Home | Torrey Mills - Three Roll Mill

The three roll mill is a dispersing tool. As fine particles tend to agglomerate in traditional agitators, a three roll mill applies tremendous shear force to break apart those agglomerates. With the capability to reduce particles down to 1 micron, the three roll mill is versatile enough for a variety of high shear applications. FREE Brochure.

How the Roller Mills Changed the Milling Industry

The roller mills increased the amount of flour as well as speed up the milling process. Roller mills could produce more marketable flour than millstone ground operation. The first (gear driven) roller mills used in Washburn "A" Mill, Minneapolis, Minnesota. Roller mills used more belt pulley drives with metal shafting and less large gears.

Roll forming - Wikipedia

Roll forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a pre-cut die where a single blank runs through the roll mill, or a post-cut die where the profile is cutoff after the roll forming process.
