Section II. REPAIR OF CEMENT FEEDER
7-3.
Introduction. The cement feeder consists of a cylinder with radial fins that rotate in a close tolerance housing
located under the midpoint of the cement bin. Cement enters the top of the housing and is carried by the metering wheel
and dropped onto the aggregates as they are carried to the mixing trough by the main conveyor belt. A precise amount is
carried between the fins and recorded on the cement meter register through the cable pickup at the end of the shaft.
If moisture has gotten into the cement bin, the cement may have hardened and blocked the rotation of the metering wheel.
In such cases the cement feeder must be removed, disassembled and cleaned.
