A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING .

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 .

Calculate OEE – Definitions, Formulas, and Examples | OEE

Simple Calculation. The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. Fully Productive Time is just another way of saying manufacturing only Good Parts as fast as possible (Ideal Cycle Time) with no Stop Time. Hence the calculation is: OEE = (Good Count × Ideal Cycle Time) / Planned .

Mill (grinding) - Wikipedia

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 processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Rod mills, how they function - Mine Engineer.Com

The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size. The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill.
