Clean your dryer cans!
Fluoron's Beimfohr Roll Cleaning System (BCS) is helping many mills get their drying efficiencies and profiles back to where they should be.
Machines feel pressure
Fluoron's custom designed BCS machines have their own control system that can "feel" the amount of pressure required for each cleaning head to maximize the cleaning efficiency.
Cleaning is quick because of the multiple heads. Each head removes more of the build-up from the surface and the last head polishes it. The specially designed cleaning media range from coarse to very fine and do not remove significant amounts of metal from the shell. Where there is heavy deposit, a dust collector conveys the removed deposits to a filter bag. Heavy deposit is removed in the first pass and the next pass is for polishing finer media.
Fluoron says that the BCS cleans build-up from cans faster and less expensively than other methods, and without having a man in the machine. The mill needs only provide 60-psi air and 30-amp, 220/240- volt single-phase power with neutral line.
The BCS removes starch, size, coating and pitch as well as rust, hot melts and contaminants from recycled pulp. Fluoron says it is faster and more effective than blasting with sand, soda ash, dry ice or grinding.
If necessary, on large machines with heavy build-up, six heads can be used, progressing across the face of the dryer to clean and complete the resurfacing in one pass.
The BCS can also be used on felt rolls to prevent felts from losing their seams and to keep the felts straight. On troublesome felt rolls and stretch rolls, after cleaning Fluoron recommends the installation of Fluoro-Wear 102TM roll covers to eliminate corrosion and build-up which causes high felt wear.
A mill which had dryers on three of its paper machines cleaned in the past year reports,"The moisture profiles are a lot better and when you can run faster and have better quality, it pays for itself in a hurry. "
Once the cans are cleaned Fluoron has a variety of Release Coatings that will help keep your cans cleaner longer. Fluoron also produces Teflon Sleeves for rolls and dryers in FEP and High-Wear and Anti-static materials.
