Fiber dispensing machine

Fiber dispensing machines automatically measure and add fibers to concrete, ensuring precise, efficient, and consistent reinforcement.

Overview

Fiber dispensing machines, also known as fiber dosing systems, are used to automatically add steel or synthetic fibers to concrete mixtures in precise proportions, enhancing durability, crack resistance, and structural integrity. These machines are widely used in industrial floors, tunnels, bridges, precast elements, and screed applications.

Types of Fiber Dispensing Machines

Portable Systems: Lightweight and movable, suitable for small-scale or on-site applications. They can handle plastic or synthetic fibers and are easy to transport between plants or job sites. Stationary Systems: Permanently installed in a concrete plant, often integrated with the plant's batching computer system.

These systems are ideal for high-volume production and can handle multiple fiber types simultaneously. Integrated Systems: Fully automated machines that work with existing batching plants, allowing real-time data sharing and precise control over fiber dosing.

How They Work

Fiber dispensers typically consist of a hopper or cylindrical container with a spiral feeder coil and vibrators to move fibers through the system. Fibers are loaded from bags, boxes, or bulk sacks, and the machine uses load cells or weighing instruments to dose the exact quantity required. The fibers are then fed directly into the mixer, onto the aggregate belt, or into weighing bins.

Advantages

Accuracy and Consistency: Automated dosing reduces human error and ensures uniform fiber distribution. Efficiency: High feed rates allow large volumes of concrete to be processed quickly. Cost Savings: Bulk fiber handling reduces material costs and labor requirements.

Safety: Minimizes manual handling of fibers, reducing workplace hazards. Integration: Can be connected to plant control systems for real-time monitoring and data collection.

Applications

Fiber dispensing machines are used in projects requiring high durability and structural performance, including: Industrial and commercial floorsBridges and tunnelsPrecast concrete elementsScreed and overlay applications These machines are suitable for micro and macro synthetic fibers up to 30 mm, steel fibers, and even fiber “pucks”. In summary, fiber dispensing machines provide a precise, efficient, and safe method to incorporate reinforcement fibers into concrete, improving both quality and productivity in construction projects.
