The invention provides a bowl mill. The bowl mill comprises a motor, a frame, a cylindrical shell and steel balls in the cylindrical shell. The cylindrical shell rotatingly fits to the frame through rotation shafts at two ends of the cylindrical shell. An output shaft of the motor is connected to the rotation shaft at one end of the cylindrical shell through a coupler. The cylindrical shell is provided with a feeding inlet and a discharge outlet. The cylindrical shell is uniformly provided with three circular cavities along a length direction. The outer wall of the cylindrical shell is provided with a water shovel bucket. The interior of the water shovel bucket corresponding to the three cavities is provided with three water inlets communicated with the three cavities. One side of the cylindrical shell opposite to the water shovel bucket is provided with water outlets communicated with the cavities. A water tank matching with the water shovel bucket is arranged below the cylindrical shell. The bowl mill can realize synchronous bowl milling and processed material cooling so that material processing efficiency and processing quality are guaranteed.
