AI Technical Summary
In the plastic recycling process, a large amount of waste plastic is easily piled up at once, which affects the crushing and feeding rate. In addition, the dirt and dust attached to the plastic will generate dust during crushing, polluting the air and endangering the health of workers.
A crushing device was designed, comprising a crushing roller, a stirring plate, and a high-pressure nozzle. The crushing roller is driven by a motor to rotate synchronously, and the stirring plate is used to agitate the plastic to prevent accumulation. At the same time, water mist is sprayed through a liquid pump and a high-pressure nozzle to absorb dust.
It improved crushing efficiency, reduced dust pollution, and protected the health of workers.
