Eriez Offers Feeders With Up to 2,000 TPH Capacity

PTP HVFFeeder 150

PTP HVFFeeder 400FEriez HVF Mechanical Feeders are available in nine models and can control up to 2,000 tph (1,820 mt) of material. These low-profile machines move high volumes of bulk material reliably and economically, according to the company. Their compact design allows for more room around equipment, smaller tunnels under stockpiles and easier installation.

A variety of trough sizes and types are available to meet practically any heavy-duty application requirements. Trough widths range from 18 in. (457 mm) up to 84 in. (2,135 mm) and lengths from 36 in. (914 mm) up to 120 in. (3,048 mm).

The Eriez HVF Mechanical Feeder is a spring coupled two-mass vibrating system with motor-driven eccentric shaft. The hand-wheel adjustable variable-speed sheaves help to achieve an accurate control of flow rate, which can be up to 60 ft. per minute.

Feeders are usually suspended with a downslope of up to 10 degrees. At this downslope, the HVF Mechanical Feeders can attain velocities up to 100 ft. (30 m) per minute.

A standard three-phase motor mounted behind the base frame of the HVF Feeder is belt-connected to the factory set variable-pitch sheave, which drives the eccentric shaft at approximately 1,100 rpm. The vibratory motion created by the shaft is amplified by the polyisoprene springs to which the tray is connected.
