Introduction：A drum stone washer primarily consists of a drum, a drive system (motor + reducer + gears), wear-resistant lining, a support pulley, and a water supply unit. It comes in two types: 1. Drum type: a basic model focused on desludging and cleaning; 2. Drum with screen grate type: an additional grading function, capable of outputting products in two grades: +40mm and -40mm. The -40mm material can be further processed by a spiral washer to ±2mm.
Working Principe：1. Feeding and Rotary Dropping: Mud-laden material enters the slow-rotating drum through the feed inlet and is repeatedly lifted and dropped by the inclined wear-resistant lining inside, removing surface impurities through friction. 2. Hydraulic Flushing: High-pressure water (forward/reverse) sprays the material, creating a vortex that removes the mud. The wastewater is discharged through holes in the drum or an overflow outlet to a sedimentation tank for reuse. 3. Grading and Discharge: Clean ore moves to the discharge end, where it is dewatered by a drum screen before being discharged. Screen grate models also perform particle size classification (e.g., ±40mm).
