This plant, constructed in 2001/2002, and having a production capacity of 300,000 tonnes per year, had already been constructed in a highly energy-efficient way. A multi-stage grinding system using two-pass crushing mills and vertical-rotor hammer mills reduce the energy requirements by about 30% compared to a direct grinding system.

Hammermill - Wikipedia

The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size.

Comminution Properties of Biomass in Hammer Mill and its ...

Cadoche and López (1989) tested knife and hammer mills on hardwood chips, agricultural straw and corn stover. Energy consumption to reduce hardwood chips to a particle size of 1.6 mm was 130 kWh/Mg for both hammer and knife mills. The hammer mill required more energy (115 kWh/Mg) than a knife mill (50 kWh/Mg) for 3.2 mm particle size.

The energy content of wood pellets is approximately 4.7 – 5.2 MWh/tonne (~7450 BTU/lb), 14.4-20.3 MJ/kg.. High-efficiency wood pellet stoves and boilers have been developed in recent years, typically offering combustion efficiencies of over 85%. The newest generation of wood pellet boilers can work in condensing mode and therefore achieve 12% higher efficiency values.
