How the MP700 came about – heavy-duty pellet mill for demanding raw materials
The MP700 was born out of an extraordinary challenge: an industrial operator needed a pellet press that could handle extremely fibrous and difficult to press raw materials. Conventional presses regularly reached their limits. The result was insufficient throughput, unstable processes and a high susceptibility to faults. The press channel and rotor in particular were unable to cope with the loads.
Initial situation and problem definition
The customer was working with a raw material whose properties differed greatly from traditional sawdust or mixed biomass. The fiber length, the resilience and the low flowability made the process particularly challenging. Standard rotors tended to clog, block or produce an irregular material flow. The existing machine technology was not designed for these raw material characteristics.
The turning point: development of a special rotor
The solution was to develop a completely new rotor that took the special properties of the material into account.
The objectives were clearly defined:
Stable feeding despite fiber-rich structures
Controlled compaction in the press channel
Uniform material transport without accumulation
Robust geometry for high mechanical loads
The customized special rotor was designed specifically for this application and iterated several times until the geometry, angle of inclination and pocket volumes were perfectly matched.
Machine development based on real process data
The MP700 is not a product of chance, but the result of close interaction between:
real material tests
practical operating experience
Direct feedback from production
constructive further development based on real weak points of conventional presses
The result is a machine that optimally takes into account both the material behavior and the process mechanical requirements.
The effect in practice
The system reached the special rotor:
Significantly higher process stability
continuous material flow
Reduced energy requirement due to uniform compaction
Less downtime and less tendency to clog
Higher production output with the same engine power
The MP700 can handle raw materials that can hardly or not at all be pressed economically with standard presses.
Result
The MP700 is a heavy-duty pellet press for the most demanding applications.
It shows how individual design and targeted further development can turn a problematic process into a stable, efficient solution. The special rotor is at the heart of this development and makes the machine unique in its performance class.
