쓰리롤 밀은 수평으로 놓여진 세개의 롤이 서로 반대방향으로 각각 다른 스피드로 회전하면서 생기는 전단력을 이용한 기기입니다
주로 고점성 물질을 mix, refine, disperse, or homogenize 처리하기 위함입니다
대부분 electronic thick film inks, high performance ceramics, cosmetics, plastisols, carbon/graphite,
paints, printing inks, pharmaceuticals, chemicals, glass coatings, dental composites, pigment, coatings, adhesives, sealants, and foods 부분에서 광범위하게 사용됩니다.

위 그림에서 보듯이, 물질은 feeder roll과 center roll 사이에 붓고, 롤과 롤사이의 좁은간격과 회전력으로 생기는 매우 높은 전단력으로 바인더 속의 pigment particle을 분산합니다.

Lipsticks 의 일반적인 처리 단계
(1) pigment milling,
(2) combination of pigment phase into the base,
(3) molding, and
(4) flaming.

밀링은 particle사이즈를 줄이기도 하지만 그보다 뭉쳐진 안료를 풀어내는 것이라 할 수있습니다
쓰리롤 밀에 의해 처리된 paste의 결과는 보통 20micron 정도가 됩니다

[참고사항]
Combination of pigment phase into the base is a simple procedure. The wax and oil phase are usually melted in a steam-jacketed kettle equipped with a single propeller agitator. Following this, the milled pigment phase is added.

Molding is by use of vertical split molds. Most lipstick formulations mold well between 75 and 85 C.
Pre-heating the mold be around 35 C avoids the formation of “cold marks” on the stick,
and holding the mold at a light angle to the vertical is a technique often used to avoid air entrapment.
Rapid cooling after the mass is poured into the mold of important since it leads to a smaller,
more uniform crystalline, structure, which, in turn, leads to better stability and gloss. Once cooled,
the molds can be spit open and the sticks subjected on to the trays or some other suitable storage
container until they are ready for flaming.

Flaming is a procedure for passing the molded stick through the flame of a gas burner, or series or
burners, to increase the surface gloss. The flames are adjusted to a level just hot enough to just melt
the surface of the stick.
