I will be purchasing a 3 roller mill for disbursing lipstick and deodorant. Is there a certain type that I need for cosmetics. Rollers come in alloy steel, ceramic aluminum and zirconia ceramic. I am just purchasing a lab version to start with. I am concerned that the product will stay hot enough after going through the mill. Do I need a 3 roll mill that is heated?
I would greatly appreciate any feedback and/or tips you can give me on this.
