06The production of biomass pellets is beneficial in several ways: In addition to improved storage and economical transport, pelleting particularly facilitates product dosing. Wood or long-fibre pellets are used, for example, as an alternative fuel or as an additive in compound feed production.AMANDUS KAHL has been manufacturing pellet mills since the mid-1920s and can look back on around 100 years of expertise in the design and manufacture of pellet mills for various industries. With the pellet mill 65 – 1500, the machine and plant manufacturer supplies the largest flat die pellet mill on the market, with a throughput capacity of up to 12 t / h in wood pellet production.The unique selling point lies in the flat die pellet mills, which are fed by gravity and press the product to be pelleted through a horizontal die. AMANDUS KAHL flat die pellet mills are characterised by sophisticated process engineering, centuries of knowledge and quality Made in Germany”. The machine repertoire for the biomass sector cur-rently includes more than 12 different pellet mill sizes, which are designed and manufactured to suit your project.
AMANDUS KAHL supplies the largest flat die pellet mill in wood pellet production with a throughput capacity of up to 12 t/h.

WOOD PELLETSFor thermal utilisation, environmentally friendly and for economic optimisation of your plant
Pelleted wood offers several possibilities of utilisation, one of which being that of a CO2- neutral fuel. Not only is large-scale industrial combustion becoming greener, but the number of pellet heating systems in private households is also increasing. When it comes to pelleting long-fibre products (40 to 100 mm), the process engineering advantage of AMANDUS KAHL also lies in the fact that there is no need for fine grinding: Uniform and energy-efficient grinding of wood is ensured by the pan grinder mill. With the KAHL flat die pellet mills, pellets are easily produced from softwoods, hardwoods and torrefied wood. With type 65 – 1500, a flat die pellet mill is available that is unrivalled in wood pellet production with a throughput rate of up to 12 t / h.
With the KAHL flat die pellet mills, pellets can be produced from softwoods, hardwoods
and torrefied wood.

Vegetable waste products are available world-wide, which in the past remained largely unused. These products are increasingly being recovered and passed on to further use. Pellets made from cellulosic plant products are ideal for compaction and for addition to feed mixtures. But thermal utilisation of straw pellets is also being favoured in an increasing number of large-scale industrial sectors. The successful flat die technology also makes pre-grinding of long-fibre products (40 to 100 mm) redundant.
LONG-FIBRE PELLETSCellulose-containing plant products —as a feed component or for thermal utilisation
The successful flat die tech-nology makes it possible to produce pellets from long- fibre products such as straw or grass cuttings.
Pellets from straw Straw bales as raw material Pellets from grass cuttings Pellets from hay

Depending on the field of application, different hardening processes are required, all of which are carried out in KAHL's own hardening shop for pan grinder roller and die production
� High robustness � Long service life and low wear � Low consumption of operating materials � Low lubricant requirement � Low operating costs � Fast and easy die change � Low space requirement and footprint � Low noise � Large pelleting chamber for products with low bulk density � Large pan grinder rollers with low circumferential speed � Adjustable pressure due to hydraulic system and thus easier machine start � Product feeding by gravity � Low maintenance - remote diagnosis possible
� Depending on the product, direct pelleting without fine grinding � Highest flexibility for pelleting raw materials � High pellet quality
� High vertical range of manufacture � Long-term service also after commissioning � 12 different pellet mill sizes for biomass pelleting � Product-specific design
