A coal with higher GCV means less coal flow and vice-versa. More coal flow means more volume of air to be handled by the ID Fan, which ultimately affects the power consumption from the ID Fans. Due to change in coal quality there may rise a need of starting or stopping a mill. This affects the percentage APC significantly. Again, the quality of ...

designing and operation of the coal process system. 1. Hazard analysis of the process The process is shown as Figure 1. Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal.
Aug 02, 2013 In Grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery andor mill liner wear and tear.
For high production of crushed coal it is better to use the hammer mills having higher contact surface of hammer.
