Abstract

A centrifuging system is described in which the centrifuge is located in a container 10 which can be sealed by means of a lid. Means is provided for supplying to the container an inert gas for purging the container and centrifuge of all oxygen and other combustible gases/vapours etc. before a centrifuging action to reduce the risk of explosion during a centrifuging action. The venting gases are analysed by means 86 on an in-line basis and the centrifuging action including the supply of material to be centrifuged is inhibited until the analysis indicates the level of oxygen to be below a given concentration. A warning signal is generated in the event that the oxygen level increases above a given level during the centrifuging. An interlock may be provided to cut-off the supply of material to the centrifuge if the small positive pressure drops during centrifuging. <IMAGE>
