Preparation of graphene by exfoliation of

Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium Multi layered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N N dimethylformamide DMF and exfoliated by shear force dominated ball milling carried out in a planetary mill After high speed centrifugation irregular shaped single and few layer graphene sheets ≤3 layers

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore The balls are initially 5 10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol % ore and 25% steel The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones
