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

Note 2: Maximum feeder disc revolutions in one screw recovery period (injection mode) is 9.5 revolutions. Use proper disc sizing for injection mode applications to ensure proper dispense of material during the recovery cycle. Maximum dispense during a recovery cycle should not exceed 9.5 revolutions of the metering disc.
