Abstract

Scrap or waste materials, esp. wrecked motor cars and tyres, are cooled to a low temp. by a liquid gas and then crushed and the liquid gas evaporated during cooling of the scrap is a least partially cooled by heat exchange with the crushed scrap and recycled into the circuit of the scrap to be crushed. This reduces consumption of liquid gas.
