One piece of equipment integrates multiple processes, eliminating the need for multiple machines, saving on equipment, infrastructure, and land costs, especially suitable for projects with limited land availability.
Using cyclone separation technology, it recovers fine sand lost in traditional processes, increasing sand output by 10%-25%, optimizing grading, and directly increasing revenue.
Equipped with a high-efficiency water treatment system, it achieves wastewater recycling, saving over 80% of water, and the low-moisture filter cake is easy to dispose of, meeting environmental requirements.
The finished sand is clean, with low mud content (<3%) and low moisture content (10%-15%), meeting the high-end requirements of high-grade concrete and dry-mix mortar.

sand washing and recycling integrated machine
A large-scale granite sand production line in Southeast Asia, whose original process involved direct use of a wheel-type sand washer after vibrating screening, suffered from serious fine sand loss, high powder content in the finished sand, and significant wastewater treatment pressure.
Solution: We customized an FC-15 integrated sand washing, dewatering, and recovery machine for them, replacing the original end-of-line sand washing equipment.
1. Output and recovery: The hourly processing capacity reached 150 tons, and the fine sand (0.16-0.6mm) recovery rate reached over 90%, increasing the overall sand output rate by approximately 18%.
2. Product Quality: The finished sand has a stable clay content of less than 2.5%, a moisture content reduced to 12%, and a controllable fineness modulus, making it highly favored by downstream ready-mix concrete plants.
3. Environmental Benefits: Equipped with a small filter press, the system achieves over 95% recycling of wash water, resulting in virtually zero wastewater discharge and successfully passing environmental inspections.
The sand washing and dewatering integrated equipment is widely used in fields such as manufactured sand production, natural sand purification, tailings recovery, and recycled aggregate processing from construction waste. It is a core piece of equipment for improving sand and gravel quality, achieving efficient resource utilization, and promoting environmentally friendly production.
The working principle of the integrated sand washing and dewatering equipment is to achieve efficient separation and recovery of sand, water, and mud through a three-step process: classification washing, hydraulic cyclone concentration, and mechanical dewatering.
1. Classification Washing: The raw materials enter the washing tank, where they are tumbled and rubbed under the action of the impeller, removing surface impurities, and the mud powder is carried away by the water flow.
2. Fine Sand Recovery: The muddy water containing fine sand enters the cyclone separator, where preliminary separation of sand, water, and mud is achieved under centrifugal force. The fine sand is then recovered after secondary dewatering by a dewatering screen.
3. Muddy Water Treatment: The separated turbid water enters a sedimentation tank or a matching filter press equipment. The clean water is recycled, and the mud is pressed into low-moisture mud cakes, achieving zero discharge.
This process integrates mechanical cleaning, centrifugal separation, and screening dewatering in a single piece of equipment, simultaneously completing "washing, recovery, dewatering, and water recycling," balancing efficiency and environmental protection.

Two models cover the range. The 2610+1225 unit outputs 30-80 t/h of sand with 26.9 kW total power, and the 2915+1530 unit outputs 60-120 t/h with 35.5 kW. Both use a 60 mesh screen deck, and the impeller diameters are 2450 mm and 2560 mm.
Three stages run in one unit: classification washing, cyclone concentration and mechanical dewatering. Raw material is scrubbed in the washing tank, the muddy water then enters a cyclone separator that splits sand, water and mud under centrifugal force, and the recovered fine sand is dewatered on a screen. Clean water returns to the circuit and the mud is pressed into low-moisture cakes.
Cyclone separation recovers fine sand that traditional washing loses, raising sand output by 10%-25%. In a 150 t/h granite line in Southeast Asia, a Baichy FC-15 integrated sand washing, dewatering and recovery machine recovered over 90% of the 0.16-0.6 mm fraction and increased the overall sand output rate by about 18%.
Finished sand leaves the sand washing and dewatering integrated equipment with a mud content below 3% and a moisture content of 10%-15%, so it can be loaded straight onto trucks. In the Southeast Asia granite case, clay content held below 2.5% and moisture fell to 12%, giving a controllable fineness modulus for ready-mix concrete plants.
The integrated water treatment system recycles wash water, saving over 80% of fresh water. In the 150 t/h granite case in Southeast Asia, a small filter press lifted wash-water recycling above 95% with virtually zero wastewater discharge, and the low-moisture filter cake was dry enough to stack and dispose of.
