Products > Three Roll Mills > Three Roll Mill How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll …
The reduction of particle size is achieved by all three rollers running at varying speeds, creating a shearing action. Two side guides on top of the rollers aid the compounder in the placement of the compound onto the back set of rollers. The compound then moves through the mill …
The Three Roll Mills from EXAKT achieve an outstanding quality of dispersions in the development and production of adhesives and resins. More efficient properties of materials are achieved due to the controlled shearing, such as plastic or elastic deformability, electrical conductivity, resistance or strength, e.g. with CFK (Pre-Preg).

and an explanation of how these mills reduce ingredient particle size. Size Reduction The initial reduction of cereal grains begins by dis-rupting the outer protective layer of the seed (hull), ex-posing the interior (Figure 1). Continued size reduction increases both the number of particles and the amount of surface area per unit of volume.
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..

Sep 29, 2015· Jet milling (JM) was carried out using a Hosokawa Alpine 50AS spiral jet mill. The stress mode that effects size reduction in the air jet mill (Fig. 2b) is mainly impact, by way of particle–particle and particle–wall collisions.The collision energy is created by the high speed flow of compressed air (Neikov et al., 2009).Compressed air injection and grinding pressures of 6 bar and 4 bar ...
In addition, the roll faces can be grooved to further take advantage of the speed differential and improve size reduction. By placing (stacking) pairs of rolls on top of one another, two or three high, it is possible to reduce particle sizes down to 500 microns, duplicating the size-reducing capability of …
