Bond Work Index Ball Mill

DESCRIPTION

The Bond Work Index Ball Mill is a high-performance mill designed to measure the grindability of materials and conduct Bond Work Index tests. Suitable for both wet and dry grinding, this mill can be used not only for Bond Work Index determinations but also as a general-purpose ball mill, with a 22-liter capacity providing versatility across various material types in laboratory studies and grinding applications.

  • Ideal for Bond Work Index Tests: Provides an ideal solution for Bond Work Index tests, essential for measuring the grindability of various materials.
  • Mill Speed: Infinitely adjustable speed with a speed controller allows for precise rotation adjustment from 0 to 100 rpm, creating suitable grinding conditions for different materials.
  • Mill Structure: The cylindrical mill tube, with internal dimensions of Ø305×305 mm (Ø12″×12″), is made of stainless steel (AISI 304), enhancing durability and ease of cleaning.
  • Grinding Balls: Supplied with a charge of hardened, heat-treated chrome alloy grinding balls, delivering high efficiency and durability for size reduction.
  • Collection and Separation Chamber: Equipped with a product collection and ball separation chamber, making collection and separation simple after grinding.
  • Digital Timer: The adjustable digital timer (0-9999 revolutions) enables precise timing control, allowing easy selection of the desired grinding duration for each operation.

These features and advantages make the Bond Work Index Ball Mill an excellent solution for laboratory and small-scale production applications, offering high efficiency and flexibility in sample preparation and size reduction processes.

Quiet Operation: Acoustic foam lining reduces noise, providing a quieter and more comfortable working environment.
Efficiency in Sample Preparation and Size Reduction: Hardened chrome alloy grinding balls offer high efficiency and durability, particularly beneficial for repeated sample preparation and size reduction.

Versatile Grinding Capability: Performs both wet and dry grinding, meeting a variety of grinding needs.

Durable and Easy-to-Clean Structure: Stainless steel mill tube enhances durability and is easy to clean, ensuring a longer lifespan and ease of maintenance.

The lid safety switch, designed to prevent operation while the lid is open, ensures the highest level of operational safety. This safety system prevents the mill from functioning as long as the lid remains open, thereby avoiding potential accidents. The motor will not activate, and the grinding process cannot begin until the operator secures the lid. This feature is crucial for both operator safety and the safe operation of the mill.

APPLICATION AREAS

Our Bond Mill is suitable for grinding a wide range of materials. Some uses include:

Mineral ores (copper, iron, gold, chrome ores), concrete, ceramics, coal, glass, quartz, corundum, granite, slag and cement clinker, some industrial wastes, etc.

Working Principle

Material Placement: The material to be ground is placed in the mill tube, which is filled with hardened, heat-treated chrome alloy grinding balls.

Ball Movement: When the machine is activated, the balls begin to move within the tube. This motion leads to continuous interaction between the balls and the material, resulting in material fragmentation.

Mechanical Collisions: The balls strike the material, creating high-energy mechanical impacts. These collisions crush and reduce the material in size, and the continuous movement of the balls grinds the material uniformly into the desired fine powder.

Grinding Time and Speed Adjustment: The mill’s rotation speed can be adjusted with the speed controller. The user can seamlessly adjust the rotation speed from 0 to 100 rpm based on the material properties and desired grinding outcome.

Collection of Results: Once the grinding process is complete, the ground material is collected from the mill’s output section, ready for analysis and other processes.
