Australia's leading integrated fine paper-making and packaging papers complex, Maryvale Mill produces more than 500,000 tonnes of paper every year. The Maryvale Mill has three pulp mills, five paper-making machines, an ECF bleach plant, pulp lapping machine, finishing facility and a waste paper processing plant.
The Mill operates under stringent quality and environmental management standards (ISO 9001 and ISO 14001) and holds dual FSC and PEFC forestry Chain of Custody certifications.
The motors at the mill did not have any cover previously, and were exposed to pulp contamination on the motor frames and air intakes from the high spillage rates, resulting in regular winding failures, bearing failures as well as counter-productive high motor temperatures. The failure in motor components led to time-consuming and costly maintenance downtime.
The K-MotorShield motor covers were installed easily, with the whole process requiring only a single person to complete the job. The lightweight motor covers feature a simple snap-on design that allows quick installation.
The motor covers have been very effective in minimising the pulp getting into the end covers and clogging up the fins, eliminating the overheating problems. Significant cost savings are expected for the mill from reduced maintenance and repair of the motors.
The K-MotorShield motor covers have been installed on motors in some harsh environments at the mill, but no problems have cropped up to date.
