The beater wheel mill grinds the fuel to the required fineness and evaporates excess moisture from the fuel, while also ensuring the coal-air mixture is drawn into the combustion chamber. The bearings must withstand the harsh conditions at the limiting operating speeds, loaded both by external loads and by the mill wheel's unbalance.

A numerical investigation is presented for a two-dimensional simulation of the gas flow field and of the dynamic behavior of lignite particles inside Beater Wheel mills with classifier, installed in large coal-fired plants. A large number of representative particles are tracked using Lagrangian equations of motion, in combination with a stochastic model for particle turbulent …

The beater wheel mills built by ALSTOM Power Stuttgart are designed for maximum productivity. In nearly all major atmospheric, -lignite-fired steam power plants, the crude lignite is dried and pulverised in ALSTOM beater wheel mills. The beater wheel mill sucks hot flue gases from the cumbustion chamber through the flue gas pipe to dry the coal ...

The mill has a lignite throughput of 170 tons per hour, corresponding to about seven truckloads of 25 tons each. Technical data • Gas throughput 535 000 m3/h • Beater wheel diameter 4,30 m The beater wheel is cantilevered. This permits easier access to the mill's wearing parts and consequently time and cost saving bearing replacement.

Beater wheel mill with staged grinding. In the case of lignite with high hardness and poor grindability, the beater wheel mills with staged pulverizing/grinding can be used to achieve the required fineness. These mills are designed without classifiers.

A beater wheel mill crushes, shatters, or pulverises lignite upon impact. The fineness of pulverised coal is usually assessed on the basis of the residues on the 1 mm sieve. The typical values for pulverized lignite are well below 10% (usually between 3% and 6%), depending on quality of coal, the combustion system and boiler size [33] .
