Acrison's Volumetric Feeders
Choose from industry's widest selection of proven, high performance dry
solids volumetric feeders for the one best suited for your application
Volumetric Metering
Throughout the various processing industries, the requirement to meter dry
bulk solids is not only commonplace, but also, usually one of the more critical
elements associated with a given manufacturing process. In fact, the overall
performance of the feeding equipment, more often than not, is directly
proportional to the quality of the end product. Very simply, a volumetric feeder
is a device that meters by volume, as opposed to a gravimetric feeder,
which meters by weight.
Because of their lower cost and simplicity, volumetric feeders are more
widely utilized. A true volumetric feeder encompasses a method of measuring
volume and a means to discharge that measured volume over a variable range by
varying the speed of the feeding mechanism. Acrison manufactures a number of
different model auger type dry solid volumetric feeders, each possessing their
own individual principle of operation, since no single approach to volumetric
feeding has been able to solve all material handling variables.
Acrison's dissimilar speed multiple auger type metering mechanisms are
universally acknowledged as the most viable and reliable. This document
describes the most popular Acrison Volumetric Feeder models.

and 140-2.
Unlike volumetric feeders where a single auger is located at the very bottom
of a converging "V" shaped trough - across which amorphous products
easily and often bridge - Acrison's various model dissimilar speed, Double
Concentric Auger Dry Solids Volumetric Feeders not only assure both positive
flow and feed, but also, always maintain total control of the product for
unsurpassed levels of performance
 Especially
effective when metering the many different varieties of amorphous products, the
unique "Inter-Auger-Action" produced by the rotation
of the Double Concentric Augers operating at dissimilar speeds
"conditions" the product to a remarkably uniform density while
circumferentially filing the metering auger precisely, efficiently and reliably.
The standard output capacity for the Model 105 Series of Feeders ranges
between 0.002 and 202 cubic feet per hour.
The standard output capacity for the Model 140 Series of Feeders ranges between

MODEL 170 FEEDER SERIES
 Designed
with a circular, flat bottom feed chamber with a non-restrictive, non-converging
product inlet, a slow-speed horizontally rotating "conditioning"
agitator ensures positive flow of product from within the feeder's integral
supply hopper into the feed chamber and into the metering auger located beneath.
Dead zones do not exist and consequently, product stagnation cannot occur
anywhere within the feeder.
With only a few moving parts, Model 170 Series Metering Mechanisms have the
unique ability to "self-empty" - when permitted to feed until empty,
or to "empty-quickly" - when the need to empty the feeder rapidly
exists. The latter is accomplished by means of a novel discharge port located in
the flat bottom of the feed chamber. Clean-out is extremely fast, simple and
complete. The standard output capacity for the Model 170 Series of Feeders
ranges between 0.003 and 140 cubic feet per hour.

unique and versatile combination of Acrison's multiple auger/agitator bin
discharging mechanism with a metering auger (operating at dissimilar speeds),
specifically designed to ensure both positive product flow and feed. These
extremely versatile, triple auger/agitator volumetric feeders are capable of
metering even the most difficult-handling dry solids ingredients.
The standard output capacity for the Model BDFM ranges between 0.0006 and 3
cubic feet per hour.
The standard output capacity for the Model BDF-1 ranges between 0.0015 and
6.5 cubic feet per hour.

Model 407 Series Weigh Feeders
 For
Continuous or Batch Weigh Feeding Applications Highest Performance, Quality and
Value.
The Model 407 is a low profile, economically priced Weigh Feeder employing
Acrison's advanced “Weight-Loss-Differential” weigh feeding concepts and
designs for accurately and reliably metering a wide variety of dry solid (and
liquid) ingredients at feed rates ranging from approximately one pound to
several thousand pounds per hour.
Encompassing strong, field-proven weighing technology, specifically developed
by Acrison for “Weight-Loss” weigh feeding applications, the Model 407
utilizes a uniquely configured, open “platform” type lever weighing system
where the selected metering device "mounts" onto a weigh platform.
This robustly constructed lever weighing network is in itself a “scale”
utilizing frictionless stainless steel flexures for all pivotal connections. As
weight is added to or removed from the weigh platform, the lever network
“moves” in a direct relationship to that weight. This movement is precisely
sensed by Acrison's Ratiometric Digital Weight Resolver and instantaneously
converted into a highly accurate digital signal directly proportional to weight.
Unlike “weight-loss” weigh feeders that incorporate weighing systems
designed with one or more load cells…well known for their temperamental
behavior and calibration drift…Acrison weighing systems do not use load cells
or any other type force measurement device for sensing weight.
Designed for unsurpassed precision, reliability and longevity, the
Ratiometric Digital Weight Sensing System produces unamplified resolution of
over one part in one million. Also, because the actual sensing element of the
Ratiometric System does not physically attach to any part of the lever weighing
network, it cannot be damaged by any magnitude of shock or overload that the
weighing system may experience. The Ratiometric Digital Weight Sensing System is
entirely adjustment-free.
Analogous to the weighing mechanisms used with all of Acrison's various model
“Weight-Loss-Differential” Weigh Feeders, the Model 407 Weighing System is
also permanently calibrated and will remain precise without the need for
recalibration and/or adjustment. In addition, this weighing mechanism is not in
any way delicate and/or temperamental and will operate over an ambient
temperature range of –10 to 140 degrees Fahrenheit. Optionally, it can be
furnished in all stainless steel construction.
Continuous metering accuracy typically ranges between +/- 0.25 to 1
percent or better (error) at two sigma, based on a given number of consecutive
one minute weighments.
The Model 407 Weigh Feeder is available with five different Acrison dry
solids metering mechanisms… the Models 101-0, BDFM, 170-00, 170-0 and 105.

Refill Mechanism
Refilling a supply tank is also usually completely automatic, typically
performed by either an automatically operated valve, or by means of a transfer
pump.
Metering Pump
Selection of the metering pump will vary depending upon product
characteristics and feed rate requirements. The pump will be of the highest
quality, specifically selected to handle the specified liquid. When desired, and
if feasible, Acrison can adapt an existing pump to a

metering mechanism, hopper size, scale capacity, product bulk density and
frequency of refills.
Models A405 and 406 Series of Weigh Feeders
The Models A405 and 406 are small and compact precision weigh feeders
utilizing Acrison's highly advanced and widely recognized
"Weight-Loss-Differential" concepts and technology to provide
unexcelled "total performance" in metering a wide variety of dry solid
or liquid ingredients... virtually maintenance-free devices that do not require
rezeroing, calibration or adjustment.
Each model weigh feeder is available with several different type metering
mechanisms... the selection of which is determined by the physical handling
characteristics of the product or products to be metered and/or the feed rate
requirements.
For the Model A405, feed rate capability ranges from approximately two pounds
upwards to several thousand pounds per hour... also predicated on the selected
metering mechanism, hopper size, scale capacity, product bulk density and
frequency of refills.
The Model 406 Weigh Feeder has a minimum feed rate capability of about 0.10
pounds upwards to approximately 800 pounds per hour... likewise predicated on
the selected metering mechanism, hopper size, scale capacity, product bulk
density and frequency of refills.
Today's very demanding processes require Weigh Feeders that are highly
accurate and very reliable; they cannot be temperamental, delicate and/or
maintenance-intensive.
Their mechanical designs and materials-handling capabilities must be proven
viable and versatile. Their control systems must be leading-edge in design,
functionality and interfacing capabilities.
Acrison Weigh Feeders are the most advanced, precise and durable in the
industry. They are also the most flexible, boasting an unprecedented number of
superior features. Their time-proven, uncommonly rugged weighing systems are the
envy of the industry. And, Acrison Weigh Feeders require exceptionally low
maintenance.
Model 400(B) Series of Batch Weigh Feeders
 When
operating in a "Batching Mode," any of Acrison's various Model 400
Series of Weigh Feeders provide optimum accuracy and versatility.
Designed for small to medium size ingredient batching (dry solids or
liquids), Acrison's various Model 400 Series
"Weight-Loss-Differential" Weigh Feeders are available in two basic
batch weighing operational arrangements to suit the exacting requirements of a
given application. [When configured to operate as a batch weigh feeder, the
feeder model designation is followed by a (B)].
- Batch Volumetric Feed...
- metering product continuously and volumetrically to the desired batch
(weight) amount over a period of time.
- Batch/Gravimetric Feed...
- metering product continuously and gravimetrically to the desired batch
(weight) amount over a period of time.
In utilizing the "weight-loss" concept for batch weighing, the
exact amount of the selected batch size (or batch weight) is discharged from the
feeder; then, the feeder stops.
Most significantly, the common problem of variable product accumulation
anywhere on the weighing system (internally and/or externally) affecting
accuracy, typically associated with batch/dump type weighing systems, cannot
occur with a "weight-loss" type Model 400(B) Batch Weigh Feeder. And
assuming the weighing system of the "weight-loss" feeder is accurate
and reliable, batch-weighing performance will be very precise and dependable.
Unlike load cell based weighing systems, which require periodic re-zeroing
and re-calibration, and which are also delicate and temperature sensitive,
Acrison's permanently calibrated, high resolution, rugged-duty, non-load cell
weighing systems offer users a high comfort level. They are also adjustment and
calibration-free, require near-zero maintenance, and boast exceptionally long
life.
Acrison batch weighing systems may be controlled by one of Acrison's
multiprocessor controllers, the selection of which is determined by user
preference and/or the specifics of a given application.
Regardless of the characteristics of the dry solid ingredient(s), Acrison's
wealth of expertise in this very specialized industry provides a viable solution
to your batch weighing requirements.
Batch accuracy typically ranges between ± 0.1 to 0.5 percent or better
(error) at two sigma, based on a given number of consecutive weighments.
Model 403B(D) Series of Batch/Dump Weighing Systems
Acrison's Model 403B(D) "Batch/Dump" Weighing Systems also
utilize Acrison's non-load cell, counterbalanced, high resolution weighing
mechanism.
- Batch/Dump (single ingredient)...
- meter product into the appropriate size Model 403B(D) Weigh Hopper (or
Tank) to a preset weight and then, discharge the entire contents upon
command.
- Batch/Dump (multi-ingredient)...
- meter product (sequentially) into the appropriate size Model 403B(D)
Weigh Hopper (or Tank) to individually preset weights and then,
discharge the entire contents upon command.
With the various batch/dump arrangements, the total weight or amount of
product in a given batch must be encompassed within the weigh hopper (or tank).
Therefore, the weigh hopper (or weigh tank for liquids) must be designed
sufficient in size to hold the entire amount of the largest desired total batch.
Upon the initiation of each batch, the controller automatically rezeroes the
scale to ensure optimum performance.
Acrison's various Model 403B(D) Batch Weighing Systems may be controlled by
one of Acrison's multiprocessor controllers, the selection of which is
predicated on user preference and/or the specifics of a given application.
Batch accuracy typically ranges between ± 0.1 to 0.5 percent or better
(error) at two sigma, based on a given number of consecutive weighments.
Model 404BZ(BU) Bulk Bag Unloader Batch Weigher
 For
precision batch weighing out of bulk bags.
The Model 404BZ(BU) is a precision batch weighing system consisting of an
Acrison rugged-duty, ultra-high resolution, non-load cell, counterbalanced
"platform" type weighing mechanism upon which an Acrison Dry Solids
Feeder and a Metalfab Bulk Bag Unloader are mounted... uniquely configured and
designed to precisely weigh the discharge of product, on a batch basis, by a
highly advanced multiprocessor control system.
In operation, product discharges out of the bulk bag unloader and into the
feeder beneath. Upon command, and in precise relation to a batch-weight
selection, the feeder meters product until the desired batch weight has been
reached, and then stops. The Model 404BZ(BU) Bulk Bag Unloader Batch Weigher is
not designed for continuous operation; it has been specifically designed for
batch weighing.
Acrison Model 404BZ(BU) Batch Weighing Systems may be controlled by one of
several Acrison multiprocessor controllers, the selection of which is determined
by user preference and/or the specifics of a given application.
Batch accuracy typically ranges between ± 0.2 to 0.5 percent or better
(error) at two sigma, based on a given number of consecutive weighments.
Acrison's Weigh Belt & Weigh Auger Weigh Feeders
Model 260 Series Weigh Belt Weighers/Feeders
 A
multiprocessor controlled, rugged-duty, fully digital weigh belt weigher
(wild-flow) and weigh belt weigh feeder series to satisfy high capacity weighing
requirements. Model 260 Feeders/Weighers also feature an Acrison high
resolution, non-load cell based, counterbalanced weighing system mounted
above the weigh belt, out of the product metering zone.
Standard feed output capacities range from approximately 80 to 7100 cubic
feet per hour (higher and/or lower capacities may be available).
Weighing or metering accuracy typically ranges between ±0.25 to 1 percent or
better (error) at two sigma, based on a given number of consecutive one minute
weighments.
Model 270 Series "In-Line" Weigh Feeders
 Representing
a revolutionary new concept for continuous weigh feeding, the Model 270 Series
offers processors an economical, precise and reliable method for metering a wide
variety of dry solid ingredients at moderate to high rates in an
"in-line" vertical configuration.
Developed in direct response to user needs, the Model 270 Series of Weigh
Feeders provide accurate and dependable performance in a totally dust-tight,
vertical in-line configuration. With their compact design and only one moving
part, these novel weigh feeders typically require less installed space than most
other type heavy-duty weigh feeders having similar throughput capacities.
In operation, a circular weigh chamber, housing a series of rotating
"weigh pockets", is mounted onto an ultra high resolution Acrison
weighing system. A separate variable output metering device (or prefeeder),
typically a rotary valve or screw type metering mechanism, attached directly to
product supply, feeds material into the top inlet of the weigh feeder within
which the slowly rotating constant speed "weigh pockets" continuously
weigh the product. Material is then discharged through the bottom outlet of the
weigh feeder, which is directly (or vertically) in-line with its inlet.
As material is fed into the weigh chamber, a weight signal is produced that
is instantaneously calculated into a continuous feed rate by the weigh feeder's
controller. Based on this calculation, the controller modulates the speed of the
prefeeder so that its output precisely matches the selected feed rate, resulting
in an accurate, continuous and uniform flow of material.
Model 270 Series Weigh Feeders utilize Acrison's exclusive counterbalanced
weighing system, equipped with Acrison's Ratiometric Digital Weight Resolver for
superior weight sensing and trouble-free long-term operation. Thus, because of
the counterbalanced design of the weighing system, only the net weight of the
material within the feeder's weigh chamber is actually weighed. In turn, optimum
weight sensing resolution is realized, producing the highest possible degree of
metering accuracy.
Acrison's Model 350 Continuous Blenders
"THE BLENDER WITHIN A BLENDER"... Featuring two concentrically
mounted augers rotating at dissimilar speeds for the thorough and
homogeneous blending of two or more dry solid ingredients
In operation, the Model 350 Blender provides...
- a unique annular interaction generated by the speed differential of the
concentrically mounted, dual blending augers.
- dissimilar longitudinal velocities produced by the speed differential
between the dual blending augers.
- an alternating forward and reverse action produced by the right and left
hand helix configuration of the larger (outer) blending auger.
- a "tumbling" action created by a number of horizontal bars
strategically located and affixed to sections of both augers.
"INTER-AUGER" BLENDING ACTION
The Model 350 is a versatile, multi-purpose continuous blender utilizing
Acrison's unique, dissimilar speed, Double Concentric
Auger Mechanism for the homogeneous and highly efficient mixing of dry solids
with dry solids, and depening upon the specifics of certain applications, dry
solids with liquids.
The action imparted to the material within the Model 350 Blender by the dissimilar
parallel motion of the dual concentric augers operating at different speeds,
produces a gentle, but extremely thorough blend of the ingredients being
continuously metered into it. Retention time within the blender is minimal and
the output delivery of the blended product is smooth and consistent.
Because of the many possible variations that can occur when mixing dry solids
to dry solids, or liquids to dry solids, Acrison recommends that a physical
evaluation of blending efficiency be performed in our Customer Demonstration
Facilities with the actual materials to determine feasibility of the application
and performance of the Model 350 Blender.
Model 350 Double Concentric Auger Continuous Blender
The effectiveness of Acrison's Model 350 multipurpose Blender has been proven
time and time again in both common and uncommon applications. Even products
having input feed ratios as much as 2000:1 are successfully blended. Versatility
is broad... ranging from the simplest and basic coating of a pelletized product
with a lubricant or a releasing agent, to the mixing of a paste-like blend
having the consistency of dough.
Operating at a constant speed, the Model 350 Blender is designed to function
in a "starved" condition. Product retention is fixed but initially
variable in order to produce optimum blending efficiency as necessitated by the
requirements of the specific application. Although the major portion of the
blender is "fixed" dimensionally, some flexibility does exist with
respect to the length of its discharge cylinder.
The quick disconnect and/or sanitary features available with the Model 350
Blender are designed for the rapid remove/ and cleaning of all major components
without the need for tools. The Sanitary Model 350 Blender is USDA approved and

"A SINGLE HELICOIDAL AUGER BLENDER"... Featuring a specially
designed helical blending auger for the thorough blending of two or more dry
solid ingredients
Model 301 Continuous Blender
 The
Model 301 is an inexpensive, moderately versatile, single auger Continuous
Blender designed for the thorough mixing of two or more dry solid ingredients.
This particular model blender basically consists of a single helical blending
auger housed in a trough or tube. Although standard Model 301 Blenders maintain
specific dimensional parameters, the length of this blender may be designed to
satisfy the layout requirements of a particular application in conjunction with
Acrison feeders.
Helicoidal Blending Auger
To provide optimum blending efficiency, a specially designed helical blending
auger is furnished with Acrison's Model 301 Blender. In operation, the rotating
blending auger tumbles the material while at the same time, produces a partial
bidirectional flow pattern that together, effectively and efficiently mixes the
dry solid ingredients (being continuously metered into it) into a uniform blend.
The design of the Model 301 Blender design permits control over the retention of
solids and subsequently, the degree of mixing.
The quick disconnect and/or sanitary features available with Acrison
equipment provide for the rapid disassembly and cleaning of all major components
without the need for tools. Sanitary equipment as manufactured by Acrison
strictly complies with federal sanitary codes.

Equipment demonstration in progress
 |
Acrison strongly encourages a prospective user of dry solids metering
equipment to visually and physically compare the available devices in order to
select the most viable hardware to satisfy process metering requirements.
Clearly there is a difference... a significant difference in technology, the
design, quality, durability, maintenance parameters and attainable performance
of the available dry solids metering equipment. For example, certain
applications require a high degree of short term accuracy and smoothness of
feed. To achieve this type of performance, Acrison has developed a variety of
unique and novel mechanisms which can accomplish this task effectively and
accurately. These mechanisms are capable of producing typical metering
accuracy's of ± 1 to 3 percent or better (total deviation) based on a given
number of consecutive short-term weighments, on intervals as brief as 0.1
seconds in duration.
Acrison's new, ultra-modern equipment demonstration facilities are the
largest, most advanced and best equipped in the industry. These capabilities
include the ability to test at actual production feed rates. Acrison is always
available to demonstrate the operation of the selected piece of equipment with
the users actual product, normally without any charge for such testing. Test
procedures are generally completely automatic.
In addition to equipment demonstration/ materials testing, Acrison also
offers comprehensive user training programs, focusing on equipment
operation/maintenance, as well as customized seminars dealing with the
application of Acrison products.
