7. RAM Basic Technology Overview
Mixing System
• Sound Energy Generator
• Mechanical vibrating system
• Exchange of potential and kinetic Energy
between moving plates and springs
• Operates at resonance for maximum
efficiency
Mixing Processes
• Non-Contact Mixing
• No blades, impellers, or engineered
devices
• Sound energy drives the mixing process
• Efficient mixing energy distribution

Sound Wave Propagates through Medium in Contact with the
Base Transducer at the Excitation Frequency

15. Conventional Mixing
Movement of Bulk Materials
throughout the Vessel is Required
to Drive the Unmixed Materials
through the Intense Mixing Zones
Intense Mixing Generally Localized
to the Regions Near the Impeller
Tips
Flow of the Bulk Materials around
the Vessel into the Intense Mixing
Zones near the Impeller requires
Time and Energy that is not
Substantially Contributing to Mixing

Solids Mixing
Vertical Vessel Movement Sets the Particles in
Motion When They Collide with the Vessel Bottom
The Primary Mixing Mechanism Is Particle
Redistribution Driven by Inter-Particle Collisions
Mixing Occurs Through Random Particle Motion

Two Types of Tumble Blenders
using Similar Modes of Mixing
• V-Blender
• Cone-Blender

RPM
1 g
There are two Modes of
Combining Solid-Solid Materials
in Tumble Blenders:
1. Diffusion Blending 2. Bulk Mixing
Uses gravity (1 g) only, drive
small scale random motion
during particle cascading
Each rotation (~30 RPM)
simply splits and recombines
material cyclically
RAM
Comparison
Uses up to 100 g to drive
chaotic particle motion
RAM 60 Hz mix cycle (~3,600
RPM) uses intense chaotic
motion and prevents
de-mixing

24. ◼ Mixing with Conventional
Propellers or Impellers Requires
• Careful consideration of the
materials being mixed
• Use of specific mixing hardware
designs to enable effective mixing
◼ Materials Can Clump/Cling/
Segregate Creating Dead Zones
◼ Complex Mixer Configurations
Can Include Addition of Wall
Scrapers, Additional Impellers, etc.
◼ Time Dependent Process
Constraints Often Prevail
Conventional Mixing - Complex and Varied Hardware
