Valmet iRoll technology improves production efficiency and product quality by assuring optimal runnability of pulp drying machines. A pulp producer can obtain significant cost savings by improved press nip profiles for better dewatering, avoid web breaks by better tension control or reach more efficient air drying by optimal parameters.
iRoll may be utilized on a covered roll in the pulp drying line to expand the roll’s primary function to include the use as a transducer for sensing cross-machine nip linear load or sheet properties such as tension and hardness profiles at reel or winder (with reeled pulp). iRoll Temperature profile measurement system can be utilized to monitor roll covers or sheet profiles for optimizing the drying processes.
iRoll can be connected to automation and data collection systems. It also has advanced tools for data analysis, drawing color maps and more. With up to 200 data points in the cross-machine direction, iRoll provides high resolution profile feedback. Data from iRoll is truly online as it is updated by up to 10 profiles per second.
iRoll Press enables online nip profile measurement in press nips to assure optimal dewatering in the nip.
iRoll Tension online tension measurement of pulp web for reducing sheet breaks.
iRoll Temperature measures temperature CD profiles and MD trends online inside the roll cover to optimize air drying – enabling energy savings and excellent runnability.
iRoll Reel provides parent roll hardness profile and online control.
iRoll Winder monitors the end product quality and reveals winding issues such as discontinuities in the nip loading.
Monitoring based on iRoll nip profiles, vibrations and optimization data are some examples where roll condition information is analyzed. This provides security for our customers that technical solutions and recommended upgrades are based on their actual needs and goals.
Valmet's remote support and analysis services connect pulpmakers to Valmet experts online, if they are using iRoll, roll condition monitoring or other Intelligent Roll Solutions.
