Combined Model of Abrasive Wear of Rotor-Accelerator Blades in a Centrifugal Mill
Source abstract
Abstract
A combined model for calculation of abrasive wear intensity of rotor-accelerator blades in a centrifugal mill is proposed. It involves defining the impact velocity and the attack angle of the particles, calculating the impact-abrasive wear, defining the velocity of the particle along the blade, and calculating the wear under abrading effect. It was stated that the wear under abrasion is by 1.5 times lower than under impact. A good agreement of calculation results with experimental data confirms the adequacy of the combined model.
