The invention provides polymer raw material pulverization equipment and method. Polymer raw materials are added into a chamber of the pulverization equipment, a rotating shaft is arranged in the chamber of the pulverization equipment, the rotating shaft comprises a feed zone and a pulverization zone, a thread is arranged in the feed zone, and under the circumstance that the rotating shaft rotates, the polymer raw materials are driven by the thread of the rotating shaft to advance along the chamber; pulverization blades are arranged in the pulverization zone of the rotating shaft, and after advancing to the pulverization zone, the polymer raw materials are smashed by the pulverization blades. The polymer raw material pulverization equipment and method have a good pulverization effect and high pulverization efficiency and can be applicable to a continuous production line.
