1290 K. Tsakalakis In the reverse or indirect crushing circuit the equations giving the circulating load Rv are functions: • of E, t, u, (Karra, 1979), where t, u are the undersize contents in ...
To address the abovementioned control problems, a mass balance controller was implemented to the tertiary crushing circuit. The control objective was to stabilize the ratio between fresh feed and circulating load and to be able to respond rapid throughput changes. This was necessary to avoid disturbance generation to the size reduction …

The well-known formulae of screening efficiency and circulating load calculations in closed crushing circuits were exploited to achieve graphical estimation of these parameters. Three basic charts were proposed and constructed. The first one is for the regular closed circuits where the new feed goes to the crusher. The second is for the …
The use of these nomographs facilitates calculations of circulating load and screen efficiency (undersize recovery). They can be used for the selection of crushing and sizing equipment. The procedure gives accurate and simple prediction of the circulating load without knowing any of the initially proposed equations.
CIRCULATING LOAD: These calculations of the percent circulating load are based on two methods: 1) Percent solid or pulp densities around the cyclone. 2) Percent passing a …

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 ratios and circulating load tonnage on tons/day or tons/hour.
