100 Tons per hour sand washing plant/sand washing equipment/sand washing machine
Overview
This 100 tons per hour sand washing plant integrates feeding, screening, scrubbing, classification, fines recovery, and dewatering into one compact system. As a complete piece of sand washing equipment, it is designed for manufactured sand, natural river sand, and tailings processing. The system delivers high output, low fines loss, and dry stackable waste.
Key Components
Feed hopper with vibrating grid
Trommel screen with high-pressure water jets
Waste rock conveyor belt
Spiral Sand Washer (double spiral type)
Hydrocyclone
Fine sand recovery system (dewatering screen + slurry pump)
Sand product conveyor belt
Main Functions
Raw material enters the trommel screen for washing and sizing. Oversize waste rock is removed via the waste rock conveyor. The undersize material feeds into the Spiral Sand Washer, where twin spirals scrub clay and impurities from sand particles. The discharge then enters a hydrocyclone for classification. Coarse sand discharges to a dewatering screen, while fine sand and water overflow to the fines recovery unit, capturing particles down to 40µm. The final dewatered sand (12-15% moisture) is stockpiled by the product conveyor.
Application Scenarios
This sand washing plant is ideal for:
Quarries and crushing lines processing limestone, granite, or basalt into manufactured sand.
sand dredging operations that clean muddy river sand for construction use.
Mining sites recovering valuable sand from tailings.
Concrete batching plants requiring high-quality plaster or concrete sand.
Key Advantages
True 100 TPH Capacity – Continuous operation at 100 metric tons per hour under typical feed conditions.
High Fines Recovery – The hydrocyclone + recovery system captures over 95% of saleable sand from 40-400µm, significantly improving yield compared to a screw washer alone.
Effective Scrubbing – The Spiral Sand Washer removes clay films, producing clean sand meeting ASTM C33 or GB/T 14684 standards.
Low Water Consumption – Supports closed-loop water recycling; makeup water below 15 m³/h.
Dry Waste Disposal – The waste rock conveyor produces dry, stackable oversize, eliminating wet tailings.
Compact Footprint – Modular design requires only 25m x 15m area, reducing civil costs.
Why sand dredging Benefits
In sand dredging applications, this sand washing equipment efficiently separates organics, silt, and clay from river-extracted material. The integrated Spiral Sand Washer ensures thorough cleaning, while the fines recovery system prevents loss of valuable fine sand that traditional dredging methods often waste.
