Keestrack Presents Revised I4e Crusher with Diesel-Electric Drive
Belgian specialist in mobile processing equipment Keestrack has completely overhauled its I4e crusher model. The mobile tracked mobile crusher with reversible impact crusher technology now features an advanced diesel-electric drive and is intended to be an alternative to conventional cone crushers and vertical impact crushers.
Reversible Impact Crusher Technology in Focus
The heart of the I4e is the Reversible Impact Crusher (RIC) technology. This enables flexible use in both secondary and tertiary size reduction of rock and recycling building materials such as asphalt. The special design of the reversible horizontal impact crusher is characterized by a large, variable crushing chamber and a powerful rotor.
Particularly noteworthy is the electronically monitored hydraulic gap adjustment, which allows precise adjustment of the grain size distribution. With feed sizes of up to 250 mm, the system produces consistently high-quality end products down to a grain size of 0-2 mm in closed circuit operation.
Combined Crushing and Screening Technology
The combination of secondary and tertiary size reduction in a highly mobile screening plant represents a technical advancement. This design makes the I4e a serious alternative in the competitive crusher segment, particularly compared to established mobile cone crushers.
Performance Data and Drive Technology
With production capacities between 100 and 250 tons per hour, the I4e is positioned in the mid-range performance segment of mobile crushers. The modular drive concept is based on a 447 kW diesel engine in combination with a 300 kVA generator, which is designed as a removable drop-off module.
The electrical drives for the crusher (160 kW), feeder and conveyor belts as well as system hydraulics enable cost-efficient and emission-free grid operation. This hybrid solution meets current market demands for more environmentally friendly construction machinery.
Market Positioning and Areas of Application
Keestrack is promoting the new development with reduced wear costs, improved end product quality in terms of grain shape, and significant energy savings. Typical areas of application include sand production and the recycling of building materials.
Strategic Repositioning
The complete redesign of the I4e suggests a strategic repositioning. Given the intense competition in the mobile crushing equipment segment and increasing demands on efficiency and environmental compatibility, Keestrack is responding to market pressure with technical innovations.
The emphasis on diesel-electric technology and the possibility of grid operation show that the manufacturer takes the trends toward electrification and hybrid drives in the construction machinery industry seriously. Whether these technical improvements will be sufficient to succeed in the fiercely competitive market for mobile processing equipment will become apparent in the coming years.
