Crushers and grinders are machines that allow you to give materials the size you want. Different crushing systems exist to adapt to each use, for example the primary crusher is used at the start of the crushing cycle to break up blocks of rock. Secondary crushers, tertiary crushers or quaternary crushers are used depending on the desired aggregate size.
There are several types of grinders with different operation.
· Cone crushers compress materials until they burst
· Jaw crushers and impact crushers press down on materials with an impact system
