The kneading process of powders and highly vicious fluids is widely used in various industries. In recent years, it has become recognized that the performance of the kneader influences the quality of the products and that advancement of kneaders is much sought after.<BR>In this work, we studied the influence of kneading conditions, such as the rotational speed of the blade, the geometrical configurations of the kneader and the size of the vessel, on the mixing process of wet particles in a double-blade kneader based on the scale of segregation, S_S, of the tracer concentration. An equation was proposed to express the influences of the kneading conditions using the power consumption per unit volume, apparent viscosity, size ratio of the kneader, dimensionless effective shearing area. It was found that this equation could estimate based on S_S, the time and power consumption necessary to attain a desired mixed state for different types of kneaders, with an error of ±20%.
