The sand separator is also called the concrete recovery machine, which is the environmental protection type equipment for recycling and reusing of the concrete after mixing the concrete mixing station. The equipment has the advantages of compact structure, low energy consumption and strong ability to recover sand and stone. It is one of the necessary equipment for acceptance of concrete mixing station.
It is well known that concrete is the main raw material in the construction of high speed railway, especially the high marked concrete used in bridges and piers. High speed railway construction and concrete transport distance, difficult road, and combined with the characteristics of high grade concrete short setting time, so the need for timely delivery of concrete tank cleaning so as not to affect the next use, sand separator not only reduces the environmental emissions for construction projects to save a lot of money, so the sand in the construction of high-speed rail the project is one of the indispensable equipment in the separator.
