TOP TOWER “Long-lasting roads and energy saving are the primary concerns of road constructors today. The materials used must be recyclable, suitable for modern lowenergy formulas, and integrate the latest technical developments for producing low-cost asphalt. These principles are the foundation of our TOP TOWER, the complete range of state-of-the-art plants.

THE INNOVATIVE CONCEPT BEHIND TOP TOWERThe filter above the dryer drum allows for substantial savings in electricity and fuels.This plant helps reduce CO2 emissions considerably. A MAIN CHARACTERISTICS HIGH-PERFORMANCE BURNERS HEAT EXCHANGE OPTIMISATION OPTIMISED INSULATION ! CONSUMPTION CONTROL reduced heat loss thanks to the Top Tower configuration The electronic control and the compressed air-assisted spraying allow the burner to provide high efficiency • regardless of the operating conditions and fuel type (possible use with bio-oil, wood powder, hydrogen, etc.) the plant can be equipped...

SUSTAINABILITY Thermal protection EMISSIONS Emissions and odours are the most remarkable challenges asphalt production plants must take on nowadays. Emissions can be conveyed or fugitive. CONVEYED EMISSIONS: conveyed emissions result from the drying and mixing stages. They come from well-defined emission tables and have limit values that depend on the asphalt production technology DIFFUSE EMISSIONS: diffuse emissions are produced when materials are loaded and unloaded and during secondary plant operating stages. These emissions do not have a specific point of measurement but can be reduced by...

EVODRYER, THE FUME HEAT TREATMENT SYSTEM The new EvoDRYER system provides numerous benefits and ensures higher performance related to the use of RAP. It also thermally treats fumes that may contain VOC. RAP (Reclaimed Asphalt Pavement) is introduced in the dryer drum after the burner flame, preventing the bitumen in the RAP from deteriorating. Even odours and emissions are considerably reduced. The air conveyed by the mixing tower is fed behind the burner flame through an inlet at the front of the cylinder. This patented system distributes air to the outer periphery of the combustion chamber...

An essential step in plant management THE REASONS FOR MARINI’S CHOICE All over the world, the government authorities work to ensure the protection of the environment for a number of reasons: waste reduction resulting from the deterioration of the road network high amount of RAP with related storage problems reuse of raw materials: aggregates are lacking due to the decreasing number of active quarries on a national and international basis energy savings: consumption is lowered due to the reduction in aggregate quarrying, transport and traffic hold-ups bitumen recycling: because not just aggregates...

METERING SYSTEM THROUGH RECYCLING RING The recycling ring placed after the burner flame allows RAP (Reclaimed Asphalt Pavement) to be fed at the ideal point of the dryer drum without infiltration of parasitic cold air. RAP does not come in direct contact with the hot gases produced by the burner’s flame but is gradually heated in the drum by means of heat-recovery flights and mixed with the virgin aggregates previously heated up to a suitable temperature. Most importantly, this technology prevents bitumen from being damaged. 40 METERING SYSTEM IN THE MIXER RAP can be fed in the mixer through...

TRANSPORT, ASSEMBLY, MAINTENANCE, AND SAFETY Plants designed for operators TRANSPORT: TOP TOWER 2000, 2000 P, 2500 plants can be loaded in containers for quick, affordable and safe transport. Even more complex plants can be easily transported thanks to their modularity and the pre-wiring system ASSEMBLY: all modules are pre-assembled at the factory to save time and prevent problems at the assembly jobsite MAINTENANCE AND SAFETY: we create plants keeping the safety of your personnel in mind. Moreover, we strive to ensure safety to prevent accidents and unpleasant situations
