The inner and outer surfaces as well as edges of the 500ML ball mill jar have been polished, resulting in a smooth, glossy, thick, and durable surface. It also has strong corrosion resistance, high temperature resistance, anti sinking bottom, and anti adhesion properties. This ball mill jar is one of the commonly used grinding accessories for laboratory planetary ball mills.

The choice of material for the ball mill jar mainly depends on the properties of the ground sample and the requirements for the discharge particle size. The hardness of the sample must be lower than that of the ball mill jar and the grinding ball, and the material of the ball mill jar and the grinding ball is also the same. Therefore, it is recommended to choose the same material as much as possible when selecting the ball mill jar and the grinding ball. If the hardness of the sample is higher than that of the ball mill jar and the grinding ball, it will wear down the ball mill jar and the grinding ball, and the sample cannot achieve the crushing effect. Moreover, the wear of the ball mill jar and the grinding ball will cause contamination of the sample.
