    Vibratory Feeder supplied to an OEM manufacturer of

    scrap processing equipment, used in an auto- mobilematerials reclaiming operation. Trough is lined with 5/8"thick UHMW Polyurethane.

    MODEL TMF-3072 twin motor feeder with overhead coil spring suspension mounting. Trough is 30" wide 72" long with replaceable abrasive resistant liners.

    Model TMF-1248-660-4-(2)S with12" x 48" trough and side mountedmotors.

    Low Profile Model TMF-1878-1320-4-(2) twin motor feederwith airmount isolation.

    PRINCIPLES OF OPERATIONTMF Twin Motor Feeders are designed to convey product by creating a linear straightlinemotion. Two counter-rotating B.E.S.T. INC. motors provide the linear (push-pull) actionrequired. As the AC motors counter-rotate, the side forces cancel out and the linear forcesare combined. With the motors properly attached and located on a rigidized trough suitablefor the forces being exerted, and also suspended on isolation springs, the conveyanceaction is quiet and positive. No belts are required. The synchronized motors provide a

    semi-balanced design which eliminates the uncontrolled bouncing at shut down. Finalmotors selected can be either 1800, 1200 or 900 RPM, depending upon amplitude required.Final motor horsepower selected is a function of trough weight and TPH capacity required.All motors are continuous duty rated at maximum force. Grease fittings and heavy dutyroller bearings are supplied on all 900 and 1200 RPM motors. 1800 RPM motors are factorygrease packed and furnished with sealed ball bearings.

    MODEL TMF TWIN MOTOR FEEDERS

    Adjusting the Feeder'sAmplitudeTo vary the amplitude andresultant feed rate in thefeeder pan, just removeboth covers of each motorand set the force output tothe desired percentage ofmaximum. All weights mustbe set to the identicalpercentage setting. (Seediagram at right.)

    ENLARGED VIEW OF % FORCE DECAL

    All B.E.S.T. motor vibrators are easily adjusted by setting the dot on

    the eccentric weight to the proper (% of maximum force) output.The photo at left shows the operator setting the weights at 50% ofmaximum force.IMPORTANT: Both ends of the motor must be adjusted to thesame setting.

    Variable ControllerModel VS Variable Speed AC Inverter Type remote controllers are available for operationon 460/3/60 or 230/3/60 power input. Optional controller features include equipmentcontrol followers, overload functions, ramping adjustments and dynamic braking. Specialinput voltages also available.

    INSTALLATIONTMF Twin Motor Feeders can be arranged for either suspension or base installation. Hereare helpful considerations for proper installation and maximum feeding efficiency.

    Figure 1Feeder trough length is determined by the material's static angle of repose and trough slope. The feedertrough must be of sufficient length to assure complete material shutoff when the feeder is at rest.

    Figure 2The dynamic angle of repose is the angle the material seeks while being vibrated and conveyed.

    Figure 3The projected length and width of the vertical opening should be two to three times greater than the largestparticle dimension. Materials with bridging tendencies require sufficient openings to assure good productflow. Caution should be exercised in determining the vertical opening size to avoid excessive bin head-loadon the trough. The projected horizontal opening is determined by the particle size and bed depthrequirements to meet
