LZ Sand Recycling System

Sand recycling machine has been specifically designed to recovery fines mixed in muddy water that discharged from sand washer machines, as well as sculting, desliming dewatering. The highly efficient fines recovery is efficiently improve the economic benefit, reduce disposal cost of tailings and the pollution and damage. Fines recovery machines are suitable for widely used in sand and gravel washing plant, glass raw material processing system, artificial sand production line, coal mining plant, coarse coal slurry recovery, environmental protection engineering and mud purification. sand recovery machine How sand recycling machine work? Slurry pump transports the muddy water overflowed by sand washer machine to high pressure hydrocyclone separator, and solid-liquid separation is started to perform under high-speed centrifugal force and rated feed pressure. When the concentration increased to 60-70%, fine sand is supplied to dewatering screen through grit nozzle. Under the vibration motion, fine sand is effectively separated from the water, and then discharged through outlet to form stock piles. A small amount of fine sand, mud is returned to washing tank through the return tank, and is circulated and reciprocated, thereby achieving the purpose of recovering, dehydrating, and dry discharging of fine sand in the muddy water. The concentration of recycled materials by LDHB sand recycling machine is 70%-85%. Adjustable fineness modulus can be achieved by changing the pump speed, mortar concentration, adjusting the amount of overflow water, and replacing the mortar nozzle. Features 1. Effectively recycle >95% fine sand. 2. 12%-15% water content of dewatered sand. 3. Polyurethane screens with blocking, and longs service life than other screen panels. 4. Hydrocyclone separator is lined with polyurethane, which improves the service life of the whole device and can smoothly complete the work of slurry concentration and liquid clarification. 5. Fully recovered fine particles reduce the workload and cleaning cost of sedimentation tank. 6. Recovered fine materials can be directly operated, and supplies to the market, which reduces the stacking time. 7. Specific solution can be designed according to different requirements of users.

No.6 Fine Sand Recycle System

Fines recovery units is a combination of dewatering screen and hydrocyclone that is specifically developed integrates dewatering, screening and fine material recovery on the basis of the original recycling machine, and achieves the effect of multi-purpose machine. Fines recovery unit is generally directly used at the rear of sand washer, dewatering screen further dehydrates the finished material of sand washing machine, and recovery system effectively extracts and recovers the fines in tail water overflowed by sand washing machine to realize the coarse and fine sand centralized dehydration and recovery. Working principle About No.6 sand recycling system, we still choose polyurethane screen as its main screening part, and add recycling part on TS dewatering screen. Sand after sand washer is fed onto polyurethane screen for dewatering, waste sand water through steel chute or rubber pipe in water tank and extracted by slurry pump into high pressure sediment separator, fine sand 0.16-3mm is sprayed onto polyurethane screen also for de-watering, the waste water is back to return box and flowing out. Features 1. Both dehydration and recovery functions, which solves the problem of high fineness modulus and low stone powder content of finished sand in artificial aggregate processing system. 2. Above 95% fines recovery rate brought the direct economic benefit to customers is more than 15%, which has both environmental protection and economic benefits. 3. Improve the quality and productivity of finished products, fully solve the problems of sand washing machine. 4. Secondary washing function make the products cleaner. 5. Fines recovery unit can also provide more flexible process configuration for customer to meet the different production requirements besides the existing fixed group form. 6. Multi-function, easy to operate, saving investment cost and floor space.
