Assuming that all the masses of a rotor M q are concentrated in the disc part of the rotor and lie in the same plane of rotation. Due to the asymmetric distribution of the rotor mass, the center of gravity deviates from the axis of rotation with an eccentricity of e.When the rotor rotates around the axis with equal angular velocity ω q, unbalanced …
1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent …
