planetery_ball_grinderPlanetary Ball Grinder

Planetary Ball Mills are suitable for grinding(dry\wet) and mixing some soft, hard, brittle and fibrous samples ,which are used wherever the highest degree of fineness as customer required,as well as the grinding result is repeatable.Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding.


  • Application field

  • Sample type



Working Principle

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 ration 1:2. The grinding balls in the grinding jars are subjected to superimposed rotational 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 rapid crushed by the friction of the grinding jar's inner wall at the same time.


  • Powerful and quick grinding down to nano fineness
  • Suitable for long-term and continuous operation
  • Reproducible results due to program grinding parameters.
  • Grinding chamber automatic ventilation system for cooling the grinding jar.
  • Grinding jars have 6 kinds of material, the volume various from 12ml-500ml.
  • Automatic direction reversal to avoid agglomerations.
  • With 4 grinding platforms can process 2,4,8 samples simultaneously (BM40)
  • Speed ratio is customizable.


Comfortable operation and easy cleaning

Efficient, maintenance-free drive is used for planetary ball mill, to guarantee the machine can maintain constant speed in continuous operation for a long time or under maximum overload. During the grinding, built-in high-power fans can automatically provide effective cooling for motors.

  • The planetary ball mill is designed by ergonomics, which integrates comfort and safety in operation.
  • The intelligent security lock ensures the safety of the instrument operating.
  • The humanized program design can set the grinding time, and can operate without the need of personnel monitoring.

Grinding jar's feature

The jar's capacity and material are marked on the grinding jars,which is easy to distinguish from others.

  • Wide kinds of materials to meet different treatment requirements.
  • The O-ring can guarantee the dust -prevention.
  • It is easy to open the jars by the gap, which exacts between the grinding jars and lids.
  • Grinding jars of agate, sintered aluminum oxide, zirconium oxide and tungsten carbide are coated with stainless steel jacket.
  • Easy and safe to operating.

Mortor Grinder

A variety of scraper materials are available (polyurethane, PTFE, beech wood) to meet all application requirements. Suitable for dry,wet&cryogenic grinding.Mortar and pestle of sinter aluminum oxide/Mortar and pestle of agate/Mortar and pestle of stainless steel


The mortar grinder occupies an important post on sample preparation in laboratory. The gap between mortar and pestle, mill's pressure and the angle of scraper are all adjustable. This mill is suitable for the fine grinding of any dry samples, as well as for suspensions with different consistencies.

It is perfectly suitable for the homogenization of mortar and pestle.


Mortar Grinders are suitable for grinding hard, soft, brittle, and pasty samples.

Typical application:Soils, chemical products,medicinal herbs,yeast cell,cocoa,food, grain,oil,fruit,salt,slag,silicate,glass,ceramic and cement clinker

Working Principle

The sample enters the grinding area between the pestle and mortar via hopper and is crushed by pressure and friction. The function of the scraper is to feed the material into the area between the mortar and pestle. This forced feed ensures that the whole sample is continuously subjected to the grinding and is also intensively mixed.

Easy and safe to operate

The machine case and lid are made of hard alloy. It is easy to operate and ergonomically designed. The grinder is equipped with magnetic switch to judge whether the lid is closed or not, and the grinder only starts when lid is closed. The mechanical device parameter can be set and adjusted quickly and easily.

High sensitivity touch control LCD display

  • 5-inch LED display and touch control panel with high sensitivity
  • Energy input diagnosis can guarantee safe and reasonable operation.

Easy to clean

Easy exchange of mortar and pestle without tools after grinding and it's easy to clean the mill.
