LabRAM II Operations Manual
Introduction
Resodyn Acoustic Mixers 1 Revision 063020
1 Introduction
The LabRAM II is an advanced, low-frequency, acoustic mixer. It is the second generation of
ResonantAcoustic®Mixers LabRAM, an innovative approach to multiple mixing applications.
These applications include powder-powder systems, liquids, creams, highly viscous gels and
pastes, as well as sieving and grinding (with the proper vessels and attachments).
RAM mixing provides:
•Exceptionally uniform mixing across a broad range of materials.
•Significantly shorter mixing times than traditional methods.
•Completely sealed, dust-free mixing process resulting in enhanced operator safety.
•Highly repeatable results from mix-to-mix, ensuring batch-to-batch product quality.
ResonantAcoustic®Mixing (RAM) and Acceleration
The primary driving mechanism that creates mixing by the ResonantAcoustic®Mixing (RAM)
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 more 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: gn, defined
as ~9.81 meters per second squared.
Acceleration is the driving mechanism for acoustic mixing, stated in units of the acceleration of
standard gravity - or g- as outlined above. For example, a heavily loaded mixture of solids with
a viscous liquid may be best mixed at an Acceleration of 80 g, or 80 times the force of gravity.
The correct level of Acceleration, or gcreates micro-mixing zones that liquids and viscous
materials require, and creates the chaotic collision phenomenon that effectively mixes solids
and powders. The process of determining an optimal Acceleration, or gto obtain the best
mixing is an iterative one, arrived at through observation, optimization, and product quality
testing. Resodyn Acoustic Mixers process engineers and technical sales staff are always
available to provide assistance in this process.
Furthermore, Acceleration or gis measured the same way across all RAM technology
platforms. So, 50 gon the LabRAM mixer is equivalent to 50 gon the RAM 5 or RAM 55 mixers.
It is also important to note that, while mechanical devices typically rely on increasing the power
to improve mixing, better mixing with RAM technology is not necessarily the result of more
power. Instead, the quality of mixing is the result of the right combination of energy applied to
the materials - in the form of Acceleration or g- for an adequate amount of time. Therefore,
some materials may be best mixed at a lower level of Acceleration.

LabRAM II Operations Manual
Definitions
Resodyn Acoustic Mixers 2 Revision 063020
2 Definitions
Acceleration: A change in velocity with respect to time that is expressed in “g.” Different mix
media mixes at different accelerations, based on the material and the
expected results. (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 mix media 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 the acceleration is “gravities.” (See
“Acceleration” above.)
HMI: Human Machine Interface. The control and input system screen used to
operate the LabRAM.
Headspace: The volume of compressible air, gas, or void space above the mixing media
in the vessel that is not occupied.
Mixing Media: Defined as 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 mix 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 mixing regime is when the flow
pattern is reversed and the flow comes up the vessel sides and down the
center of the vessel.
RAM: ResonantAcoustic®Mixing or ResonantAcoustic®Mixer.
RAMWare: Control software that runs on a Personal Computer (PC) and provides control
to, and feedback from, the mixing process. (Also RAMware2.)
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.

3 Safety
Every effort has been made to assure that the LabRAM II is easy to use, reliable, and safe. This
section outlines the general safety considerations and defines caution and warning symbols
used throughout this manual.
3.1 General Safety Considerations
For safe operation, the LabRAM II should be operated only within the limits outlined in the
system specifications. The following classification defines acceptable use for the LabRAM II.
•Indoor use only.
•Main supply voltage fluctuations are not to exceed ±10% of the nominal supply
voltage.
•This equipment is suitable for continuous operation.
•For use in non-hazardous environments as classified by the United States National
Electrical Code (NEC).
3.2 Warnings and Cautions
Throughout the manual, the following symbols are used to identify warnings and cautions:
The caution symbol indicates a potential hazardous situation which could result in
minor injury or damage to the product.
The high voltage symbol indicates the possibility of electrical shock.
This symbol means turn off the electrical supply before removing any cover with
the symbol attached. Failure to do so may cause exposure to electrical shock
hazard.
Access to electrical components should only be carried out by a licensed
electrician or qualified electrical engineer.
NEVER attempt to modify any electrical components or circuits as this may affect
the safe operation of the machine.
Electrostatic Discharge (ESD) sensitive components.

3.3 Important Safety Notes
This equipment should only be operated by trained and qualified personnel.
Mixing operations can generate heat and internal pressure depending on material
and mixer accelerations. Do not mix materials longer than what has been
characterized as safe.
Do not attempt to run the machine without a mix container holder. Equipment
damage may result.
Do not disable or tamper with any safety items, such as safety interlock switches
located on the LabRAM II system.
Note: Changes in noise level or frequency are common during mixing operations. If
rattling, metal-on-metal, or obnoxious noises occur, turn off the LabRAM II and call
or email the Resodyn Acoustic Mixers Technical Support.
3.4 Location Advisory
3.5 Component Replacement
The system is designed with components that are specifically rated for use with the LabRAM II
machine. Only replace worn or damaged components with direct factory replacement parts or
parts approved by Resodyn Acoustic Mixers. Incorrect component replacement can impair the
safety of the equipment and risk injury to personnel.
3.6 Customer Responsibility
•Ensure that all operators have received the correct training to operate the mixer.
•Ensure that all operators have read and understood this instruction manual.
•Ensure that a qualified electrician carries out any electrical maintenance.
The LabRAM II system is designed to be operated in non-hazardous environments.
The LabRAM II system is protected by an IP20 enclosure which is not rated for
operation in dusty environments.

3.7 Handling/Lifting
The LabRAM II mixer weighs 260 lbs. with no additional options. The mixer should be lifted by
at least 4 people, one on each side.
The two primary lifting positions are on either side of the LabRAM II machine where retractable,
integral lifting handles are located (Figure 1 below). Always exercise caution when lifting and
moving the LabRAM II to avoid striking other objects.
Two remaining personnel can assist in lifting the LabRAM mixer at the remaining two sides next
to the machine feet. There is ~1 ½” clearance under the LabRAM II. This space allows the
retractable handles to be securely positioned under the machine when not in use. The LabRAM
II mixer should be lifted, at the locations indicated below, by at least 4 people, positioned at
each side of the machine as designated by circles in the diagram below. The arrows show the
recommended locations to place the hands for lifting the machine using a combination of base
plate hand-holds and base plate retractable handles.
Figure 2 shows the underside of the mixer indicating the recommended location of the hands for
lifting and carrying the LabRAM II machine using retractable handles.
Do not lift using any location other than the retractable handles of the mixer’s baseplate and the
hand holds as indicated above. Doing so may cause damage and failure of the LabRAM II
machine and may cause injury.
For safe lifting and transporting of the mixer, the mixer should be
lifted by at least 4 people, one on each side as shown above.
