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 …
