【 摘 要 】

The article considers the trunnion of a ball mill in the framework of theory of elasticity, which is subjected to an uneven thermal impact due to the heating of the load. Equations describing the radial displacement of the point inside the trunnion of a ball mill are obtained. The equations describing the movement of trunnion points of the ball mill are derived. The stress-strain state of the trunnion of a ball mill has been determined depending on the temperature of inner and outer surfaces of the trunnion. The deformations and stresses arising on the surface of the trunnion are investigated by numerical methods.
