For the pulping equipment, the rotor drum continuous pulper is a direction ofdevelopment; for the screening equipment, the structure of the screen frame, the precision of the screen slot and the combination of the stages ofscreens are paid more attention; for the floatation tank, Ecocell type floatation tank is the most common, but the new flotation column will bedeveloped in the future; for the heat dispersion equipment, the more perfect disc type heat dispersion system is among the development trend.In a word, low energy consumption, high efficiency, automation, continuousness, large specification and high yield are the trend of development.展开更多
