Condition: new, functionality: fully functional, power: 75 kW (101.97 HP), fuel type: hybrid, color: other, Year of construction: 2025, Equipment: cabin, hydraulics, onboard computer, CONSTMACH DRYMIX 100 is a fully automatic dry type concrete plant without a mixer. Concrete components are transferred directly into the transit mixer after weighing, without any mixing process. This feature provides a significant advantage, especially in projects where concrete needs to be transported over long distances. DRYMIX 100 offers high efficiency and durability thanks to its fixed, non-mobile structure, and can be used safely in many regions of the world due to its adaptable design for different climatic conditions. This model can be integrated with cement silos with capacities ranging from 50 to 500 tons. When supplied in cement bags, it is easily transferred to silos thanks to the blasting bunker and silo filling systems. In plants used in cold regions, the system is heated with hot steam generators and insulated panels, while in hot climates, concrete temperature is maintained at the ideal level with cooling units. Furthermore, aggregate pre-feeding systems eliminate the need for a feeding ramp, saving space on site. The user-friendly automation system is supported by top-class SIEMENS and SCHNEIDER brand electronic components. The PLC control system manages the production process fully automatically and ensures maximum accuracy with high-precision weighing systems.
