Mining machine with dust collector apparatus
A continuous mining machine is propelled on a mobile body and includes a boom pivotally secured to the mobile body and extending forwardly therefrom. The boom rotatably supports a material dislodging device having cutting elements extending therefrom for dislodging material from a mine face. A longitudinal conveyor extends rearwardly on the body portion from a front end portion positioned rearwardly of the material dislodging device to a discharging end portion. A dust collector is carried by the boom in overlying relation with the conveyor front end portion. The dust collector includes a housing having a plurality of laterally spaced inlets for receiving pollutant laden air. A duct system connects the inlets to corresponding outlets where the air free of pollutants is discharged. A plurality of water spray manifolds are positioned in the housing at the inlets and direct a high pressure liquid spray to the outlets to induce an accelerated flow of pollutant laden air into the dust collector. The pollutant laden air is mixed with the liquid spray and flows through the duct system to the respective outlets. Each outlet includes a mist eliminator module for filtering the mixture of liquid and pollutants from the flow of air through the duct system. The air free of pollutants is discharged at an accelerated flow rate from the outlets and the liquid-pollutants slurry is drained from the mist eliminator module and directed onto the conveyor below the boom.
