what is circulating load in ball mill

  • Ball Mill Circulating Load Mineral Processing & Metallurgy

    Oct 09, 2015· The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding.Circulating Load Calculation Formula,Feb 21, 2015· In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent.

  • Circulating Load Equation Grinding & Classification

    The usual definition of a circulating load is the (dry) mass flow returning to the mill from the classifier and is expressed as a percentage of the mass flow of new feed (Wills Min. Proc. Technology, 2016)High recirculating loads in Ball Mill Circuits Grinding,The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron.

  • High recirculating loads in Ball Mill Circuits Grinding

    Actually with the re-circulating load of about 250-300%, your operations are fine on the ball mills. You only experience high re-circulating loads if there is a change in the material being treated meaning the Bond work index tends to be higher for the new material.A guide to maximising ball mill circuit classification,circulating load is very low for a ball mill circuit, causing a very high reduction ratio through the mill in a single . pass, the arithmetic average method should be substituted with a better approximation of the size distribution gradient from feed to discharge (such as a first

  • (PDF) Circulating load calculation in grinding circuits

    An industrial ball mill operating in closed–circuit with hydrocyclones was studied by five sampling surveys. The calculated results show that the circulating load larger than 3 has noCirculating load calculation in mineral processing closed,Jan 01, 2013· A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

  • Grinding Circuit Overload Grinding & Classification

    If you need to add water to the feed end of your ball mill to control the density, by all means do so, but make sure you decrease water addition by an equal or greater amount elsewhere in the circuit (e.g. SAG feed or cyclone feed) or the overload will continue to escalate once the immediate benefits are overtaken by increased circulating load.circulating load equation,Circulating Load Ball Mill.
