1 Introduction
ResonantAcoustic® Mixing (RAM) is an advanced mixing/processing technology that is the only
technology that uses low-frequency acoustic energy for mixing and processing. The RAM 5 is
an innovative approach to multiple mixing applications from pilot to production scale. These
applications include powder-powder systems, powder-liquid systems and liquid-gas systems, as
well as combinations thereof. The technology has also been adopted for use in many
processing functions, such as coating, degassing, grinding and sieving.
The RAM system provides:
•Exceptionally uniform mixing and/or processing of virtually any materials.
•Significantly faster mixing and processing times than traditional methods.
•Completely sealed, dust-free process resulting in cleanliness and enhanced operator
safety.
•Highly repeatable results, ensuring batch-to-batch product consistency and quality.
•The ability to process materials not possible by other methods.
RAM Operations
The primary driving mechanical driver of RAM mixing technology is Acceleration (rate of change
of velocity). The unit of measure of acceleration in the International System of Units (SI) is
meters per second squared or m/s2. A familiar way to describe this phenomenon is the
acceleration of gravity here on earth or g. One gis the acceleration of gravity at the Earth's
surface and uses the standard gravity symbol: g, defined as ~9.81 meters per second squared.
The acceleration is generated by vertical motion of the mixing/processing vessel configured in a
RAM machine. This vertical, sinusoidal motion operates at a frequency of between 58 and 62
Hz and at a peak displacement of up to 0.55” when operated at 100 g. The combined low-
frequency vibration and resulting displacement creates a physical mixing and processing motion
that is, uniform, repeatable, intense, yet low shear.
All RAM systems operate at this frequency range in a resonant condition, which enables a
process that requires low levels of energy for operation. The resonant condition of the system is
established over a range of frequencies that enables a balance between the kinetic energy of
the springs and potential energy of the oscillating plates that comprise the resonator platform.
The materials being mixed are the impedance for the resonant system.
When the system is operating at resonance, virtually all of the energy from the system motors is
applied directly to the materials being mixed and/or processed, resulting in a very energy
efficient system. This resonant condition is frequency dependent and requires the frequency to
allow a near perfect balance between the kinetic energy forces, the potential energy forces and
the impedance of the process. Both the kinetic and potential energy forces are set by the
system design, but the impedance depends upon the nature of the process that is contained in
the mixing/processing vessel that is agitated by the plate/spring resonator. Moreover, as the
materials properties in the processing vessel change properties the impedance to the system

4
Resodyn Acoustic Mixers Rev 062520
changes, which requires careful control and adjustment of the system frequency in order to
keep the RAM system at resonance. This operating frequency is automatically sensed and
controlled by a proprietary system/methodology that is an integral feature of the RAM
technology. The system/methodology continuously and automatically adjusts to changes in the
mixing/processing conditions within the mixing vessel or processing container. The continuous
maintenance of the resonant operation provides both power and economy to all RAM devices.
RAM Processing Parameters
RAM’s mixing platform’s intense vertical motion also generates acoustic effects within the
mixing vessel. This “sound mixing” has different effects on different materials that are being
processed.
In addition to the vessel acceleration, g, other salient factors that affect the mixing and/or
processing performance include pressure inside of the mixing/processing vessel (which can
range from vacuum to pressurized), temperature of the vessel contents, vessel design and
processed material fill height of the vessel, as well as order of material addition to the vessel for
some processes.
For more information on the basics and practice of RAM technology, visit the Resodyn website
at www.https//ResodynMixers.com, or contact Resodyn at 406 497-5333.
RAM Product Line
When considering the entire RAM product family, it is important to recognize that, generally
speaking, the processing settings used for a particular material performs the similarly across all
RAM technology platforms. This means that a finding of optimal settings on the bench scale
LabRAM I or LabRAM II mixers is nominally equivalent to those that would be used to process
the same materials on the OmniRAM, RAM 5, or RAM 55 mixers. As such, transition from
discoveries made in the laboratory to the pilot, or product scale are seamless for most
processes.

2 Definitions
Acceleration: A change in velocity with respect to time that is expressed in terms of “g.”
Different ingredients mix at different accelerations, based on the material and
other processing variables. (See “g” below.)
Damping: A term to quantify the instantaneous amount of energy absorbed by the mix
media while mixing
g: A measure of acceleration expressed as a multiple of the gravitational
acceleration applied to the vessel and its ingredients during mixing. For
example, 10 gis 10 times the force of gravity. Other terms are “g” and
“gravities.” (See “Acceleration” above.)
HMI: Human Machine Interface. The control and input system screen used to
operate RAM devices
Headspace: The volume of compressible air, gas, or void space that is otherwise not
occupied above the mixing media in the vessel
Millibar Or mbar, is unit of air pressure in the metric system based on an absolute
scale. This method displays the same measure regardless of altitude
Mixing Ingredients: Defined as the material inside the mixing vessel
Mixing Power: The amount of power being delivered by the RAM system to perform mixing
in terms of watts per kilograms
Mixing Regime: This term identifies certain modes of mixing. The mixing regime defines the
bulk flow pattern of the media during mixing. A regime changes when the bulk
patterns change. For example, a stable fluid mixing regime for thick pastes
would be one that flows from the bottom of the vessel up the center and then
across the top and down the sides. Another regime is indicated by a paste
mix that is fully coupled to the sides of the mixing vessel and does not move.

Additional options for the LabRAM II H are heating and cooling plumbing for a jacketed vessel,
vacuum control, remote USB access and temperature monitoring, as well as custom vessel
fixtures, and other custom options.
4.1 ResonantAcoustic®Mixing Platform
The LabRAM II H delivers energy to the material being mixed by accelerating the platform up to
100 gof acceleration, as well as the sound energy created by that motion.
4.2 Acoustic Enclosure
The acoustic enclosure surrounds the patented resonator system. The enclosure reduces the
sound emitted by the LabRAM II H but does not cover the upper resonator plates and gaskets.
Because the moving parts on top of the resonator are not contained in the acoustic enclosure,
the movement of these plates could pose a risk to operators and also generates sound above
80 dB at the machine.
During operation the Payload Plate, Driver Plate, Fixture, and Vessel are accelerating
up to 100 gof acceleration at nominally sixty times per second (60 Hz). Serious bodily
injury is possible if one comes into contact with these moving surfaces.
4.3 Remote Panel and Touch Screen Human Machine Interface (HMI)
The remote panel HMI is the primary user interface on the LabRAM II H. The LabRAM II H is
digitally controlled through the HMI. All data entry and operations are provided through software
keypads and buttons on the screen. The touch screen and operating system is described below

4.4 Standard Vessel Fixture and Vessels
A variety of vessel sizes and types, along with the appropriate hold-down fixtures are available
for the LabRAM II H. The standard and supplied vessel hold-down fixture is a 5” diameter vessel
holder that accommodates vessels between the heights of 4.5” and 7”. For vessels shorter than
4.5”, spacers can be purchased from Resodyn Acoustic Mixers as well as shorter standoffs and
bolts that will accommodate vessel heights between 2.5” and 5.25”. Many applications call for
specialized, custom hold-down fixtures. Resodyn can provide virtually any shape of vessel a
particular mixing application requires. Please contact your Resodyn Acoustic Mixer sales
representative to learn more. [phone]
The LabRAM II H hold-down fixture is made of several key components. All components are
made from electrically conductive or static dissipative materials. These are the hold-down knob,
jam nut, cross bar, bolts, standoffs, upper base, lower base, and upper and lower dots shown
above in sequence and described in more detail below.
Hold-down Knob. Turning the Hold-down Knob clockwise clamps the vessel in place. The knob
is coupled to specialized thread designed for strength and accuracy. The thread is connected to
the Upper Base. Turning the knob raises and lowers the Upper Base.
Jam Nut. The Jam Nut is used to lock the vessel in place. When tightened against the top of the
Cross Bar, the Jam Nut locks the Hold-down Knob from loosening during operation. The Jam
Nut is set after the mixing vessel is tightened down using the Hold-down Knob.
Vessel Spacer Vessel Spacers (not shown) accommodate smaller vessel heights in the
standard height vessel holder. Shorter vessels may require one or more spacers stacked
together. Any mixing vessel must be securely positioned within the upper and lower bases of
the hold-down fixture by RAM Vessel Spacers only. If the mixing vessel is not secure in the
vessel holder, damage may occur to the machine, vessel, and the mixing material. If you require
vessel spacers, please contact your Resodyn Acoustic Mixers sales representative. (405) 497-

Fixture and Vessel from loosening during operation. 8 ft-lbs. is the recommended
torque setting. No audible sound should be heard from any of the Vessel Holder
Components
All Vessel Holder assemblies, standard or custom, will match a hole pattern in the Top Plate.
Mounting hole pattern for the standard 5” vessel holder is ¼-20 threads measuring 5.75” center-
to-center.
The mounting plate that comes standard with the LabRAM II H also has mounting holes to
accept fixtures and vessels from the original LabRAM. The fastener holes are four ¼-20 threads
measuring 4.375” center-to-center.
See the detailed illustration on the next page for the position of these mounting holes.
Note: When the LabRAM Mounting holes are not in use, brass set screws should be
installed to seal the purge gas from excessively leaking through the open fastener
holes. Silicone may be added to the outside of the setscrews to create an airtight
seal. However, a LabRAM II H mounting plate is available without the LabRAM
Mounting holes (Resodyn Part Number 102786).

6.5 Purge System
The LabRAM II H uses a remotely mounted Purge and Pressurization System. The purge
control unit should be mounted near the LabRAM II H. Please refer to the Pepperl+Fuchs 6000
Series Purge/Pressurization System manual for guidance on mounting the purge control unit.
The unit has three electrical connections: incoming power, power going to the LabRAM II H, and
an intrinsically safe cable that connects to the purge vent (the included cable is 16.4 ft (5m)
long). It also has two pneumatic connections: incoming supply, and purge air going to the
LabRAM II H. The purge air must be clean and dry; see Table 6-1 for the exact requirements.
Wiring, plumbing and operating the purge control unit can be found in the unit’s manual. All
wiring shall be rated for the hazardous location and installed by a qualified electrician. The
electrical source and fuses should be rated for the supply power for your area. The ratings for
both voltage ranges are as follows: 8 Amps for 100-120 VAC and 6.3 Amps for 200-240 VAC.

If required, the purge control unit can be operated in "Bypass Mode" which maintains power to
the LabRAM II H if the purge pressure is lost. The unit’s manual provides directions to activate
this setting. Activate the Bypass Mode for startup and maintenance purposes. When the
Bypass Mode is active, the safety power shut off function is disabled! Do not activate the
