Powders of nearly any size, material characteristic, or morphology are rapidly and thoroughly mixed using RAM technology. The RAM platforms rapid, 60Hz per second 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 to create exceptional homogeneity in powders regardless of their size or characteristics. RAM Blends the Most Difficult to Mix Powders with Exceptional Homogeneity - Cohesive, Fine Powders & Metal Powders - Low-Dose API / High-Potency Blends - Multi-Component / Density-Mismatched Blends - Dry Powder / Particle Coating - Heat-Sensitive or Shear-Sensitive Materials Similar or Dissimilar Particle Sizes Chaotic particle collision and large scale vapor migration speed dispersion and ultra-high uniformity. Dry Powder Coating Static and other physical forces combine to thoroughly coat particles, one material on another, layer upon layer. Deagglomeration 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. Sieving 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. RAM technology drives particle to particle collision and generates large-scale vapor migration, vastly improving both modes of powder mixing. ResonantAcoustic® 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 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 Dissimilar Powder Mixing In 10 Seconds! 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 in only 10 seconds. Completed specimens exhibit no airborne fumed silica, demonstrating uniform blending at an order of magnitude difference in particle size. Milling and Nano Coating in 8 Seconds! 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. NASA Invents GRX-810 SuperAlloy with RAM GRX-810 is made by coating NiCoCr metal powder with a film of nanoscale Y2O3 oxide particles using RAM technology. Prior attempts to mechanically alloy the Y2O3 onto the metal powder with traditional equipment had deformed the powder. It became more platelet-like, had a tendency to stick, and as a result was much more difficult to print. RAM rapidly and powerfully, yet gently coats the metal powder with the ceramic, without deforming the powder. The powder remains very spherical and flows well through the 3D printer.
