Get PriceMay 28, 2020 Based on the PSD and RT of the blend in the BBM, the minimum grinding time of the blend sample was determined by reducing the grinding time in the LBM at regular intervals. The grinding time of the LBM was set by reducing the total RT taken by the blend to get ground in the BBM, since the BBM produces very fine particles for 250 circulating load.
