Kiln Network: Why are there main bearing mill smoke, beating phenomenon that happens there may be several reasons: 1, the main bearing is not properly installed. Bearing installation errors, mainly with the journal bearing contact with the arc concentricity tolerance or exceeded the level of degree does not meet the requirements, making the journal and the bearing surface of the gap at the ends are not equal, or pre-watt pressure, not after the tile mouth contact with or in the opposite, i.e. the journal and bearing contact with uneven. Thus, the journal and the bearing contact area is reduced, the contact pressure is concentrated into a few parts, the lubricating oil can not enter the contact point, the journal and bearing direct friction heat, the lubrication oil smoke. Treatment approach is to stop the mill running, adjust the bearing seat, modified or re-scraping bush. 2, cylinder or hollow journal deformation. Mill cylinder due to manufacturing quality or in the course of frequent disassembly liner and welding, gas cutting, tapping, etc. deformation, so that circular cylinder becomes an ellipse. If the deformation is too large, the cylinder body to the center of gravity of the media and minerals rotary cylinder centerline distance, i.e. the eccentricity of rotation of the plane with the cylinder changes periodically. As a result of the media mill and mineral suffered eccentric gravity distance changes periodically. Because torque is equal to the size eccentric weight and minerals medium eccentricity weight of the product, when the medium and minerals in the longitudinal direction of the cylinder ellipse, the eccentricity becomes large, the eccentric weight torque becomes large; when the medium and minerals in the minor axis direction of elliptical cylinder, the eccentric distance is reduced, the eccentric weight torque reduction. This periodic change to the main load bearing on the formation of the impact, the journal of the neck to swing increases, produce beats and cause fever. Deformation of the hollow journal, roundness exceeds the allowable range, the tendency of the journal and bearing clearance with periodic changes can also generate a liquid friction, lead to heat smoke. When the cylinder or hollow journal after deformation, the mill power consumption will change periodically. Deformation is too large, the power consumption significantly increased, resulting in motor overload. Reform processing depending on the extent of deformation. If the barrel distortion is not too serious, can be repaired through the campus, excessive deformation shall replace the cylinder. Journal deformation may consider processing repaired or replaced. 3, the oil viscosity is not pure or do not meet the requirements. When the lubricating oil viscosity impure or unsuitable, the friction increases, fluid friction is destroyed, causing temperature increases, the occurrence of Burnt accidents. Treated the same way with the shaft temperature is too high.
