Batch Ball Mill

The Batch Ball Mill is a grinding equipment widely used for laboratory R&D, pilot-scale testing, and small-batch production. Operating in a batch mode, it loads material and grinding media (e.g., steel balls) into a sealed grinding chamber. The rotation of the chamber causes the materials to be pulverized to a superfine state through impact and abrasion.

Diameter:600-3200 mm

Power:2.2-75 kW

Capacity:0.05-15 t/batch

Product Details

Introduction：The Batch Ball Mill is a grinding equipment widely used for laboratory R&D, pilot-scale testing, and small-batch production. Operating in a batch mode, it loads material and grinding media (e.g., steel balls) into a sealed grinding chamber. The rotation of the chamber causes the materials to be pulverized to a superfine state through impact and abrasion. Known for its operational flexibility, adjustable product fineness, ease of cleaning, and quick material changeover, it is the ideal solution for scientific research, quality control, and small-scale precision processing.
Working Principle：Material, together with a specified quantity and size of grinding media, is loaded into a rotating drum lined with wear-resistant material. As the drum rotates around its horizontal axis, the grinding media are lifted to a certain height by friction and centrifugal force before cascading or cataracting down. During this process, the media exert intense impact and abrasive forces on the material. Through continuous collision, compression, and shearing, the material is progressively crushed and refined. The mill stops after a preset grinding time, and the product meeting the target fineness is discharged, completing one working cycle.

Product Advantage

Flexible & Precise Control – Enables precise control over grinding time, media composition, and rotational speed for each batch, ensuring consistent product fineness and high repeatability between batches.
Easy Cleaning & Material Changeover – The batch operation design allows for thorough cleaning of the grinding chamber, completely preventing cross-contamination between different materials. It is ideal for processing multiple materials or applications requiring high purity.
Lower Capital & Operational Cost – Relatively simple structure eliminates the need for complex ancillary systems like continuous feeding, classification, and dust collection. It has a small footprint and lower initial investment and energy consumption.
High Adaptability – Suitable for both dry and wet grinding processes. It can handle a wide range of materials from soft to medium-hard, making it versatile for minerals, chemicals, ceramics, pigments, new materials, and more.
Easy Maintenance – Robust and reliable design with easy access to key components for inspection and maintenance, effectively reducing long-term operating costs.
