Planetary Ball Mill BM20Plus is 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 reproduc- ible. Apart from the classical mixing and size reduction processes,the mills also meet all the technical requirements for colloidal grinding.

Product Details

Applications

Sample Type: soft,hard,brittle, fibrous
Application Field: engineering / electronics, building materials, agriculture, medicine, chemi- cal/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, kaoin, bones, metal oxide, iron ore, ceramics, polymers, bentonite/bentonite, pigment, and so on.

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.

Speed Ratio Is Customizable
The planetary ball mill BM20Plus have 2 grinding stations. The parameter can be set according to the sample property freely. Wide kinds and high quality grinding materials are available for choice. Grinding balls of different quantities and sizes can be combined flexibly to meet personalized special crushing and grinding requirements. When the planetary ball mill is in operation, extremely high impact energy are produced between the grind- ing balls and the grinding jars, so it can finish the grinding of the sample in a very short time. The working principle of the planetary ball mill is based on the relative rotation of the sun wheel and the grinding jar. The speed ratio influences the input energy and results of grinding directly. We can customize the speed ratio from 1:1 to 1:-3.5 as customer requirements.

Features And Advantages

Automatic direction reversal to avoid agglomerations Powerful and quick grinding down to nano fineness Suitable for long-term and continuous operation
Reproducible results due to program grinding parameters

Control Panel
The LED display shows the parameter digitally. The running state could be observed easily
BM20Plus with a comfortable parameter setting and ergonomic 1-button operation

Comfortable operation and easy cleaning
O The intelligent security lock ensures the safety of the instrument operating.
O The planetary ball mill ergonomically designed, which integrates comfort and safety in operation.
O The humanized program design can set the grinding time, and can operatewithout the need of personnel monitoring.
O Efficient, maintenance-free drive is used for planetary ball mill, so as 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 .

Pressure And Temperature Measuring System PTM
During the operation of planetary ball mill, the process and reactions (such as temperature, pressure change, etc.) take place in the grinding jars could be monitored and recorded by the PTM to achieve better grinding and analysis results.

Grinding jar's feature
O Capacity and material are marked on the grinding jars ,which is easy to distinguish from others.

O Wide kinds of materials to meet different treatment requirements.

O The O-ring guarantees dust -prevention, pressure tight.
O It's easy to open the jars by the gap, which exist between the grinding jar and lid.
O Grinding jars of agate, sintered aluminum oxide, zirconium oxide and tungsten carbide are coated with stainless steel jacket.
