Lipstick, as a cosmetic, is now popular with women all over the world, but few people know what machine it is made of. Here's how to solve the mystery of the essential machine that makes lipstick.

Phase One: the pigment is mixed with the right amount of grease (the ideal ratio of pigment to grease is two parts grease to one part paint), and then the mixture is milled by three roll mills to disperse the colored polymer evenly.

Phase Two: a well-dispersed mixture of paint and grease is added to the melted wax and the remaining grease (or a small amount of perfume can be added), mixed, and reprocessed through three roll mills, achieving the desired particle size (usually 20 microns). Three Roll Mills is a very effective device for evenly dispersing lipstick pigments.

Phase Three: The lipstick needs to be molded and cooled in a mold.

Phase Four: Burn through the combustion chamber to increase surface gloss. And then you do a nice little package, and that's the lipstick that you see.

Three roll mills are designed for use with highly dispersed, high fineness pasty or high viscosity materials; the roll center can be cooled by cooling water, the normal temperature rise is less than 10 °C, and the quality of the product is guaranteed. The surfaces of the three horizontal rollers are pressed together. The material enters between the back roller and the middle roller. The product is extruded by a roller, the product particles are thinned and then taken out by a quick roller. A scraper is arranged at the end to separate the material from the drum and fall into the collecting bucket. The distance between the rollers can be manually adjusted to achieve the grinding effect by friction at different speeds.

Not only can three roll mills be used in the manufacture of lipsticks, but in many industries, it is indispensable, such as a variety of paint, ink, pigments, plastics, cosmetics, soap, ceramics, rubber, and other liquid size and paste materials.
