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 basalt crusher, so that part of the material through a feeding tube directly into the center of the impeller is gradually accelerated to a higher 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, 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 Sand, whirl crushing cavity can reside materials, forming materials lining the crushing process, the material 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. Fourth, the general rotating machine empty load running time of 4 hours, feed size load test run in strict accordance with the specifications of various models, greater than the specified prohibited materials into; uniform continuous feed, water content of not less than 10-15% (available Depending on the material), the feed-through impact PCL reach full capacity until Sand; 8-24 hours load test run five times, check before starting Sand observe vortex chamber door is closed, to prevent the material from the observation of vortex chamber door Sand out of the factory, dangerous. Check the boot order of the impeller and transportation equipment: 1, nesting - → Sand - → feed 2, Sand must load start until after the crusher is operating normally before feeding. 3, stop and turn the opposite order. Six, Sand feed size in strict accordance with the requirements, greater than the specified prohibited materials into the crusher, otherwise, it will cause an imbalance of the impeller and impeller Sand excessive wear vsi crusher, even clog impeller channel and center into feeding tube, so Sand does not work, find great material should be immediately removed. Seven former host Sand stopped working, stop feeding, otherwise it will cause impeller crushed, burned the motor. Feeding should be uniform. Sand during operation, without severe vibration and abnormal noise, otherwise, you should stop to check. Dry lubrication oil lubrication, using car grease or 3 # lithium grease. Sand after every 100 hours add the right amount of grease. Senda Heavy absorb foreign advanced technology combined with domestic production environment, to create a more consistent domestic usage Sand, set excellent performance, environmentally friendly energy, reasonable price in one, is the domestic sand industry has a new development. River gravel crusher wide range of applications, the general river gravel Sand way to overflow into the feed material, feed the same size of the impeller. Such material situation to the next, to the amount of material into the impeller reaches full load operation (ie, all motor power play), when further increasing the feed to overflow into the outer whirl crushing cavity of the impeller.
