Reasons for the popularity of FRANLI three roll mills

Three Roll Mill

The three roll mill is mainly used for the refining of high-viscosity materials in various industries such as paint, ink, pigment, and plastic. It is especially suitable for processing products with high viscosity and fine particle size. It is one of the best-wet grinding equipment in the current wet grinding equipment.

  • Safe scraper socket, Emergency-stop
  • Space-saving desktop models
  • Drip tray for easy cleaning

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

Three roll mill is one of the most effective grinding and dispersing equipment for various viscous materials. It is mainly used for grinding various liquid slurries and pasty materials such as coatings, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, etc. Especially for products with high dispersion viscosity, fine particle size, and some materials that are difficult to be recycled by sand mills, the laboratory three roll mill manufactured by FRANLI is mainly used in the manufacture of samples, experiments, scientific research, etc. in the laboratory, while other types of three roll mills are used in the manufacturing activities of enterprises or factory products.

The surfaces of the three rollers of the three roll mill are squeezed together, and the friction generated by different speeds makes the adjacent rollers generate strong shear force, forcing the materials to be completely dispersed and broken.

The three rollers of the three roll mill are installed on the iron frame, and the center is in a straight line. It can be installed horizontally or slightly inclined. Since the machine needs to ensure safety, it is best to install the three roll mill on a level ground or platform. superior. The grinding effect of the three roll mill is achieved by squeezing the surface of three horizontal rollers and rubbing at different speeds. The three rollers are one of the core parts of the three roll mill, which can be hollow and water-cooled. The material is fed between the middle roller and the rear roller. Because the rotation directions of the three rollers are different (the rotation speed increases sequentially from the back to the front), the grinding effect is good. After being squeezed and ground by the roller shaft, the material is scraped off by the scraper installed in front of the front roller.

In general, the roller shaft material of the three roller mill is centrifugally cast with cooled cast iron alloy, and the surface hardness is above 70HS; the diameter of the roller is high-precision, precise, and finely ground, and the grinding fineness of the material can reach 1 micron, so it can be produced Produce high-quality smooth and delicate products.

Product advantages of three roll mill

1. The rollers of the three-roller mill are mainly centrifugally cast with cooled cast iron alloy, and the surface hardness is higher than HS70. Users can also choose materials such as granite and ceramics according to their own needs. It is a high-strength, high-wear-resistant grinding machine. Its toughness will not affect the performance of the roll due to external pressure and temperature. The roll can be hollow in the center or water-cooled to meet the materials that are easily affected by temperature.
2. The diameter of the roller is ground with high precision, which can make the material polishing fineness less than 1um, so that very fine materials can be ground to meet the grinding needs of various industries.
3. A reducer is added to the transmission system of the three roll mill, the output torque is increased, the transmission efficiency is high, the operation is stable, and there is no noise. The parallel flywheel screw can adjust the rolling pitch, which is simple, accurate, and easy to operate.
4. Adjust the size of the material to be ground by adjusting the distance between the parallel handwheel screw and adjusting the roller, which is simple, accurate, and easy to operate.
5. The three roll mill can be equipped with a cooling device, which can largely dissipate the heat generated by the rollers during work, to ensure that the materials affected by the temperature can work continuously for a long time. It is suitable for many varieties and easy to change colors.

Maintenance of three roll mill

1. Under normal circumstances, after the three roll mill has been used continuously for half a year, the user needs to suggest inspection, disassembly, and cleaning of multiple parts of the machine, and also needs to replace new lubricating oil in time to check the smoothness of the oil.
2. During the dismantling and washing process of the machine, if the user finds some problems with the machine, it should be repaired in time. If the roller is deformed during use, stop the machine immediately and grind again. If the roller shaft is ground too many times, and the diameter of the roller shaft is smaller than the requirement, the driving gear will be tightened slowly, and there will be a gap between the grinding rollers, and the gear should be corrected at this time.
3. The front edge of the discharge blade must be carefully calibrated before installation, finely ground, and smooth, and no gaps or cracks are allowed. Once the blade is shortened, you can loosen the countersunk screw and remove it for reuse.

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 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.

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.
