摘要：
Process for pneumatic classification of mixture of granular particulates by providing an apparatus, entraining mixture, reducing velocity of entraining airstream, and airwashing falling particulates of low aerodynamic support. Specific applications include a method separating mixed granular material based upon dissimilar specific gravities, useful in cleaning firearm ranges by separating lead from backstop material. Falling granular lead particulates can also be airwashed and negative pressure facilitates control of lead dust. Also disclosed are applications that pick up and clean or enrich precious metal bearing ore, and a broad range of applications from heavy mixtures, such as landscape rock, to light mixtures such as grain.
