2.2.2 Dural tester
Figure 2.2 is a picture of the Dural. Initially, the prototype was designed in the Agricultural Process Engineering Laboratory, University of Saskatchewan (Larsen et al., 1996). The Dural was later developed to simulate these forces (Sokhansanj and Crerar, 1999). The equipment consists of a grinder which produces and applies a consistent impact and shear to the pellets. This unit is relatively small, light and can be used on site. The amount of sample required for performing a typical test is 100 g and the testing time is reduced to 30 seconds. Hence, the running time and sample size for Dural are less than the Tumbler unit. Calculation for durability is similar to the calculation of durability with tumbler (Adapa, 2007)

ABSRACT - [ Total Page(s): 1 ]ABSTRACTDurability is used for quantifying the quality of briquette as the ratio of the unbroken weight to initial weight of briquette. This equally measure the durability of briquette under impact load during transportation and handling. A durability machine was developed and has dimension of 300mm×(25×25×3mm)×450mm.It was powered by electric motor of size 0.93hp.The results show that briquette formed from moringa stover has durability of 50%,63.4% and 79% from treatment T1 (100 ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1Â Â Â PreambleDurability is the assurance or probability that an equipment, machine or material will have a relative long continuous useful life, without requiring an inordinate degree of maintenance. It is the ability to undergo permanent deformation without cracking or fracturing. Â Durability testing is performance testing equipment used to determine the characteristics of a system under various load condition over time. This testing help us to identify the stabilit ...
