Primary, secondary, and tertiary crushing are three stages in the comminution process that break down large rocks into smaller pieces of varying sizes. Each stage uses different types of crushers and has distinct advantages and disadvantages. This article provides a comprehensive guide to primary, secondary, and tertiary crushing.
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 converts the feed size to one that is acceptable to the secondary crusher.
