Feature:
• High in the etent of mechanization and strong in production capacity.
• The resistance for fluid passing through the cylinder is small. The consumption of power and energy is low.
It has strong adaptability to the properties of raw material. The operation is stable. The cost of operation is cheap. The uniformity of dried substance is good.
