Eriez HVF mechanical feeders are straight-forward, rugged, vibrating machines that move high volumes of bulk materials reliably and economically. The feeder is a two-mass vibrating system, spring coupled, excited by a motor-driven eccentric shaft. Adjustable-angle rubber springs transmit the exciting force which can “fine tune” the motion of the trough to optimize the feed rate for a specific application.
Adjustable-angle polyisoprene rubber springs
Low profile design requires minimum headroom
Suitable for high material load applications such as below hoppers
Feed rates to 60 ft/minute (18mpm)
Adjustable with variable frequency drive
Low horsepower requirements
Heavy-duty construction for rugged applications
Easily replaced standard motors
The remarkably compact, design of the Model HVF feeder presents an extremely low profile requiring minimum headroom for easier installation.
The ability of the specially designed polyisoprene rubber springs to amplify the trough stroke results in low horsepower requirements. Power is provided by a standard three-phase, 230/460 volt TEFC 60Hz motor. Hazardous environment motors are also available.
Adjustable, variable-speed sheaves or variable frequency controls are available to provide feed rate adjustability within acceptable operating frequencies.
