Modular Design Options
Flat die pelleting press Heavy duty pelleting press, best performance in biomass
Discovered by many users in recent years
Flat die pelleting press
The Flat Die Pelleting Press - Since decades the pelleting press for fibrous materials - Strongest machine and bearing design for wood - Large press chamber – no space limitations for tools - Extreme low running costs - Highest efficiency and production safety
The Kahl Flat Die Pelleting Press - Heavy Duty design for best performance - up to 8 t/h capacity - up to 500 kW drive motor power - Longest life time for dies, rollers and roller bearings, up to 2000 – 4000 hours
- Lowest grease consumption for roller bearings due to low roller speed - Proven results in all kinds of biomass pelleting as wood, sugar beet pulp, straw, oil palm waste, bagasse
