Pelleting
The pelletising system is designed for processing dry stalk materials of all kinds, such as cereal straw, rapeseed straw, hay, miscanthus or similar products. The system works completely independently.
All necessary production steps from bale breaking to grinding, conditioning, pelletising and packaging are integrated.
All installations are carried out from a single source. This means that the system is immediately ready for operation after an intensive briefing.
Stationary pelletising
Thanks to the modular design of the pelletising system, our specialists can develop the optimum solution for your needs. With a strong and constant hourly output, stationary pelletising is the best choice for customers who value continuous operation with low maintenance costs.
Mobile pelletising (On request)
The mobile pelletising plant can process largely unused agricultural by-products into pellets. The entire system is integrated into a lorry trailer and pelletises directly on site. This saves you high transport costs for the bales.
Stationary pelleting
- For short transport distances between the field and plant
- High flexibility in design and installation
- Extensibility of the system
Basic module consisting of:
- buffer tank
- conditioning
- mixer
- press
- cooling trough
- filter unit
- cabinet
Possible options
- Straw pelleting, with Straw and grinding system
- Bulk-pelleting with bulk adoption and grinding system
- Wood pelleting plants, with wood chippers for thin and thick wood
More options
- pellet cooler
- Steam generating unit
Round or square bales can be used as starting material. The bales are picked up and broken up by the bale breaker. A frequency-controlled screw conveyor feeds the pelletiser, pellet press with flat dies. The pellets produced are screened, cooled and conveyed further. The easy-to-operate machine controls are located on the control cabinet;
Hourly output
The hourly output was calculated at up to 1.2 tonnes/h for the entire system. The output depends on the material type and quality, the die and the degree of grinding. The calculation is based on the processing of dry, homogeneous wheat straw (residual moisture < 14%). Fluctuating qualities of the raw material to be processed can significantly influence the hourly output. A die configuration suitable for the material is necessary for processing with optimum performance.
Energy consumption
The installed power is 180kW. Of this, approx. 130kWh is consumed during operation. Depending on the type of material and settings.
The aforementioned systems are designed for single-shift operation up to 250 days a year, in compliance with maintenance regulations. Continuous system operation by at least one operator is required.
Dimensions
The space requirement is 120m², with a height of 5.50m. The system can also be installed in a more compact form. Each system is assembled on site according to your requirements.
