Break and Feed Cylinder Systems

BreakFeedCylinderSystems CrustBreakerTip


Break and feed cylinder systems, sometimes referred to as feeder systems, feed alumina into reduction cells on a set schedule. The system consists of an air cylinder installed inside the alumina hopper, also known as an ore bin, which sits on top of the pot. When the feeder system is activated, crust breaker tips mounted on pneumatic cylinder rods extend downwards through the cryolite crust breaking a hole through the top layer of the bath. The system then pours a measured amount of alumina through the opening via an integrated hopper.
