The FRP Fine Material Spiral Washer is a robust and efficient solution for the washing, classification, and dewatering of sand, fine aggregates, and mineral materials up to 10 mm in size.
As a fine material spiral washer designed for fine material processing, it effectively removes clay, silt, and lightweight impurities, ensuring a clean, well-graded final product suitable for use in concrete, mortar, asphalt, and industrial sand production.
With a durable structure and simple maintenance requirements, the FRP Spiral Washer is available in both single-screw and twin-screw configurations, offering flexibility to meet different capacity and cleanliness requirements.
Flexible Design for Different Material Conditions
The FRP Fine Material Spiral Washer is designed with a strong focus on wear resistance, classification control, and adaptability to different material conditions. The spiral flights and key wear areas can be equipped with polyurethane, high manganese steel, or rubber liners depending on the application. Polyurethane liners offer excellent wear resistance for sand and fine aggregate with moderate abrasion, high manganese steel liners are better suited for high-impact and highly abrasive materials, while rubber liners provide effective cushioning and noise reduction in wet, fine material processing environments. The machine is also equipped with an adjustable or customizable overflow weir system to control the cut point of fines separation and final product gradation. Single or twin screw configurations are available to match different capacity and washing requirements. Combined with an inclined trough design, optimized spiral pitch, and flexible integration with downstream equipment such as dewatering screens, the system ensures stable conveying while enabling effective control of fines recovery, product cleanliness, and overall process adaptability.
