LOESCHE supplies four vertical roller mills to Pakistan

One high-performance 4-roller mill VRM with a capacity of 450 t/h is to be used there for the grinding of cement raw material to a fineness of 12 % with sieving residue of R 90 μm. Two further LOESCHE mills from the middle performance range and a throughput of 170 t/h will serve for the subsequent grinding of cement clinker to a fineness of 3200 Blaine.

In 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 welldispersed fines out of the mill system.

Vibration Analysis of a Vertical Roller Mill Modeling and In this paper vibration characteristics of a Vertical Roller Mill VRM are studied by using physical parameters of an operating VRM The mathematical model is derived and simulated for a set of working parameters Mechanical properties of the grinding material and the physical .

Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grinding circuits.

01.03.2016re vibration vertical roller mill. Hello Ashkan, The most important factor which determines the level of vibration in a VRM is the thickness and consistency of the grinding bed. The bed thickness may be affected by the following variables;-Feed rate too low, too high or changing too quickly. Particle size of feed too large or too small.
