Spiral Sand Washer for Coarse Stones

EPIC Spiral Sand Washer for Coarse Stones adopts a targeted structural upgrade based on the physical characteristics of coarse stone materials, filling the market gap in professional coarse aggregate washing equipment.

Exclusive Structural Characteristics

1. Expanded Washing Cavity Structure: The widened and deepened trough design provides sufficient moving space for large-size coarse stones, avoiding material stacking and incomplete flipping during washing.
2. Widened-pitch Spiral Blades: Customized large-pitch spiral structure adapts to coarse stone movement rules, ensuring uniform material propulsion and thorough impurity scouring without particle blocking.
3. Enhanced Impact Resistance Structure: Key bearing parts are thickened and reinforced to withstand continuous impact and extrusion of high-density coarse stone aggregates, improving operational stability.
4. Large-flow Water Distribution System: Matches high-volume water supply structure to form strong water scouring force, effectively washing away stubborn mud and clay on coarse stone surfaces.
5. Anti-blockage Discharge Design: Optimized material outlet and overflow structure ensures smooth discharge of cleaned coarse stones and timely discharge of muddy wastewater.

Unique Processing Superiorities

1. Higher Coarse Stone Cleaning Rate: Professional spiral stirring and high-flow water scouring thoroughly remove stubborn mud and clay on coarse stone surfaces, with cleaning rate far exceeding ordinary equipment.
2. Zero Coarse Particle Crushing Loss: Reasonable spiral speed and structural design avoid excessive extrusion of coarse stones, maintaining complete aggregate particle shape and improving finished product quality.
3. Strong Anti-blockage Ability: The large-caliber washing cavity and unobstructed material passage effectively solve the stacking and blocking problems easily occurred in coarse stone processing.
4. Adaptable to Complex Raw Materials: It can handle coarse stones with high mud content and high viscosity, stable operation without material accumulation failure.
5. High Production Efficiency: Optimized material propulsion track realizes continuous feeding and discharging, supporting high-efficiency batch production of coarse aggregates.

Industry Application Boundaries

1. Crushed Aggregate Production Lines: Purify machine-made coarse stones and crushed aggregates to provide high-quality raw materials for finished stone products.
2. Road Construction Engineering: Process clean coarse stone aggregates for road base, pavement and highway supporting facilities.
3. Water Conservancy Dam Projects: Supply high-purity coarse stones for dam foundation, slope protection and water conservancy infrastructure construction.
4. Mine Raw Material Processing: Clean coarse mineral aggregates, remove surface impurities, and improve the grade of mine finished materials.

Daily Operation Maintenance Tips

1. Regularly check spiral blade wear: Coarse stone scouring causes gradual blade wear; timely inspection and replacement ensure stable stirring and cleaning capacity.
2. Keep washing cavity unobstructed: Clean residual coarse particles and sediment in the tank after daily shutdown to avoid hard accumulation affecting next operation.
3. Inspect transmission operating status: Check the operating sound and lubrication condition of transmission parts to ensure sufficient power for coarse stone stirring.
4. Calibrate water supply flow: Adjust water volume according to coarse stone mud content to balance cleaning effect and water resource utilization efficiency.
5. Fasten structural bolts: Regularly check and fasten frame and tank fixing bolts to prevent loosening caused by long-term coarse stone vibration and impact.

Common Operational Consultation

1. Q: Why use special equipment for coarse stone washing instead of ordinary sand washers? 

A: Ordinary sand washers have narrow cavities and small spiral pitch, which are prone to blocking, incomplete cleaning and particle crushing when handling coarse stones. This professional equipment is fully optimized for coarse particle characteristics with better processing effect.

2. Q: What particle size of coarse stones can this equipment handle? 

A: It adapts to various conventional coarse stone particles for industrial construction, covering most coarse aggregate specifications required by engineering projects.

3. Q: Is the equipment easy to block during continuous coarse stone processing? 

A: The widened cavity and anti-blockage structural design greatly reduce blocking probability, supporting long-term continuous batch processing of coarse stones.

4. Q: Will the washing process damage the complete shape of coarse stones? 

A: The equipment adopts mild and powerful stirring mode, which only removes surface impurities without crushing or damaging coarse stone particles, ensuring complete aggregate gradation.

5. Q: Can EPIC adjust the equipment according to my material conditions? 

A: Yes, we can optimize spiral pitch, water flow and cavity structure according to your coarse stone particle size and mud content to achieve the best washing effect.

6. Q: What after-sales support can be obtained for coarse stone washing equipment? 

A: We provide global on-site installation, commissioning, staff training and long-term spare parts supply services to ensure stable equipment operation.
