Points forts de la performance

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.

Avantages liés à l'utilisation des machines Keestrack

Une technologie mobile

Chez Keestrack, nous savons à quel point la mobilité est importante pour les propriétaires et les exploitants, et cela se reflète dans la conception et la fabrication de nos machines. Notre objectif est de réduire au minimum les temps de mise en place, d'alléger le poids et d'encombrer le moins possible, afin que vous puissiez être opérationnel le plus rapidement possible.

Surveillance à distance

Avec des flottes importantes et de nombreux sites en activité, il est essentiel que les propriétaires connaissent la localisation et l'état de leurs machines en temps réel, 24 heures sur 24.

Systèmes d'entraînement

En 1999, Keestrack a lancé un système d'entraînement diesel-hydraulique à détection de charge qui a permis de réaliser une économie de carburant de 25 % par rapport à la concurrence.

Rendement de carburant

Nous savons que nos clients ont besoin d'une puissance et de performances exceptionnelles, mais ils souhaitent également réduire leurs dépenses en carburant et leur empreinte écologique.

Réduction des coûts

Le prix d'achat ne représente qu'une partie du coût total de possession. Sur toute la durée de vie de votre investissement, les coûts d'exploitation peuvent s'accumuler et, à terme, nuire à votre compétitivité.
