introduction of roller mining equipment

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

Chapter 1 — PREFACE / INTRODUCTION 1 1. PREFACE / INTRODUCTION 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 -
