1. Core parameter configuration of 0918 gold mine ball mill

The 0918 ball mill has a barrel diameter of 900mm and a length of 1800mm. It uses JM series manganese steel liners and is equipped with a 45kW explosion-proof motor as standard. The speed is set to 76% of the critical speed (about 28r/min). In terms of loading capacity, the steel ball filling rate is 35%-40%, the processing capacity is 0.8-2t/h (depending on the hardness of the ore), the feed particle size is ≤25mm, and the discharge fineness can be adjusted to 0.074-0.4mm. Equipped with a hydraulic jacking device and an intelligent lubrication system, the bearing temperature real-time monitoring accuracy reaches ±1℃.

2. Technical innovation highlights of 0918 gold mine ball mill

Double-bin structure design: The coarse grinding bin adopts corrugated lining to enhance impact force, and the fine grinding bin is equipped with stepped lining to enhance grinding efficiency

Various frequency control system: Energy consumption is reduced by 18% compared with traditional models, and supports 0-30r/min stepless speed regulation

Modular assembly: The basic installation cycle is shortened to 72 hours, which is particularly suitable for the rapid production needs of mining areas

3. Typical application scenarios of 0918 gold mine ball mill

This model is mainly used for:

The front-end crushing process of cyanide leaching of small and medium-sized gold mines

The combined beneficiation system of rock gold mines and placer gold mines

The secondary grinding link of the tailings reprocessing project

4. Maintenance points of 0918 gold mine ball mill

It is recommended to supplement the steel ball ratio every 400 hours, replace the liner bolt anti-loosening gasket every quarter, and the main bearing clearance should be maintained at 0.15-0.20mm. The motor insulation resistance value should be checked daily during rainy season operations.
