Planetary Ball Mill
Planetary Ball Mills are ideal for grinding (dry or wet) and blending various types of soft, hard, brittle, and fibrous samples. They are utilized wherever customers demand the utmost level of precision, and where consistent grinding results are essential.
In addition to the traditional functions of mixing and reducing particle size, these mills also fulfill all the necessary technical criteria for achieving colloidal grinding.
Sample Types: Soft, hard, brittle, fibrous
Application Fields: Engineering/electronics, building materials, agriculture, medicine, chemical/synthetic materials, geology/metallurgy, environment/resource recovery, glass/ceramics
Typical Samples: 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, kaolin, bones, metal oxide, iron ore, ceramics, polymers, bentonite, pigment, and so on.

When the planetary ball mill is initiated, the motor propels the central sun wheel into motion, and the grinding jars, situated on the sun wheel, revolve about their individual axes. The direction of the sun wheel's motion is opposite to that of the grinding jars in a 1:2 ratio. Inside the grinding jars, the grinding balls experience superimposed rotational motion, often referred to as Coriolis forces.
This interaction results in the release of significant dynamic energies by the grinding balls. The samples continually encounter impacts from the grinding balls and are rapidly crushed due to the friction against the inner wall of the grinding jar.
- Automatic Direction Reversal to Prevent Agglomerations: The system automatically changes direction to prevent clumping.
- Powerful and Rapid Grinding to Nano Fineness: Achieves quick and powerful grinding down to nano-sized particles.
- Suitable for Long-Term and Continuous Operation: Designed for extended and continuous use.
- Reproducible Results Thanks to Programmed Grinding Parameters: Consistent outcomes are ensured through programmed grinding parameters.
- Grinding Chamber with Automatic Ventilation System: The grinding jar is equipped with an automatic ventilation system for cooling.
- Four Grinding Platforms for Simultaneous Processing: With four grinding platforms, it can process 2, 4, or 8 samples simultaneously (BM40 model).
- Six Varieties of Grinding Jars in Different Materials: Six types of grinding jars are available, with volumes ranging from 12ml to 4000ml.
Customizable Speed Ratio
Planetary ball mills offer the option of 1, 2, or 4 grinding stations. This parameter can be adjusted freely to suit the sample's specific characteristics. You have a wide selection of high-quality grinding materials to choose from. Furthermore, grinding balls of various quantities and sizes can be flexibly combined to meet unique crushing and grinding needs.
During the operation of the planetary ball mill, it generates an extremely high level of impact energy between the grinding balls and the grinding jars, allowing it to complete the sample grinding in a very short duration.
The fundamental principle of the planetary ball mill hinges on the relative rotation of the sun wheel and the grinding jar. The speed ratio directly affects the input energy and the grinding outcomes. As per customer requirements, we can customize the speed ratio from 1:1 to 1:-3.5.
