VIBRATORY FEEDERS AND CONVEYORS MODELS HVF, TM, HVC, SM, AND VMC The new Eriez Model HVF mechanical feeders are simple, 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—each one of which can be removed and replaced in less than two minutes if required—transmit the exciting force and can “fine tune” the motion of the trough to optimize the flow rate for a specific application. VB-3650R • Adjustable-angle rubber springs • Low profi le—minimum headroom • Flow rates to 60 ft/minute (18mpm) • Simple, stable, variable controller ONLY FROM ERIEZ FEATURES & BENEFITS

2 ©2007 ERIEZ MAGNETICS ALL RIGHTS RESERVED INTRODUCTION/ OVERVIEW AT LAST—THE SIMPLE, HIGHVOLUME VIBRATING FEEDER The remarkably compact, straight-line design of the Model HVF feeder presents an extremely low profile; minimum headroom is required for installation. The ability of the specially designed rubber springs to amplify the trough stroke results in low horsepower requirements. Power is provided by a standard three-phase, 230/460 volt TEFC 60 Hz motor. Explosion-proof motors are also available. Accurate control of flowrate is achieved by the standard control, i.e. hand-wheel adjustable,...

3 * Capacities are based on dry sand weighing 100 lb/cu ft (1600 kg/cu m) and coal weighing 50 lb/cu ft (800 kg/cu m) with the trough at a 10° downslope. Note: Horsepower subject to change depending on trough thickness, liners, etc. Trough lengths and widths other than those shown here are available. Capacities shown are for illustration only. Actual capacities vary due to installation factors such as downslope and hopper arrangement and/or material properties such as weight and moisture content. Consult Eriez for your specifi c application. Length Rated 36” 48” 60” 72” 84” 96” 108” 120” Model...

5 MODEL HVF – HIGH-VOLUME FEEDER Another Model HVS-18, this one with an 18” x 36” (457 mm x 914 mm) trough, is fi tted with a coarse wire screen. An overhead drive is utilized on this suspended Model HVS-36 with a 36” x 96” (914 mm x 2438 mm) trough. All part of the regular manufacturing mix at Eriez, these units offer the benefits of simplicity, reliabilitly and economy. The 14” diameter by 96” long (356 mm x 2438 mm) tubular trough on this unit that feeds dry cereals has see-through inspection ports at both ends so fl ow can be monitored. The grizzly on this 30” x 60” (762 mm x 1524 mm) trough...

10 HIGH-VOLUME MODEL HVC Additional length can easily be obtained with very little loss of headroom by having one conveyor feed into another. This 22 ft (6.7 m)-long HVC conveyor is typical of the rugged, yet simple, design. A standard three-phase motor is belt-connected to a variable-pitch sheave, factory set to drive an eccentric shaft at between 900 and 1,000 rpm, depending upon the length of the conveyor. The vibratory motion created by the shaft is amplifi ed and transmitted to the trough by polyisoprene springs, to which the trough is bolted. Heavy-duty construction throughout assures long...

SPECIFICATIONS 11 HIGH-VOLUME MODEL HVC HVC conveyors can be provided with V-shaped or completely enclosed troughs, as shown above and at right, as well as with screening decks and a variety of liners. Conveyors are usually base-mounted like the model at right but can also be suspended from overhead supports. In either case, vibration is isolated from the support structure by a special rubber assembly which forms part of the hanger or base-mounting arrangement.
