Coal Dust Remediation - FEECO International Inc.

Pelletizing creates round coal pellets and is highly effective in mitigating coal dust issues. Here, coal fines are fed into a pin mixer, along with water or a binder, where they are conditioned into granules. Once granule formation has begun, coal granules are fed onto a disc pelletizer, where they are further grown and rounded into more refined coal pellets. From the pelletizer, they are fed to a rotary dryer, where they are dried into a final product.
