fly ash beneficiation process can be divided into three steps: crushing, grinding and dressing.
fly ash beneficiation process Flow Chart
fly ash processing plant in China generally use the thick broken, broken and fine broken three sections of crushing flowsheets crushing ore. Thick broken multi use 1.2m or 1.5m gyratory crusher, broken using the 2.1m or 2.2m standard cone crusher, fine broken by 2.1m or 2.2m short head cone crusher. Through the thick broken ore, the size of not more than 1m, and then through the final product, fine crushing, screening into the ore grain size less than 12mm send grinding groove.

China's fly ash grinding process, most use two stage grinding flowsheet, small and medium-sized concentrator is used more for a grinding process. Due to the fine screening regrinding of new technology, in recent years some concentrator by two section has three segments grinding instead of grinding. The grinding equipment generally relatively small, the biggest ball mill 3.6m * 6m, 3.2m * 4.5m maximum rod mill, the largest since the mill 5.5m * 1.8m, 2.7m * 3.6m mill. The grinding of the grading basically is the use of spiral classifier. In order to improve efficiency, to replace the two spiral classifier using hydrocyclone to part of ore dressing plant.
fly ash Separation Flow Chart
Mainly used for separation of fly ash processing magnetite "Anshan style". Because the ore strong magnetic property, good grinding well chosen, domestic magnetic separation plant adopts stage grinding and stage grinding process, the coarse grain disseminated magnetite using the former (a grinding), fine, fine disseminated magnetite (the latter two section or three section grinding).
