ABSTRACT:
Scrapped storage batteries are first preliminarily crushed to discharge acid from individual cells, thereupon rinsed by alkaline water, crushed in a hammermill and simulataneously dried by a stream of hot air; noncrushed lead pieces are discharged separately from the hammermill and the remaining crushed material is discharged in dry condition from the mill and classified into two fractions, namely a coarse lead fraction and a second fraction consisting of fine particles of lead compounds mixed with coarser pieces of plastic material.
