Planetary Ball Mill, PBM-G Series

Description

Planetary Ball Mills are suitable for grinding (wet/dry) and mixing a wide range of soft, hard, brittle and fibrous samples. In addition to classical mixing and particle size reduction processes, the mills can also meet the technical requirements of colloid grinding.

Applications

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.

• Grinding chamber automatic ventilation system for cooling the grinding jar.
• With 4 grinding platforms can process 2,4,8 samples simultaneously (PBM-G40).
• 6 kinds of grinding jars in material ,the volume various from 12ml-4000m

Features

Customizable speed ratio

• The planetary ball mils have 1,2 and 4 grinding stations as option, The parameter canbe 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.
• We can customize the speed ratio from 1:1 to 1:-3.5 as customer requirements.

Control panel

• The LED display shows the parameters digitally, and the running state can be observed easily.
• Equipped with convenient parameter settings and ergonomic one-button operation.

Comfortable operation and easy cleaning

• Intelligent safety lock ensures safe operation of the instrument.
• Ergonomic design integrates comfort and safety in operation.
• The humanized program design can set the grinding time, and can operate without the need of personnel monitoring.
• The high-efficiency, maintenance-free drive ensures that the machine can maintain a constant speed during long-term continuous operation or maximum overload. During the grinding process, the built-in high-power fan can automatically provide effective cooling for the motor.

Jar-opening tools

The user-friendly design makes the jar opening work more easy and safe.

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 safe operating.
• Safety closure device can be sealed in colloid grinding (wet grinding) to ensure the over pressure gas not easily escape.
• Aeration lid for gas importing, exporting as well as for safety protection.
• The safe closure devices 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.

Grinding jar

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