  • 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

  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    2/8/2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

    Clamp load is typically around 75% of a bolt’s proof load; that is, the highest stress the bolt can accommodate before experiencing plastic deformation. The proof load itself is usually 85% to 95% of a bolt’s yield strength, but the clamp load is significant because it is what ultimately provides the clamping pressure. Once the clamp load is determined, finding the correct torque value for
