Wet grinding machine adopting disc type structure

A wet grinding machine adopting a disc type structure comprises an electromotor (1), a speed reducer (2), a main shaft (5), a grinding disc (6), a spacer bush (7), a frame (3), a feeding device (9), a cylinder (8) and a separation device (4). The wet grinding machine is characterized in that a sorting device (10) is arranged at the upper end of the spacer bush (7) and comprises an upper disc (11), a lower disc (12) and sorting blades (13) uniformly distributed between the upper disc (11) and the lower disc (12), and the two ends of each sorting blade (13) are respectively welded with the upper disc (11) and the lower disc (12). With the rotation of the sorting device, the blades with certain angles drive slurry to rotate. The upper slurry flows from inside to outside, and particles with larger particle size can not pass through the sorting device and fall into a grinding medium for re-grinding. The disc type wet grinding machine has sorting function, so that the finished product has high quality and is stable
