According to the different grinding fineness and viscosity of the material, we classify the rollers of the three roll mills. The main materials of the rollers are chilled alloy steel, ceramics, granite, and other materials, which are suitable for the grinding and grinding of materials with various viscosities. Dispersion, such as ink, cosmetics, pigments, plastics, soap, ceramics, rubber, paint, chocolate, and other wet materials and some paste materials.
The three roll mill mainly uses the three rollers of its fuselage to squeeze each other at different speeds on the same horizontal plane to achieve the final grinding effect. In general, the roller shaft of the three roll mill adopts a hollow structure, mainly for the convenience of hydraulic cooling, so that individual materials can be affected by temperature and cause deterioration.
Common parts of FRANLI three roll mill
The composition of the three roll mill is generally inseparable from the machine base, guide cover, roller shaft seat, feeding copper knife, discharging knife plate, cooling device, gears, pulleys, etc. The user can choose the appropriate accessories according to the fineness and viscosity of the material, such as the material of the roller, the hydraulic system, the PLC control system, and the loading and unloading equipment. A high-quality three roll mill is mainly composed of a transmission system, a roller shaft, a feeding device, a cooling device, a fineness adjustment device, and a discharging device.
The transmission system of the three roll mill
The premise of realizing the power of the three roll mill is that a suitable motor must be installed in the machine body, and the power is transmitted to the drive shaft through the toughness of the V-belt, and then the drive shaft drives the gear of the fast roll shaft, and so on, to realize the middle roll. The rotation of the shaft and the slow roller shaft completes the entire traditional system.
Roller shaft of three roll mill
The conventional three roll mill is generally made of alloy steel, and its center is hollow. It is often used for hydraulic cooling when the material is grinding. However, due to the difference in the fineness and viscosity of the material, the roller shaft There are also certain differences in the selection of roller shaft materials, such as ceramics and granite. The material and speed of the rollers are generally the most important factors affecting the grinding fineness of materials. The three roll mill produced by FRANLI can reach 1 micron to 20 microns, which can almost meet the grinding needs of various wet materials.
The feeding part of the three roll mill
The feeding part of the three roll mill is mainly composed of copper knives and copper knife brackets, of which there are two copper knives. To prevent materials from splashing or overflowing to both sides due to pressure during grinding, the copper knife is usually installed between the slow roller and the middle roller by the engineer, and its bracket is used to fix the copper knife and adjust the arc of the copper knife. The role of bonding with the surface of the roller, this type of bracket can fix the copper knife very well, and can also easily take out the copper knife for cleaning.
The cooling system of the three roll mill
The composition of the cooling system is mainly cooled by cooling water entering the inside of the roller shaft. This mainly exists when the roller shaft surfaces are extruding from each other. The heat generated by the friction between the contact surface and the material can easily affect some materials. And the other end is equipped with a cooling water pipe so that by adjusting the amount of water, the material can be kept at the required temperature, and finally, a perfect grind can be achieved.
Fineness adjustment of three roll mill
The ultimate goal of material grinding is to obtain the required fineness, which mainly comes from the distance between the rollers. Generally speaking, the user needs to adjust the hand wheel on the screw and the spring between the shaft seat, to force the spring to compress or pop out to realize the fast and slow rollers to move back and forth, to adjust the grinding fineness of the material to be ground.
The discharge device of three roll mill
The discharge device of three roll mill
The discharge device is generally composed of a discharge knife plate and a bracket. When using the three roll mill, the user needs to install the discharge knife plate on the corresponding bracket, and the scraper knife plate is installed on the discharge knife plate, and the user only needs to adjust the corresponding screw to move the discharge knife The plates are tightly connected at the discharge port. This discharge device can discharge the material smoothly.

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.
