1.7 Guards and Safety Devices
Ensure all safety devices (limit switches, etc.) are functioning correctly, and regularly check their
operation.
1.8 Handling/Lifting
The LabRAM I mixer weighs 180 lb. (82 kg) with no vessel holder, payload, or additional
options. The mixer should be lifted by at least four (4) people, one on each side. The two
primary lifting positions are on the left and right-hand sides of the LabRAM I machine where
retractable, integral lifting handles are located (Figures 1 and 2 below). Two remaining
personnel can assist in lifting the LabRAM I mixer at the front and back base plate next to the
machine feet. Exercise caution when lifting and moving the LabRAM I to avoid striking other
objects.
There is ~1 ½” (~38 mm) clearance under the LabRAM I. This space allows clearance for
fingers, and for the retractable handles to be securely positioned under the machine when not in
use. The images below show the recommended locations for lifting the mixer using a
combination of base plate handholds and retractable handles.
Do not lift using any location other than the retractable handles and the mixer’s baseplate
handholds as indicated above. Lifting it any other way may cause damage to the LabRAM I
mixer and may result in personal injury.
The LabRAM I mixer weighs 180 lb. (82 kg) with no payload or
additional options. For safe lifting and transporting of the mixer, it
should be lifted by at least four (4) people via the handles and lift
points on each side, as shown below.

ResonantAcoustic® Mixing (RAM) Basics
Resodyn Acoustic Mixers 8 Rev. 072420
2 ResonantAcoustic® Mixing (RAM) Basics
ResonantAcoustic®Mixing (RAM) is an advanced mixing and processing technology that utilizes
low-frequency acoustic energy. The LabRAM I is an innovative approach to multiple mixing
applications from an initial pilot stage to production scale. These applications include powder-
powder systems, powder-liquid systems, liquid-gas systems, as well as combinations thereof.
RAM technology has also been adopted for use in many processing functions, such as coating,
degassing, grinding and sieving.
RAM Technology Delivers:
•Exceptionally uniform mixing and/or processing of virtually any materials.
•Significantly faster mixing and processing 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.
How RAM Works
The primary 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 way to describe this is the acceleration of gravity 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.
Acceleration is generated by the 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, and intense, yet generates 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. This 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 the energy from the system motors is
applied directly to the materials being mixed and/or processed, resulting in a highly 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

LabRAM I Installation and User Manual
ResonantAcoustic® Mixing (RAM) Basics
Resodyn Acoustic Mixers 9 Rev. 072420
materials’ properties in the processing vessel change, the impedance to the system changes as
well, requiring 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
The RAM 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
•processed material fill height of the vessel
•order of material added to the vessel for some processes.
For more information on the basics and practice of RAM technology, visit the Resodyn Acoustic
Mixers website at https://resodynmixers.com, or contact Technical Support (see Section 5
Technical Support).
How RAM Processing Scales
The processing settings used for the same material perform similar across all RAM technology
platforms, no matter the scale. This means that a finding of optimal settings on the bench scale
LabRAM I or LabRAM II mixer will be nominally equivalent to settings on the OmniRAM, RAM 5,
or RAM 55 mixers to process the same materials. As such, transitioning from discoveries made
in the laboratory to the pilot or production scale is seamless for most processes.

LabRAM I Installation and User Manual
Definitions
Resodyn Acoustic Mixers 10 Rev. 072420
3 Definitions
Acceleration: A change in velocity with respect to time that is expressed in “g.” Different
materials mix at different accelerations, based on the material properties and
other factors. (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 force
applied to the vessel and materials during mixing. For example, 10 gis 10
times the force of gravity. It may also be shown as g. Another term that may
be used to describe acceleration is “gravities.” (See “Acceleration” above.)
HMI: Human Machine Interface. The control and input system screen used to
operate RAM Mixers. Also called an operating system.
Headspace: The volume of compressible air, gas, or void space above the mixing media
in the vessel that is not occupied.
Impedance: See “Damping” above.
Mix Media: The material inside the mixing vessel.
Mixing Power: The amount of power being delivered by the RAM system to perform mixing.
Mixing Regime: This term identifies certain modes of mixing. The mixing regime defines the
bulk flow pattern of the ingredients 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
then across the top and down the sides. Another mixing regime, for example,
is characterized by a thick paste that does not couple with the vessel sides.
RAM: ResonantAcoustic®Mixing or ResonantAcoustic®Mixer.
RAMWare: Control software and its versions that run on a Personal Computer (PC) and
provides control to, and feedback from, the mixing process.
Resonance: The frequency (nominally 60 Hz) at which the RAM mechanical system
operates in the most efficient manner.
Vacuum: Internal vessel pressure that is less than atmospheric pressure

4 Installation
4.1 Unpacking, Lifting, and Placing LabRAM I
Upon receipt of the LabRAM I, do not unpack or remove any packaging materials until the
carton has been positioned as close to the installation location as possible. When in position,
remove all wrapping and strapping, and file shipping paperwork for your records.
Retain all packaging material for at least one year in case mixer transportation or shipment for
factory service is necessary. Original packaging is required for service shipment during the
warranty period and is highly recommended for any shipment performed during the life of the
product.
•Open the top of the box and remove any packing materials, bubble wrap, or other items.
When all packaging material is removed, slide the packaging box/sleeve up and over the
LabRAM I. The LabRAM I should be the only remaining item, resting on cushioning bags
in a corrugated tray on the shipping pallet.
•Make sure to remove any loose packaging material from the area, and check for tripping
hazards before attempting to move or install the LabRAM I.
•With a minimum of four people lifting at all four lifting locations, and using appropriate
safe lifting practices, lift the LabRAM I straight up and carry to its installation location.
See Section 1.8 Handling/Lifting on the previous page for lifting locations.
•When placing the LabRAM I at its location, allow enough room around the machine to
complete the installation, route wires and tubing, and allow for working space, etc.
The LabRAM I mixer weighs 180 lb. (82 kg) with no vessel holder
or additional options. For safe lifting and transporting of the mixer, it
should be lifted by at least four (4) people via the handles and lift
points on each side as shown in Section 1.8 Handling/Lifting on the
previous page.

4.2 Using the Retractable Handles
Retractable handles are located on both sides of the LabRAM I, installed in the base plate and
conveniently out of the way when not in use.
When you are prepared to lift and place the machine:
1. Locate the locking pins on either end of the handle brackets.
2. Pull straight down to release the locking pins while pulling the handles horizontally toward
you until they click-lock into the open, lifting position. Make sure the locked position is
attained before attempting to lift.
3. Reverse the procedure when the LabRAM I has been placed in its intended position. The
locking pins will automatically click-lock back in place when the handles are fully stowed
back under the machine. Make sure the locked position is attained before using the mixer.
4. Check for any blockage below the machine if the handles do not smoothly slide to their
locked storage position.
4.3 Mounting
The LabRAM I should be installed on a level, stable, and rigid surface capable of supporting the
machine weight of 180lbs (82kg) plus the weight of the vessel holder, vessel, and mix payload.
If other equipment or materials are to be placed or used on the same surface, a higher weight
rating should be used as appropriate.
ResonantAcoustic®Mixing (RAM) technology imparts near-zero forces in addition to the
machine’s weight to the surface on which it is mounted. Careful placement and leveling of the
surface by a qualified technician are recommended, as is a periodic inspection of the position
and condition of the surface. Surrounding instruments and accessories should be considered in
an overall placement plan. Contact Resodyn customer service with any questions regarding
appropriate mounting surfaces and your placement plan at [phone] or email
[email protected].

through software keypads and buttons on the screen. The touch screen and operating system
are described in detail in Section 9 HMI (Human Machine Interface) –Overview.
During operation the Payload Plate,
Cancellation Plate, Vessel Holder, and
Vessel move up and down rapidly,
accelerating up to 100 gat nominally
sixty times per second. Serious bodily
injury is possible if one comes into
contact with these moving surfaces.
