Abstract: Sand able to start at the main or a comprehensive ban on Chinese popular river sand dug from China. In 2005, the state issued a series of regulations third generation of Sand, river sand ban on large-scale excavation behavior, for a time, resulting in a sand source of tension, in addition, sand than natural sand has a larger surface area, higher with sand preparation of concrete strength. Secondly, sand production can be combined with gravel production process, greatly reduce production costs mechanism sand. Finally, the sand is conducive to the comprehensive utilization of mineral resources, not only to solve environmental problems and improve the utilization of natural resources. Efficient crushing machine plays an irreplaceable role as the sand core production line of broken equipment. Faced with these phenomena and problems, sand production will have a significant market opportunity vsi crusher, manufacturing high-quality sand and gravel in order to become a gold industry. 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, 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 of new Sand, greater than the specified prohibited materials into the crusher, otherwise, it will cause an imbalance of the impeller and impeller Sand excessive wear, or 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. With the development of technology, broken machinery development so far, 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, so that broken machinery manufacturing enterprises up thousand homes, capable of producing 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, Yuxin Senda (certified), Huangshan Sand Co., Ltd.
