    LabRAM Users Manual – Revised 3/18/11 SAFETY INSTRUCTIONS 2.1 Types of Notices Throughout this manual you will find various types of safety notices. Their meanings are defined as: Warning – Indicates the possibility of a hazardous situation which, if not avoided, could result in injury or substantial property damage.

  • Page 4: Definitions

    LabRAM Users Manual – Revised 3/18/11 DEFINITIONS ® RAM. ResonantAcoustic Mixing SMT. Smart Mixing Technology; closed loop resonance tracking where the Power / Control Supply senses feedback from the mixer and controls the resonant response. RAMWare. Control software that runs on a Personal Computer (P.C.) and provides control to, and feedback from, the mixing process.

  • Page 5: Introduction To The Labram

    Intensity. A non-dimensional unit of Driver energy applied to the Resonator. Vacuum. Some pressure less than atmospheric. INTRODUCTION TO THE LabRAM Your LabRAM mixer is based on Resodyn Corporation’s ® ResonantAcoustic Mixing (RAM) technology. RAM mixing is distinctly different than conventional mixing methods such as impeller agitation.

  • Page 6: Major Components

    The overall assembly comprises: the Resonator, Cover, Umbilical Cables and Power Supply. Note: An optional Vessel Hold-down Fixture and a variety of vessel sizes are available from Resodyn Acoustic Mixers; see the ACCESSORIES Section 14 at the end of this Manual. Page 6...

  • Page 7: Resonator

    LabRAM Users Manual – Revised 3/18/11 5.2 Resonator The Resonator is the primary driver in your RAM mixer system. Your vessel, containing your mix media, attaches to the Top Plate. The Resonator, a powerful unit in a small package, works in a resonant mode to provide efficient energy transfer to the mix media in your vessel.
  • Page 8 LabRAM Users Manual – Revised 3/18/11 Cover. The Cover is cast acrylic. Its purpose is to contain fluid and debris if a vessel breaks during operation. A second purpose is to prevent a person from touching moving parts while the mixer is operating.

  • Page 9: Power Supply And Control

    LabRAM Users Manual – Revised 3/18/11 Power Supply and Control The Power Supply and Control is separate from the Resonator and can be located remotely, in order to minimize space occupied on your lab bench. The Power Supply provides power to the Resonator.
  • Page 10 LabRAM Users Manual – Revised 3/18/11 Main Power Switch. The Main Power Switch cycles power from the A.C. Power Entry socket. The switch may be left ON continuously. Power may then be switched ON or OFF at the Resonator switch. Note: Both power switches must be in the ON position for the machine to operate.

  • Page 11: Standard Vessel Fixture And Vessels

    5.4 Standard Vessel Fixture and Vessels Vessels of various sizes and a Hold-down Fixture are available through Resodyn Acoustic Mixers. Other vessel applications are adaptable to the LabRAM system. We can design a custom Hold- down Fixture to handle most any shape of vessel for your particular mixing application.

  • Page 12: Theory Of Ram Mixing

    LabRAM Users Manual – Revised 3/18/11 THEORY OF RAM MIXING ® ResonantAcoustics uses a proprietary method to create a mechanical system, designed to operate at a resonant frequency of ® the mechanical system. One advantage ResonantAcoustics over other mixing systems is the use of high-intensity acoustic energy.
  • Page 13 LabRAM Users Manual – Revised 3/18/11 Now that we’ve discussed how your payload affects the mixer, let’s look at the mixing process. The mixer operates at a mechanical frequency generally between 58 Hz and 65 Hz, and will accelerate a payload up to 100 G’s.

  • Page 14: Setup

    LabRAM Users Manual – Revised 3/18/11 mass causes a shift in the resonant frequency, we have built in a resonant tracking feature, “Smart Mixing Technology,” (SMT). SMT controls the mixer and keeps it operating on the resonant peak, even if the peak changes. You can also operate the mixer in a manual mode by turning off SMT.
