Three Roll Mill
Details of Three Roll Mill
- Two types: handwheel and digital control gap
- Safe scraper socket, Emergency-stop
- Space-saving desktop models
- Drip tray for easy cleaning
Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic
The three roll mill is equipped with an emergency stop button to prevent foreign objects from entering the machine body, thereby damaging the equipment. Users can also choose the appropriate roller shaft material according to their own needs. Generally, the roller shaft is made of special hard alloy or ceramic materials, and granite is also used for special applications.
Working principle of a laboratory three roll mill
The laboratory three roll mill consists of three rollers mounted on a frame and driven directly by an electric motor. Generally, the rotation directions of the rollers of the three roll mill are different from each other, the front roller rotates forward, and the middle roller rotates backward. The speed of the front roller is fast, and the speed of the rear roller is slow. We often define the roller axis by fast, medium, and slow rollers. The intermediate roller shaft is fixed on the machine body, and the fast and slow roller shafts are installed on the slideway. The body of the three roll mill is equipped with a spring device, and the distance between the fast and slow rollers and the middle roller is adjusted by a hand wheel or controlled by PLC. The material is squeezed into the surface between the fast roller and the middle roller so that the particles are refined, and finally, flow out through the discharge port. A scraper is installed at the end of the three roller mill to separate the material from the body and drop it. into the collection bucket.
The machine realizes the grinding function by squeezing and rolling the surfaces of the three rollers arranged in the horizontal direction of the machine, and rubbing at different speeds. Grinding materials generally only need to be ground twice to meet the requirements, and materials that are difficult to grind must be ground many times to meet the requirements. The processing fineness of the three roll mill can generally reach about 1-20 microns, which can meet the needs of many industries.
The use of a laboratory three roll mill
The laboratory three roll mill is mainly used for various pasty materials, such as paint, ink, plastic, pigment, food, etc. It is especially suitable for grinding and dispersing products with high viscosity and fine particle size. The role is centrifugally cast with chilled alloy cast iron, with a dense crystal phase, high strength, high surface hardness, good wear resistance, and a cooling system.
1. Suitable for high-viscosity materials.
2. It is suitable for the dispersion of difficult-to-disperse pigment coatings.
3. Easy to clean and change colors, suitable for small batches and production or development of various products.
4. The quality of grinding and dispersion is high, which can reach a higher fineness, to give full play to the coloring power and hiding power of the pigment, and save the consumption of pigment.
5. The rollers are made of alloy, and you can also choose zirconia.

Guidelines For Three Roll Mill
Three roll mills are widely used in a variety of chemical industries, from medium to high viscosity productions. FRANLI machine can break open all kinds of pigment, UV ink, offset ink, decorative paints, and Lubricants, it also can catch the greatest fineness in cosmetics/ lipstick and electronics industries.
Three roll mill is the main equipment for grinding colored carbon black, as it is used extensively in rubber, plastics, paints, and inks, and some carbon black is added.
The laboratory three roll mill is equipped with the most advanced PLC functions to continuously improve the operability of the most primitive production equipment.
The three roll mill plays a vital role in the grinding of grease. Grease is essentially a kind of lubricating oil, which is a solid or semi-solid product formed by one or more thickeners through the grinding and dispersing action of a three roll mill.
Three roll mill is the main equipment for grinding attapulgite. The attapulgite is ground and dispersed mainly because it is a natural colloid. Even if the size of the attapulgite reaches 0.1mm, it cannot be easily dispersed by the machine, so the final state of attapulgite formation has been greatly developed.
The three-roll mill is mainly used for grinding materials of various viscosities and is one of the best wet grinding equipment. The dispersing and emulsification effect of the three-roll mill is excellent, especially for ink, paint, colloid, chocolate, plastic, cosmetics, etc., whether it is liquid slurry or paste material, the three-roll mill can work easily.
The 3 roll mill is a grinding and dispersing equipment, which plays an irreplaceable role in improving the quality of coating products.
