Utilization of wastes/by-products as a grinding additive

In this work, the use of water (W) as a grinding additive in addition to waste/by-products such as olive black water (BW) and residue of olive black water (RBW) in calcite dry grinding to be sized in microns was investigated at a laboratory scale. The test results were evaluated based on product fineness, grinding time, liquid material dosage, and powder flowability. The study revealed that the use of any kind of liquid materials tested improved the grinding process compared to the blank condition. Considering RBW, powder flowability increased as its concentration increased. The findings from both the BW and W data revealed that the dose increase does not yield favorable outcomes in relation to the ffp index. Nevertheless, there was a noticeable enhancement in particle fineness.
