Coarse Material Washer Working Principle

Coarse material washers are used to remove a limited amount of dirty material from the coarse aggregate. This material includes very water-soluble slimes, silts, soft clay, and organic particles.

Clean coarse aggregates in the most efficient way

MEKA Coarse Material Washers are specifically designed to efficiently remove clay, silt, and other contaminants adhering to the surfaces of aggregates and ores. With their twin-shaft helical paddle structure, they transport material upward with a powerful scrubbing action during the washing process. At the same time, the directed water flow flushes out fine particles and eliminates remaining residues in the final rinse line.

The Ni-Hard paddles used in MCW Series Coarse Material Washers offer high wear resistance, while the custom gearbox ensures superior performance under high impact loads. The body angle is adjustable between 0° and 5°, allowing the washing time to be optimized for different applications, ensuring maximum cleanliness.

Compared to competitors, MEKA Coarse Material Washers stand out with their significantly heavier and more rigid body structure and easily replaceable wear parts, offering low maintenance costs and long service life. It is an ideal solution for removing hard and sticky clays, plastic content, and organic materials.
