PREDICTION OF PARTICLE SIZE DISTRIBUTION OF A BALL

2021-12-2  In the mining industry, it is important to minimize the wastage of raw materials while achieving the desired particle size distribution by grinding the original input mix. To date, the procedure is performed manually, and there is no such control mechanism for grinding that reduces wastage to achieve the desired output, resulting in the loss of material.
