Read MoreIn ball mills where the grinding time is longer than in a VRM excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill In contrast to ball mills VRMs have a very high internal circulation a short mill retention time and a huge number of classifying steps that carry.The modifications include ball mills and vertical mills as well as preheater kiln and cooler upgrades In case of a new calciner (new preheater) the retention time can be selected properly In case of upgrading projects the calciner volume can sometimes be increased to give improved retention time.
Read MoreJan 06 2021 The retention time of the material inside the vertical mill is less than one minute • The blaine size adjustment of the finished product is very flexible reliable and convenient It can be achieved by adjusting the speed of the classifier • Noise is quite lower in VRM when compared to a ball mill.The mill also includes the processes of attrition and impact although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations The mill consists of a rotating shaft with four attached parallel knives and a.
