coal mill classifier repair case study

Classification performance of model coal mill classifiers ...

2020-3-1 · The classification performance of a model coal mill classifier with non-swirling and swirling inlet conditions of the bottom incoming flow was experimental and numerically studied. The PIV measurements showed that under different inlet conditions, the flow fields adjacent to two neighboring blades were very different.

2018-1-6 · In this case study an entire vertical spindle mill was modelled to understand the particle flow, coal drying and classification processes occurring within the mill and classifier. Within the mill, there is a complex interaction between hot air and various coal particle sizes with a high moisture content. Primary and secondary classification of the 2-phase mixture as well as moisture evaporation are modelled.
