This utility model relates to the technical field of waste
tire recycling equipment, and discloses a
grinding device for waste tire rubber
powder, including a
grinding body, a feed inlet, a
discharge conveyor belt, a first drive mechanism, a second drive mechanism, a return
pipe, and a return
auger. The feed inlet is located at the top of the
grinding body, the
discharge conveyor belt is installed at the bottom inside the grinding body, the first drive mechanism is installed on one side of the grinding body, the second drive mechanism is installed below the first drive mechanism, the return
pipe is installed on the other side of the grinding body, one end of the return
auger is connected to the return
pipe, and the other end of the return
auger is located on one side of the feed inlet. This waste tire rubber
powder grinding device grinds tire blocks using grinding rollers. After grinding, the tires fall onto a screening plate, where large rubber particles and rubber
powder are separated, improving the separation efficiency of rubber powder and particles and reducing the
noise generated during equipment operation.
