Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a sealed sand mill. Background technique [0002] The grinding machine is mainly composed of a transmission belt and a drive roller, an abrasive belt tension roller, and a drive flower roller motor. The motor is directly driven by a belt to drive the abrasive belt to grind the surface of the board. Because the motor has no speed regulation function, the surface texture of the produced strips varies. When the motor is running, the sealing of the casing is not good, resulting in debris blocking the spindle after long-term use. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a sealed sand mill, which has the characteristics of compact structure and good sealing performance. [0004] In order to solve the problems of the technologies described above, the present invention provides the following t...
