The name “spiral sand washing machine” itself suggests its operation. Like any piece of equipment, the spiral stone washing machine has its standard operating procedures. Adhering to these procedures is crucial. During production, the tension of the motor-driven belt should be moderate to ensure both output and quality. The impeller device of the spiral stone washing machine effectively controls the vortex rotation and speed of the material within the crushing chamber, reducing wear and tear and improving production efficiency. The high-performance impeller and highly wear-resistant liner structure significantly extend the machine’s lifespan and enhance its working efficiency.

During operation, the impeller, driven by a belt-driven motor and gear reducer, slowly rotates. Sand and gravel move from the feed tank to the washing tank. The roller-driven impeller grinds the sand and gravel against each other, removing impurities from the gravel surface and damaging the steam-coated sand layer to promote dehydration. Simultaneously, water is added, creating a strong current that drives impurities and foreign objects away from the washing tank and overflow outlet, resulting in a complete cleaning effect even with a small percentage of impurities removed. Clean gravel is discharged from the blades and impeller into the chute, providing a complete cleaning effect for the rotating gravel.
