QM-3 Grinding Power Index Ball Mill Grinding Power Index (BOD) is an index that represents the grindability of cement raw materials and their mixtures. The principle of its measurement method is that after the material is ground to equilibrium by a specified mill, the grinding power index is calculated based on the amount of finished product generated per revolution of the mill, which is used to indicate the difficulty of grinding the material
QM-3 Grinding Power Index Ball Mill

The Grinding Power Index (BOD) is an index that represents the grindability of cement raw materials and their mixtures. The principle of its measurement is that after the material is ground to equilibrium by a specified mill, the grinding power index is calculated based on the amount of finished product generated per revolution of the mill, which is used to indicate the difficulty of grinding the material. This ball mill is a key instrument and equipment for determining the grinding power index, also known as the Bond power index mill. It is widely used in teaching and research departments for testing the grindability of cement raw materials and mixtures.
The QM-3 ball mill is also suitable for fine grinding of small batch production materials in laboratories and factories in the ceramic and chemical industries. The machine consists of three parts: mechanical transmission mechanism, electrical control, and grinding volume. It has the characteristics of simple structure, reliable use, and convenient operation and maintenance.
