Overview

Aggregates

Recycling

Sand & Gravel

Quarrying

The new Keestrack I4e tracked mobile reversible horizontal impact crusher can sustainable recycle the best quality end products at the lowest production costs with ZERO carbon emission due to plug-in functionality.

Thanks to the innovative RIC (Reversible Impact Crusher) technology, this machine can be used very flexible in secondary and tertiary crushing of rock and recycling building materials (e.g., Sand & Asphalt).

Capacity up to 250 t/h

Weight 42 t / 46 sT

Inlet 250-450x670mm 10"-18"x27"

Feed size up to 250 mm / 10"

Produces best quality end products at the lowest production costs with zero carbon emission due to plug-in functionality.

The I4e has less wear, better quality of end products (grain shape) and significant energy savings compared to mobile cone or vertical impact crushers.

Ensures consistently high-quality end products of up to 0/2 mm in closed circuit.

Performance highlights

The Keestrack I4e tracked mobile reversible horizontal impact crusher can sustainable produce the best quality end products at the lowest production costs with zero carbon emission due to plug-in functionality.

Due to the innovative Reversible Impact Crusher technology it can be used in secondary and tertiary crushing

The I4e is an alternative to mobile cone or vertical impact crushers. It has less wear, better quality of end products (grain shape) and significant energy savings, from 30%- 40% compared to cone and VSI impact crushers

The I4e allows a feed size up to 250 mm and ensures consistently high-quality end products of up to 0/2 mm in closed circuit. Producing very small fractions is possible with only one machine.

Electric drive system: plugged in, backed up by a drop off engine/gen set unit which can generate sufficient electric power to drive several e-driven machines

Benefits of using Keestrack machines

Mobilní technologie

At Keestrack we understand how important mobility is to owners and operators, and this is reflected in the design and construction of our machines. Our aim is to minimize set up times, reduce overall weight and size, and get you up and running as soon as possible.

Dálkové sledování

With large fleets and multiple sites in operation it is essential that owners know the location and status of their machines in real time, 24 hours a day.

Drive systems

In 1999 Keestrack introduced a load sensing diesel/hydraulic drive system which resulted in 25% fuel savings compared to competition.

Fuel efficiency/účinnost paliva

We know our customers need exceptional power and performance, but they also want to lower their fuel costs and reduce their environmental footprint.

Úspora nákladů

Purchase price is only part of the total cost of ownership. Over the lifetime of your investment, operating costs can add up and ultimately reduce your competitiveness.
