i. high density hydropulper characteristics: this machine is designed according to hydro-cyclone principle. the rotor adopts double head screw structure. when the rotor is working, high-density pulp circulates radially to accelerate the waste paper hydrating and dissolving speed. ii. automatic rotor drum type molder machine characteristics: 1. large output: 2000-3000pcs/hr 2. energy saving: the fan housing on the top of the molder machine makes the best of the vent gas of drying line. afterheat from vent gas reduces products’ moisture ratio by 15-30%. 3. high finished products ratio: during the molding process, the products have been preheated; moisture ratio is lower than common molder machines. 4. high automatization: there are only 4 or 5 workers every shift. iii. drying line introduction: this line consists of heating system, hot-air circulating system, conveying system, drying system, oil supplying system and controlling system, etc.
