Primary crushing is the first stage in the comminution process and involves breaking down large rocks into smaller pieces of a size that can be handled by the downstream machinery. The purpose of primary crushing is to reduce the size of the material to a level that can be handled by the …

Primary crusher is the workhorse that takes blast feed sizes and turns them into smaller sizes that are manageable for other site components—the belts, the screens, and eventually any secondary crushers—on the road …

 — Primary crushing happens when we take big rocks, even ones bigger than a meter, and make them into smaller bits. These bits are often between 150 and 200 mm. This step is very important. It makes the rocks smaller. This helps the next machines work better at crushing or grinding them. Or, we can use these smaller pieces right away for …
