Three Roll Mill: Fine Grinding Method for Lipstick

Three Roll Mill

High-quality and delicate lipstick is inseparable from the grinding of the three roller mills. The user grinds the lipstick to the ideal state through the mutual rolling of its three rollers. The working principle of the three roller mill is very simple, mainly through the mutual extrusion of the surfaces of the three rollers arranged in the horizontal direction of the machine and the friction at different speeds to achieve the final grinding effect.

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

Under normal circumstances, the user only needs to grind the material twice to meet the final requirements. Even for difficult-to-grind materials, only need to grind multiple times to meet the requirements. The three roll mill produced by franli can now achieve a final processing fineness of about 1-18µm (measured with a fineness scraper). There are many kinds of roller materials for the three roll mill, such as high wear-resistant alloy steel, ceramic, granite, etc., and high wear-resistant alloy steel can be selected for the grinding of lipstick. In order to prevent metal pollution, users can also choose ceramic material.

The three roller mill has strong applicability and is the main equipment for grinding and dispersing high-viscosity materials such as paint and ink. The three rollers of the three roll mill are mounted on the frame to form two dispersion lines. The first dispersion line is formed between the middle roll and the rear roll, and the second dispersion line is formed between the middle roll and the front roll. Users generally need to add materials to the middle and rear rollers, and rotate the rollers in different directions, so that the lipstick is squeezed between the rollers to achieve the final grinding state.
The production of lipstick is inseparable from the three roll mill, and its ingredients mainly include wax, grease, pigment and pigment. Generally speaking, the user needs to mix the pigment and grease in proportion, and the mixture is ground and dispersed by a three roll mill to make it fully mixed, and then discharged through the discharge port.

After the initial dispersion and grinding of the material, the user needs to mix the uniformly dispersed pigment and oil mixture, the melted wax and the remaining oil, and then grind and disperse the material by a three roll mill, so that after mixing, after the full grinding of the three roll mill, the ideal grinding particle size is achieved, and the general particle size is about 20 microns.

The three roller mill is the most important equipment for dispersing and grinding the lipstick. After the lipstick is ground and dispersed, the user can mold and cool the lipstick through the mold, and then heat and burn it through a special process to increase the color of the lipstick. Not only that, the user can also add a small amount of essence or other fragrance to enhance the final smell of the lipstick.

The three roll mill is mainly suitable for paste or high-viscosity materials that require high dispersion fineness. The material has been upgraded and improved by the engineers of the franli three roll mill, and it is now fully suitable for materials of various viscosities. Users can also choose a hydraulic cooling device, mainly when the center of the roller is in operation, cooling water can be passed through, which has a good cooling effect, and the conventional temperature rise is less than 10 °c. Through the mutual extrusion of the surfaces of the three horizontal rollers, the material enters between the rear roller and the middle roller, and is squeezed by the rollers, the product particles become thinner, and then taken out by the fast roller. The end of the fast roller is equipped with a scraper to make the material is separated from the roller and falls into the collection bucket. The distance between the rollers can be adjusted by hand, and the grinding effect can be achieved by friction at different speeds.

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.

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.
