Increased competition in the capital-intensive paper industry makes optimized operation to an important part of corporate strategies to reduce them overall costs. Running the machines in a reliable way contributes to higher plant availability, which is particularly important in industries where the production rate is high and a break lead to costly production downtime. To achieve high plant availability, an effective maintenance of manufacturing equipment is required. This requires that the right action is taken at the right time. The purpose of this project was to increase understanding of how operation parameters for a paper machine affect the condition of the machine. The condition is assessed by studying the vibration levels using a con...
