ANDRITZ belt dryer for biomass: Biomass drying, necessary pretreatment for further processes

ANDRITZ supplies the complete process, not only for sludge treatment, but also for biomass drying - from wet milling to drying, fine milling and pelleting, all from a single source.
In most cases, biomass (wood bark, woodchips, sawdust, and energy chips) have to be dried before being used in pelleting, briquetting, incineration, and gasification. By reducing the biomass water content to 10-15%, its calorific value is increased from 2 kWh/kg to approximately 4.5 kWh/kg.
This cuts the transport and storage costs, as well as creating ideal conditions for direct firing or optimum pelletizing properties, both for industrial and high-grade wood pellets. As a result of the drying process, less fuel input is required to generate energy, which also reduces the pollutant emissions caused by the combustion system.
At ANDRITZ, you benefit from wide reuse possibilities for best sustainability thanks to our large range of thermal systems (paddle dryer, belt dryer, fluid bed dryer, and drum dryer).
