Abstract:
     New type devices for sepg. steel balls from the ground material and coarse powder from fine powder, and for sepg. steel segments from the ground material are equipped inside the mill, and the ratio between steel balls and steel segments used as milling media in the three chambers is adjusted to achieve extra fine milling. It may achieve a specific surface area of 8000 cm2/g for pulverized fly ash cement and 5500 cm2/g for other cements. Its features are simple in construction, easy in prodn., and convenient for altering and reequipping the existent tube mill. Besides, the milling process flow is more reasonable and electric energy is saved.
