Apparat til separation efter störrelse af partikler af kohæsivt materiale og fremgangsmåde

摘要

Milling/sizing apparatus which includes individual and/or nested sieves each of which may also include a quantity of beads, disks and/or other geometric or non-geometric shapes. The sieves can be rotated, vibrated or agitated in any and all combinations by various methods to achieve independently horizontal rotation and vertical reciprocation (similar to a merry-go-round) to efficiently segregate, size or mill cohesive and polydisperse powder particles to specific size ranges. The invention also contemplates a method for using the apparatus in the sizing and quantification of aggregated particles of cohesive disperse powders.
