Product Details

Rotary Scrubber (Heavy Duty Clay Washer)

The Rotary Scrubber (Drum Scrubber) is the most powerful washing equipment for ores with high clay content and sticky mud. It is essential for Alluvial Gold, Manganese, and Bauxite processing.

Unlike a normal Trommel Screen, the Scrubber has a longer, non-perforated scrubbing section where rocks tumble and grind against each other to break up tough clay agglomerates.

Working Principle: Scrubbing & Screening

Utilizing the friction between rocks and the lifting action of the drum to disintegrate clay.

Feeding & Soaking

Ore and water enter the drum. The material soaks in the water while being lifted by the internal liners.

Violent Scrubbing

As the drum rotates, rocks fall and collide. This "stone washing stone" action breaks down the sticky clay matrix, liberating valuable minerals.

Discharge & Screening

The slurry moves to the rear trommel screen section. Oversized clean rocks are discharged, while fine pulp passes through the mesh for concentration.

Technical Choice: Rotary Scrubber vs. Log Washer

Both are for washing, but they suit different materials:

Feature	Rotary Scrubber	Log Washer (Spiral)
Material Size	Large Rocks (up to 230mm).	Medium/Fine (< 70mm).
Clay Content	High (Sticky Plastic Clay).	Medium.
Screening Function	Yes (Rear Trommel).	No (Washing only).
Capacity	Large (up to 180t/h).	Medium (up to 100t/h).

Core Advantages

1. Handle Sticky Clay

Designed specifically for washing ores with clay content > 30%. The long retention time inside the drum ensures complete disintegration of clay balls.

2. Heavy Duty Construction

Supported by 4 heavy trunnion rollers. The drum is lined with Rubber or Steel plates to protect the shell from wear and impact.

3. Integrated Screening

The discharge end features a polyurethane (PU) or steel trommel screen, allowing washing and sizing in a single machine, saving space and cost.

Typical Applications

● Alluvial Gold:
Washing sticky laterite gold ore. The clean slurry goes to Jig Machine.
● Manganese & Iron:
Removing clay impurities from lump ores to upgrade the quality.
● Bauxite Washing:
Separating silica and clay from bauxite.
● Tantalum-Niobium:
Washing weathered pegmatite or alluvial deposits.

Frequently Asked Questions (FAQ)

Q: How much water does it consume?

A: The water consumption is typically 1-2 times the ore volume (1-2 m³/ton). For very sticky clay, more water may be needed. Recycled water can be used.

Q: Can I use rubber tires to drive it?

A: Yes. We offer both Gear Drive (Standard) and Rubber Tire Drive. Tire drive is smoother, quieter, and has lower maintenance costs.

Q: How long do the liners last?

A: Rubber liners typically last 2-3 years, while steel liners last 1-2 years depending on abrasiveness. Rubber liners are better for scrubbing efficiency.
