Ultra-high performance fiber concrete (UHPFRC) mixers are specialized machines designed to handle the unique requirements of mixing UHPFRC, a high-strength composite material containing steel or synthetic fibers. These mixers ensure uniform dispersion of fibers and achieve the dense matrix essential for UHPFRC’s superior mechanical properties (e.g., compressive strength >150 MPa, tensile strength >7 MPa). Below is a detailed overview based on technical specifications, key features, and industry applications:
1. Types of UHPFRC Mixers
The most commonly used mixers for UHPFRC are planetary mixers and vertical shaft planetary mixers, which combine high shear forces with gentle material handling to prevent fiber balling.
Planetary Mixers (CMP series by CoNele): These feature rotating mixing stars that create a counter-current motion, ensuring homogeneous mixing in shorter times (15-20% faster than traditional mixers).
Models like the CMP500 have a discharge capacity of 500L, mixing power of 18.5kW, and hydraulic discharge systems.
2. UHPFRC Planetary Mixers Key Technical Features
High Torque Transmission: Industrial reduction boxes with high output torque ensure smooth mixing of UHPFRC’s dense matrix. Hydraulic couplers provide overload protection and torque buffering.
3. Manufacturers and Models
CoNele leading manufacturers offer UHPFRC-specific mixers with CE/ISO certifications:
Co-Nele Machinery: UHPFRC mixers uses German technology for high homogeneity and durability, supported by 20+ years of industry experience.
4. Application Scenarios
UHPFRC mixers are critical in:
Bridge Construction: For producing thin, durable bridge decks and corrugated steel culvert liners. Freyssinet’s sprayed UHPFRC technology, for example, uses custom mixers to achieve 6cm-thick linings with 100-year durability.
Industrial Floors: High abrasion resistance makes UHPFRC ideal for warehouses and manufacturing facilities.
Structural Retrofit: UHPFRC’s high bond strength allows it to repair damaged concrete structures, such as columns and slabs, with minimal thickness.
