NOVELTY - The plant for the recovery of spent electric batteries, comprises crushing apparatus for the electric batteries, separating apparatus for batteries having grids and poles in which batteries placed downstream the crushing apparatus, low and high molecular weight plastic material from structures and separators, paste and electrolyte, semitraillers carrying the crushing (301) and separating apparatus (401), and loading apparatus for loading the batteries to the crushing and the loading apparatus that is carried on a second semitrailler.    USE - Used to recover lead-acid batteries and spent electric batteries.    ADVANTAGE - The plant is compact and cost effective. The plant recovers most components of the batteries.    DETAILED DESCRIPTION - The plant for the recovery of spent electric batteries, comprises crushing apparatus for the electric batteries, separating apparatus for batteries having grids and poles in which batteries placed downstream the crushing apparatus, low and high molecular weight plastic material from structures and separators, paste and electrolyte, semitraillers carrying the crushing (301) and separating apparatus (401), and loading apparatus for loading the batteries to the crushing and the loading apparatus that is carried on a second semitrailler. The crushing apparatus has a hopper (303) in which batteries are loaded, a hammer mill (305) for crushing the batteries and a transferring screw conveyor (307) transfers the crushed batteries to the separating apparatus. The hopper of the crushing apparatus is detachably fastened to the mill to remove from the mill when the plant is at rest. The grids and poles separating apparatus comprise a rough gravimetric separator of dynamic type, such as cyclone separator, and fine separator and e.g. screw conveyor type. The low and high molecular weight plastic materials separating apparatus has gravimetric separator, e.g. flotation separator. The paste separating apparatus has a circuit for re-circulating water with pump, screening diaphragms and settling tank along the circuit, scraping chain passes the tank for removing the paste, a dehydrating screw conveyor and an extracting device e.g. chain type. The electrolyte separating apparatus has a circuit for draining water with pump and a knit mesh filter along the draining circuit. The hopper, the body and coatings of the mill, transferring screw conveyor, rough gravimetric separator and the fine separator, the gravimetric separator, the settling tank, the dehydrating screw conveyor, and the extracting device are stainless steel. The hammers of the mill are thermally treated austenitic-ferritic alloy and the knit mesh filter is polypropylene fabric. The semitrailler provides with collecting tanks below the crushing and separating apparatus and telescopic supports. The loading apparatus has hopper with measuring and extracting device, and telescopic conveyor belt extends to the crushing apparatus and magnetic separator adjacent to the belt. The telescopic conveyor belt connects to the second semitrailler folds and removes when the plant is at rest. The telescopic conveyor belt extends in orthogonal direction to the longitudinal axis of the second semitrailler and semitraillers are orthogonal to each other. The telescopic conveyor belt extends in parallel direction to the longitudinal axis of the second semitrailler and semitraillers are lined up with each other. The magnetic separator extracts foreign bodies of ferrous materials from the batteries to the belt. The second semitrailler provides collecting tanks below the loading apparatus, purifying device or scrubber and telescopic supports. The second and third semitrailler transports electronic and/or mechanical equipment having power generating set for power-supply and control of the plant. An INDEPENDENT CLAIM is included for method for the recovery of spent electric batteries.
