Nov 18, 2014· Slide 2 Content Introduction Circulating load calculate Most factories the purpose of control Effective factors for circulating load Test design Conclusion References 3. Slide 3 circulating load ratio : As the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit.Circulating Load Calculation Formula,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

Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or

Circulating Load Calculation In Secondary Crushing Circuit. Circulating load calculation in secondary crushing circuitirculating load calculation in secondary crushing circuitcirculating load ratio scribd circulating load ratio clr is defined as the ratio of the amount of solids going alculated should determine the number of Use Of A Simplified Method To Calculate Closed CrushingCyclones Don’t Do Any Grinding Blog Orway Mineral,If the circulating load decreases, the cyclone feed density decreases and a finer product size is produced. The circuit is self-compensating and thereby prevents rapid changes in circulating load. In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate.

Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).Definition Closed Circuit In Mineral Processing,Definition of circulating load mindat glossary.
