In the present study, a three-roll mill machine was used to disperse/exfoliate the nanoclay particles in an epoxy matrix. The compounding process was carried out with varying mixing time and concentrations of clay particles (1 to 10 wt.%). It was found that the longer the mixing time, the higher the degree of intercalation.

— In the approach of Gojny et al. [6], [24], [25], [26] nanotubes were mixed into epoxy resin and then small quantities of the mixture added batch-wise to a three roll calendering mill with a gap setting of 5 μm between the rolls. The small gap between and mismatch in roll velocity results in enormous shear forces.

A three roll mill is composed of three horizontally positioned rolls rotating in opposite directions and at different speeds. The material to be milled is placed between the feed and center rolls and gets transferred from the center roll to the apron roll by adhesion. The shear forces between adjacent rolls generate the dispersion.
