This is cleaning of a 67" poly-backed belt at an MDF plant on a 4-head Kimwood sander, using our patented dry ice cleaning system, which is automated. They are producing an MDF Board, using 50% hardwood/50% softwood. They clean every 4 hours with the push of a button. Each cleaning takes about 1 minute. The cost of the dry ice is about $1.50 for each cleaning.
They have extended their belt life up to three times, getting three belt lives instead of one, saving 67% of their previous expenditures on abrasive belts. If you do the math, they get an ROI 2.55 times per year. Along with that, they have improved their sanding quality, reduced the number of belt changes, and have reduced their landfill waste from belts by 67%.
This system has been operating trouble-free since 2021.
