The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is ...

Primary crushing is the first stage in the comminution process and involves breaking down large rocks into smaller pieces that can be handled by the downstream machinery. Secondary crushing, on the other hand, is the second stage in the comminution process and involves breaking down the material further into smaller pieces.
