Feb 17, 2016 The vertical roller grinding mill has used a bucket elevator from the outset for returning the recirculation material. This reduces the amount of air-borne recirculation within the mill, which lowers the pressure loss and improves the smooth running of the mill. The bucket elevator is also a great help dur-ing maintenance work. Mill Maximum 5% 25 mm. Vertical.

Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill. Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed and reject) remain in the mill casing. This situation leads to sampling problems around the equipment.

A roller mill 10 for pulverizing fine material has a grinding mechanism that includes a plurality of grinding rolls 64 and a grinding ring 66 that coact to pulverize material within a mill housing. The grinding ring has an inner grinding surface wherein the inner surface includes an upper vertical portion and inwardly sloped lower portion. The BLVT Classifier is designed to optimize the air and material flow inside the mill and minimize unnecessary internal recirculation. This is accomplished by controlling the gas speed distribution of the classifier from material entry to exit. Grit Funnel controls air and material velocity up to the classifier inlet and through the guide ...
