07-06-2021· The unit processes in coal preparation plants vary, but the following sequence of steps is typical. Crushing and breaking. Run-of-mine coal must be crushed to an acceptable top size for treatment in the preparation plant. Typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. Sizing.

In very simple terms, the process of converting ROM coal into marketable products is called coal preparation. Levels of cleaning. Coal preparation results in at least two product streams, the clean coal product and the reject. Generally, five levels of preparation can be identified, each being an incremental level of cleaning over the previous one: Level 0: At this level, no coal cleaning is done; ROM coal is
