Protecting Equipment from OvercurrentsSafeguarding Equipment from UndercurrentsPreventing Power Outages from Ground FaultsCurrent TransformersCrushers come in several forms and are used to reduce the size of materials. Typical applications include shredding wood as well as crushing rock, coal, and other minerals. They have electric motors sized to the capacity of the crusher. Material is usually fed to them by a conveyor at a rate that provides maximum production capacity and prevents overloading. In the event of an overload, a crusher can stall and jam, resulting in significant downtime to clean the material from the crusher and r..See more on ecmweb
