  • 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

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
