Tubular Ball Mills - ScienceDirect
Mills of large dimensions are designed to have a considerable volume at the two conical sections and therefore carry a significant amount of slurry and solids to affect the overall power requirements to rotate it. Morrell determined the power required by the two conical end sections of a mill in the same manner as the cylindrical section.

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.
Rolling (metalworking) - Wikipedia
Roll forming, roll bending or plate rolling is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands, each performing only an incremental part of the bend, until the desired cross-section profile is obtained.
Introduction to rubber processing and safety issues
This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of
