Thanks to the RIC, or Reversible Impact Crusher, this machine is very flexible in the secondary and tertiary crushing of rock and recycling building materials, for example, asphalt. The specific design of the reversible horizontal impact crusher with a large variable crushing chamber, powerful rotor and electronically monitored hydraulic gap adjustment allows feed sizes of up to 250mm and ensures consistently high-quality end products of up to 0-2mm in closed circuit.

Secondary and tertiary crushing can be now combined in one highly mobile solution. This makes the I4e a real alternative to mobile cone crushers or vertical impact crushers, especially with regard to its outstanding production capacities from 100-250tonnes per hour.

According to Keestrack, the system offers lower wear, better quality of the end products (grain shape) and significant energy savings in typical applications such as sand production.

As with other Keestrack large crushers, the drive unit with its 447kW diesel engine and 300kVa generator is designed as a removable drop-off module. Electric drives for the crusher, with 160kW of power, feeders and conveyor belts as well as the system hydraulics enable particularly cost-efficient and emission-free plug-in network operation.
