The basic principle behind the wind mill is that the wind as an external force changes the static force to a kinetic force(from rest to motion).This kinetic energy rotates the wind mill blades
The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.

The major components of a rolling mill consist of the following: Rolling stand or roll housing Requires very rigid construction; Roller table For material movement in the rolling mill; Descaling device For removal of scale before rolling; Shears to cut the steel materials at different stages of rolling
Roller mills are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others. Roller grain mills are an alternative to traditional millstone arrangements in gristmills. Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the mining and processing of ore and

Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the rollermetal interfaces.
Fundamentals of Rolling presents the theoretical knowledge of longitudinal rolling in a comprehensive procedure. This book discusses the basic theory and principles of rolling processes. Comprised of seven chapters, this book begins with an overview of the three principal methods of rolling, including longitudinal, transverse, and skew rolling processes.
For all kinds of rolling mills, whether roughing mill, hot rolling mill, or finishing mill, rolling is the simplest method of shaping steel. In this process, materials are being passed between two rolls, named work rolls. The rolls rotated at the same speed but in opposite direction; clockwise and counterclockwise.

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high load.

The material is rolled both in forward and return in three high rolling mills. At first, it passes forward through the last and second roller and then comes back through the first and second roller. In that mill, the thickness of the material is reduced and being uniform by each pass.
mill and control must be based. Rolling theory can be divided into two broad and general cate gories, that which applies to hot rolling and that which applies to cold rolling. In hot rolling the yield stress characteristic of the metal is strain rate dependent and frictional force between the roll and stock is high.
