The APPMD cast iron screw feeders are a solution that allows the use of a wide range of fuels in loose and granular form, from 0 to 32mm. The main fuel is coal in the 0-32mm granulation (from fines to pea-sized). The feeder construction uses grey cast iron, which helps reduce the noise level during operation and shows a lower tendency to transmit vibrations to other components of the boiler.
