Model TMF-1248-660-4-(2)S with 12" x 48" trough and side mounted motors.
Low Profile Model TMF-1878-1320-4-(2) twin motor feeder with airmount isolation.
PRINCIPLES OF OPERATION TMF Twin Motor Feeders are designed to convey product by creating a linear straightline motion. Two counter-rotating B.E.S.T. INC. motors provide the linear (push-pull) action required. As the AC motors counter-rotate, the side forces cancel out and the linear forces are combined. With the motors properly attached and located on a rigidized trough suitable for the forces being exerted, and also suspended on isolation springs, the conveyance action is quiet and positive. No belts are required. The synchronized motors provide a semi-balanced design which eliminates the uncontrolled bouncing at shut down. Final motors 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 duty roller bearings are supplied on all 900 and 1200 RPM motors. 1800 RPM motors are factory grease packed and furnished with sealed ball bearings.
MODEL TMF TWIN MOTOR FEEDERS Adjusting the Feeder's Amplitude To vary the amplitude and resultant feed rate in the feeder pan, just remove both covers of each motor and set the force output to the desired percentage of maximum. All weights must be set to the identical percentage setting. (See diagram 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% of maximum force. IMPORTANT: Both ends of the motor must be adjusted to the same setting.
Variable Controller Model VS Variable Speed AC Inverter Type remote controllers are available for operation on 460/3/60 or 230/3/60 power input. Optional controller features include equipment control followers, overload functions, ramping adjustments and dynamic braking. Special input voltages also available.
INSTALLATION TMF Twin Motor Feeders can be arranged for either suspension or base installation. Here are helpful considerations for proper installation and maximum feeding efficiency.
Figure 1 Feeder trough length is determined by the material's static angle of repose and trough slope. The feeder trough must be of sufficient length to assure complete material shutoff when the feeder is at rest.
Figure 2 The dynamic angle of repose is the angle the material seeks while being vibrated and conveyed.
Figure 3 The projected length and width of the vertical opening should be two to three times greater than the largest particle dimension. Materials with bridging tendencies require sufficient openings to assure good product flow. Caution should be exercised in determining the vertical opening size to avoid excessive bin head-load on the trough. The projected horizontal opening is determined by the particle size and bed depth requirements to meet the design feed capacity. The minimum horizontal opening should be approximately two times the largest particle dimension, but not less than the bed depth required.

The twin counter-rotating motors offer a semi-balanced conveyor design ideal for long transfer applications. Lengths longer than 18' are typically handled by series mounting of units in tandem. For example, a 30' system is made up of two (2) 15' units in tandem. Dust tight trough units with tray covers and flexible connectors are also offered. Other options include stainless construction, sight ports and scalping screen decks. A variable speed controller is also avail-able for remote control. Power input to the vibratory motors is 230/460 volt, 3 phase, 60 cycle with other voltages and frequencies available on special order. Final feed rate capacity is subject to trough's final design configuration and bulk product being conveyed.
