Note 1: This guide is to be used for general disc selection for Digital Dosing unit applications. All rates shown are based on continuous throughput of free-flowing materials. Consult factory for regrind, powder and all hard-to-flow materials.

Note 2: Minimum recovery time is one (1) second, and maximum rate is 9.5 disc revolutions in one screw recovery cycle (injection

mode). Use correct disc for molding applications to ensure proper dispensing of material during the recovery cycle.

Note 3: Feeder should not run continuously below 15% of maximum speed – use lower RPM motor or disc with smaller pockets.

Note 4: 35.5. and 38 rpm motors can only be used with soft pellets – may not have enough torque to cut hard pellets, i.e. PC, PET, nylon, etc., especially when the shear gets dull.
