These beater wheel mills are used to pulverise the crude lignite needed to generate steam. Hot flue gas is sucked into the beater wheel mill to dry the coal. While the coal is being pulverised, the coal dust is mixed with the flue gas, resulting in a high drying efficiency. The lignite/flue gas mixture is blown to the pulverised coal burner... This mill uses central horizontal shaft which has a number of arms, and a beater of different design is attached to these arms to beat the coal to be pulverized. High speed impact mills are mainly used in pulverizing lignite. Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite. get price

As shown in Figure 1 (left), in existing lignite-fired mine-mouth power plants in Europe and Australia, high-temperature combustion gas (approx. 1,000°C) is extracted from the furnace to beater wheel mills wherein high-moisture coal is …...The beater mills are unique type of pulverizing equipments which carry out multi functions such as crushing, drying, shifting and transportation of coal, all at a time. The pulverized coal from beatle mill is an air-dust mixture which is burned in the combustion chambers of pulverized coal boiler. In the beater mills, other solids, such

stable flames. In conventional lignite-fired units, this is generally achieved through simultaneous milling and drying in beater wheel mills in which hot furnace gas of ~1000°C drawn from the upper part of the boiler furnace is circulated. In this method, the energy used for drying lignite is the high grade heat in the...Beater wheel mills in lignite power stations usually have a flue gas recirculation duct which allows the use of hot flue gas to dry the lignite during the grinding process. The beater wheel itself is grinding element as well as mill fan at the same time. The speed of the wheel determines not only the crushing process of the lignite but also ...
