An alternative to the walkway-side fan sprays would be to mount sprays on the underside of the splitter arm. Once again, high-capacity fan sprays could be positioned evenly along the length of the splitter arm and aimed down toward the conveyor. These sprays may have a positive effect on reducing the dust rolling under or through the splitter arm belting and should add more water to the coal product on the pan line, thus reducing conveyor dust. Achieving the desired results by locating sprays on the underside of the splitter bar may be challenging given the amount of turbulence in that area. Spray pressure becomes critical, and low spray pressure may not be effective in reducing the dust migrating under the belt, while too high of a spray pressure may create more turbulence at the bottom of the belting and induce more dust to migrate into the walkway.
