Conveyors. Coal, iron ore, and concrete are just some of the materials that conveyor operators must move efficiently. For this, they require robust conveyor systems that work effectively and reliably, and resist failure under challenging conditions. SKF expertise in rotating machinery and components, such as bearings, that underpin it, can.Fresh Concrete In general, supplementary cementitious materials improve the consistency and workability of fresh concrete because an additional volume of fines is added to the mixture. Concrete with silica fume is typically used at low water contents with high range water reducing admixtures and these mixtures tend to be cohesive and stickier.
