Intensive Material-on-Material Scrubbing
Twin counter-rotating shafts generate aggressive shear and abrasion between particles, achieving complete dispersion of clay-bound materials and removal of coatings.
The FRP Log Washer is a twin-shaft, high-capacity wet processing machine designed to handle tough, heavily contaminated, or clay-bound feed materials. As a high-intensity log washer for clay removal and ore washing, it delivers intensive material-on-material scrubbing to break down plastic clays, soft rock, and cemented aggregates, removing impurities that conventional washing systems cannot effectively eliminate.
By effectively disintegrating and cleaning sticky, high-clay ores or aggregates, the log washer ensures that the final product meets the most demanding industrial cleanliness standards and is ready for downstream processing.
When your raw feed contains excessive clay or soil that reduces downstream equipment efficiency and product quality, the FRP Log Washer provides the critical washing step for efficient clay removal, aggregate washing, and mineral processing, enabling the production of high-quality, high-value aggregates or ores.
The FRP Log Washer operates by feeding material and water into an inclined tank, where twin counter-rotating shafts fitted with paddles generate intensive agitation, shearing, and scrubbing action to break down agglomerates, disperse sticky clay, and liberate surface impurities. During the washing process, lighter clay, mud, and fines remain suspended in the slurry and are discharged through the overflow, while heavier, cleaned material is conveyed upward and discharged in a relatively dewatered condition, ensuring efficient clay removal and preparing the feed for downstream mineral processing or aggregate washing.
Pre-Treatment & Feed Conditioning → Used as a pre-treatment stage in mineral processing plants to break down clay lumps, liberate valuable minerals, and improve feed conditions for downstream processes such as jigging, shaking tables, and gravity separation.
Construction Materials & Infrastructure Processing → Used for intensive washing and upgrading of clay-rich natural sand, weathered materials, and low-grade aggregates, improving material stability and suitability for construction applications.
A log washer is primarily used in mineral processing plants for scrubbing and removing clay, mud, and surface impurities from ore before downstream separation.
It is commonly applied in:
*Gold ore processing – removing clay to improve gravity separation efficiency and gold recovery
*Iron, chrome, and manganese ores – desliming and cleaning to enhance beneficiation performance
*Bauxite and laterite ores – breaking down sticky material and improving feed conditions
*Silica sand and industrial minerals – removing coatings and impurities to increase product purity
👉 Log washers are especially important in operations where high clay content affects recovery, separation efficiency, and overall plant performance.
How do I choose the right Log Washer model?
The right log washer model should be selected based on material type, clay content, feed size, required capacity, and downstream process requirements. Among these factors, clay content is especially important, as high-clay and sticky materials require stronger scrubbing intensity and sufficient retention time. Feed size, material stickiness, and throughput will also influence the choice of machine size, paddle arrangement, and operating configuration. Straight paddles are typically used for intensive scrubbing and rapid dispersion of high-plasticity clay, while helical paddles provide more stable conveying and more uniform scrubbing for different material conditions. For accurate selection, material analysis is recommended.
