Advantages of Three Roll Mill

User-friendly:

Three roll mills are thoroughly advantageous for their ability to mill the pastes with high viscosity. Interestingly, its superior surface contact having a cooled roller makes it possible the keeping the temperature low, even if dispersion work of a greater amount is put in. The higher surface area is also one of the prime reasons behind the user-friendly characteristic of these mills.

Flexibility:

Interesting aspect about the three roll mill is that here one can adjust and also maintain the gaps in between the rolls in a mechanical way. In general, the size of the gap is way bigger than that of the size of the particle. In certain cases, the distance of the gap is strategically minimized in order to attain a specific level of dispersion. Generally, the rollers remain water-cooled internally.

High utility:

The three roll mills are frequently used in chemical industries of different levels, ranging from those with medium level viscosity production to that of high level. Using high-end machinery, one can break down a whole range of pigments, inks, paints, as well as lubricants.

Provides greater flexibility as per production volume:

Best part about the three roll mill is that there remains flexibility to select the right kind of model in accordance with the volume of production. For example, the small bench types are meant for works related to development of bench-top, laboratory works, as well as for production of low volume. Similarly, the large bench models, as well as the floor models, are made for meeting well with various kinds of production demands, ranging from pilot plants to produce in large volumes.

Our Best-Selling Three Roll Mill

Hydraulic Three Roll Grinding Mill
TRANSOCEAN® hydraulic three roll grinding mill has three horizontal rollers i.e. feed roll, center roll and apron roll. Each roller rotates in an opposite direction from the adjacent roller with a tiny gap between them adjustable by the hydraulic system, which generates tremendous shear force to the materials to process.

Coating Three Roller Grinding Mill
TRANSOCEAN® coating three roller grinding mill is widely used to mix, disperse, grind and homogenize viscous pastes to produce qualified coatings. It consists of three horizontal rolls, namely feed roll, center roll and apron roll. Each roller rotates in an opposite direction from the adjacent roller with a tiny gap between them.

Triple Roller Grinder
TRANSOCEAN® triple roller grinder is composed of three horizontal rollers, namely feed roll, center roll and apron roll. Each two adjacent rollers rotate in opposite directions. Feed roll and center roll rotate towards each other, while center roll and apron roll rotate back to back.

Key Components of Three Roll Mill

A three-roll mill consists of three rotating rollers, usually made of stainless steel or other durable materials. The rollers are arranged horizontally, with each roller rotating at a different speed to apply shearing forces to the material. This design helps break down larger particles, mix components more effectively, and produce a fine, smooth final product.
Roller 1 Rotates at a higher speed, pulling the material into the gap between the first and second rollers.
Roller 2 Moves at a slower speed, allowing the material to be refined further as it is squeezed and sheared.
Roller 3 Rotates at the slowest speed, refining the mixture even more before it exits the mill.

Basic Principles of Three Roll Mill

Shear forces between the adjacent rolls break up the agglomerates in the product. When the apron roll is engaged, the material transfers to it while being subjected to additional shear forces at even higher intensities. The distance between each roll is adjustable and impacts both shear level and throughput. Gap size is typically set at 0.005" and as tight as 0.001" in some cases. Milled material is scraped from the apron roll by a take-off knife. The cycle can be repeated to improve dispersion quality or until an equilibrium particle size distribution is reached.

Applications of Three Roll Mill

Ink Manufacturing
One of the most common uses of a three-roll mill is in the printing ink industry. These mills are ideal for breaking down pigments and dispersing them evenly in the ink, ensuring that the final product has a consistent color and quality. The ability to control the viscosity of the ink and achieve a smooth, homogeneous mixture is crucial in the production of high-quality inks for printing.

Coating and Paint Production
In the paint and coating industry, a three-roll mill is used to create smooth, uniform coatings for various applications. The mill helps to blend pigments, fillers, and other additives into a stable, consistent paste that can be easily applied to surfaces. The process also ensures that the pigment particles are well-dispersed, preventing clumping or uneven coloring.

Cosmetics and Personal Care Products
The cosmetics industry benefits significantly from the use of three-roll mills for the production of products such as creams, lotions, lipsticks, and cosmetic gels. These products require precise blending and uniformity, which the three-roll mill provides by reducing particle size and improving dispersion. This ensures that products have smooth textures and enhanced skin compatibility.

Pharmaceuticals and Drug Formulations
In the pharmaceutical industry, three-roll mills are used to produce high-quality creams, ointments, gels, and drug formulations. The mills help to reduce the particle size of the active ingredients and ensure a uniform dispersion in the final formulation. This is particularly important in the production of topical drugs, where the consistency of the product can impact its effectiveness.

Adhesives and Sealants
The adhesive and sealant industries use three-roll mills to achieve optimal consistency and dispersion of resins, fillers, and other components in adhesive formulations. The uniformity achieved by these mills ensures that the final adhesive or sealant has the required strength, adhesion, and curing properties.

Food Industry
In the food industry, three-roll mills can be used to process a variety of ingredients, such as chocolate, sauces, and spreads. These mills can help to achieve a smooth texture and prevent any unwanted clumps in food products.

Lubricants and Greases
The production of lubricants and greases often requires the dispersion of additives in high-viscosity base oils. Three-roll mills are ideal for this purpose, as they can handle heavy oils and grease formulations with ease. The mill ensures that the thick lubricants are uniformly blended and free of any large particles or air bubbles that could affect performance.

Ceramics and Inkjet Printing
In the ceramics and inkjet printing industries, three-roll mills are used to create fine dispersions of inks and pigments. These industries require extremely smooth and consistent coatings for ceramic tiles, printer inks, and colorant applications. The mills help to reduce particle sizes, ensuring that the inks and pigments are evenly distributed and provide the desired color intensity.
