The ball grinding mill is used in fertilizer production to reduce various raw materials into fine, uniform powder. Designed as a grate-type ball mill with two-chambers, it delivers stable operation, reliable performance, and high grinding efficiency over long-term use.

The mill consists of a feeding section, discharge section, rotating cylinder, and drive system. The drive unit includes a motor, reducer, small gear, and electrical control system to ensure smooth and controlled operation. The hollow shaft and internal lining plates are made from wear-resistant cast steel and are detachable, making inspection and replacement straightforward. The optimized cylinder structure and abrasion-resistant liners support consistent grinding performance and extended service life.

The ball mill is used to grind raw materials into fine powder as a pre-treatment step before drying and screening. By stabilizing particle size distribution, it helps maintain consistency in downstream processes and supports line upgrades or capacity expansion for compound and granular fertilizer production.
