Planetary ball mill BM6Pro

Planetary Ball Mill BM6Pro is suitable for grinding (dry\wet) and mixing some soft, hard, brittle and fibrous samples, which is used wherever the highest degree of fineness as customer required,as well as the grinding result is reproducible. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding.

Application

• Sample type: soft, hard, brittle, fibrous;
  
• Application field: 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, 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 have 1 grinding station. 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 grinding 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.

Multi-safety design of grinding jars

• For colloid grinding, the grinding jars are equipped with safe closure device for gas-tight and dust-proof to ensure operating;
• Safety closure device can be sealed in colloid grinding (wet grinding) to ensure the overpressure gas not easily escape;
• Aeration lid for gas importing, exporting as well as for safety protection;
• The safe closure device can guarantee the high-level gas tightness inside grinding jars so as to ensure that the grinding result is not affected;

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.

Features and advantages

• Comfortable operation and easy cleaning;
  
• Automatic direction reversal to avoid agglomerations;
• Powerful and quick grinding down to nano fineness;
• Suitable for long-term and continuous operation;
