METHOD AND DEVICE FOR PROCESSING OF WASTES Russian patent published in 2002 - IPC

FIELD: methods and devices for processing of wastes. SUBSTANCE: invention deals with processing of wastes subjected to several processing operations and their separation into different fractions. Method consists of at least the following operations: coarse cutting of wastes; separation of heavy substandard wastes in aqueous medium and removal of substandard wastes for further processing; crushing of standard wastes after separation of heavy substandard wastes and transportation of ground materials and fluid to pulper; dilution of said materials in pulper with their continuous at least periodical grounding; separation of suspension fully processed in pulper into different fractions and transportation, and further processing of obtained fractions. Device for method embodiment has cutting device, separator of heavy substandard wastes, crushers, pulper for dilution of material, device for separation of suspension and means for removal and processing of obtained fractions. Invention makes it possible to achieve more efficient processing of wastes and also to remove major part of heavy components from the process at early stage without formation of structures like ropes from thread-like components. EFFECT: higher efficiency. 11 cl, 3 dwg
