In the field of hot mix asphalt (HMA) production, Fujian TieTuo Machinery Co., Ltd. (TTM) has established itself as a pioneer thanks to its modern technological foundation, smart integrated solutions, and sustainable development orientation. With over 20 years of experience and a presence in more than 60 countries, TTM is a reliable strategic partner for global infrastructure and urban contractors.

1. Modern Manufacturing Facility – The Technological Heart of TTM

TTM’s factory in Quanzhou (Fujian, China), spanning 200,000 m², is equipped with highly automated production lines, including:

Smart laser cutting machines, robotic welding and cutting equipment

CNC painting and boring lines;

Smart storage systems and digitized production management;

6S management process: Sort – Set in order – Shine – Standardize – Sustain – Safety.

This system enables TTM to enhance productivity, strictly control quality, and shorten delivery times.

2. HMA Mixing Plant Technology – Optimizing Production Efficiency

Key plant series:

Key components and outstanding technologies:

Drying drum made of Q355B steel (wear-resistant, high-temperature resistant) with an asbestos-free aluminum silicate insulation layer.

Robot-welded mixing chamber, asymmetrical mixing arms, high precision, ensuring high homogeneity in HMA products.

Weighing and batching system with extremely low error (≤ ±0.1% for bitumen and mineral filler), integrated with flexible formula adjustment features.

3. Self-Designed Burner – TTM’s Distinctive Technological Mark

TTM’s outstanding difference lies in its self-designed and manufactured burners, which deliver high combustion efficiency, optimize fuel consumption, and perfectly match the drying drum structure of the plant.

– Oil firing: burns both F.O (fuel oil) and D.O (diesel oil).- Liquefied gas firing: LNG, LPG, CNG.- Integrated firing: Oil and gas

Outstanding advantages:

• TTM’s burners are self-designed and manufactured, applying automatic digital control technology. This design allows the flame size to perfectly match TTM’s drying drum size, aiming to minimize fuel consumption. The burner is capable of burning various types of fuel such as FO oil, DO oil, and natural gas.
• The blower and oil pump use frequency inverter control (Schneider, France). The fuel-to-air ratio is controlled and adjusted via the frequency inverter, with digital display on the screen, providing easy operation and fuel savings.
• TTM equips its burners with two oil pump motors, allowing the remaining pump to be used if one fails.
• TTM burners operate on the principle of differential pressure, which allows the oil pump to work more smoothly and extends its lifespan.
• TTM designs sliding rails, facilitating the movement of the burner for inspection, maintenance, and servicing.

Optimized for plant design: Flame size matches the drying drum for more efficient heat transfer.

Smart digital control: Uses Schneider (France) frequency inverters to precisely adjust the air/fuel ratio.

Multi-fuel capability: FO oil, DO oil, liquefied natural gas (LNG), LPG, or integrated firing mode.

Backup and safety system: Features 2 oil pump motors operating alternately; sliding rail design for convenient inspection and maintenance.

Actual fuel savings: Consumption is only about 4.5–5.5kg of F.O oil per ton of HMA – lower than the international average.

With its synchronized design and comprehensive control, TTM’s burner not only saves operating costs but also enhances the quality of the output product – a “game changer” compared to manufacturers using external OEM burners.

4. Energy Optimization & Environmental Protection
TTM places strong emphasis on “green” factors, through:

Baghouse dry dust collection system: uses Nomex (USA) bags, heat resistant up to 235°C, with cyclical self-cleaning and up to 3% increased thermal efficiency.

Optimized hot air duct design, reducing heat loss;

Ability to reuse collected dust as mineral filler, saving costs and reducing environmental emissions.

5. Smart Control – Flexible and Powerful
PLC Control System:
Developed in-house by TTM, supporting 4 languages: Chinese – English – Russian – Thai.

User-friendly interface, capable of automatic / semi-automatic / manual control.

Easy mixing formula setup, maintenance reminders, data logging, and report printing.

Integrated dual computers, supporting simultaneous operation by 2 operators.

Components:
Frequency Inverter: Schneider (France)

Electrical Equipment: Siemens (Germany)

Weighing Sensors: Transcell, Mettler Toledo (USA)

6. HMA Recycling System – The Inevitable Trend of the Future
TTM is a leader in China for asphalt recycling technology, providing hot and cold recycling modules that can be integrated with new or existing plants (including those from other brands like Ammann, Marini, Speco…).

Independent RAP screening and crushing system.

Reuse of old HMA mixture up to 40%.

Reduces raw material costs, lowers environmental pollution, and aligns with green building – circular economy directives.

7. Flexible Expansion Options According to Project Needs
TTM understands the diversity of projects and markets, which is why equipment can be customized:

Finished product silos: from 40 tons to 500 tons, for storing HMA for continuous construction.

Bitumen heating by oil or electricity: flexible investment and operating costs.

SBS additive and pigment weighing: suitable for producing Polymer HMA or other special types.

Modular design: easy installation, shortening construction time.

TTM technology is not just about modern equipment; it’s a comprehensive technological ecosystem, optimized from production to operation, from performance to environmental impact. With its motto “Go Green, Go Further,” TTM is actively contributing to the sustainable development of the global infrastructure industry – and its self-designed burner is a prime symbol of that innovative spirit.
