1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding 0.25 wt.% of the feed) during grinding,, .The use of grinding aids to increase mill throughput is quite common in the cement industry,, .
grinding machine gage is usually the incoming air pressure, which is not necessarily equal to the pressure of the specimens against the platen. Perforated or grooved platens are available that aid in the re-moval of swarf.
