Mass size fractions are not conserved through grinding devices (SAG mill and ball mills). Therefore there is no mass conservation equation for size fractions around the grinding devices and consequently there is no node for grinding devices in mass size fraction networks. The same reasoning applies to Cu-by-size fractions.
Water balance (Dilution ratio) Water is used in mineral processing a. To transport solids in the circuit n Ball mills use ~35% water for milling and in the discharge water is further added for separation in solids Most flotation operations are performed in between 25 F40% solids by weight.

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ...

1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
A ball mill is operated in closed circuit with sieve bend under steady state conditions as shown in the attached diagram.The % solids in each stream are indicated.The water addition to the sump is 100 cubic metres per hr and to the mill feed is 67cubic metres per hr. Calculate mass flow of sol
Following the acquisition of grinding-circuit data at Brenda Mines Limited for simulation purposes, various methods to mass balance the circuit were evaluated. Unfortunately, different answers were obtained for different balancing methods. A data-adjustment procedure was therefore developed.
