Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grinding roller repair, and specifically relates to a shaping equipment for grinding roller repair of a coal mill. BACKGROUND

[0002] The coal mill is a machine for crushing and grinding coal blocks into coal powder, and it is an important auxiliary equipment of the coal powder furnace. There are various types of coal mills, such as the vertical mill, the high-pressure suspension roller mill, the medium-speed micro-powder mill, the super-pressure trapezoidal mill, and the Raymond mill. The grinding roller is one of the core components of the coal mill, and its main function is to grind raw materials into a suitable size. The grinding roller crushes and grinds coal by relying on crushing and grinding. The raw coal rotates with the grinding bowl, driving the grinding roller to rotate around the grinding roller shaft. The pressure of the grinding roller on the coal is partly due to the weight of the grinding roller itself and mostly due to the pressure of the spring. The grinding bowl grinds the coal with the grinding roller. The grinding bowl sends the ground coal powder out of the grinding bowl into the primary air flow. The coal powder separator is a device for separating coarse and fine powders. The function of the coal pipe and the Venturi tube is to distribute the ground coal powder to the powder outlet pipe and send it to the burner. During the use of the grinding roller, the grinding roller shaft may break, and personnel are needed to weld and shape the broken grinding roller for repair. Regardless of the repair method, a fixing device is needed to fix the grinding roller to facilitate the repair work of the staff.
