Grinding mills are key equipment for further pulverizing materials after crushing. There are many types, such as ball mills, rod mills, vertical mills, autogenous mills, and ultrafine grinding equipment.
To distinguish them from autogenous mills, grinding mills requiring metal media balls or rods are typically called conventional grinding mills, such as ball mills and rod mills.
Ball mills are further categorized into grate-type ball mills and overflow-type ball mills. Grate-type ball mills enable low-level forced discharge, preventing finely ground particles from lingering excessively within the mill. This promptly eliminates over-grinding, resulting in rapid grinding speeds and high efficiency. Overflow ball mills feature an inclined discharge end. When the pulp level rises above the discharge opening’s inner diameter, the pulp overflows and discharges. This design results in slower discharge rates, severe over-grinding, and lower throughput. Consequently, overflow ball mills are generally used for fine grinding or as the second stage in two-stage grinding processes.

Gold flotation production line is a production line used for gold ore dressing, which is often used to process sulfide mineral gold-containing ores with high floatability. Gold minerals are mainly separated from ores through flotation process. The cost of mineral processing is low, and 80% of rock gold mines in my country are separated by this process.
The magnetite beneficiation process is mainly used to select low-grade magnetite. Since the ore has strong magnetism and is easy to grind and select, the coarse-grained magnetite is mostly ground at the current stage, and vice versa, a multi-stage grinding process is used.
Fluorite ore beneficiation methods include gravity separation and flotation, which are also divided into gravity separation equipment and flotation equipment. Gravity separation equipment refers to jigs, and only jigs can process coarse-grained fluorite lumps. Fluorite flotation equipment is similar to other mineral flotation equipment, including crushers, ball mills, flotation machines, etc.
