DOUBLEMIX 90 – Stationary Concrete Plant

KRISMAK DOUBLEMIX 90 is a special production system, rarely seen in the industry, consisting of two independent concrete plants positioned on the same platform. This system, which responds to high-volume concrete production with a total capacity of 180 m³/hour, is equipped with two separate mixers and two independent discharge buckets and can simultaneously discharge to different transit mixers or concrete transfer equipment. The most critical advantage of this structure is the ability to fill two transit mixers at the same time; this significantly reduces vehicle waiting times and noticeably accelerates delivery processes.

The twin mixer architecture of the system not only increases production speed but also enables the simultaneous production of different concrete types. While one of the mixers is used for ready-mix concrete production, the other can be allocated for concrete blocks, precast elements, or special-purpose mixes. Thanks to this flexibility, KRISMAK DOUBLEMIX 90 is among the rare systems that can meet multiple production needs from a single facility. On the other hand, when any breakdown or maintenance-related disruption occurs in one of the mixers, the other can continue uninterrupted production; this makes the facility a reliable choice in projects requiring high continuity.

In terms of mixing technology, the DOUBLEMIX 90 offers wide flexibility. Depending on the type of concrete to be produced and the desired mixture quality, pan mixers, single shaft mixers, twin shaft mixers, or planetary mixers can be integrated into the system. Each mixer type is selected to provide the most suitable homogeneity for specific concrete formulations; this way, high capacity is maintained without compromising production quality.

The cement storage infrastructure of the facility also has a scalable structure according to project-based needs. Cement silos of different capacities ranging from 100 to 500 tons can be included in the system; when cement is supplied in bags, big bag opening and silo filling systems are activated to facilitate the logistics process. Similarly, the aggregate feeding system also has a flexible design. Aggregate pre-feeding systems that eliminate dependence on traditional loading ramps optimize loader usage while also reducing space usage. In cases where the site is of limited dimensions, the skip hoist system is activated instead of belt conveyors and different layout plans are applied to ensure the facility is integrated into the available space in the most efficient manner.

Regarding climate adaptation, KRISMAK offers comprehensive engineering solutions. In regions with freezing cold such as Russia, Kazakhstan, Ukraine, and Northern Europe, DOUBLEMIX 90 facilities are equipped with steam heating generators and insulated panels. In geographies where intense heat threatens concrete quality, such as the Middle East, Gulf countries, and Africa, water cooling systems are integrated to keep concrete components at optimum temperature. This way, the DOUBLEMIX 90 can achieve consistent and high-quality concrete production in different climate zones worldwide.

The automation system that complements all these mechanical and structural advantages is built on upper-class electronic components from SIEMENS and SCHNEIDER brands and state-of-the-art PLC hardware. The advanced software platform, which stands out with its user-friendly interface, enables all production processes to be centrally managed, real-time data to be monitored, and parameters to be precisely controlled. With all these components, KRISMAK DOUBLEMIX 90 is positioned as the indispensable infrastructure solution for large-scale construction projects, offering high-capacity production, operational continuity, and low operating costs under a single roof.
