Aluminum gray ball mill shell assembly

The invention discloses an aluminum gray ball mill shell assembly, comprising a cylinder body, a support base, a transmission gear, a pressing shaft, a moving mechanism and a moving seat, wherein thecylinder body is rotatably mounted on the support base, and the transmission gear is fixed at one end of the cylinder body; the moving seat is slidingly mounted on the support base, the moving mechanism is used for driving the moving seat to move horizontally on the support base; the pressing shaft is rotatably mounted on the moving seat, the axis of the pressing shaft is parallel to the axis of the cylinder body, and the outer surface of the pressing shaft is in rolling friction fit with the outer surface of the cylinder body. The rolling friction fit of the pressing shaft and the outer surface of the cylinder body is adjusted by the moving seat, to press the surface of the cylinder body, thereby preventing the bulging of the outer surface of the cylinder body and the like. 本发明公开了种铝灰球磨机外壳组件，包括筒体、支撑座、传动齿轮、压轴、移动机构和
