TECHNICAL SPECIFICATION
Ref: 1300 WET PAN MILL

Model 1300 Wet Disc Grinder
The 1300 Wet Disc Grinder, also known as gold wet pan mill, is a heavy-duty mineral grinding machine specially engineered for gold ore processing. Different from ordinary crushing equipment, this disc grinder adopts wet grinding technology to crush, squeeze and refine raw gold ore through two

The 1300 Wet Pan Mill is a classical heavy-duty gold grinding machine specially designed for alluvial gold, vein gold, and tailings reprocessing. Optimized with thickened casting roller and pan body, this machine features strong compression resistance, extreme wear resistance, and stable running performance. It is the most cost-effective mineral grinding equipment for small and medium gold mines in Africa, South America and Southeast Asia.

Heavy-duty Wear Parts: The grinding roller and grinding pan adopt high-manganese chromium alloy casting, service life increased by 35% compared with ordinary cast iron.
Enhanced Transmission System: Reinforced gearbox with thickened driving shaft, no slipping under heavy ore load.
High Gold Recovery Rate: Wet grinding without dust loss; gold monomer dissociation rate ≥98%, perfectly matched with mercury amalgamation and sluice box.
Low Maintenance Cost: Integrated welded base, stable operation, fewer vulnerable parts, simple daily lubrication maintenance.
Wide Compatibility: Suitable for quartz gold ore, rock gold ore, silver, copper, manganese and other non-ferrous metal mineral grinding.
After the motor drives the reducer, the two heavy grinding rollers rotate circumferentially along the grinding pan. The ore materials are continuously squeezed, crushed, rubbed and refined under the gravity pressure of the rollers. The coarse gold-bearing ore is dissociated into fine granular pulp. Finally, pure gold is separated through gravity separation or amalgamation process.
Widely used in small and medium mining sites, especially for rock gold, alluvial gold grinding, tailings reprocessing. It is the mainstream mineral processing equipment in Africa, Sudan, Ghana, Tanzania and other gold mining areas.
