Sand separator: also known as concrete sand or concrete sand separator Whey separation recovery equipment, is the core of concrete recycling systems, mainly used to clean the sewage tank and residual concrete washing separation and recycling gravel . The machine is designed using advanced concrete recovery technology, a combination of roller separation and spiral separation of filter characteristics of consumable parts of a lot of improvements, simple, intelligent control, the whole process unattended, convenient Quick, you save a lot of manpower, material and financial resources. Car parking system can be divided into single, double parking spaces, three parking spaces, you can increase or decrease depending on the requirements of the user, when the tanker stop to the set position, the system will automatically add water, automatic flushing, automatic sewage and waste chute of concrete into the sand separation system is required, the flushing process is fully automated. The device is simple mechanical structure, significant environmental benefits: smooth surface isolated gravel, sand and ash ≤1%, water ≤3-5%; washing water recycling, to achieve zero discharge of sewage; equipment wear, simple, easy Cleanup overhaul
