By the example of the sizing programm of grinding flyash plant
the optimal technique of the production of commodity flyash was discussed. By adding the sizing equipment in the grinding flyash plant
the ability of treatment and productive quality could be raised. By adding grinding equipment in the sizing flyash plant the coarse powdercould be processed into standard products that accord with the second degree of flyash. The coarse powder of different qualities and from different plants make different effects on the quantity of grind system. There is an optimal match between the technical parameters of sizing system and grinding system.
