When classification is to be carried out, the electric lifting lead screw 3 rotates to drive the lifting nut 32 to move downward along the guide rod 33, thereby driving the primary crushing mechanism cylinder body 1 to move downward. The downward movement of the primary crushing mechanism cylinder body 1 causes the discharge plate 4 to move upward relative to the primary crushing mechanism cylinder body 1 under the action of the ejector rod 44, creating a gap between the discharge plate 4 and the inner wall of the primary crushing mechanism cylinder body 1. The ferric poly sulfate particles fall onto the primary filter screen 43 inside the primary classification mechanism cylinder body 42 along the discharge slope 40. Among them, the ferric poly sulfate particles with a particle size within a preset first particle size range are taken as primary ferric poly sulfate particles and fall below the primary filter screen 43 and are output by the primary ferric poly sulfate particle output auger 45 to achieve collection. The ferric poly sulfate particles with a particle size exceeding the preset first particle size range are sent to the secondary crushing module through the primary filter screen 43; During the downward movement of the primary crushing mechanism cylinder body 1, the L-shaped linkage rod 47 drives the gate 48 to move downward to block the communication port 46, thereby ensuring that the ferric poly sulfate particles with a particle size within the preset first particle size range will not directly roll into the secondary crushing module due to gravity. The design of the power assembly and the primary classification assembly can achieve precise control of the flow rate of the ferric poly sulfate particles.
