Effects of The Type of Sub-Head and Blade Crushing Speeds of a Hammer Mill on The Performance Size Reduction of Sugarcane Leaves
Keywords:
Sugarcane leaves, Hammer mill, Size reductionAbstract
The objective of this study was to determine the effects of the type of sub-head and speed of blades of a hammer mill on the performance size reduction of sugarcane leaves. The Khon Kaen 3 various sugarcane leaves with an average moisture content of 10.36 % (wet basis) were used in this study. The experiments were conducted using 2 different the type of sub-head of type A and type B and at the blade crushing speeds of 800, 900, 1,000 and 1,100 rpm. The results revealed that type of sub-head and blade crushing speeds significantly affected working capacity, power consumption, specific energy and geometric mean particle length of the sugarcane leaves. The type B sub-head is more suitable for reducing sugarcane leaves than type A. At the blade crushing speeds of 1,100 rpm and the type B sub-head, the percent crush was 76.30 %, the working capacity was 22.89 kg/hr, the power consumption was 1,136.69 watts, the specific energy was 49.64 W-hr/kg and geometric mean particle length was 0.633 mm.
