摘要

The paper focusses on improving the energy utilization of a cement grinding circuit by changing the flow sheet of the process. The circuit was comprised of ball mill, static classifier and dynamic classifier and in the current flow sheet the fine product of static classifier is sent to feed stream of dynamic classifier. However, it was experimentally proved that sending static fine to the final product silo had several benefits. In order to quantify the benefits, 250 kg of static fine stream was collected then mixed with the final product and series of tests i.e., compressive strength, particle size, chemical assays and water demand, were undertaken. The results showed that mixing static fine with final product increased the 28-day strength by 23%, 4.3% and 4.8% for CEM I, CEM II and CEM IV type cements respectively. Improved strength results were attributed to having wider size distributed product (reduced slope value) that decreased the water demand of the cement. Such an increase in strength enabled to coarsen the final product at the same quality figures. Therefore, in the next phase of the study, the grinding circuit was simulated as the static fine stream would be sent to final product silo that indicated the production rates of the circuit could be increased by 9.7% for CEM II, 7.4% for both CEM I and CEM IV types.
