Our Trough Type Double Spiral Sand Washing Machine is a high-efficiency, heavy-duty cleaning equipment designed for washing, classifying, and desliming ores and aggregates in mining, quarrying, and construction industries
Product Overview
Our Trough Type Double Spiral Sand Washing Machine is a high-efficiency, heavy-duty cleaning equipment designed for washing, classifying, and desliming ores and aggregates in mining, quarrying, and construction industries. Especially suitable for processing high-clay, sticky, and difficult-to-wash materials, this machine effectively removes dust, mud, and impurities from minerals, ensuring clean output for downstream processing.
Widely used in manganese, iron, gold, and sand mines, this washer features a robust trough structure with dual spiral shafts that provide strong cutting and scrubbing action. It is the ideal solution for operations facing blockages due to muddy raw materials.
Working Principle
The machine operates through a combination of mechanical agitation and water flushing:
1. Feed: Raw material (ore or sand with clay) enters the washing tank via the feed chute.
2. Agitation: Two spiral shafts rotate in opposite directions, lifting and dropping the material repeatedly.
3. Scrubbing: The spiral blades vigorously stir and grind the material, breaking down mud lumps and separating impurities.
4. Washing: Clean water is added to create a turbulent flow that carries away fine silt and dirt through the overflow weir.
5. Discharge: Cleaned coarse material is pushed upward by the spiral blades and discharged from the top, while muddy water exits from the tail end.
This process ensures high cleaning efficiency and low loss of valuable minerals.
Key Features & Advantages
Strong Cleaning Power
Equipped with wear-resistant manganese steel spiral blades and a deep-tank design, it delivers powerful scrubbing for sticky clay and stubborn dirt.
Dual-Spiral Design (Optional)
The dual-shaft version enhances washing capacity and ensures even material distribution, ideal for large-scale operations.
Durable & Low Maintenance
●Sealed transmission system keeps water and sand away from bearings.
●High-quality gear reducer and heavy-duty rollers ensure long service life.
●Replaceable wear parts reduce downtime and operating costs.
High Efficiency, Low Water Consumption
Optimized water flow design reduces water usage while maximizing cleaning performance. Can be connected to sand recycling systems.
Stable Operation
Smooth running with low noise and vibration. Adjustable weir plate allows control over overflow particle size.
Wide Application Range
Suitable for both soft and hard ores, as well as construction aggregates, river sand, and alluvial minerals.
