The nickel handling system collects the powder from a kiln gas cyclone. The mild steel hopper is vee shaped and steep walled for best flow behaviour. The collecting screw features both left and right-hand flights for efficient central discharge. Nickel is a fine, highly dense powder making it highly abrasive. To mitigate the resulting wear, the flights of the screw have been treated with a hard wearing coating.“The original cyclone hopper design had a history of bridging which would cause production delays on the kiln. Projex were challenged to come up with a design concept to reduce the time delays. Ajax professionally turned the concept of this bridge breaking hopper into an engineered device on time and in budget to fit into a busy kiln refit programme,” said Ian Lund, Principal Engineer, Projex Solutions Limited.
