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 crosssection profile is obtained. Roll forming is ideal for producing parts with long lengths or in large quantities. There are 3
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

Fourroller mills Fourroller mills have two sets of rollers. When using a fourroller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits. Flour is sieved out of the cracked grain, and then the coarse grist and husks are sent through the second set of rollers, which

Roller mills are used around the feed mill to perform a variety of tasks. Applications include crumbling pellets, cracking corn, dry rolling and steam flaking grain, and grinding corn, wheat, or milo for mash and pelleted feeds. While each application has some unique aspects, maintenance and operation of the equipment is remarkably similar.
· In this training module, we''ll cover the operation of a vertical roller mill. This mill is commonly used in the cement industry in order to grind raw feed. We''ll describe the general arrangement
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.
