When the laboratory drum ball mill is working, the grinding media and materials in the cylinder are raised to a certain height with the rotation of the cylinder, and fall away from the cylinder wall due to gravity and fall along a parabola. The materials are crushed under the impact of the grinding media and the friction and shear caused by the rolling and sliding of the grinding media.





Laboratory drum ball mill is an ultra-fine grinding and mixing equipment used in laboratories and small batch production. This machine is beautiful and novel, has a compact structure, is easy to operate, has high working efficiency, and has uniform grinding size. It is the preferred equipment for scientific research, teaching, testing, and production. It can be widely used in electronic materials, magnetic materials, biomedicine, ceramic glaze slurry, non-metallic minerals, metallic minerals, new materials and other industries.
