5TPH-200TPH Log Washer Sand Washing Machine For High Clay Ore

Log Washer for High Clay Ore

1.Product Introduction

The Log Washer, also known as a High-Intensity Agitating Washer or Twin-Shaft Ore Washer, is a highly efficient cleaning system specifically designed to handle high-clay and difficult-to-wash ores. Its core structure consists of a U-shaped trough and a pair of counter-rotating shafts equipped with high-strength mixing paddles (typically arranged in a log-spiral pattern). Through intense mechanical shearing and attrition, it thoroughly decomposes stubborn clay lumps to achieve efficient separation of ore from mud.

2.Application

• Metallic Ores: Chromite, tin, tungsten, phosphate, bauxite, iron, and manganese ores containing high levels of plastic clay.

• Non-Metallic Minerals: Barite, apatite, limestone, and silica sand requiring deep desliming.

• Industrial Raw Materials: Pre-treatment of construction aggregates, coal, and metallurgical raw materials to prevent mud balls from clogging crushing and screening equipment.

• Special Scenarios: Ideal for materials with severe weathering, high cementation, or high organic content, such as oil sands and iron oxide ores.

3.Working Principle

1. Feeding: High-clay ore enters from the lower end of the U-shaped trough while fresh water is injected.
2. Intense Agitation: Two shafts equipped with spiral paddles rotate in opposite directions. The paddles are interlaced to perform cutting, scrubbing, shearing, and stirring, ensuring that clay lumps are completely disintegrated.
3. Separation & Discharge: The cleaned ore particles are propelled by the paddles toward the upper end of the trough and discharged. Fine mud and impurities form a slurry and are discharged from the overflow port at the rear of the trough, completing the washing and classification process.

4.Advantages

• Superior Desliming Capability: Its ability to break down mud balls in high-viscosity, difficult-to-wash ores far exceeds that of standard spiral or trommel washers.

• High Processing Capacity: Single-unit throughput ranges from 20 to 150 tons per hour, meeting the demands of large-scale mines and aggregate plants.

• Robust and Durable Construction: Key components are manufactured from high-manganese steel or wear-resistant alloys, offering excellent impact and abrasion resistance for a long service life.

• Multi-functional Integration: Combines washing, desliming, and classification into one step, significantly reducing the load on downstream equipment.

• High Adaptability: Capable of processing coarse-grained ores with a maximum feed size of 50–70mm, adapting to various complex mineral properties.
