nozzle ring velocity calculation in vertical roller millINTRODUCTION The vertical roller mill is the appropriate equipment for Reducing the gas speed in the nozzle ring (adjustment of the open area) The required gas flow rate through the mill has to be calculated through a heat balance.

1. Introduction

The headbox slice is also known as the nozzle and consists of a top lip and a bottom lip. The distance between the top lip and the bottom lip is known as slice opening. Slice opening controls the stock velocity and the angle of impingement of stock on the wire. The slice opening is crucial for paper formation and dewatering on wire. The bottom lip is stationary whereas the top lip is

steps of reheating and rolling. The consequent advancement was the direct strip casting of metals (DSC). This category includes several different processes, which all have the same task: the production of metal sheets directly from the liquid phase. One of those processes is the vertical twin roll strip casting, which will be treated in this work.
