Weigh feeder scales from Accuweigh were recently installed and commissioned by their Newcastle branch for Pacific Carbon’s plant at Kooragang Island.
Accuweigh is a major industrial weighing company in Australia and has extensive experience in all types of industrial weighing applications including weigh feeders, belt weighers and industrial weigh hoppers.
Two sets of weigh feeder scales were installed at the plant to identify the flow rate of coal being processed into the client’s high quality coke for use in steel manufacturing.
Each of the weigh feeders comprises of a weigh hopper mounted on four heavy duty industrial load cells that are connected to a digital weight indicator fitted with an analogue output card.
The analogue 4-20mA weight signals are fed into a PLC to calculate the flow rate of coal being discharged from the weigh feeders at a TPH (tons per hour) rate.
The PLC regulates the rate of coal discharged from the weigh feeder scales to achieve the required flow rate for optimum processing of the coal into high quality coke.
The weigh feeders are suspended from framework approximately 50 metres above ground level for direct feeding into the retort chambers where the conversion of coal into coke is initiated.
