on this fuel. In India, more than 75 % of non-coking coal produced is used for power generation. At present, nearly 200 million tonnes/year of coal is used for power generation and the average ash in coals is invariably above 40%. The majority of non-coking coal reserves in India are inferior in quality because of drift origin.

In order to make the parts move, the vibration must be focused in the desired direction. this is done by mounting the springs on an angle rather than vertically. as the feeder bowl rotates back and forth on its springs the angle causes it to move vertically as well. as it moves forward and up, friction pushes the part forward.
