Tiivistelmä
This bachelor’s thesis was commissioned by Valmet Technologies with the aim of studying the feasibility of building a mechanical condition monitoring system for high-consistency refiners. The thesis focused on how the system would be built using Valmet’s industrial internet applications. Ideas for potential business models and cost estimates for building a reliability monitoring system were included.
The theoretical framework of this thesis goes through principles of thermomechanical pulping and refining, with emphasis on high-consistency refining. The framework also covered the basics of Industrial Internet of Things systems, and how an intelligent condition monitoring system could benefit from these technologies.
Overall, building a mechanical conditioning monitoring system for high-consistency refiners is feasible. Technologically, the solutions available are excellent. The challenges lie in marketing the system. The refiner-as-a-service business model where customer pays for the runnability of their machine instead of the maintenance can solve this problem. It brings extra incentive to both parties to focus on keeping the equipment in top condition to achieve savings.
