In the present thesis, the dependence of wood pellet degradation and fines formation during pneumatic conveying on operating conditions like air and product mass flow or shape of pipe components is investigated. Both the size reduction of the cylindrical pellets during pneumatic transport caused by mechanical impacts and the prevailing pressure losses are analysed experimentally and numerically. Single particle impact tests are performed for investigating the breakage behaviour of wood pellets including the effect of particle length, impact velocity and collision angle. Based on the empirical ...
