FG Series Spiral Sand Washer
Fine sand washing · Classification · Dewatering · Low energy consumption
The FG Series Spiral Sand Washer is a high-efficiency screw sand washing machine designed for cleaning, classifying, and dewatering fine sand materials.
It effectively removes mud, clay, and impurities from sand and gravel to improve the quality of finished aggregates.
This machine is widely used in metallurgy, building materials, hydropower projects, quartz sand processing plants, construction aggregate production, and manufactured sand washing lines.
The spiral blade structure provides continuous scrubbing and material transportation, making it especially suitable for manufactured sand, river sand, quartz sand, and materials with higher clay content.

Performance Features
Efficient Washing: The rotating spiral blade continuously mixes and scrubs sand materials, helping remove clay, mud, and impurities from the surface of aggregates.
Multi-Function Operation: Washing, dewatering, and classification functions are integrated into one machine, reducing equipment investment and saving installation space.
Simple Structure & Easy Maintenance: The machine structure is practical and compact, including spiral blades, feed inlet, discharge outlet, and water supply system for convenient operation and maintenance.
Energy Saving Design: The equipment operates with relatively low energy consumption while maintaining stable working efficiency, helping reduce operational costs.
Wide Material Application: Suitable for limestone, river pebbles, granite, basalt, quartz, weathered sand, diabase, and other aggregate materials.
Working Principle
Sand and water enter the washing tank through the feed inlet and are mixed with the rotating spiral blades.
Under the action of the spiral, the material moves forward continuously while lighter mud and impurities are separated and discharged.
During the process, clean sand is gradually classified, dewatered, and discharged from the outlet, while wastewater and impurities flow out from the overflow outlet.
