| The roller frame hinge seat 20MG30.32.99 of the coal mill is a key mechanical component. It is located at the bottom of the press frame and connects the roller frame to the press frame through the hinge shaft. The main function of the hinge seat is to transmit the loading force from the hydraulic system to the grinding roller, so that the grinding roller can effectively squeeze and grind the coal. In addition, the design of the hinge seat allows the grinding roller to swing freely within a certain range to adapt to the changes in the thickness of the coal seam and achieve more effective grinding. If the hinge seat is worn, it may affect the grinding angle and path of the grinding roller, thereby causing liner collision and vibration. Therefore, the condition of the hinge seat is crucial to the stable operation and grinding efficiency of the coal mill. During the maintenance process of the coal mill, regular inspection, maintenance and replacement of the hinge seat are important links to ensure the normal operation of the equipment. |
