We did a study, aiming to investigate the optimum binder and moisture conditions required to produce a mechanically strong briquette using two different binders – a PVA powder (binder A) and a starch powder (binder B). It was found that for binder A, the optimum moisture level was 12% to 14%. At this moisture level the greatest compression strength gains were observed, and low amount of fines produced in impact and abrasion tests. The minimum amount of binder added while still obtaining a strong briquette was 0.5% binder A. For binder B, the optimum moisture level was also 12% and the minimum amount of binder B to be added was found to be 2%.
