Abstract
Impregnating agents are concurrently processed with bulky materials such as recycled wastes within a turbulent fragmenting zone in order to fragment and uniformity impregnate the fragmented materials with impregnating agents. Uniform distribution of the impregnating agents throughout the processed materials may be accomplished by using multiple injection lines which port into the fragmenting zone at a position so as impregnate fluidized particles. Application of the impregnating agent is maintained at a substantially uniform pressure (e.g. porting from a manifold) so as to uniformity disperse and impregnate the impregnating agents throughout the processing material. The dispersal of the impregnating agent is effectuated by concurrently suspending fragmenting and impregnating the materials within the fragmenting zone 7. Recycled waste materials may be effectively impregnated with a host of impregnating agents such as application of pesticides, colorants, binding agents, insecticides, herbicides, etc. by the process. The impregnating process is particularly effective for use in impregnating cellulosic materials with multiple impregnating agents or colorants furnished to the fragmenting zone from the multiple sources at controlled and monitored rates. Conventional waste recycling machines may be appropriately equipped with the impregnating accessory for use in the impregnating process.
