Filter cleaning machine could dust thousands off maintenance bill

The movement of ore, either through surface or underground operations, generates a tremendous amount of dust. The tiny dust particles must be run through filters to avoid damaging, or impeding the performance, of moving parts located in key pieces of mining equipment, including trucks, loaders, shovels, and crushing and grinding machinery.

Canadian company Diversi-Tech saw the opportunity in the problem, and the result was the “Green Machine.” The machine releases compressed air through a rotating air jet that moves up and down in a spiral motion inside an enclosed chamber. As the filter is cleaned, pollutants are captured and stored in a 55-gallon drum.
