Improvement of Productivity Using Tromp Curve Measurement for Cement
circulation load is the average number of times that the material circulates through the circuit before becoming the product. A harder clinker will yield a higher circulation load. It is defined by the ratio of the mill's throughput, 1, to the product flow rate, 3. The circulating factor is the quantity of the separator rejects, 2Re: VRM and ball mill circulating load. Mainly in USA,the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH .Normal range of cirulating load in a conventional close circuit ball mill isVRM and ball mill circulating load International Cement Review

Effects of bypass system on PCDD/F emission and chlorine circulation in
A bypass at the kiln inlet allows the effective reduction of alkali chloride cycles and thus perhaps affects the emission of PCDD/Fs. Effects of bypass system on PCDD/F emission and chlorine circulation were studied in two typical dry cement kilns with 5000 ton/day clinker capacity in China and named CK1 and CK2, respectively. To illustrate this point, PSDs of two cements with very similar Blaine fineness (330 and 335 m2/kg) are compared in Fig. 1. The powder from Mill A is somewhat finer and has a broader PSD than the powder from Mill B. The greater fraction of particles in the size range of 2 to 10 µm makes the cement from Mill A have a water demand that is 10 L/m3A contribution from ACI Committee 236 Virtual Testing in a Cement
