Horizontal shaft mixers for higher performance


Horizontal shaft mixers are designed to provide fast, consistent and uniform mixing, even in high-volume cycles. Their dual counter-rotating shaft system ensures even distribution of materials, ideal for high-performance industrial plants. Thanks to their robustness, efficiency and low maintenance requirements, these horizontal concrete mixers are the perfect solution for optimising concrete production with maximum reliability and performance.

Features and advantages of the horizontal shaft mixer

The horizontal shaft mixers, also known as twin-shaft mixers, are ideal for large-capacity concrete plants that require homogeneous mixes in continuous cycles. The following are the main features of the horizontal mixers:

  • Counter-rotating twin-shaft system: The two counter-rotating shafts rotate in opposite directions, ensuring a homogeneous and continuous mix, even in high-volume cycles.
  • High-efficiency blades: Equipped with optimised blades, they ensure uniform distribution of materials throughout the mixing process.
  • Ideal for large productions: These mixers are designed to handle large volumes of material in each cycle, making them perfect for industrial prefabrication processes where concrete requirements are very high.
  • Continuous mixing: Its ability to work with continuous cycles improves plant efficiency, enabling faster and more consistent concrete production.
  • Wide, hydraulically operated discharge door: The large discharge door allows for rapid flow of the concrete, optimising discharge times and reducing waiting time between cycles.

      Durability and maintenance of the horizontal shaft mixer

      The horizontal shaft mixers are designed to offer high durability and a low maintenance, making them a cost-effective option for long-term industrial operations requiring large quantities of concrete.

      • Centralised lubrication system: The centralised lubrication system ensures that key components receive the necessary care, reducing maintenance frequency and improving the mixer's service life.
      • Easy maintenance: Thanks to the optimised design of the frame and easily accessible components, maintenance tasks are simplified, allowing plants to minimise downtime and reduce stoppages.
      • Resistance in demanding conditions: Horizontal mixers are constructed from high-strength materials, ensuring consistent performance under intensive working conditions and use.
      • Robust design: Their robust structure allows them to operate in long cycles without compromising their efficiency, which translates into a long service life.
      • Large number of blades and their optimised arrangement: The design of the blades and their orientation guarantee the correct combination of materials during continuous mixing operation. This ensures that the material is mixed properly throughout the entire mixing cycle.

      Customers can customize and select the mixer that best suits their needs, as each product is adaptable to the requirements of the project and their investment capabilities.

      Frequently asked questions

      What is the difference between a horizontal shaft mixer and a vertical shaft mixer?

      The main difference lies in the type of mixing: horizontal mixing is ideal for large volumes and continuous mixing, while vertical mixing is ideal for small volumes and batch mixing. vertical offers greater precision for smaller productions or specific formulations.

      The position of the mixing shaft defines the type of mixer. In vertical shaft mixers, the shaft is positioned vertically in the centre of the mixer, while in horizontal shaft or twin shaft mixers, there are two horizontal shafts and mixing is carried out horizontally.

      What type of concrete can be prepared with a horizontal shaft mixer?
      This type of mixer is ideal for structural, industrial, precast, and high-performance concrete, including formulations with special additives or aggregates.
      How much space does a horizontal shaft mixer require in a plant?
      It depends on the model and capacity, but generally a firm base, space for loading aggregates, unloading and access for maintenance are required. It is advisable to have a suitable technical area.
      What level of automation can be incorporated into these mixers?
      They can be integrated with PLC control systems, automatic dosing, humidity sensors, and remote monitoring to maximise precision and efficiency.
      What is the average service life of a twin-shaft mixer?
      With proper maintenance, these machines can operate efficiently for more than 10 years, even under conditions of intensive industrial use.
