The 1224 ball mill is a core piece of gold ore processing equipment. The choice of dry or wet process directly impacts beneficiation efficiency and economic benefits. Dry grinding utilizes airflow discharge technology, eliminating the need for liquid media, making it suitable for arid regions or where direct dry powder production is desired. Wet grinding, on the other hand, uses water to create a slurry, leveraging the lubricating effect of the liquid to improve grinding uniformity. The two processes differ significantly in their equipment structure: dry ball mills are equipped with induced draft devices and dust removal systems, and feature a straight cylindrical discharge port. Wet ball mills utilize a spiral discharge mechanism and a trumpet-shaped discharge port to facilitate slurry flow. For gold ore processing, wet processes generally achieve higher metal recovery rates but require supporting tailings treatment facilities. While dry processes conserve water resources, they can increase environmental costs due to dust. This fundamental difference requires comprehensive consideration of multiple factors, including ore characteristics, geographical environment, and subsequent beneficiation processes, when selecting a process.

When processing gold ore in a 1224 ball mill, the wet process demonstrates significant technical advantages. Its core value lies in the slurry environment created by the water medium, which effectively encapsulates gold particles and reduces oxidation losses during grinding. The lubricating effect of the liquid also enhances contact efficiency between the steel balls and the ore, increasing the degree of gold dissociation by 15%-20%. Especially for fine-grained disseminated gold ores, wet grinding combined with a spiral classifier in a closed-circuit process can stably control ore fineness to below 0.074mm, meeting the monomer dissociation requirements of flotation. Actual application cases show that gold recovery rates in concentrators using wet grinding are generally 3-5 percentage points higher than those of dry grinding, while grinding energy consumption is reduced by approximately 12%. This process can also optimize grinding performance by adjusting the slurry concentration (typically controlled at 65%-75%), preventing gold loss due to mudification caused by over-grinding. It is worth noting that wet grinding places higher demands on equipment wear resistance, requiring the use of high-chromium alloy or rubber liners to combat slurry corrosion. However, long-term operating costs are still lower than the dust removal and maintenance costs of dry grinding.
