Planetary Ball Mill
Planetary Ball Mill is designed for rapid fine crushing of soft, hard, brittle and fibrous material to end fineness <1um. It can not only perform mixing and grinding but also meet the requirements of colloid grinding. In addition, its giant energy input can meet the technical requirements of preparing alloy with the mechanical method.
Applications
soft, hard, brittle, fibrous, dry or wet sample, such as plant material, cement clinker, concrete, compost, coatings and paint, charcoal, hair, catalyst, chemicals, metal, carbon fiber, paper, fiber products, cellulose, seeds, clay minerals, coke, coal, glass, waste electronic products, mineral, ore, limestone, gypsum, quartz, kaoin, bones, metal oxide, iron ore, ceramics, polymers, bentonite, pigment, and so on.
Features
- High efficient fine grinding up to end fineness <1um
- With 4 grinding platforms can process 2,4,8 samples simultaneously (BM4)
- Grinding jars have 6 kinds of material , the volume various from 12ml-500ml
- Suitable for long-term trials and continuous use
- Reproducible results due to program grinding parameters
- Automatic direction reversal to avoid agglomerations
- Grinding chamber automatic ventilation system for grinding jar of cooling
Theory/Method
When the planetary ball mill starts, the motor drives the common sun wheel to move, while the grinding jars, which are located on the sun wheel, turning around its own axis. The direction of the movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2.2. The grinding balls in the grinding jars are subjected to superimposed rational movement, the so-called Coriolis forces. Under this interaction, the grinding balls release high dynamic energies. The samples are constantly impacted by the grinding balls and rapidly crushed by the friction of the grinding jar’s inner wall at the same time.
