Attrition Scrubber

FRP Attrition Scrubber, also known as an Attrition Cell or Attrition Washer, is designed for deep surface cleaning of fine mineral particles. It is especially suitable for silica sand, quartz sand, glass sand, foundry sand, and other industrial minerals where ordinary washing cannot remove surface contamination effectively.

It helps improve product cleanliness, reduce turbidity, improve whiteness, reduce surface iron contamination, and create better conditions for downstream processing.

Key Benefits / Advantages

Imported Weir Linatex® Rubber Liners

Wear resistance is one of the most important factors in attrition scrubber performance. FRP Attrition Scrubbers are lined with imported Linatex® rubber from Weir for superior wear resistance in abrasive slurry conditions. Compared with ordinary lining materials, high-quality rubber lining helps extend service life, reduce maintenance frequency, and protect the tank structure during long-term operation. For silica sand and quartz sand projects, where the material is hard and abrasive, liner quality directly affects equipment reliability and operating cost.

Double-Cell and Multi-Cell Arrangements

FRP Attrition Scrubbers are available in double-cell and multi-cell arrangements. Multiple cells increase effective retention time and help reduce short-circuiting of slurry. This allows the material to pass through several scrubbing zones and receive more uniform treatment. For projects with higher surface contamination or stricter product quality requirements, multi-cell configuration can provide stronger and more stable scrubbing performance.

Motor-Reducer Drive, Not Belt Drive

FRP uses a motor-reducer drive system instead of belt drive. This high-configuration design provides more stable torque transmission and reduces common maintenance problems caused by belt slipping, belt tension adjustment, and frequent belt replacement. For continuous industrial sand production, stable drive performance means fewer unexpected shutdowns and more reliable operation. No belt slipping. Lower routine maintenance. More stable torque transmission.

Working Principle Visual

Working Principle

Material is continuously fed into the attrition cell as a high‑density slurry. Driven by the high‑speed rotation of the impeller, a powerful internal circulation flow is generated within the tank. Particles are continuously lifted, rolled, and thrown into intense collision and friction against each other.

The core scrubbing force does not come from direct contact between the impeller and the particles, but from the inter‑particle friction and attrition generated within the controlled high‑density slurry environment. This particle‑on‑particle action effectively removes surface coatings, iron stains, and contaminants that conventional water washing or simple agitation cannot eliminate.

In the production of high‑purity silica sand and glass sand, this process not only improves surface cleanliness but also creates ideal feed conditions for downstream purification stages such as flotation, magnetic separation, or acid leaching — ensuring the final product meets the highest purity standards required by the glass and electronics industries.

Problems Attrition Scrubbers can solve

clay films attached to sand particle surfaces, causing the product to remain cloudy even after ordinary water washing;

serious agglomeration of fine particles, reducing downstream classification efficiency; high turbidity and insufficient cleanliness of finished sand;

insufficient whiteness of quartz sand due to surface iron or clay contamination;

unstable flotation recovery caused by mineral surfaces being covered with mud or slime;

Designed for High-Value Industrial Sand

FRP Attrition Scrubber is mainly recommended for projects where product quality matters more than simple mud removal.

Typical applications include: silica sand washing and purification; quartz sand surface cleaning; glass sand processing; foundry sand cleaning; high-purity industrial sand preparation; flotation feed preparation; mineral surface cleaning before magnetic separation or flotation.

For silica sand and glass sand customers, surface contamination directly affects whiteness, iron content, turbidity, and final product grade. If the sand surface is not properly cleaned, even a well-designed downstream process may not achieve stable results.

Attrition scrubbing helps expose cleaner particle surfaces and improves the effectiveness of downstream desliming, classification, magnetic separation, flotation, and dewatering processes.

Frequently Asked Questions

FAQ for Attrition Scrubber

Attrition scrubbing relies on strong friction between particles. If the pulp is too diluted, particles are too far apart and the process becomes mainly water agitation, not effective scrubbing.

Higher pulp density increases particle contact, collision and friction, helping remove clay films, slime coatings and surface contaminants more effectively.

In most silica sand and quartz sand processing plants, the attrition scrubber is installed after pre-washing, screening or classification, and before desliming, magnetic separation, flotation or dewatering.

The exact position depends on the feed condition, clay content, impurity type, target product quality and complete process design.

Attrition scrubbers are commonly used for silica sand, quartz sand, glass sand, foundry sand, high-purity industrial sand and various fine mineral particles.

They are especially suitable when the main problem is surface contamination, clay coating, slime coating, fine particle agglomeration or unstable product cleanliness after ordinary washing.

To recommend a suitable attrition scrubber, FRP usually needs to know the raw material type, feed size, processing capacity, clay or slime content, impurity type, current washing result, target product standard and downstream process requirements.

With this information, FRP can evaluate whether attrition scrubbing is necessary and how to integrate it into the complete processing line.
