| Abstract: | The optimum processing parmeters that ultrafine SF pulverized coal is prepared by ZM80 vibration mill are reseached on the basis of the specific particle size and distribution coefficent by use of orthogonal experiments from two aspects of bag-collected and cyclone-separated ultrafine pulverized coal, The results show that the rotational speed of the classifier, feed current, secondary airflow and modification agent are key factors which have a influence on the classification efficiency of the classifier, specific particle si/e and distribution coefficient of pulverized coai |
