METHOD AND DEVICE FOR PRIMARY PROCESSING OF MATERIALS Russian patent published in 2013 - IPC B29B17/04 B02C18/08 B02C23/26 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to primary processing of a lump or particles of material displacing or rotating, being mixed, heated or ground by mixer (12, 21) in intake container or cutting compressor (1). Undesirable impurities that can hamper primary of further processing are removed from the material. Note herein zone under material processed in intake container (1) or under material level of mixing swirl. Gas is forced inside intake container (1), in particular, air or inert gas. Note here that gas is forced by flow through at least the material portion. Gas enriched or saturated with admixtures in zone above material processed in intake container (1) or above material level of mixing swirl is discharged from intake container (1). Note also that gas is forced into intake container in zone above mixer (12) arranged close to the bottom or in zone between mixer (12, 21).

EFFECT: uniform temperature and pre-compaction.
