A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
The EXAKT 50 ensures the finest results and ultimate particle size reduction in topical, oral and suppository applications among is impressively underlined by the fact that the EXAKT 50 is used in more than 30,000 pharmacies worldwide. Especially in the preparation of ointments and creams containing powdered or crystallized ingredients, the EXAKT 50 proves superior to even highly ...
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 sizereducing capability of .

Dec 11, 2013· Three Roll Mill 101 An introduction to a high shear blending and dispersion tool. ... For chocolate products, the final fineness is around 2030 microns. For particle size reduction, on the other hand, Torrey Hills planetary ball mills create extremely strong impact force to break apart the existing chucks/small particles. ... The resultant ...
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 at 270 rpm.
and an explanation of how these mills reduce ingredient particle size. Size Reduction The initial reduction of cereal grains begins by disrupting the outer protective layer of the seed (hull), exposing the interior (Figure 1). Continued size reduction increases both the number of particles and the amount of surface area per unit of volume.
The screen is used to control the size of the particles exiting the mill. Various screen types and hole sizes are used to change the final product particle size. Hammer mill configuration. The three basic types of hammer designs are: The stirrup or LFS hammer, the swing bar .

A comparative study conducted at the University of Hamburg, Institute of Pharmacy in Hamburg Germany concluded that the quality of compounds processed with three roll mills is better than those processed with electric mixing systems. Particle size is smaller. Particle size distribution is narrow. Ointment stability is better.
How the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.
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.
