Approximation of Partition Curves for Electromagnetic Mill with Inertial Classifier _ Case study

[摘要] The article presents the impact of the separation parameters on the operation of the grinding and classification system using the electromagnetic mill and impingement-inertial classifier specially designed for this machine. Preliminary tests for the classifier have been carried out, and the effect of the separation efficiency on the value of the recycle flow that optimizes the operation of the grinding system is determined. Fourteen experiments were carried out to test and evaluate the classifier's work, with a variety of damping flaps acting on the airflow. The results provide an accurate assessment of the effectiveness and efficiency of the classifier. The approximation of the electromagnetic mill partition curves using the impingement-inertial classifier was performed by using Weibull distribution function.
