Mathematical modelling of particle size characteristics and energy demand for mechanical size reduction of beech chips under different knife mill variables

Popis výsledku v původním jazyce

The effect of knife mill variables on comminute beech chips with 7.8 wt % in moisture was experimentally studied to define models that predict characteristic particle size and energy requirement based on knife mill variables. The experimental data showed that particle size decreases with the rotor’s increasing rotational peripheral speed and decreasing screen sieve size. Studying their mutual relations, an original empirical model was developed to predict particle size based on screen sieve size and rotor speed. The energy requirement of 1.47–12.62 kWh t-1 was reached to reach D50 particle sizes 0.48–1.58 mm. Regarding the brittle behaviour of beech chips, the Rittinger theory was applied to predict the energy requirement of size reduction with the Rittinger constant CRD50 = 13.0 kWh mm t-1 for D50 in size.
