Witte designs sludge handling equipment to dewater and dry to tight moisture specifications with particle integrity assured.
This sludge system combines a vibrating dewaterer with a vibrating fluid bed dryer that are both easy to access and clean to overcome the problems a round fluid bed dryer was causing.
Case Study:
NEW FLUID BED DRYER INCREASES PRODUCTION BY 50% WHILE SAVING $60,000.00 PER YEAR IN MAINTENANCE

No one could determine precisely why the mysterious goo was forming on their dryer but the operators at Complete Spill Solutions, Watertown, New York, had had enough of trying to remove the sticky sap-like goo that was blinding its screens and CEO Geoff Perry was growing increasingly concerned about its impact on productivity. Drying up to 75% moisture recovered fibers from the waste stream of a paper mill, Mr. Perry had targeted production rates of 2,000 lbs./hr. but the design of the round fluid bed dryer hampered his efforts.
“This ‘goo’ was a horrendous problem,” says Mr. Perry. “We had to shut down the entire line once per month to clean the dryer, which was a major undertaking. In labor costs and lost production alone, this cost about $5,000.00 every month.” The dryer’s sintered screen design was prone to warping that created peaks, valleys and dead spaces where the gooey residue would form, gather and clog. This blinding prevented efficient airflow and caused severe drops in productivity. “It would get progressively worse until the product came out wet and we had no choice but to shut down,” adds Mr. Perry
