## MATERIAL RETENTION TIME IN A BALL MILL & VRM Page

· Re: MATERIAL RETENTION TIME IN A BALL MILL & VRM You could do that by measuring the material flowrate Q[tons/h] through the mill as well as the quantity M[tons] of material that accumulates within the mill The retention time, also called residence time, is the ratio (M/Q) [h]

## INVESTIGATION OF FEED DYNAMICS IN CLINKER GRINDING MILL

Keywords: Clinker, dynamics, Feed, mill, residence, time 10 INTRODUCTION The main raw material for cement production is clinker Cement clinker is usually grounded using a ball mill This is essentially a large rotating drum containing grinding media; normally steel balls As the drum rotates, the balls cascade and crush the clinker Fig 1 shows the internals of a typical grinding mill

## What are the vertical mill cement finish grinding

The vertical mill cement grinding power consumption is low, grinding cement does not need auxiliary cooling, and the residence time of the material in the mill is very short, can quickly convert from one species to another species, does not need to be a lot of grinding material out, but also in the production process of rapidly changing product particles Vertical grinding pressure is small
