· by Colleen Suo In December we reviewed KPI-JCI Resource Development Manager Erik Schmitd’s seven best practices for optimal crusher maintenance. This month, we’ll look at some elementary dos and don’ts of crusher maintenance, beginning with horizontal shaft impactors. • Check the rotor for wear after making speed adjustments.

· Types of crushers. Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.

· 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.
