We provide particle size analysis using various techniques but we do not perform particle counting. Please click on the following link for information regarding particle-counting services: Interbasic Resources, Inc www.ibr-usa.com. We receive many questions regarding ISO, SAE and AC Test Dusts. For answers to most of these questions please read the “Test Dust History”
Jet milling: Particle sizes attained from jet milling are as low as a 4-micron median to as high as a 45-micron median. Jet milling is best suited for distributions ranging from 0-150 microns. Hammer milling: Best suited for coarser distributions ranging from as low as ~20 microns up to ~ 2000 microns. Vibratory screening: Screen sizes from 38 – 4800 microns are available. Air classification: Particle size distributions as tight as nominal 0-3 microns and as broad as nominal 0-45 microns can be achieved. Jaw crushing: Primarily used as a pre-crushing step for material that is too large to feed into a secondary mill, such as a jet mill or hammer mill. Our jaw crusher can reduce material as large as 5” x 7” down to minus 10 mesh in one pass.
