Benefits Of Vertical Spindle Coal Mills

vertical coal mills - bvkdenhaag. In a vertical coal mill, drying, grinding, and separating/classifying of coal can be done simultaneously. Hence, production and energy efficiency is higher than those of a tube mill. The vertical coal mill works as follows: Wet coal is feed from the upper part or side of the mill onto the rotating table.

monitoring philosophy. A steady-state Mill Mass and Energy Balance (MMEB) model was developed from first principles for a commercial-scale coal pulveriser to predict the raw coal mass flow rate through the pulveriser. The MMEB model proved to be consistently accurate, predicting the coal mass flow rates to within 5 % of experimental data.
