RAM MIXES SOLIDS
10X FASTER AND MORE UNIFORMLY
Powders of nearly any size, material characteristic, or morphology are rapidly and thoroughly mixed using RAM technology. Additionally, RAM processing is frequently orders of magnitude faster than traditional technologies.
The RAM platforms's rapid, 60Hz motion causes each particle to randomly collide with adjacent particles, diverting their paths, colliding and re-colliding with other particles behaving in equally chaotic fashion.
Similar or Dissimilar Particle Sizes
Chaotic particle collision and large scale vapor migration speed dispersion and ultra-high uniformity.
Static and other physical forces combine to thoroughly coat particles, one material on another, layer upon layer.
Agglomerated materials are separated into uniform particles that are segregated rapidly with sieving attachments.
Milling, Size, & Morphology Changes
With the selection and addition of appropriate milling media, RAM can also be used to reduce particle size or change particle morphology.
RAM technology can be used to separate mixed particles of varying sizes using common sieves. Low frequency operation speeds separation and flow-through of particles to cleanly and thoroughly segregate particles.
HOW RAM MIXING
The Mechanics of RAM Mixing
RAM technology drives particle to particle collision and generates large-scale vapor migration, vastly improving both modes of powder mixing.
- Vertical vessel movement 60 times per second at up to 100 g of acceleration generates intense particle motion
- The primary mixing mechanism is particle redistribution driven by inter-particle collisions
- Particle motion is entirely random, preventing de-mixing
- Active vapor pockets move rapidly throughout the powder matrix creating highly active mixing zones
How RAM Compares to other Methods
At small scale, diffusion blending
At scale, bulk mixing blending
Traditional tumbling methods use a single g of gravity to circulate mixing powders in small scale particle cascading
Using less than 30 rpm, traditional methods must avoid centripetal motion to keep particles involved in mixing
RAM generates up to 100 g of acceleration driving chaotic motion through the mixing media
RAM uses intense chaotic motion without any centripetal forces or de-mixing phenomena

SOLIDS MIXING WITH RAM
Dissimilar Powder Mixing
Dry ingredients can be difficult to thoroughly and consistently mix, particularly when the particles are of different sizes and characteristics. To illustrate effective and rapid mixing, 10 grams of fumed silica is blended with 100 grams of sand. Completed specimens exhibit no airborne fumed silica, demonstrating uniform blending at an order of magnitude difference in particle size.
Milling and Nano Coating
Coating larger particles with smaller ones is a common processing application, and milling is often a part of the same process. In this video, agglomerated carbon black particles are simultaneously milled to nano size particles that coat the plastic pellets completely in just a few seconds. The high speed video clearly illustrates the dispersion of carbon black particles, their de-agglomeration, and progressive and comprehensive coating of the plastic pellets.
