Durability 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 (100g ) , T2 ( 200g ) And T3(300g) respectively with corresponding unit density of (0.126kg/m3,0.130kg/m3 and 0.194kg/m3).Castor stover has durability of 63.4%,73.3% and79,7% from treatment T1 ( 100g ) , T2 (200g ) And T3(300g) respectively and unit density of 0.162kg/m3,0.167kg/m3and 0.193kg/m3).sorghum stover has durability of (73.3%,79% and 87.4%) from treatment T1(100g), T2(200g) And T3(300g) and unit density of 0.316kg/m3,0.273kg/m3and 0.262kg/m3.the testing duration 3min and rotational speed 40rpm. . The durability test shows that sorghum stover has the highest durability compares to moringa stover and castor stover.
