The Overflow Type Ball Mill manufactured by Zhengzhou Zhenggang Machinery Co., Ltd. is mainly used for grinding operations in metal ore beneficiation, building materials, cement, chemical, refractory, glass ceramics, and mineral processing industries. Unlike grate type ball mills, this mill discharges materials naturally through overflow instead of a grid plate, making it especially suitable for fine grinding and secondary grinding circuits. The mill consists of a feeding part, discharging part, rotating cylinder, transmission system, liners, and grinding media. With stable operation, replaceable wear-resistant liners, smooth discharge, uniform particle size, low noise, and wet or dry grinding capability, the Overflow Type Ball Mill is ideal for applications requiring fine and consistent grinding results.
The overflow discharge design allows ground materials to flow out naturally, making it suitable for fine grinding and secondary grinding processes.
Stable overflow discharge helps produce fine and uniform particle distribution for beneficiation and powder processing applications.
The corrugated liner in the fine grinding zone improves lifting performance and grinding efficiency while reducing energy consumption.
High-precision rolling bearings and optimized transmission design support smooth, reliable, and quieter operation.
The simple structure allows convenient inspection, quick liner replacement, and reduced maintenance workload
The machine can be used for both dry powder grinding and wet slurry grinding according to production requirements.
Used for fine grinding of ferrous and non-ferrous metal ores in mineral processing plants.
Suitable for secondary-stage grinding where finer particle size and stable discharge are required.
Applied in cement plants for grinding clinker and related cement raw materials.
Used for fine grinding of chemical materials, refractory materials, and industrial minerals.
Suitable for powder processing in glass ceramics, building materials, and related industrial production lines.
Used for secondary grinding and regrinding of mineral concentrates where fine particle size, uniform discharge, and stable beneficiation performance are required.
