Compléter Review of conceptsVersion en ligne Review of the main concepts par Iris Usach Pérez 1 vibration high nonionic anionic W flocculated deflocculated nonionic deflocculated reduce flocculated elastic W increase plastic O ball O In materials there is an elastic limit . Span is a emulsifier that forms / emulsions . The best equipment to pulverize abrasive materials is the mill . In suspensions , the rate of sedimentation is high . High hardness materials the lifetime of mills . Brittle solids are examples of materials . In the mill , cylinder is filled up to 80 % of its volume with balls . The volume of sediment in suspensions is higher than in ones . Tween is a emulsifier with HLB . Moisture values higher than 5 % the adhesiveness of particles . Soaps are examples of surfactants that give / emulsions . The re - dispersion of sediment is more difficult in suspensions .
