· The circulating load could be obtained by measuring the particle size distribution of the feed, the product and the reject, and by then using the Koulen method. (see this post ) The material M accumulated within the mill could be observed by measuring the level of the material within the mill, deducting the volume occupied by the balls and assuming a reasonable value

Natasha Chandri Egieara. Mineral Processing. 1306436741. Circulating Load Ratio. Circulating load ratio (CLR) is defined as the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Therefore, the value calculated should determine the number of passes through the mill needed to generate the total amount of new
