Introduction
This user’s guide describes the RAM5 ResonantAcoustic® mixer and explains its operation.
This chapter provides an overview of the RAM5 and contains general information important to
correct use.
ResonantAcoustic® Mixing (RAM) Overview
The RAM technology approach for acoustic mixing works on the principle of creating micro-
mixing zones throughout the entire mixing vessel as well as macro (bulk) material flow fields.
This approach differs from conventional mixing technology where mixing is localized at the tips
of the impeller blades, at discrete locations along the baffles, or by co-mingling products
induced by tumbling materials. This new technology provides faster, more uniform mixing
throughout a vessel than can be created by conventional, state-of-the-art mixing systems. RAM
technology has an added advantage that it does not use impellers or other intrusive devices to
mix, and does not require unique vessel designs for a broad range of mixing applications.
RAM technology is compatible with many types of materials, which include liquid-liquid, liquid-
solid, gas-liquid, and solid-solid systems. The technology can be utilized to mix low viscosity,
highly viscous and non-Newtonian systems, as well as solid-solid systems in the same types of
vessels, without changes to impeller design, baffles, or other complicated, intrusive
components, such as injectors and nozzles.
RAM technology is designed to operate at mechanical resonance. At this operating condition
the RAM technology results in a near lossless transfer of the mixer systems’ mechanical energy
into the materials being mixed. This is created by the propagation of a pressure wave in the
mixing vessel. This condition is achieved by matching the mechanical operation of the mixer
with the properties and characteristics of the range of materials to be mixed. The operating
characteristics of the mixer are automatically sensed and controlled to keep the system at the
mixing acceleration established to provide the best mixing performance.
Achievement of these mixing conditions requires a methodology that is patented and unique to
RAM and RAM control technology; unachievable by any other mixing technology in the industry.
For example, in conventional mixers the mechanical systems are typically designed to
specifically avoid operating at resonance. This condition can quickly cause violent motions,
which leads to catastrophic failure of the system. However, when designed correctly a
mechanical system operating at resonance enables even small periodic driving forces to
produce large amplitudes of vibration that can be harnessed to produce useful work. For RAM,
this operating methodology is enabled through a system designed to conserve energy by
balancing kinetic and potential energy in a controlled resonant operating condition.
In the RAM systems, the potential energy is stored in the springs and the kinetic energy is kept
in the plates, or masses, that are coupled to the springs. The masses oscillate in a vertical

RAM5 Installation and
Operation Manual, Rev. 12.11.2012

motion, Figure 1. The
resonant frequency is
defined as the frequency at
which the mechanical
energy in the system can
be conserved between
potential energy stored in
the springs and as kinetic
energy in the moving
masses.
For the RAM technology, it
is the mixing system as a
whole that is operated at
mechanical resonance,
which is nominally at 60 Hz.
The exact frequency of
mechanical resonance
during mixing is only affected by the payload vessel (plus contents). The mix vessel contents
are termed the “Mixture”.
The resonant mechanical system is the “Mixer”. The mixer operates on mechanical resonance.
The mixture affects the mixers mechanical resonance frequency, by 1) the amount of material in
the mixing vessel, 2) how well the material couples to the vessel, and 3) how much energy the
mixture absorbs during mixing.
The amount of mixture mass affects the operating frequency because, as the payload mass
increases, the operating frequency decreases. Conversely, a lighter mass will produce a higher
operating frequency. The vessel weight, volume of contents, and specific gravity, are all
components of the “static” payload mass. If the mixture mass is fully coupled, i.e., riding along
with the vessel and not mixing, the resonant frequency will drop to the same frequency as if a
mass of equivalent weight as the mixture was added to the mixer. Conversely, if the material is
fully decoupled, i.e., not mixing, then the resonant frequency will become very close to that of an
empty vessel. However, for all conditions of coupling between the two extremes, the resonant
frequency will change depending on the amount of coupling.
Payload damping affects the amount of input force (intensity) required to accelerate the
payload. Damping is a difficult number to predict for materials. However, a general
understanding of what influences the amount of damping, and how damping affects the system
has been compiled, which will serve as talking points in this discussion. The primary factors
that affect damping are: 1) viscosity; 2) head space (amount of air or void in the mixing
container above the mixture), 3) internal mix vessel pressure (vacuum, partial vacuum, ambient
pressure, or pressurized); 4) temperature, and 5) vessel acceleration. Higher damping imposed
by the materials being mixed requires higher input forces (intensity) to achieve a specific
acceleration on the payload vessel. Damping is defined as the energy going into the mixture
during mixing.
Figure 1: Simplified representation of the mass, spring and damper
(mixing media) system that is in resonance.

RAM5 Installation and
Operation Manual, Rev. 12.11.2012
Resodyn Acoustic Mixers, Inc 8www.resodynmixers.com
Payload acceleration is a measure of the amount of acceleration imparted onto the mixture
vessel. It is measured in units of g. One g= 9.81 m/s2. Through mixing trials and experience,
the amount of acceleration required for a specific process will be determined. Higher damped
mixed materials, i.e., higher viscosity materials, will typically absorb more energy during mixing
than lower damped materials, i.e., low viscosity materials. As such, higher damping materials
typically require higher intensities to achieve the same payload acceleration compared to the
lower damped materials. The RAM5 mixer is controlled by setting the desired acceleration and
the mixer automatically controls the frequency and intensity.
The principle of
Resonance in
ResonantAcoustic®
Mixing is illustrated in
both Figure 1 (above)
and Figure 2.
ResonantAcoustic®
mixers are comprised of
multiple masses and
multiple springs, known
as a three-mass system,
that are simultaneously
moving during mixing.
The basic behavior of
the mixer is best understood by considering the simplified case shown in Figure 1, above.
The diagram in Figure 1, above, shows a mass moving with some velocity. In order to slow
down the mass (decelerate) there needs to be an applied external force. When the mass
decelerates, the lower velocity results in the mass having lower kinetic energy. Figure 1 shows
that a spring can store potential energy when an applied external force compresses, or
stretches the spring. The energy stored in the spring is greater when the deflection is large, and
reduces to zero when the spring is not distorted. The lower left diagram in Figure 1 provides a
representation of a spring-mass system. In this case, the “mixing” function is modeled as a
damper, which absorbs energy when the system is in motion. A second order non-homogenous
differential equation that describes the forces present during oscillation is shown in Figure 1,
lower right. This equation shows the relationship between the forces due to the moving masses,
the deflected springs, and the mixing process. The expression shows that these forces are
equal to the mechanical force driving the system.
The differential equation is repeated in Figure 2, and is coupled with the diagram to the left, as a
means to illustrate when resonance occurs. At a particular oscillation frequency, the resonant
frequency, the stored forces in the springs are directly offset by the inertia forces of the masses,
and cancel over one period of oscillation. Thus, the system can oscillate without the need for
charging the spring, or providing energy to the mass during the cycles. The plot on the left side
of Figure 2 graphically illustrates that for frequencies below resonance, energy is lost in
charging the springs, and above resonance energy has to be added to maintain the inertial
Figure 2: Differential equation and plots of oscillation amplitude and
power vs. frequency showing the benefit of resonance.

energy. The result of operating at resonance, as shown by the red and green curves, is that the
amplitude of the oscillations reaches a maximum, while the power required is at a minimum.
The power consumed by the system is transferred directly into the mixing media.
With the system oscillating at resonance, the acceleration of the load-plate imparts a boundary
condition on the vessel contents that is transmitted through the vessel contents as a pressure
wave. Energy used in creating the mixing movement will add to the damping of the overall
system, and the material contents will add to the mass. However, the amount of energy that
must be transferred into the materials in order to satisfy the boundary condition will be
dependent on a combination of many material and vessel geometry constraints. Some of these
constraints are: the height of column of material to be moved (vessel fill height), the
compressibility of the material, and its stickiness, or coupling of the material to the vessel walls,
material density, vessel geometry, internal vessel pressure, vessel percent fill, and mixing
regime.
Figure 3 displays the
resonant response of the
RAM mixer to variations in
a payload. The solid
black line represents a
payload that has been
accelerated to 100 g. Its
response is slightly over
61 Hz. Next, assume that
the payload mass is
constant but the payload
damping has increased.
The dashed gray line
shows how the same
input force (intensity) will
accelerate the payload to
lower accelerations (40 g).
The frequency drops
slightly from 61 Hz
because the mixture is
absorbing more acoustic
energy. If the same configuration is operated without any mix material, the dotted black line
shows a resonant shift to a higher frequency, slightly lower than 64 Hz. The shift is due to a
lower payload mass.
During the mixing operation, the mix media may transition through different regimes. A regime is
defined as mixing with a defined flow pattern. A regime change typically causes the materials
coupling with the payload vessel to change. Because a change in the coupling causes a shift in
the resonant frequency, a resonant tracking feature termed “Smart Mixing Technology” (SMT) is
included. SMT controls the mixer frequency and acceleration, which keeps the mixer operating
on the resonant peak at the desired preset acceleration.

System Overview
The RAM5 is a
ResonantAcoustic®mixer for
industrial applications. Figure 4
illustrates the main external
features of the RAM5. The
machine is composed of three
main components, which include
the Electrical Enclosure, Acoustic
Enclosure, and Resonator
(mixer).
Electrical Enclosure
The Electrical Enclosure, shown
in Figure 5, houses all of the
main electrical power and control
components. External features of
the electrical enclosure includes
the main power disconnect
switch, human-machine-interface
(HMI) computer, emergency stop
button, and lid open/close
pushbuttons.
The disconnect switch shuts
power off to the entire machine
and is defeatable and lockable.
The HMI computer and
pushbuttons located on the side
of the Electrical Enclosure serve
as the primary operator station.
The two-hand control
pushbuttons are used to open
and close the mixer lid. The HMI is a touch screen computer (Hazardous Location RAM5’s do
not have a touch screen) that allows the operator to enter desired mix parameters and monitor
machine operation and status.
The handle on the Electrical Enclosure allows access to the electrical components inside of the
enclosure for maintenance and inspection purposes. Note: This handle requires a key to
operate and gain access to the enclosure.
Only trained and qualified personnel should open Electrical
Enclosure doors.

Observe recommended Electro-Static Discharge mitigation best
practices.
Acoustic Enclosure
The Acoustic Enclosure
encloses the resonator
system. See Figure 6. The
enclosure reduces acoustic
emissions of the RAM5, and
covers moving parts that could
pose a risk to operators. A
hydraulically powered lid
provides access to the mixer
to load and unload mixing
containers. The hydraulic lid
is controlled from the
pushbuttons on the side of the
Electrical Enclosure.
Three access panels provide
for inspection and
maintenance. These panels
are removable via four quick
release compression clamps.
Resonator
The Resonator is the mixer itself. It consists of the metal plate masses, springs, eccentrics, and
drive system. The majority of the Resonator is enclosed by the Acoustic Enclosure. The only
visible part of the resonator is the point at which the mixing container is secured to the
Resonator. Several customer specific designs exist for mix containers and mix container
holders. Refer to the Supplemental Information package for mix container and mix container
holder specifics.
Figure 6: RAM5 Acoustic Enclosure and Resonator
Although the panels are interlocked, their removal poses a risk of
injury. Only trained and qualified personnel should remove side
panels of acoustic enclosure. Electrical power should be removed
from machine before accessing panels.

Operation – Quick Start
This section defines the minimum steps required to operate the machine. This assumes proper
installation of mix container holder fixture.
Setup
The following describes the necessary steps for preparing the machine for a mixing operation.
If configured for a dedicated chiller, ensure that the chiller unit’s main power switch is in
the “On” position. The Chiller requires a warm up period for the crankcase heater.
Read the Chiller (if equipped) manual before proceeding.
After the chiller warm-up period (if applicable) turn the System switch to the “Local”
position, which will turn the chiller and pump on.
The temperature setpoint for the chiller is 50 degrees Fahrenheit.
Turn the main disconnect switch (located on the Electrical Enclosure doors) to the “On”
position.
The Chiller cools the Electrical Enclosure. Always ensure the
Chiller is running if the Electrical Enclosure’s disconnect switch is
in the “On” position.
If your RAM5 is equipped with a Hazardous Location Option, please consult the Training Manual and Supplemental Information
for a description of the purge cycle that occurs at startup.
During initial startup the HMI computer will take a few minutes to boot-up.
To open the mixer lid, push both of the “Open” pushbuttons. Hold the pushbuttons down
until the lid stops opening.
Install the mix container. Ensure the container is properly clamped before proceeding.
Do not overload mix vessel, adherence to the maximum weight is
required for proper operation and machine life.
Close the mixer lid by pressing both “Close” pushbuttons. The HMI Computer will
provide indication when the lid is completely closed, at which point the “Close”
pushbuttons can be released.
HMI Operation
The HMI Computer is the primary user interface item on the RAM5. The RAM5 is completely
digitally controlled and most control (besides lid and optional hoist operation) is provided by the
HMI Computer. All data entry and operations are provided through software keypads and
buttons on the screen. The machine is controlled through the use of two operating modes,
which are referred to as Auto Mode and Recipe Mode. Recipe Mode should be the primary
mode used by operators, and will be covered in this section. Auto Mode is generally used by

RAM5 Installation and
Operation Manual, Rev. 12.11.2012
Resodyn Acoustic Mixers, Inc 17 www.resodynmixers.com
supervisors or technicians to characterize a mixing process, which will then be programmed as
a recipe for the operators. The Auto Mode will be covered in subsequent sections.
Do not use sharp objects on the touch screen. Sharp objects can
damage the touch screen.
Login
The first step for HMI operation is to login to the machine.
Login by pressing the Login button in the Navigation pane.
The “Login” dialog box will appear. To enter username, touch the username box. This
action will launch an alphanumeric keypad where username can be entered by touching
on-screen buttons, similar to the operation of standard PC keyboard.
Repeat this process for password entry and press the OK button when complete.
A login successful (or failure) dialog will appear after touching the OK button. Touch the
OK button on this dialog to complete the login process.
Press the Login button Enter username and password (touch textbox to enter
values through on-screen keypad)

Main Screen
There are two primary sets of screens associated with the RAM5 machine. These are referred
to as the Main Screen and the Setup, Configuration and Troubleshooting screen. The Main
Screen is the primary control screen where the Setup, Configuration and Troubleshooting
screen is used for maintenance, troubleshooting, and calibration. This section will discuss the
contents and operation of the Main Screen.
Certain features of the Main Screen will update depending on the operational mode selected,
current status, and the configured options for the RAM5 Mixer. While in recipe mode, the title
bar of the Main Screen will read “Recipe Mode”, and will read “Auto Mode” while in auto mode.
