Five and sixroller mills Sixroller mills have three sets of rollers. When using this type of mill on grain, the first set of rollers crush the whole kernel, and its output is divided three ways: Flour immediately is sent out the mill, grits without a husk proceed to the last roller, and husk, possibly still containing parts of the seed, go to the second set of rollers. From the second roller flour is directly output, as are husks

Guides – They are usually used in long mills for guiding the feed material to the roll groove. Work rolls – The rolls which are in contact with the work piece being rolled. Back up rolls – they are intended to provide rigid support required by the working rolls to prevent bending under the rolling loads. They are normally used in flat mills.

The rolls that make up a pair will be 9 to 12 inches (23 to cm) in diameter, and their ratio of length to diameter can be as great as 4:1. It is very important to maintain the alignment between the roll pairs. Sizing of the material is dependent upon the gap between the rolls along their length. If this gap is not uniform, mill performance will suffer, leading to increased maintenance costs, reduced throughput,

Rolls and roll pass design. Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to execute their duty of deforming steel is in many cases largely determined by the roll pass design. The purpose of the roll pass design is (i) production of correct profile within tolerance limits with good surface finish (free from surface defects), (ii) maximum productivity at

· The average reduction is used to decide on the number of stands in the mill, or the number of stands to use when rolling a certain product. An acceptable average reduction is dependent on the type of mill and the product mix. For example, in a low quality mill where the product is predominantly rebar, a high average reduction can be used. On the other hand, a special bar quality (SBQ) mill

You might want to incorporate fixtures, guides, side rolls, and straightening devices where applicable. Most sections require a straightening device after forming to remove unwanted twist, camber, and bow. These straighteners usually are a block type made from aluminum, bronze, or nylon, but rollers also can be used. The key to straightening is to have the device fairly close to the last pass or between the last

In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effect. When the roll deflection during rolling is less than the camber ground on the rolls the resulting sheet will have concave camber. Design of Camber for Two
