With a vertical roller mill with integral classifier the fine-ness of the finished product is set primarily by the rota-tional speed of the caged rotor in the dynamic classifier.

Our flagship mills are centrifugal ring-roll pulverizers – equipped with three pendulum roll assemblies suspended from a rotating carrier. Leveraging centrifugal force created by the rotation of the carrier, the roll assemblies swing outward causing the roller at the bottom of the roll assembly to rotate against the inside of the stationary ring.

Vertical Roller Mills Classifiers. Dynamic technology: Solutions through trustworthy innovations. Since 1996 Loesche have been using dynamic classifiers of the LSKS series (LOESCHE bar cage classifier) in virtually all mills. The LSKS classifier has proven itself as an excellent separation machine with a high selectivity for mill product.

A Loesche LSKS dynamic classifier (Figure 1) was retrofitted to each of four Babcock ' Wilcox (B'W) Model 10E10 ring and ball pulverizers at E.ON's Ratcliffe-on-Soar Power Station in the UK.

In a vertical coal mill, coal is often ground at the bottom of the classifier and then the pulverized coal particles are blown up to the rotating impeller mounted at the top. So far, most of the experimental measurements and numerical simulations have been conducted only at a given inlet condition of the incoming two-phase flow from the bottom ...

To understand the performance of a vertical roller coal mill, the real operational tests have been performed considering three different coal sources. Obtained results indicate that grinding pressure, primary air (PA) temperature and mill motor current have a tendency to rise by increasing coal feeding mass flow rates for all used coal.
