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) new Sand, 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 incoming shunt, so that part of the material through a feeding tube directly into the center of the impeller is gradually accelerated to a high speed projectile out Sand, so another part of the material from outside the central feeding tube into the outer side of the bypass whirl crushing cavity of the impeller, the impeller is from out of the high-speed projectile material impact crusher, without increasing power consumption, increase 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 abrasion resistant vortex mouth moving blocks on top of the crushing chamber liner wear, 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. Sand should be installed to withstand four times the weight of the machine on the basis of concrete or steel, but also according to Sand different venues where the plant is in operation or in the open-air operations vsi crusher, sand making adjustments should be installed plane perpendicular to the horizontal axis. Installation of third-generation Sand Sand, top of the machine should be lifting equipment, should also consider whether the overall weight of the machine capable of lifting equipment, sand making machine when lifting over the side of the space should be left overhaul should be left the space required. Before installing the machine to view the packing list, the number of parts to see the match is complete, whether detrimental during transport.
