Log Washer for Stone Washing
1. Product Introduction
Log Washer for Stone Washing is a heavy-duty washing equipment specially designed for cleaning various types of stones and rock materials. It is widely used in sand and gravel production lines, quarries, and aggregate processing plants.
Raw stones are usually covered with clay, mud, dust, and weathered layers, which result in high mud content and low purity in final products, making them unsuitable for construction and building material standards.
This machine is designed for powerful scrubbing and deep desliming. It effectively removes stubborn clay and surface impurities, significantly improving stone cleanliness and product quality. It is a key pre-washing equipment for producing high-quality aggregates.
2. Working Principle
The equipment adopts a pure physical cleaning process combining mechanical scrubbing, water washing, and gravity separation to automatically separate stone, clay, and impurities.
1. Clay scrubbing and disintegration
Stones enter the inclined trough, where spiral blades continuously tumble and rub the material. This action breaks up cemented clay and removes thick mud layers from stone surfaces.
2. Hydraulic washing and stratification
Continuous water spraying is applied. Clean, heavy stone particles settle naturally, while light clay, dust, and fine particles remain suspended in water, achieving effective separation.
3. Clean stone discharge
After washing, qualified stones are steadily lifted and discharged by spiral blades. After dewatering, they are sent to downstream screening or shaping equipment.
4. Slurry overflow discharge
Suspended mud and waste materials are discharged through the tail overflow outlet, ensuring complete separation of stone, mud, and water, and preventing re-contamination.
3. Advantages
1. Excellent stone cleaning performance
Strong mechanical scrubbing effectively removes heavy clay and dirt from large and highly contaminated stone materials, significantly reducing final mud content and improving aggregate quality.
2. Low material breakage and high yield
The gentle tumbling design minimizes damage to raw stones, maintains particle integrity, reduces material loss, and increases product yield.
3. Heavy-duty and wear-resistant design
Key spiral blades are made of thickened high-manganese steel, offering strong resistance to impact and abrasion, suitable for harsh quarry environments with stable and reliable operation.
4. High capacity and anti-blocking performance
Large trough design ensures continuous processing of high-volume stone materials without blockage or accumulation, suitable for large-scale production lines.
5. Energy-saving and easy maintenance
Pure physical washing process without chemical additives. Can be equipped with a water recycling system to reduce water consumption. Modular design allows easy maintenance and low operating cost.
6. Wide applicability
Suitable for washing river pebbles, granite, limestone, crushed stone, and other aggregates. Fully compatible with various sand washing and aggregate processing plants.
4. Application Scenarios
Widely used in quarry stone washing, aggregate desliming, batching plant material cleaning, artificial sand production pre-treatment, and construction material upgrading.
It is a dedicated washing solution for producing high-cleanliness, high-quality aggregates in the construction and building materials industry.
