Work Principle This line is composed of depolymerizer, classifier, cyclone collector, pulse dust collector, fan, control cabinet and so on. Firstly, the raw material is fed into the depolymerizer to grind and then are brought to the classifier by the effect of fan machine.the products that meet the granularity requirement would be collected by cyclone collector and the big granularity material comes out from classifier mouth, super-fine meterial can be collected by impulse dust catcher and clean air vented through fan machine. Characteristic 1. get the depolymerizer and airflow grader in series to produce positive electrode and negetive electrode material, decrease product energy-consumption greatly and improve the product output. It solve the difficulty of positive and negetive electrode easy smash and low rate of finished product produced by airflow pulverizer. The equipment has the safe, reliable and stable characteristics. 2.the whole product line is running under the negative pressure, no dust overflow and working circumstance becomes more clean. The chroma of powder meets the requirement of circumstance protection. 3.the product line is controlled automatically in the PLC way, that is decrease the working intense greatly and wrong operation manually. It makes the product quality becomes more stable.
