Operation of the Suction System during the Production of a Mixture of Polypropylene and Polyethene Granulate from the Point of View of the Risk of Possible Fire and Explosion of Combustible Dust

Abstract

This article deals with the operation of the suction system with the risk of fire and subsequent explosion of combustible dust during the operation of screw extruders and their equipment. Machines process a mixture of polyethylene and polypropylene to a granular form. It describes the suction device from the suction attachments to the separator at the selected workplace and points out specific technological problems of the device, together with measures for its solution.
