Process. 71 (2003) 147–166 149 To overcome these limitations, a new energy-based model for swing hammer mills was developed at the Julius Kruttschnitt Mineral Research Centre (JKMRC). This model consists of a crusher model with dual-classification function and a mechanistic power model to determine the dynamic internal recirculating load.

In the experimental research we used a grinding system controlled by a computer, equipped with a hammer mill (- 7.5). Energy consumption was determined using a module MAVOWAT 45. Along with measuring energy consumption the time and quantity of grinding was measured. The mill was equipped with three types of sieves (S1-4mm;S2 …

Under optimal working conditions of hammer mills, the energy consumption of milling pine wood to particle size of d 50 = 0.5 mm was 170 kWh·t –1 and for poplar 130 kWh·t –1 (Esteban and Carrasco 2006), therefore it was a reverse relation to the present results. This was due to almost twice the moisture contents of these …
