the Bond Work Index (BWI) for tube and ball mills [9,10]. No stan-dard grindability tests currently exist for biomass, and there have only been limited studies on the use of standard grindability tests for coal on biomass, which have mainly focused on torrefied mate-rials [11–16]. This paper aims to analyse the applicability of the

For the simplified Bond method, an approximate work index may be determined by running a batch dry-grinding test. The test was performed using a 25 cm diameter tumbling ball mill with material hold-up of about 10%, media loading of about 25% and a unit interstitial filling. Two kilograms of the 5 mm lignite samples were ball
