1. Product Overview

The 1200 Wet Disc Grinder is a medium-sized heavy-duty mineral grinding machine, specially manufactured for coarse grinding and fine dissociation of precious metal ores. Upgraded and optimized on the basis of traditional wet pan mill, this disc grinding equipment adopts double roller pressure grinding structure and fixed disc design. Compared with ordinary crushing machines, it performs pure physical wet grinding without chemical additives. Featuring stable output, low energy consumption, compact structure and easy movement, this grinder is perfectly suitable for small and medium-scale mining sites, remote mining areas and seasonal mineral processing projects. It effectively crushes hard rock ore, dissociates monomer gold from gangue, minimizes fine gold loss during processing, and greatly improves the overall gold recovery rate.

2. Structural Design & Material Advantage

Every core wearing part of the 1200 wet disc grinder adopts high manganese chromium alloy casting, including grinding disc and two grinding rollers. This customized alloy material owns excellent hardness, compression resistance and abrasion resistance, effectively resisting strong friction and impact caused by hard ore, extending service life by more than 40% compared with ordinary cast iron. The main body frame is welded with thickened carbon steel plates, equipped with reinforced bottom support legs to reduce shaking during high-load continuous operation. The built-in heavy-duty reduction gearbox provides high torque and stable transmission; the thickened integral driving shaft is not easy to deform or break, which prevents roller slipping and material accumulation under long-term heavy ore load. All connecting parts adopt standardized disassembly structure, making daily lubrication, inspection, cleaning and vulnerable parts replacement simple and time-saving, effectively lowering long-term mining operation and maintenance costs.

3. Working Principle

Driven by a durable 15KW copper wire industrial motor, the power is stably transmitted to the gearbox and driving shaft. Two heavy self-weight grinding rollers rotate circumferentially around the fixed circular grinding disc at a constant low speed. Raw gold ore with particle size below 20mm is evenly and continuously fed into the middle grinding chamber. Relying on the self-gravity pressure of the rollers and mechanical rolling friction, the ore undergoes multiple processes including squeezing, crushing, grinding and refining. Hard rock particles are gradually ground into uniform fine pulp, which completely separates gold monomers from quartz, stone powder and other gangue minerals. The finished mineral pulp flows out from the discharge port automatically. It can be matched with amalgamation box, mercury plate, sluice box, shaking table and other gravity separation equipment to complete secondary gold separation and purification, achieving high-purity gold extraction.

4. Main Performance Characteristics

• Stable & Moderate Production Capacity: With optimized rotating speed and roller pressure, the stable hourly processing capacity reaches 2.0-2.8 tons. It supports 24-hour uninterrupted continuous operation, fully meeting daily production demands of small and medium mining plants.

• Superior Gold Recovery Performance: Fully enclosed wet grinding structure completely avoids fine gold loss caused by flying dust. The physical rolling dissociation rate of natural gold ore is up to 97%, which greatly improves the final gold output and economic benefits.

• Wide Mineral Compatibility: This grinder is not only suitable for quartz gold, vein rock gold and alluvial gold, but also applicable for tailings secondary recycling. It can process silver, copper, manganese, tin and other non-ferrous metal minerals for fine grinding.

• Energy Saving & Operational Safety: Equipped with energy-saving pure copper motor, low power consumption and low operating noise. The external protective cover and emergency stop device effectively avoid mechanical accidents, ensuring safe manual operation.

• Simple Operation & Low Threshold: Adopt pure mechanical transmission structure without complex electronic control system. One worker can complete feeding, grinding and discharging work. No professional debugging and technical training is required for novice operators.

• Anti-corrosion & Long Service Life: The internal grinding tank is treated with anti-rust and anti-corrosion coating, adapting to humid muddy water working environment. It is resistant to mineral slurry corrosion and harsh outdoor mining conditions.

5. Application Scenarios

The 1200 Wet Disc Grinder is highly adaptable to various harsh mining environments, widely applied in small fixed mines, rural scattered mining areas and mobile mineral processing stations. It has stable performance for high-hardness rock gold and low-density alluvial gold, and is extremely popular in Africa, Southeast Asia, South America and other gold-producing regions. This machine can be used independently for single grinding work. Meanwhile, it can form a complete low-cost mineral processing production line with jaw crusher, feeding conveyor, water circulation tank and shaking table. It is the most cost-effective primary grinding equipment for individual miners and small mining companies.
