Valmet Mining Introduces RFID-Enabled Filter Cloths
- Nov 28, 2016 -

Finnish technologies company Valmet Technologies is launching a radio frequency identification system to track the use and replacement of cloth filters for its customers, including mining, paper and energy companies. The solution, which includes tags attached to filter cloths and readers mounted on a framework that holds the filters, tracks when each filter is installed, when it was replaced and why this was necessary. In this way, the technology provides analytics that help customers monitor the replacement of cloth filters, enabling them to better schedule future filter changes. The system will also help Valmet improve its products, by allowing it to view how well they perform in specific environments and under certain conditions.
Valmet makes a wide variety of textile-based filters for various industries. The filters are designed to separate solids from liquids or gasses. Organizations such as mining firms, paper producers and energy companies use such filters to remove solids for numerous purposes. Over time, the cloth can become clogged (a process also known as "blinded") or break, requiring that it be replaced by a new, clean filter. These cloths, provided by Valmet, vary in size from 50 square centimeters (7.5 square inches) to large pieces that can measure as much as 100 meters (328 feet) in length and require a crane for installation or removal.
