A mining machine of the type comprising a body, a driven cutter mounted on the body, and an air-cleaning system comprising ducting for conducting dust-laden air, a scrubber for applying liquid to the dust-laden air, and a demister for thereafter removing moisture from the air. The demister comprises a moisture separating station having a flow inlet, a flow outlet located rearwardly of the flow inlet, and moisture separating louvers arranged for receiving air flow from the inlet and causing moisture in the air flow to separate-out and gravitate toward a lower collecting surface to be conducted rearwardly. The inlet and outlet each include a lower level. The distance from the collecting surface to the lower level of the inlet is less than the distance from the collecting surface to the lower level of the outlet to minimize the re-entrainment of the rearwardly conducted moisture into the outgoing air flow. A moisture discharge is located adjacent a rearward end of the collecting surface to remove the rearwardly conducted moisture. The discharge comprises an accumulating section located at a rearward end of the collecting surface and includes a forwardly facing entrance. The lower ends of the louvers extend substantially to the collecting surface to minimize by-passing of the louvers by the air flow. |
