The recent addition of the Keestrak H4e cone crusher has strengthened our ability to process tough rock while being able to make the most of modern technology and sustainable thinking. One of the major attractions with this machine is its diesel over electric configuration and pre-screening capability. Having the flexibility of a diesel generator running electric motors offers fuel burn efficiency, a good supply of power, and the opportunity to run directly from the national grid if and when this opportunity present it self.
Equipped with a Pre-Screen the H4e can remove feed materials that have a high fines content, improving cone wear life and eliminating product contamination when exact specification is paramount.
Equipped with a Triple Deck Post-Screen the H4e can produce up to three precise end products ranging from ballast to chip products with oversize materials being returned to the hopper for another pass. With 16.2m2 of screen area. the Post-Screen can replace a classifier screen in the processing chain reducing costs and equipment requirements.
This machine is a great fit with our jaw crusher and gives us a lot of flexibility in what and where we are able to crush; and produce.
