New Options for Mine-duty Screens

Deister Exciter Mechanism

Deister BFO1820 Screen with Isolation Base
Deister Machine Co. has introduced two new equipment options for mine-duty screens. The company’s Exciter Vibrating Mechanism is designed for use with large linear stroke screens and feeders. Multiple units can be positioned in series, and linked by flexible shaft couplings to provide better bearing life in conjunction with aggressive G-force. According to Deister, high-tech CNC manufacturing processes ensure tight tolerances and precision fits for the entire assembly, while innovative seal, shaft and bearing designs provide a rugged unit that is easy to maintain, especially when combined with the Deister System Saver Oil Filtration system. Removable external counterweight slugs allow for easy output force adjustment over a wide speed range. The Exciter Mechanism can be driven by V-belts or direct drive flexible shaft. Another option for large screens is the Deister Isolation Base, which incorporates a secondary set of support springs, as well as shock absorbers, further isolating the forces gen-erated by the vibrating screen frame from the stationary structure.
