The results of determining the briquettes properties from fragments of the aluminum electric wire after the roller briquet- ting are presented. By increasing the relative cell depth by 50% compression ratio is reduced by 11%, therefore the strength of the drop is decreased by 13%. The compaction factor dependence, the density relationship of the rear and front ends of the briquette as well as the strength of the drop from the cells relative depth on the roll briquetting press are determined.
