A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.. The three-roll mill has proven to be the most successful of the range of roll mills which saw extensive development in ...
in the epoxy resin, known as three-roll mill. As shown in Figure 1, the three-roll mill consists of three rollers between which the resin mixture passes through as the rollers rotate in the directions shown. The equipment is set up such that the rotational speeds of the rollers are in a ratio of 1:3:9.
It consists of dispersing freeze-dried GO in a DGEBA epoxy resin using a three-roll mill and subsequently curing at a relatively high temperature with an anhydride curing agent, thereby both partially reducing the GO to rGO in-situ and curing the epoxy matrix. The …

In order to obtain a high quality of dispersion of the respective filler material in the viscous epoxy resin, the dispersions were produced on a three-roll mill (TRM) from Exakt (80E) with SiC-coated rollers. The gap size was precisely controlled starting from 120 µm in the very first step, down to <5 µm in the final processing steps.
Furthermore the homogenous dispersion was processed at a three roll mill (120 EH-250 of EXAKT) in several passages. The roll mill consists of two roller gaps which can be operated with a defined roller gap or a defined force that presses the rolls together.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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 ...
The batch was three-roll milled for several times on a laboratory scale three-roll mill (EXAKT 80E, EXAKT Technologies Inc.) at different shear intensities. Next, the mixture was degassed in a vacuum oven at 90 °C for 30 min and loaded between two aluminum plates coated with demolding agent and separated by a PTFE spacer of 1.6 mm thickness.

Electrical and thermal conductivity of composites which contain carbon-based fillers in an epoxy matrix were investigated. The fillers were dispersed in the liquid matrix by using three roll mill equipment. The filler/matrix mixture was cast in a mold and then cured, thus obtaining composite specimens. Multiwall carbon nanotubes, graphene-like nanoplatelets, and graphite were used as fillers ...
Quaker Color specializes in the manufacture of solid pigmented dispersions (SPDs), also known as "Chips.". Our solid pigmented dispersions are produced in a 2-roll mill process and provide outstanding color performance. The SPDs come in multiples resin systems, including Epoxy (3 …
Tools to achieve dispersion include three roll mills, ball mills and bead mills for the final dispersion. Three roll mills are most commonly in the production of screen printing, pad printing, UV, and glass/ceramic inks, since they are more viscous in nature. For liquid inks, other types of mills should be used since the solvent would evaporate ...
