The low profile, rugged machines have a compact design that allows for more room around equipment, smaller tunnels under stockpiles, and easier installation.
The straight-forward design of the HVF series incorporates a standard three-phase motor mounted within the base. It is connected by a belt to the factory-set, variable-pitch sheave, which drives the eccentric shaft at approximately 1100 revolutions per minute. The vibratory motion created by the shaft is amplified by the polyisoprene springs to which the tray is connected.
The HVF feeders utilise “off the shelf” variable frequency controls to adjust feeder output, and signal-following capability comes as standard.
The series includes nine models with capacities of up to 1820 tonnes per hour.
