A typical compact rice mill consists of a 6inch diameter x 6inch wide rubber roller husker, and a friction whitener. The friction whitener has a very similar design configuration as the Engleberg except that is has no husking knife. The milling performance of the compact rice mill is superior to the single pass Engleberg huller.

How do Rolling Mills Function? Rolling mills always use a minimum of two rollers, regardless of the number of rollers used. A set of rotating rollers grips the material and propels it forward as it moves through the process. After that, the material is forced to pass through an opening thinner than its initial thickness.

Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
