FAYAT GROUP WHEN THE PRESENT ANTICIPATES THE FUTURE

MASTER TOWER Master Tower is a new milestone in asphalt production. Using RAP and existing materials from pavements of worn road infrastructures, producing low-carbon mixtures (CO₂), and energy savings are hot topics for those who want to produce environmentally-friendly asphalt. Marini Master Tower has simplified asphalt mix production by optimising and rationalising the plant through gas recirculation and making the most of the energy introduced. The result allows the production of new asphalt mixtures containing a percentage of recycled material up to 100%, recovering all the materials from...

WHAT MAKES OUR PLANT UNIQUE Master Tower - Italy

Our technology for the lowest energy consumption Maximum attention to emissions and odours New software developments for the client ASSEMBLY, MAINTENANCE AND SAFETY Plants designed with users for you Savings on the overall cost of each component per ton of HMA \

ENERGY-SAVINGS State-of-the-art drying process THE INNOVATIVE CONCEPT BEHIND MASTER TOWER MARINI’s innovative solution simplifies components that generate heat using just one burner. This system produces energy for heating virgin materials in the first drum. Then, based on the mixture obtained, the necessary amount of heat is transferred to the second drum, which processes only RAP materials. KEY FEATURES 1 BURNER INSTEAD OF 2 (MARINI PATENT) OPTIMISED INSULATION HEAT EXCHANGE OPTIMISATION CONSUMPTION CONTROL OPTIMISED PERFORMANCE 1 burner instead of 2 in counterflow (Marini patent) makes the...

SUSTAINABILITY Thermal protection LOW-EMISSION PLANT Reducing emissions and odours is the most remarkable challenge that asphalt production plants must take on nowadays. INDIRECT HEATING Indirect heating of RAP through HOT AIR and high efficiency of the counterflow drying process FUME RECIRCULATION Re-burning of all the bitumen particles (MARINI PATENT), thanks to an innovative air recirculation system at the RAP drum outfeed EMISSION TREATMENT Complete treatment of all emissions, gases, and odours produced during the plant’s regular operation. Emissions can be conveyed or diffuse: conveyed emissions...

RAP TREATMENT RAP is dried and heated by hot gases from the virgin aggregate drum. Hot gases prevent contact between the burner’s flame and the recycled material and the direct radiation of the flame on the RAP. This way, we limit temperature peaks when heating the recycled material. Thanks to the innovative fume management system, all particles and fumes can be sent back to the drum and immediately introduced behind the burner’s flame. This process reduces emissions and odours in the atmosphere drastically. AEROFILTER, THE FUME TREATMENT SYSTEM MARINI has developed and installed AeroFILTER,...

This project provides a new system that ensures significant energy savings during production and plant operation. It also reduces pollutant emissions into the environment when producing mixtures with bitumen binders. HIGH-EFFICIENCY RAP HOPPERS MARINI PATENT

MASTER TOWER TECHNOLOGY The MASTER TOWER technology includes 2 dryers on the upper side of the mixing tower. This position helps minimise packing problems related to RAP (Reclaimed Asphalt Pavement) heating. RAP exits the dryer at 160 °C. This allows for asphalt production with high RAP percentages (up to 100%) without overheating virgin aggregates. This way, we can save energy while preserving the quality of the residual bitumen. REDUCED HEAT LOSS Virgin aggregates reach the mixing tower screen from the dryer’s discharge chute. This way, it prevents heat loss from occurring in traditional plants’...

ASSEMBLY, MAINTENANCE, AND SAFETY Plants designed for operators ASSEMBLY: all modules are pre-assembled at the factory to save time and prevent problems at the job site MAINTENANCE AND SAFETY: we create plants keeping the safety of your personnel in mind. Moreover, we strive to ensure safety by preventing accidents and unpleasant situations

The plant's innovative design allows the use of all types of additives. An optional kit can be integrated into the plant at any time to use cellulose fibres, pigments, and polymers to modify the bitumen (wax, EVA, SBS, Latex), transparent bitumen, rubber powder, and anti-stripping agents. Usually, WMA is produced at a temperature lower than 30 °C compared to HMA. However, like HMA, it ensures high performance. The energy saved by producing WMA is possible with an easy installation. o pressurised water dosing unit o a foaming ramp for water injection in the bitumen supply pipe o software integration...
