An air classifier is one of the main and effective device in cement industry. In this study, a three-dimensional, steady and two-phase (solid-gas) computational fluid dynamics (CFD) simulation was ...
The model of the turbo air classifier is established using Solidworks software. The turbo air classifier is 824 mm high and the outer diameter of the cylinder is 200 mm; the coarse powder collection funnel is 200 mm high; the cross-section of the air inlet is 50 mm wide and 34 mm high; the air intake volute
different particles were analyzed, and the mechanical structure of the classifier was also modified to achieve high separation efficiency. Therefore, a novel high-efficiency dry beneficiation technique was advanced for coarse coal slime. Key words: pulsing air; coarse coal slime; DEM-CFD; separation 1 Introduction

Fine product leaves the classifier through the central outlet with the primary airflow. The AVEKA CCE Classifier falls under the definition of centrifugal air classifiers, which
ers. Hence, the flow field distribution inside the classifier with a downward air inlet re-mains unclear. For a high-efficiency rotor classifier with a downward air inlet, further study is needed to determine how to ensure the uniformity of airflow distribution near the classifying surface. The rotor cage blade is the core part of the rotor ...
Increased mill capacity can be achieved by upgrading an existing classifier or replacing a current one with a high-efficiency classifier, such as the BLVT. Capacity improvements can be expected in the 15% to 17% range. The superior design provides controlled and guided material flow right up to and through the classifier.
