a continuous material curtain Thus, a material 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 new Sand, almost without human Advantages operation, it is important to its high efficiency, low operating cost, high yield, high yield, finished stones uniform size, grain shape is good, in line with the national high-speed material requirements. River sand, natural sand in the building has a lot of advantages, but with the improvement of the indicators required by the building, natural sand due to geographical differences in the distribution and generation of natural weathering conditions, and physical and chemical indicators showing volatility, which for concrete, especially high performance concrete is certainly not conducive to the stability of quality. Most importantly, with a significant reduction in infrastructure development and river sand resources, and the state strictly limited dredging sand, so finding new sand source is a priority infrastructure. 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.
