The medium - speed mill hydraulic cylinder is a critical component applied in medium - speed coal mills, mainly responsible for providing the necessary pressure to the grinding roller, ensuring that the coal is effectively crushed and ground between the grinding roller and the grinding disc. It features high pressure resistance, stable performance and precise pressure control, which are essential for the efficient operation of medium - speed mills.

In terms of application scenarios, it is primarily used in thermal power plants, coal - fired boilers and other industrial facilities equipped with medium - speed coal mills. In the coal grinding process, the medium - speed mill hydraulic cylinder adjusts the pressure of the grinding roller according to the coal quality and grinding requirements, so that the coal can be ground into fine powder meeting the combustion standards, thus ensuring the full combustion of coal in the boiler and improving the energy utilization rate.

For installation methods, there are two common types: flange mounting and trunnion mounting. Flange mounting is to fix the cylinder on the mill frame through flanges, which is firm and stable, suitable for occasions with large load and small installation space. Trunnion mounting uses trunnions on the cylinder barrel for installation, allowing a certain range of angular movement, which can adapt to the slight vibration and displacement of the mill during operation.

In terms of structural forms, it mainly has a double - acting structure. This structure enables the hydraulic cylinder to extend and retract under the action of hydraulic pressure, so as to flexibly adjust the pressure of the grinding roller. As for the output type, it is rod output. The piston rod extends and retracts to drive the grinding roller to move, thereby changing the pressure between the grinding roller and the grinding disc.

Optional accessories include a pressure sensor, which can monitor the working pressure of the hydraulic cylinder in real time and feed back the data to the control system to realize automatic pressure adjustment. In addition, a hydraulic lock can be optional, which can lock the piston rod in a certain position when the system is shut down or fails, preventing the grinding roller from falling and ensuring the safety of equipment and personnel.
