In the world of biogas plants, high demands are placed on agitators. Wear tests are crucial for selecting the right material. Particularly interesting are the differences between stainless steel and Physinit.
The importance of wear testing
Wear testing is essential to determine the durability and efficiency of materials. Stainless steel propellers often face problems such as tangling, abrasion and imbalance. PTM’s Physinit, on the other hand, has proven to be more resistant to these problems.
Physinit material properties
Physinit offers many advantages: it is homogeneous and stress-free, seven times lighter than steel, chemically resistant and extremely abrasion-resistant. It is also dimensionally and shape-stable and hydraulically optimised, which enables significant energy savings.
Wear test details
On a full laboratory test bench, stainless steel and Physinit propellers were tested under identical conditions. Mass loss, diameter and wear rate were measured over seven days.
Experiencia practica
Many biogas plant operators report significant improvements with Physinit propellers, especially in plants with a high chicken manure content. While stainless steel propellers often wear out, Physinit propellers remain virtually intact, significantly reducing operating costs.
Why PTM uses Physinit
PTM recognized that Physinit is the ideal material for this application. It is used not only for propellers, but also for damping elements that prevent tension on the lifting cables, preventing them from breaking.
Looking Ahead
PTM continues to innovate, collaborating with industry partners and institutions to further improve the efficiency and reliability of biogas agitators. Physinit remains a core component of its technology.
Experiments with Physinit have been intensified. The material shows even greater potential for a wide range of applications. New projects and additional application areas are also being explored.
Conclusion
Physinit propellers have proven to be the best choice for biogas agitators. The combination of low wear and high efficiency with this innovative material sets new standards in the industry.
