Ducon cyclones, Centrifugal Multivane Scrubbers, Dynamic UW-4 Scrubbers and Venturi scrubbers are used to control dust in driers and calciners and in crushing, screening and conveying areas in all kinds of non-metallic mineral mining, including limestone, clay, gypsum, trona, fluorspar, feldspar, pearlite, lithium, silica and refractories.

The success of Ducon equipment in lime kiln installations is evidenced by the fact that there has not been a single report on kiln shutdown due to scrubbers plugging.
