Hammer mills prepare woody biomass for the pelleting process. It is vital to pay close attention to the hammer, as it has an important influence on performance. Hammer mills turn heterogeneous material into homogeneous material. Grinding with hammer mills is done in feed mills, food processing, plastic waste and biomass operations.

Our paper presents the hammer mill working process optimization problem destined for milling energetic biomass (MiscanthusGiganteus and Salix Viminalis). For the study, functional and constructive parameters of the hammer mill were taken into consideration in order to reduce the specific energy consumption. The energy consumption dependency on the mill rotor spinning frequency and on the sieve ...

Reducing biomass particle size results in densification which in turn improves the handling, packing, transportation and biodegradability [7]. Traditionally, grinding of biomass is enabled by specialized mills such as knife mill, hammer mill, ball mill, attrition mill or shredder [6, 8]. Each type of preprocessing tools has certain advantages ...

The hammer mill screens with mesh diameter openings of mm, mm, and mm were used, resulting in six different batch samples—three samples for each of the poplar wholetree fractions. The drying of the biomass to about 4% moisture content prior to milling was necessary in order to avoid clogging the hammer mill screens during grinding.
