Drop shatter test

WebSummary of Method 6.1 A test sample is prepared by removing and discarding the coke smaller than 50 mm (2 in.) from a representative gross sample. The test sample, approximately 23 to 25 kg (50 to 55 lbs) is dropped four times from a height of 1.83 m (6 ft) onto a rigid steel plate. The shattered coke is sieved. Webbriquette was measured using drop shatter test. Experiment results show that briquetting pressure of 500 bar could be utilized to evaluate the lignin characteristic in briquetting process. Highest performance of lignin as internal binder in briquetting was obtained at temperature 164 ℃. In this temperature, briquette with DSI as high as 83% ...
