A powder particle shaping device includes a closed cavity capable of changing between multiple shapes as an external pressure changes, and the closed cavity compresses and moves powder particles with which the closed cavity is filled full while the shape changes. A powder particle shaping method is further provided, which includes a. filling a cavity full with powder particles to be shaped; and b. applying a varying external pressure to make the cavity change repeatedly between multiple shapes, thereby making the powder particles under compression move and be subject to friction, where the cavity is kept in a closed state during an effective processing process. The shaping device and method have highly controllable shaping processing intensity of powder particles and stable processing strength, and thus are applicable to shaping and pulverization of various powder particles, and also applicable to pulverization and further shaping processing of dispersed agglomerates.
