Products Description
Bellian Ball Mill is the most widely used grinding equipment in mining, cement, chemical industry and other industries. It is used for grinding various ores and other materials to required fineness. Our Ball Mill adopts advanced design and manufacturing technology, with thickened steel plate cylinder, reinforced end cover and high-quality transmission system, which has strong impact resistance and long service life. It can be divided into grid type and overflow type according to the discharging method, and supports both wet and dry grinding processes.
Working Principle
The Ball Mill is a horizontal rotating cylinder, which is divided into grid type and overflow type according to the discharging method. When the cylinder rotates, the steel balls inside are lifted by the lining plate and fall down, generating strong impact and grinding force on the materials. The materials enter the cylinder from the feeding end, are continuously crushed and ground into fine powder by the steel balls. For grid type ball mill, the qualified powder is discharged through the grid plate, which has strong discharging capacity and is suitable for coarse grinding; for overflow type ball mill, the qualified powder overflows naturally from the discharging end, with uniform finished particle size, suitable for fine grinding.

Application Scenarios
Widely used in gold mines, iron mines, copper mines, lead-zinc mines, manganese mines, chrome mines and other metal mines, as well as quartz stone, feldspar, fluorite and other non-metallic mines. It is the core grinding equipment in flotation, magnetic separation, gravity separation and other mineral processing production lines, and can also be used for grinding various bulk materials in metallurgy, chemical industry, building materials and other industries.
FAQ
How to choose between grid type and overflow type ball mill?
Grid type ball mill has forced discharging function, large processing capacity, high grinding efficiency, suitable for coarse grinding (0.2-0.3mm finished particle size) and large-scale mineral processing lines; overflow type ball mill has natural overflow discharging, uniform finished particle size, no over-grinding phenomenon, suitable for fine grinding (below 0.074mm finished particle size) and high-precision mineral processing.
What is the difference between wet and dry grinding?
Wet grinding has high grinding efficiency, low dust pollution, and is suitable for most metal ore beneficiation lines; dry grinding does not need water, and is suitable for areas with water shortage, as well as rare metal ores and non-metallic ores that cannot be ground with water. We will recommend the most suitable process according to your ore properties and mineral processing flow.
What is the optimal ball loading ratio for ball mill?
The optimal ball loading ratio for ball mill is generally 30-40% of the cylinder volume. Too few steel balls will reduce the grinding efficiency, while too many steel balls will increase the energy consumption and wear of the machine. We will provide you with the optimal ball loading ratio and steel ball size distribution according to your material properties and required fineness.
Can you provide a complete mineral processing production line solution?
Yes, we can provide turnkey solutions including crushing, grinding, classification, flotation/magnetic separation, dewatering and other processes according to your ore type, grade and production capacity requirements, from design, manufacturing to installation, commissioning and operator training.
