Modelling of particle size characteristics and specific energy demand for mechanical size reduction of wheat straw by knife mill

Popis výsledku v původním jazyce

Mechanical size reduction, due to its significant effect on transport phenomena and biodegradability, is the crucial initial step in the production of advanced biofuels. As is generally known, particle size reduction is high energy demand operation. Energy requirements were experimentally studied and mathematically modelled for the processing of wheat straw with 4.6% moisture content wet basis that was reduced in size using a knife mill. The characteristic particle sizes for wheat straw before and after milling were analysed using the Rosin-Rammler-Sperling-Bennet model of particle size distribution. Energy demand 0.7–21.2 kWh t-1 was reported for size reduction of wheat straw with size reduction ratio D50 equal to 1.13–3.86. Applying the theory of energy demand modelled by Rittinger, it was confirmed that treated wheat straw displayed brittle behaviour. Energy demand for size reduction of wheat straw can be therefore be estimated using Rittinger theory with Rittinger constant value of 9.9 kWh mm t-1.
