HY-800/2 Screw Washer

HY-800/2 Screw Washer is an industrial washing machine produced to meet the sand cleaning and classification needs of medium-sized mines, stream bed enterprises and aggregate facilities. Working with a water consumption flow rate of 65-230 m³ per hour, depending on the degree of contamination of the material, the screw washer reaches a sand processing capacity of 80 tons per hour, thanks to its expanded washing chamber and optimized helical lines.

It cleans the aggregate fed into the washing tub by constantly scrubbing it with a double-sided helical mechanism. HY-800/2 directs clay lumps and light particles to the discharge weirs with the buoyancy of the water. Thanks to its heavy-duty independent double motor-reducer group, the machine can work non-stop even at the most intense material loads, and thanks to its wear-resistant rubber surface coatings, it offers high performance for many years in long-term projects without experiencing structural wear at a single point.

• Effective Cleaning of 0–10 mm Fine Aggregate: It dissolves clay, silt and organic pollutants in the material and removes them from the system, providing a high quality final product suitable for concrete and asphalt production.
• High Washing Efficiency with Double Screw Paddles: Two screw paddles positioned side-by-side maximize washing performance.
• Simultaneous Natural Dewatering: The upward inclined transport movement of the helix structures allows the material to filter, reducing the moisture content and providing ease of stocking.
• Independent Dual Drive System: A separate electric motor and heavy-duty reducer are used for each helical shaft; This increases operating reliability while optimizing torque distribution.
• Rubber Coated Helix Structure: The service life is extended by covering the shafts with high-resistant rubber linings against mechanical deformation caused by abrasive and abrasive rocks.
• Advanced Classification and Sedimentation Capability: The trough design minimizes material loss and ensures precise classification by preventing fine sand particles from escaping with the water.
• Heavy Duty Sheet Metal Body and Sealing: Water tightness is guaranteed with its body architecture and labyrinth external bearing system, which is protected against corrosion that can be caused by water and mud.
