Grindability Index Ball Mill Bond Work Index Ball Mill
1.Description:
The fineness index of grinding is an index indicating the grindability of cement raw materials and their mixtures. The principle of its measurement method is to grind the materials in a specified grinding machine until a balanced state is reached. Then, the fineness index is calculated based on the amount of finished product generated by the grinding machine per revolution, and it is used to represent the difficulty of grinding the materials. This ball mill is the key instrument and equipment for measuring the fineness index, also known as the Bond Fineness Index Mill. It is widely used in teaching and research departments for testing the grindability of cement raw materials and mixtures.
