6. Introduction to Grading Technology
6. Mastering Ultimate Classification Technology: Complete Removal of Coarse Particles Not Reflected in Particle Size Distribution - In recent years, the development of fine particles and their applications has rapidly expanded, with many companies exploring new business opportunities related to material types, particle sizes, and shapes (as observed at the Powder Technology Exhibition). - While very sharp particle size distributions are required for certain applications, completely removing coarse particles that are mixed during the manufacturing process and meeting stringent specifications is an extremely challenging task. - Semtech Engineering has developed a super high aspect ratio, ultra-reliable "sieve" Challenging particle size classification technology for particles below 5 μm using the "Super Micro Sieve." - With a minimum hole diameter of 5 μm, we have successfully achieved complete removal of coarse particles larger than 5 μm mixed during the manufacturing process at the PPB level. We have also succeeded in developing a mass production wet classification device, S-150W.
