Severe-Abrasion Resistant Screw Washer for Granite Chip Processing

Conquering Quartz-Induced Wear in Hard Rock Applications
Granite's high quartz content (25-60%) destroys conventional washers in months. OCP's abrasion-resistant screw washer features:

• Tungsten-carbide clad flights (1,250 HV hardness)

• Replaceable NiHard IV wear shoes

• Heavy-duty planetary gearboxes (5x industry standard L10 life)

• Oil-bath bearing protection

Tested on Malaysian granite feed, our screws deliver 11,000+ operational hours - triple the industry average.

Precision Gradation Control
Adjustable overflow weirs and variable-speed drives (5-25 RPM) enable real-time control of product silt content from 3-15% to meet diverse concrete and precast specifications. This granite chip processing solution transforms marginal materials into premium aggregates.
