classification of roll mill ppt

CLASSIFICATION OF CONSTRUCTION EQUIPMENTS

The classification could be on the basis of the function an equipment performs-for example, materialloading function, material-transporting function, etc. In the functional classification, equipments are grouped into (a) power units, (b) prime movers, which make it possible for the equipment to operate, (c) tractors, (d) material-handling equipment and (e) material-processing equipment.
