Pin Mill Depolymerization System

After being fed into the grinding chamber by the feeding device, the materials are accelerated synchronously with the high-speed rotating turntable and move outward under the action of centrifugal force. During the process, they collide violently with the pin rods on the turntable and the static disc to realize grinding, with the grinding intensity increasing toward the outer circumference. Both the turntable and the static disc are equipped with three layers of pin rod rings, ensuring the materials undergo sufficient and uniform grinding, and guaranteeing a finer discharge fineness and a regular particle size distribution. The complete system consists of a pin rod mill, a two-stage classifier, a dust collector and an induced draft fan. The pin rod mill accurately controls the D50 index; the first-stage classification removes large particles to meet the D90 requirement, with coarse particles being able to flow back for further deagglomeration; the second-stage classification removes fine powder to ensure the D10 index.

The system is equipped with three independent discharge outlets: the first-stage classification discharges coarse particles, the second-stage classification outputs finished products, and the dust collector collects micro-powder. The classified discharging is accurate and efficient, meeting the refined requirements for the deagglomeration processing of anode materials.
