With this system, dust can be suppressed before it becomes airborne. A series of nozzles discharge a chemical compound in a fine spray to materially reduce the amount of water or other liquids necessary to saturate fly ash and eliminate dust. The compound also aids in the diffusion of the liquid dust suppressant, allowing it to penetrate deeper into the material. This system can be used at any point in the handling of bulk materials, wherever dust is a hazard.
Industry:Mining
Wood bars or steel rails fixed vertically to cross buntons in a shaft. The cage shoes travel along the guides and therefore prevent the cage from swinging and doing damage in the shaft. Some skips are fitted with rubber-tired rollers running on 6-in by 4-in (15-cm by 10-cm) steel channel guides. Guide shoes may be fitted to act as alternative guides in 1214 case of breakdown of rollers. Fixed guides are used when shaft space is limited; i.e., when the clearances do not permit the use of flexible or rope guides.
