The speed and fineness of the rollers of the three roll mill can be controlled manually or through the PLC interface. Each three roll mill is equipped with a safety device, which has the characteristics of high reliability. There are many kinds of roller materials. Common rollers are cast from alloy steel. This material has high strength, high hardness, and good wear resistance. Users can also choose ceramic rollers, marble materials, etc. according to their own materials. Rollers The hollow method can be used to realize the cooling water to reduce the temperature of the material during grinding and ensure the quality of the material.
The three roll mill achieves the final grinding state through the mutual extrusion and friction of the three rollers arranged in the horizontal direction of the machine and friction at different speeds. The user can choose a feeding machine or a hopper to automatically load and grind the material. Generally, the grinding material only needs to be ground. The requirements can be met twice, and the difficult-to-grind materials must be ground many times to meet the product requirements. The final processing fineness can generally reach about 3-18μm (measured with a fineness scraper). Under the guidance of specific materials, it can be realized 1μm fineness.
There are many types of three roll mills produced by FRANLI, among which the most common models are: TRH (hydraulic three roll mill), TRS (manual three roll mill), and TRL (lab three roll mill). Users can choose rollers of different materials for different viscosities. The most common materials are alloy steel, ceramics, marble, and special high-viscosity materials. Heating three roll mills or powerful three roll mills can also be used.
The scope of application of the three roll mill
The three roll mill is especially suitable for grinding and dispersing materials with high viscosity and high fineness requirements. It is widely used in various liquid slurries and paste materials such as paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, etc. grind.
The main structure of the three roll mill
1. Roller
Three special rollers are used for mixing and grinding materials. The inner cavity of the roller is equipped with a cooling device. The mutual position adjustment between the rollers is controlled by a rotary valve so that the rollers can reach the following working positions as required.
2. Transmission
The power output by the main motor is driven by the belt to drive the gear pair to make the roller rotate in a certain direction.
3. Scraping device
The placement of the scraping blade should be properly selected according to the nature of the material to be ground so that the ground material can be removed as much as possible.
Three roll mill features
1. The roller of the three roller mill is made of the centrifugal casting of chilled alloy cast iron, and the surface is thermally sprayed with nickel alloy powder into a bimetallic chilled alloy, which has high hardness, impact resistance and wear resistance.
2. The transmission system adopts a multi-row chain soft start, the transmission efficiency is high, and the gears are immersed in lubricating oil, which prolongs the service life of the machine to the greatest extent, and reduces noise and energy consumption. The roller is made of wear-resistant alloy steel, which has a long service life lasting.
3. The diameter of the roller is ground with high precision, which is precise and fine so that the grinding fineness of the material can reach below 5 μm, and produce uniform and fine high-quality products.
4. Adjust the particle size of the material to be ground by adjusting the gap between the rollers by adjusting the parallel hand wheel screw, which is simple, accurate, and easy to operate. The three roll mill is equipped with a cooling device, which can dissipate the heat generated during the work of the rollers and ensure continuous operation. It is suitable for various varieties and is easy to change colors.

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 For Carbon Black｜High Grinding & Dispersion
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.
Laboratory Three Roll Mill｜PLC Control System & Experimental
The laboratory three roll mill is equipped with the most advanced PLC functions to continuously improve the operability of the most primitive production equipment.
Three Roll Mill For Grease
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 For Attapulgite
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.
Rolls of a three-roll mill
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.
3 roll mill｜Failure of the roll shaft & pulley
The 3 roll mill is a grinding and dispersing equipment, which plays an irreplaceable role in improving the quality of coating products.
