Heavy-Duty Feeders
Syntron® Heavy-Duty Vibrating Feeders
Electromagnetic Feeder
Syntron® Vibrating Feeders for heavy industry are ideal for feeding a
wide variety of bulk materials from storage piles, hoppers, bins and silos.
Rugged and dependable, Syntron heavy-duty feeders are backed by years
of service-proven performance in the mining, aggregates, glass, cement,
chemical, wood products and steel industries.
Syntron Vibrating Feeders are designed to increase bulk handling
productivity with high, controlled feed rates to improve cost-per-ton
efficiency. Electromagnetic and electromechanical models are available.
With capacity ranges from 25 to 4,000 tons per hour, these feeders are
ideally suited for high-tonnage feeding. Feeder selection should include
consideration of production requirements, material characteristics, and
operating environment.
Syntron ® F-Series
Electromagnetic Feeder
Electromechanical Feeders
Syntron Vibrating Feeders are sub-resonant tuned, two-mass, springconnected systems. These features enable Syntron feeders to work
consistently under material damping and other varying headload conditions
with negligible changes in trough stroke. Sub-resonant tuning maintains
stroke consistency and speed stability, thus delivering higher capacities
at controlled feed rates.
Precise, sub-resonant tuning is a key characteristic of both types of
Syntron vibrating feeders. Electromagnetic models are tuned through
careful calculation of the number and thickness of the special leaf springs
required to accomplish the desired tuning ratio. Electromechanical models
are tuned by adjusting the operating speed to obtain the exact tuning
ratio. Because sub-resonant tuning is so critical to feeder performance, a
detailed explanation is provided for electromagnetic feeders on page 6
and for electromechanical feeders on page 17.
Dependable, flexible control sets Syntron vibrating feeders apart from
other feeding and conveying machinery. Material feed rates are controlled
and easily adjusted with Syntron solid-state controls; a wide range of
standard and special models is available. Control devices can also be
supplied for integration into systems that use external signals from
automatic sensing devices. In addition, control arrangements are available
for selecting and sequencing a group of feeders.

Syntron® electromagnetic feeders
Syntron® Heavy-Duty Electromagnetic Feeders
Bulk material feeding with full-range control.
Syntron® Heavy-Duty Electromagnetic Feeders come in ten
different models with capacities
ranging from 25 to 1600 tons per
hour.* These versatile feeders are
capable of handling a variety of
materials from the finest powders
to large, coarse particles.
Syntron Electromagnetic Feeders
can be supplied in various configurations including multiple- drive
units and above-deck drive units.
Above-deck drive units are recommended where there is insufficient
space below the trough.
Syntron Electromagnetic Feeders
require minimal maintenance as
there are no mechanical parts to wear
out, such as cams, eccentrics, belts
and bearings — thus eliminating
the need for lubrication. All movement is confined to the heavy-duty
leaf springs. Electrical components,
such as the coil, will provide years
of service under normal operating
conditions. Dust-tight drive units
are standard on all models.
Dependable, flexible controls provide
easily adjustable feed rates with
instantaneous response. A variety
of controls with special control
arrangements are available.
(For more information on
electromagnetic feeder controls,
see pages 14 and 15.)

Syntron® Electromagnetic
Feeders are normally installed
by suspension mounting with
four flexible wire rope cables.
They can also be supplied for
base mounting on a solid base,
or with a combination of base
mounting and suspension
mounting.
Syntron Electromagnetic Feeders are ideal for use in a stationary operation such
as a tunnel system from a surge pile. They are usually controlled from a remote
point to provide the desired feed rate. In this application,
a model FH-22 feeds limestone to a belt conveyor.

Syntron® electromagnetic feeders, cont’d.
Sub-Resonant Tuning for Electromagnetic Feeders
Low sub-resonant tuning is the
key characteristic of Syntron®
electromagnetic feeders, making
them the most stable and consistent
feeders available on the market.
Feeder tuning involves adjustment
of the natural frequency of the
feeder in relationship to its
operating frequency. If the operating
frequency is greater than the natural
frequency, the feeder is superresonant tuned, making it very
unstable under headload.
Conversely, if the natural frequency
is greater than the operating
frequency, the feeder is sub-resonant
tuned, making it more consistent
and stable under headload.
Electromagnetic feeders are tuned
through careful calculation of the
number and thickness of the special
leaf springs required to accomplish
the desired tuning ratio.
Regardless of manufacturer, all
heavy-duty, two-mass electromagnetic vibrating feeders are
sub-resonant tuned. For sub-resonant
tuned feeders, the distance from
resonance is critical to feeder performance. Most manufacturers tune
their feeders closer to resonance,
while Syntron electromagnetic
feeders are tuned further from
resonance.
6
The operating frequency of all Syntron® Heavy-Duty Electromagnetic Feeders
is checked at our test stations before shipment.
Material damping and other
variations in headload cause
fluctuations in capacity and feed
rates of all sub-resonant tuned
feeders. Because Syntron electromagnetic feeders are tuned further
from resonance, capacity and feed
rates remain more stable and
consistent even when the feeder is
subjected to material damping and
other variations in headload.
This is why Syntron electromagnetic
Feeders are the best solution for
rugged material handling
applications.

Electromagnetic Feeder Troughs
Syntron® Electromagnetic Feeder models FH-22 through F-88 can be furnished with standard flat-bottom troughs, special flat-bottom troughs or
belt-centering discharge troughs.
Drive units can be positioned either above or below the trough. A below-deck
drive unit is most commonly used, but above-deck drive units can be
supplied for installations where there is insufficient space below the trough.
However, an above-deck drive unit may reduce feeder capacity slightly.
Standard flat-bottom trough,
below-deck drive unit.
Capacities for feeder models with standard troughs are based on dry sand
weighing 100 pounds per cubic foot. Capacities vary depending on drive unit
location, material characteristics, material density, trough length and width,
trough liner type, feeder installation, skirt boards and hopper transitions.
Several trough options are available for special applications. Syntron® extralong feeder troughs can be supplied with either below-deck or above-deck
multiple electromagnetic drive units. Extra-long feeder troughs provide many
advantages in conveying materials over long distances; unlike belt conveyors,
there are no idlers or pulley drive units to wear, lubricate, or replace. Long
tubular troughs can convey pure, clean materials without atmospheric contamination and safely convey dusty, poisonous materials without endangering
processing personnel.

drive unit.
Other trough options include:
• Syntron vibrating inspection tables feed material forward at a smooth,
controlled rate of flow. This enables an operator to remove material
that does not meet specification.
Flat bottom trough, above-deck
drive unit.
• Syntron “spreader” feeders spread a wide, even layer of material with
a diagonal discharge trough or diagonal-slotted trough.
• Electrically heated trough liner plates minimize accumulation of damp or
wet materials in feeder troughs. Available only on specially designed feeders,
heated liner plates increase feeder efficiency by eliminating the downtime
required to clean troughs. They are especially effective for materials with
moisture contents ranging from five to fifteen percent. The electric heating
element is insulated and sandwiched between two steel plates.

Multiple-Drive Unit Electromagnetic Feeders
Syntron® Electromagnetic drive units can be
combined to create feeders ideally suited for special
applications.
Multiple-drive units, positioned one behind the other,
result in a long, vibrating conveyor. When an especially
wide material layer is desired, multiple-drive units can
be placed side by side on extra wide feeder troughs.
The number of drive units required is determined by
the trough width and length.
Dual-twin drive units — two sets of twin drive units,
one set placed behind the other — provide both
increased capacity and the ability to handle exceptionally
heavy loads.

Syntron® Heavy-Duty Electromagnetic Vibrating Feeder Controls
Solid-state DC signal controls accept a variable dc signal from an
external source and use it to vary the feed rate.
Standard Solid-State DC Signal Control
Solid-state load monitoring controls sense the electrical load on
process equipment motors to determine when the machine is
approaching an overload or underload condition and automatically
adjust feeder output to correct machine loading.
Solid-State Load Monitoring Controls
Remote controls permit manual adjustment of the feeder flow rate
from a remote station located at a distance from the feeder.
Remote Control
Constant-stroke controls automatically maintain the trough stroke
at any pre-set rate through the use of a trough-mounted inertial
stroke transducer (IST).
Constant-Stroke Control
Perfect for batch weighing or bagging operations. External
scale switches connected to the control automatically signal
primary fast material flow, secondary dribble flow and instant
shut-off at exactly the pre-selected weight.
Two-Rate Automatic Scale Control
Solid-state proportional controls permit individual material flow
settings on multiple feeders for a desired blend of materials. A
master control potentiometer permits simultaneous flow rate
regulation of all the feeders.

Sub-resonant Tuning for Electromechanical Feeders
Stroke consistency and speed stability for high-capacity feeding.
Low sub-resonant tuning is the key characteristic of Syntron® electromechanical
feeders, making them the most stable
and consistent feeders available on the
market.
Sub-Resonant Tuning for
Electromechanical Feeders
Feeder tuning involves adjustment of the
natural frequency of the feeder in
relationship to its operating frequency.
If the operating frequency is greater
than the natural frequency, the feeder is
super-resonant tuned, making it very
unstable under headload. Conversely, if
the natural frequency is greater than the
operating frequency, the feeder is subresonant tuned, making it more consistent
and stable under headload.
Regardless of manufacturer, all heavy-duty,
two-mass electromechanical vibrating
feeders are sub-resonant tuned. For subresonant tuned feeders, the distance from
resonance is critical to feeder performance.
Most manufacturers tune their feeders
closer to resonance, while Syntron feeders
are tuned further from resonance.
Material damping and other variations in
headload cause fluctuations in capacity
and feed rates of all sub-resonant tuned
feeders. Because Syntron electromechanical feeders are tuned further from resonance, capacity and feed rates remain
more stable and consistent even when the
feeder is subjected to material damping
and other variations in headload. In
addition, Syntron electromechanical
feeder design incorporates internal
damping, which contributes to their
stability and consistency.
On the comparison chart (Figure 1),
curve 1 represents a typical competitive
feeder in a no-load state without internal
damping. Curve 2 represents a Syntron
feeder in a no-load state with internal
damping. Curve 3 represents a feeder
with material headload and associated
Figure 1. Comparison of Tuning Ratios
damping. Because Syntron feeders are
tuned further from resonance and are
designed with internal damping, it is
evident that the loss in relative trough
stroke under headload for a Syntron
feeder (Y) is negligible as compared to a
substantial loss in relative trough stroke
for competitive feeders (X). This is why
Syntron electromechanical feeders are
more consistent and stable than any
other feeder, even when subjected to
material damping and other variations
in headload.

Syntron® RF electromechanical feeders
RF Medium-Duty Electromechanical Feeders
These master material movers can feed it all.
Syntron® RF Medium-Duty Electromechanical
Vibrating Feeders meet the varying, mid-range
bulk material handling needs of industry.
Capable of handling a wide range of materials,
these two models provide feed rate capacities
from 100 to 600 tons per hour.*
Syntron RF feeders are two-mass vibrating
units; the trough is one mass and the exciter
unit is the other. The exciter is belt-driven by a
standard-frame induction motor and connected
to the trough with long-life polymeric shear
springs. The ball bearings in the exciter unit
have a minimum life expectancy of 20,000 L10
hours.
Variable pitch motor sheaves provide a positive
method of tuning. This Syntron design permits
higher feed capacities from smaller trough
sizes, enabling you to select a more economical
unit to meet your capacity requirements.

Variable operating speeds and trough stroke,
combined with the damping characteristics of
polymeric shear springs, are significant factors
in the performance capabilities of Syntron RF
Medium-Duty Electromechanical Feeders.
All Syntron RF Feeder motors are labeled for
inverter duty and vibration service and are
furnished with a cast-iron frame. Special motors
can be supplied to meet UL explosion-proof
requirements.

MF Heavy-Duty Electromechanical Feeders
The high-capacity performers.
Syntron® MF Heavy-Duty Electromechanical Feeders
are the heavy-weights of bulk material handling and
are used for higher capacity requirements. The eight
heavy-duty models handle capacities from 100 to 4,000
tons per hour.*
Syntron Heavy-Duty Electromechanical Feeders combine
extra structural strength with durable com-ponents.
The deep wing plates form a bridge between inlet and
discharge suspension supports, providing extra strength
for years of dependable service. Standard troughs
feature unitized weldments — one-piece, completely
welded units for greater strength. Troughs are also
available with bolt-together construction for tunnel
installations or other confined areas.
Syntron® MF-200 Electromechanical Feeder feeding
slag at 250 TPH to a crusher.
MF Heavy-Duty Electromechanical Feeders are twomass, spring-connected and sub-resonant-tuned. The
exciter unit is connected to the trough with corrosion
resistant polymeric springs, which are more stable
under varying conditions. The springs are compressed
for improved load stability, improved feed angles and
straight line motion. The spring design eliminates
pinch points, an important safety feature. Exciters in
these heavy-duty feeders use double roll, spherical roller
bearings, with L10 expectancies up to 140,000 hours.
All Syntron MF Electromechanical Feeder motors are
labeled for inverter duty and vibration service, and are
furnished with a cast-iron frame. Special motors can
be supplied to meet UL explosion-proof requirements.
Attachments for safety cables are included on all

Recommended Designs for Hoppers and Transitions
Feeder Transition Hoppers
Feeder capacity depends on the design of the hopper. Material characteristics such as size distribution, shear properties and cohesiveness generally
dictate the configuration of feeder transition hoppers. Material flow
velocities vary, depending upon material properties, feeder stroke and
operating speed.
Good transition hopper design optimizes flow rate, resulting in the most
economical choice of a feeder. Improperly designed transition hoppers
will substantially reduce feeder capacities.
Figure 1 illustrates Ideal and Acceptable Hopper designs.The Ideal Hopper
with a throat (T) to gate height (H) ratio of 0.6 shows a uniform material
flow pattern to the feeder trough. Material at the front and rear of the
hopper moves at nearly the same velocity, and the discharge depth (d) is
nearly equal to the hopper gate height. The Ideal Hopper design allows
the most economical feeder to be used.
The Acceptable Hopper design may require a slightly larger feeder than
required for the Ideal Hopper design. This is due to the non-uniform
flow pattern of material at the rear of the hopper. Material flow velocity
is reduced, material depth “d” is reduced and there is a reduction in feeder
capacity. A T/H ratio of 0.6 to 1.0 is generally acceptable. However, when
the T/H ratio exceeds this range, the material flow patterns distort
drastically and will significantly reduce capacities.

Suggested Electromagnetic Size
If material size is -4-in with a trough down slope of 10 , use 35 ft/min.
If material size is +4-in to -12-in with a trough down slope of 10 , use 30 ft/min.
If material size is +12-in with a trough down slope of 10 , use 25 ft/min.
˚
˚
˚
Suggested Electromechanical Size
If material size is -4-in with a trough down slope of 10 , use 55 ft/min.
˚
If material size is +4-in to -12-in with a trough down slope of 10 , use 50 ft/min.
˚
If material size is +12-in with a trough down slope of 10 , use 45 ft/min.
˚
Feeder down slope usually effects flow rate by 2% per degree. As down slope
increases flow rate increases. As down slope decreases flow rate decreases.

and sides

Recommended Hopper Design and Feeder Selection
Refer to Figure 2.
1. Rear wall angle steep enough to permit material flow (60˚ ± 5˚).
2. Front wall angle just enough to permit material flow (55˚ ±5˚).
3. The throat dimension “T” for random size material should be a
minimum of 2 times the largest particle of material. For particles
that are nearly the same size (near size), “T” should be a minimum
of 4 times the largest particle size to prevent blockage at the
throat opening. In all cases, the arc “A” should exceed 2 1/2 times
the largest particle size.
4. Gate opening “H” must be a minimum of 2 times the largest
particle of material and should increase proportionally for the
desired capacity. The most economical feeder is selected when
the throat dimension “T” is equal to or slightly larger than H/2. If
“T” is greater than “H” the flow pattern of the material is disturbed,
resulting in non-uniform flow.
5. When adjustable gates are used, the gate must be parallel to the
hopper’s front wall and must be as close to the front wall as possible.
The separation must not exceed 2 inches. The gate should act as
an adjustable front wall. Leveling blades and down stream gates
must not be used. Horizontal cut off gates should be used to
perform feeder maintenance and must not be used to regulate flow.
6. The inside width of the opening “D” (between stationary skirt
boards) should allow for a 1-inch clearance between the feeder
trough and skirt boards and should be a minimum of 2 1/2 times
the largest particle size. For near size material the width of “D”
should be a minimum of 4 times the largest particle size.
Figure 2. Ideal Hopper Illustration
7. The minimum length of the feeder is determined by projecting
the angle of repose for the specific material from the gate point to
the feeder pan and adding approximately 6 inches.
8. The feeder must not contact any adjacent structure but must be
free to vibrate. Allowance must be made for a decrease in feeder
elevation of approximately 2 inches, due to static material load. In
addition, 1 inch minimum clearance at sides and 1 1/2 inches at
bottom and back must be maintained in both loaded and
unloaded conditions.
9. The skirts must taper in the direction of flow (diverge from
conveying surface) to prevent material from jamming and causing
additional problems such as spillage and build-up. Skirts must run
parallel to trough sides and must be reinforced to resist bulging
outward against trough.
