Both deep shaft and surface mining operations use a variety of DECENT MACHINERY fans. Non-sparking below-ground applications use both axial and centrifugal designs for ventilation and safety exhaust-and-supply systems. Quarry trucks and draglines require cooling fans for the large DC traction motors. Crushing and grinding phases of ore processing use many types of DECENT MACHINERY fans in environmental and ventilating systems. Some ore processing goes into a wet cycle where spray dryers and particle sizing systems direct products to chemical and food industries. DECENT MACHINERY offers fans for each of these applications.
