Abstract

A separator for separating solid particles from a processing gas stream that has been fed repeatedly through a work machine, wherein the separator includes a processing gas inlet through which particle-laden processing gas emitted from the work machine is fed into the separator, and a filterless separator element to reduce the particle content of the processing gas and a processing gas outlet to discharge the processing gas with its reduced particle content to the work machine, the separator including a secondary stream filter, which filters a smaller portion of the processing gas, and a secondary outlet, connected thereto, which ejects the filtered secondary stream of processing gas.
