Kimera Gravimetric Mixers - Truck mounted or stationary

A Kimera gravimetric mixer is a mobile plant, normally mounted on a truck or trailer, for the continuous production of concrete, mortar, screed, RCC concrete or cold asphalt with a continuous weighing system for aggregates (ZW8 system, Kimera patent) , weighing by deduction of cement and measurement with electromagnetic flow meters of water and additives.

Why a gravimetric mixer is better than a volumetric mixer



VOLUME IS NOT CONSTANT

A Kimera gravimetric mixer doses by weight, a volumetric mixer by volume, but the volume of a material is not constant, in fact it varies according to the compaction (if cement is vibrated, its density will increase), the external temperature and its humidity.



AUTOMATED PRODUCTION CYCLE MANAGEMENT

A Kimera gravimetric mixer is equipped with the latest generation electronic management system that automates the production cycle. A volumetric mixer must be managed manually by the operator, adjusting trapdoors and hydraulic valves.



AUTOMATIC CORRECTIVE ACTIONS

A Kimera gravimetric mixer is equipped with an automatic corrective action system which, based on the data collected by the weighing systems and other sensors, modifies the dosage of the various elements to keep production constant and correct. A volumetric mixer cannot carry out these checks because it does not have an intelligent management system.



QUALITY WARRANTY

A Kimera gravimetric mixer records at least the last 200 production cycles carried out, including the mix design and real quantity of each single ingredient. This guarantees maximum production quality. A volumetric mixer simply cannot guarantee what is produced by not weighing the elements.

ZW8 gravimetric weighing system

All Kimera gravimetric mixers are equipped with 2 independent extraction belts (one for sand and one for gravel) and a continuous weighing system called ZW8 (ZWEIGHT), consisting of two belts, one for each extraction belt, suspended on 3 load cells. ZW8 is the most advanced gravimetric weighing system in the market and guarantees a maximum error of 1%.

Continuous mixing system

The continuous mixing system of Kimera plants is the only one in the world with a double stage. The ingredients arrive in the first auger, equipped with blades and are mixed together. The mix falls into the second auger which continues the homogenization of the mixture up to its discharge.
Both shafts are equipped with interchangeable wear elements in 12/15 mm HARDOX 500 steel or Ni-Hard cast iron, 35 mm thick and 700 Brinnel hardness. This feature allows the lowest maintenance cost on the market.
