Increase throughput

Pushing the plant to the limit in terms of throughput demands the elimination of all sources of inefficiency. For the cement finishing circuit an imprecisely defined and/or unnecessarily fine set-point are usually the major problems, since these lead to over-grinding. However, time is also lost through poor control during transient operations (start-up and product changeover) and when process upsets are not rapidly detected.

Laser diffraction particle size data enable the more precise setting of fineness specifications for the final product since they correlate more sensitively with product performance than do Blaine measurements. Furthermore, real-time continuous size analysis allows instant observation of the results of process actions, enhancing the effectiveness of manual control and offering a route to automation. With on-line analysis in place:

Control is improved minimizing over-grinding

Moving to a new set-point is much easier, cutting changeover times

Process insight is maximized and upsets are instantly detected

In combination these benefits de-bottleneck the unit maximizing throughput within the constraints of the hardware.
