The KDS Micronex is a patented grinder-dryer which grinds and dries materials in a single-step process without needing any heat input. It is manufactured and sold by First American Scientific Corp. of Abbotsford, British Columbia. The KDS (Kinetic Disintegration System) was originally developed by Spectrasonic Disintegration Equipment Corp. and was licensed to First American Scientific Corp. from 1995 until 1999. 〔(【引用サイトリンク】 url=http://sec.gov/Archives/edgar/data/1002822/000100201400000146/0001002014-00-000146.txt )〕 First American Scientific Corp. purchased ownership of the KDS technology in 1999 and has since been awarded three American patents protecting its applications. The North American patents protecting the KDS technology are: Device and method for comminution - US Patent # (6,024,307 ) and Canadian Patent # (2,218,429 ) Cryogenic comminution of rubber - US Patent # (6,655,167 ) Method of recovery of precious metal & heavy minerals - US Patent # (6,682,005 ) Recovery of fuel and clay from a biomass - US Patent # (7,481,385 ) ==Grinding and drying characteristics== The KDS Micronex grinds materials that are fed onto spinning chains or bars located in a grinding chamber. Tip speeds of 200 m/s create high velocity airflows (4000 cfm)〔(【引用サイトリンク】 title=Pilot Testing of the Micronex™ System to Produce a Class A Biosolids )〕 and produce high velocity impacts when striking the materials being processed. A simultaneous drying event occurs because: -the repeated striking of the materials against the chains, baffle plates contained inside the grinding chamber, and against themselves create kinetic energy which heats the material -the high velocity impacts force moisture out of the material, and reduce particle size (increasing exposure to evaporating airflow) -the airflows created help to evaporate surface moisture and its airflows keep the particles suspended in air (allowing for air to flow over the complete surface area of the material) Once the materials reach a pre-determined size they will pass through an internal classifier. The classifier in the unit controls the particle size within the range between 30-325 Mesh (scale).〔(【引用サイトリンク】 title=Biomass Products & Technology )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KDS Micronex」の詳細全文を読む スポンサード リンク
