With the development of technology, the development has broken machinery Impact crusher, has made considerable progress. Especially in the 1990s, the rapid growth of broken machinery production and sales, adding broken machinery production companies continue to increase the roll crusher, crushing machinery manufacturing enterprises make up to more than the home, can produce 0.5 ~ 30t vibrating crusher, 4 ~ 24t static roller crusher and 16 ~ 30t tire crusher varieties more complete range of products, the basic form capable of self-development and production of complete crusher manufacturing system, the gap between the technology level and among the international advanced level is gradually narrowing. This rapid growth of the situation, there will be broken machinery parts industry into a new period of development. 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 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 consisting of impeller rotation speed whirl crushing cavity new Sand, whirl crushing cavity can reside material form lining material, 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. Two, 5X series Sand Features 6, the optimal transmit port and internal smoother curved design, reduce the flow resistance of the material, greatly improve the capacity of the material. 7, dual bulk tray, simple, convenient way to achieve the two feed conversion. 8, the lower end of the spindle special sealing structure to ensure that no seal is not leaking. 9, using parts imported from Japan hydraulic lid device can be convenient and efficient mobile cover, so that the body's internal overhaul replacement parts saving labor 10, the selection of high protection class motors. This type of motor has a high efficiency, low noise characteristics. In line with the International Electrotechnical Commission (IEC) standard, F class insulation, IP54 / 55 protection rating.
