Primary Crusher an overview ScienceDirect Topics

In general, coal crushers are categorized into two types and three types of primary crushers, as follows: Primary coal crusher: Used for larger coal size. 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 large enough to be handled by a single crusher. The primary crusher
