The invention relates to equipment for driving materials to be percussively broken. The equipment comprises a barrel-type shell, a main shaft installed in the middle of the barrel-type shell and driven by a power device, and a plate-shaped hammer installed on the main shaft in the radial direction, wherein vertical inclined chutes are formed in the inner surface of the barrel-type shell, and the upper portion and the lower portion of the barrel-type shell are provided with a feeding box and a discharging port. The plate-shaped hammer in the equipment can impact materials in the rotation process and can also generate relatively strong wind so that the materials entering the barrel-type shell can rotate in the radial direction under the driving of the wind power, and particles with different diameters are mutually impacted broken. In this way, the service life of the equipment is prolonged, and the speed of grinding the materials is increased.
