9 AGGREGATES MANAGER March 2015 by Therese Dunphy, Editor-in-Chief tdunphy@randallreilly.com Your complete guide to new and updated equipment and supplies in the aggregates industry. Electromechanical vibrating feeder Deister Machine Co., Inc. will launch the newest addition to its lineup of screening, scalping, and feeding equipment — the New Deister Two- Mass Electromechanical Vibrating Feeder — at AGG1 in Baltimore. The feeder is designed to allow greater control over high-capacity feed rates and productivity, while lowering costs per ton in aggregate operations. Units in the Deister EMF Series incorporate a high-profile infeed lip and a heavy-duty formed deck with replaceable liners. A simplified drive is designed with an easy-access exciter frame, which houses the single vibrator motor. Deister says the design results in higher bearing life and eliminates the need to replace belts.
