| The coal mill sealing bellows MG31.11.05 is a sealing device used in coal mills, especially in the pull rod and other parts. Its main function is to prevent the leakage or entry of coal powder, air and other media to ensure the normal operation of the coal mill. The following is a detailed introduction to the coal mill sealing bellows: Structure and material 1. Corrugation form: The corrugation form of the sealing bellows MG31.11.05 can be annular or spiral. This design increases the softness and elasticity of the bellows, so that it can better adapt to the movement requirements of the coal mill. 2. Material: It is usually composed of longitudinal seam welded stainless steel pipes with an inner diameter of 100 mm to 80 mm. This material has good corrosion resistance and mechanical strength and can adapt to the harsh environment inside the coal mill. Application scenario 1. Pull rod seal: In the pulle rod part of the coal mill, the bellows is used to seal the gap between the pull rod and the grinding chamber to prevent the leakage of coal powder and air. This sealing device can effectively reduce the damage of coal powder to the sealing packing and extend the service life of the seal. 2. Grinding roller sealed air duct: The sealing bellows MG31.11.05 is also used for grinding roller sealed air duct. The corrugation density is 80 to 120 waves on a length of 1000 mm. This high-density corrugated design makes the corrugated tube have better flexibility and expansion space, which is convenient for installation and adjustment. |
