Year of construction: 2026, condition: new, ceramic ball mill ,Batch ball mill ,also called ceramic ball mill ,it is used for fine grinding of feldspar,quartz,clay,ore and so on.The ceramic ball mill is mainly used for material mixing, grinding,uniform product fineness,and saving power.It can be dry or wet.The machine can use different liner types according to production needs to meet different needs.The fineness of the grinding operation is controlled by the grinding time ceramic ball mill Working principle when ball mill working,steel balls inside drum will rotate with the drum to some height,and then steel balls fall down with materials to reach the point of grinding. Working Principle of Ceramic ball mill ceramic ball mill ,Intermittent ball mill grinding operation is finished in the cylinder body. When the cylinder rotates, materials ascend to a certain height and then fall along a certain path due to the balls' gravity. Two forces are generated on the balls inside. One is the force on balls through tangent direction; the other is a opposite force in the contrast to the diameter of balls, as a result of the force generated when the balls slide down. These two forces will constitute a couple for the steel balls. The balls are squeezed between the cylinder and the adjacent steel balls, so the couple can make unequal-sized friction force. The balls will orbit along with the cylinder axis and then fall down, which can produce a strong impact force on the ores in the cylinder body and, as a result, the ores will be crushed. In conclusion, the ores in the cylinder body are mainly crushed by composite effect of peeling force, impact force and extrusion force. Ceramic ball mill also named Intermittent ball mill which adopts the wet intermittent operation, is used for fine grinding and mixing the material such as feldspar, quartz, clay ceramic raw materials. The discharging and the mud size can through through 1000 sieve pore. This machine is high milling machinery, materials should be Broken in the fineness of the state into the grinding mill to get the highest efficiency and economic benefits.

Condition: new, functionality: fully functional, power: 55 kW (74.78 HP), Year of construction: 2026, Ball Mill for Powder and Mining Plant: Structure, Function, and Technical Details A ball mill is a key grinding machine widely used in mining, metallurgy, cement, chemical, and powder-making industries. It is designed to grind various ores and other materials into fine powder through impact and attrition between steel balls and the material inside a rotating cylindrical shell. In mining plants, ball mills are essential for ore beneficiation, preparing materials for flotation, magnetic separation, or leaching processes. In powder production, they ensure uniform particle size and high surface area for further processing. Working Principle The ball mill operates on a simple yet effective principle: as the cylindrical shell rotates around its horizontal axis, the grinding media (steel or ceramic balls) are lifted along the inner wall by centrifugal force and friction. When they reach a certain height, they fall freely, striking and grinding the material below. This repeated motion causes both impact and abrasion, reducing the material to the desired fineness. The grinding process can be performed in dry or wet conditions depending on the application. Structural Composition A standard ball mill consists of several main components: Feeding part: Equipped with a feeder or screw conveyor to ensure uniform material input. Discharging part: Can be grate type or overflow type, depending on the discharge method. Rotating part: The cylindrical shell made of steel plates, lined with wear-resistant liners. Transmission system: Includes motor, reducer, small transmission gear, and electrical control. Grinding media: Steel balls or ceramic balls of different diameters for efficient grinding. Cedpfx Aoq Nf U Espaehd The internal liner design and ball size distribution are optimized to achieve maximum grinding efficiency and minimal energy consumption. Technical Details Typical Specifications: Feeding size: ≤25 mm Discharge size: 0.074–0.4 mm Capacity: 0.65–615 t/h (depending on model and material hardness) Cylinder speed: 18–38 r/min Power: 18.5–4500 kW Liner material: High manganese steel, rubber, or alloy steel Grinding media load: 30–45% of cylinder volume Operating Modes: Dry grinding: Suitable for materials that must remain moisture-free, such as cement clinker, limestone, and quartz. Wet grinding: Common in ore beneficiation, where water or slurry improves grinding efficiency and particle uniformity. Application in Mining Plants In mining operations, ball mills are used after crushing to further reduce ore size and liberate valuable minerals. They are integrated into grinding circuits with classifiers, hydrocyclones, and flotation systems. The ground material is classified by size, and oversized particles are returned to the mill for regrinding. This closed-circuit system ensures consistent product fineness and efficient energy use. Common Applications: Gold, copper, iron, and zinc ore grinding Cement clinker and slag processing Silicate and ceramic powder production Coal and mineral powder preparation Conclusion A ball mill is an indispensable piece of equipment in both powder production and mining beneficiation plants. Its ability to grind materials into fine, uniform particles makes it vital for downstream processes such as flotation, sintering, and chemical reactions.
