CONCRETE SALVAGING PLANT Russian patent published in 2013 - IPC B09B3/00 B02C1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to concrete salvaging. Proposed plant comprises screen, electromagnet and water treatment system. Besides it includes three process flows. The first, preparatory flow includes hoppers to store mixes, concrete, bricks, asphalt delivered by motor transport. The second process flow comprises heavy metal screen, heavy metal trapping electromagnet, sand separator to bring the sand into hopper as a filler, impact crusher to separate concrete lumps from reinforcements coupled with the second electromagnet. The third, finish process flow consists of backup hopper coupled with impact reflecting mill coupled with the third electromagnet. Besides, it includes two screens coupled with water treatment system incorporating chipwood and organic component feed unit and fractionation unit wherefrom processed articles are directed to secondary filler warehouse.

EFFECT: higher efficiency of salvaging, improved environmental conditions.
