Detailed Specifications for the 0930 Ball Mill for Gold Processing Plants

In small- and medium-sized gold ore beneficiation and gravity separation operations, the 0930 ball mill has become a core piece of grinding equipment for many processing plants due to its cost-effectiveness, practicality, and stable, efficient performance. This model features a shell diameter of 900 mm and an effective grinding length of 3 meters; with a total weight of approximately 6.8 to 7 tons and a compact footprint, it is ideally suited for small processing plants or laboratories with limited space.

Regarding power and transmission, the 0930 ball mill is typically equipped with an 18.5–22 kW motor and a reducer (such as the ZD30 or ZOZ model), maintaining a steady shell rotation speed of around 36 rpm. This power configuration ensures smooth operation even under significant impact loads while keeping energy consumption relatively low. In terms of feed and discharge specifications, the maximum allowable feed particle size is generally 20 mm or less (approx. 1–2 cm); the discharge particle size can be flexibly controlled between 0.075 and 0.89 mm (approx. 40–200 mesh) after grinding, fully meeting the fineness requirements for mineral liberation prior to beneficiation.

In terms of production capacity, the 0930 ball mill typically yields 1 to 4 tons per hour, with the exact figure depending on ore hardness and grinding slurry concentration. For small gold processing plants with a daily throughput of several dozen tons, a wet-type 0930 ball mill equipped with a 22 kW motor and wear-resistant manganese steel liners is recommended. Wet grinding not only effectively suppresses dust but also leverages the lubricating properties of water to enhance grinding efficiency, ensuring high recovery rates in subsequent flotation or gravity separation processes—making it an ideal choice that balances cost and performance.
