The client sourced a Vortex Orifice Gate for use on a carbon black extrusion line. In order to create plastic pellet, the client fills a bag dump station with carbon black. Once the bag dump station is filled, the lid is closed to seal off the station. The carbon black is then mixed into other plastic ingredients and heat is applied to form a plastics mixture. Once finished, the mixture is fed through an extrusion line using the Orifice Gate, which is situated below the bag dump station.
