Our photo this week is a sample of coal fines.
Coal is a reliable energy source used around the world, but its dusty form is less than desirable to process and transport. Low rank coals are especially problematic, as they generate large amounts of dust, resulting in product loss and build up on mechanical components. In addition, coal dust is combustible, making it a hazard that must be addressed.
To combat the issues surrounded by coal, FEECO utilizes the following agglomeration equipment to help customers treat and de-dust their coal fines:
Pin Mixers mix coal dust with a binder or water at high speeds, a process commonly referred to as ‘conditioning.’ This effectively de-dusts coal fines and creates a product that is much more easily handled and transported. Pin mixers are also a quick and cost-effective processing solution.
Pelletizers: Coal can be further processed on a disc pelletizer. After conditioning in the pin mixer, the coal is fed onto a disc pelletizer where it is further rounded into smooth, coal pellets. Finally, the pellets are transported to a rotary dryer for additional processing. Disc pelletizers are particularly advantageous because trained operators can easily control pellet size.
