In the vibratory ballmill, compression and attrition are created by the milling media (ball and cylpebs) which are maintained in motion by the vibration of the tank . It is more or less equivalent of traditional ballmill but it is particularly adapted to lignocellulosic biomass by maximizing attrition. In a jetmill.

 · An effective mechanical activation (MA) + metal salt (MAMS) technology was applied to pretreat sugarcane bagasse (SCB), a typical kind of lignocellulosic biomass, in a stirring ball mill. Chlorides and nitrates of Al and Fe showed better synergistic effect with MA, especially AlCl 3, ascribing to the interaction between metal salt and oxygencontaining groups induced by MA.

All dried solid biomass was milled to finer particle size using the Retsch PM 100 Ball Mill and sieved before taken for fuel characterization and combustion characteristics experiments. Any sample that did not pass through the sieves underwent the milling process again. Thus, all materials were milled to <180 µm. Blends were produced from both untreated and washed fuels with 90 wt% pine and ...
