The Application Field of the Mechanical Sand

In recent years, the qualified natural sand resources are on the less , so the artificial sand gradually became the main source of construction work . Currently, our Beijing Olympic project, Xiaolangdi reservoir Baoquan reservoir, Hongqiqu reservoirs, Gezhouba Tianwan River Power Plant, these key national projects all use the artificial sand to prepare the concrete, and both its construction sand and gravel bone material strict audit and inspection. In the existing engineering practice, the preparation of artificial sand from C10-C70 ordinary concrete and pumping concrete, configure a span prestressed concrete beam whose length is 64m.

However, if the mechanism of sand does not meet the requirements, the construction of key projects, housing, highways, high-speed railway will appear a variety of engineering quality problems, so as a mechanism of sand production enterprise, responsibility must be the production of high-quality qualified mechanisms of building sand sales to the market, prepared by high-performance concrete used in construction, so can largely avoid the bridge tatami floor back down "event, visible, high-quality artificial sand can configure high-performance concrete to increase the life of the housing, roads, railways and other infrastructure projects and key construction projects.

What problems should we pay attention to when we prepare the high-quality sand ? In the crushing system of sand making production line, the traditional simple jaw breaker, cone crusher, fine jaw breaker can not meet the requirements of the the senior architectural spaces materials, because basalt gravel in flakiness and the internal cracks gravel contents are too high, production mechanisms sand quality are not good too . So, to produce better quality mechanisms sand ,the counterattack crusher must be used as a secondary crusher or sand making machine as the last one broken shaping. Generally lagging behind the entire domestic Sand production technology, the lower the yield, the higher prices, so choose  hammer breaker is the most common, such as: Shandong, Hubei, Inner Mongolia, Gansu, Guangdong and other regions, and these market gravel machinery, sand production line equipment manufacturers, many kinds of hammer breaker our company produced have the features of  advanced technology, stable equipment performance and large market share . A lot of sand and gravel production enterprises use the configuration sand production line of our company , it is true that the sand production efficiency is high,the mechanical sand podwer produced by this machine is low, gradation and quality are super .
