This research aimed to study physical characteristics of caking of sugar in sacks, the compressive that caused sugar cracking and elements in threshers design that caused to efficient sugar cracking in the way that a thresher design has a similarity of spur gear. Experimental factors consist of 3 levels of a height of rasp – bar type thresher as 0.5, 1.0 and 1.5 inches and linear velocity of threshers as 0.086, 0.105 and 0.123 meters per second. According to the results, it was found that the Rasp - bar type a height of 1 inch and linear velocity of threshers as 0.105 meters per second affected 40.35 kilopascals of compressive stress, 15.83 kilopascal of shear stress and 6.03 new ton meters of torsional moment. Experimental results of sugar sacks compression found that an average of hardness test was equal to 50.5 brinells which revealed that levels of rasp - bar type threshers have an effect on functions of sugar sack-threshing machine. A suitable height range of rasp – bar type thresher was 1 inch. Higher levels had no effect on more sugar dissolving. However, scales of compressive stress of  rasp – bar type thresher on sugar sacks increased in the opposite way.
