In the following list, you will notice that some of the characteristics may seem repetitive in different aspects (productivity, quality, cost or pollution), this is because they benefit in several aspects.

Wide bins to avoid Payloader aggregate spills on the other bins, avoiding aggregate contamination.
Accurate dosing thanks to precise motor speed control in the bins with minimum adjustments of just 1 RPM.
Material flow sensor located in the fine hopper with a low feeding alarm to avoid production without fine material.
Agitation of the asphalt in the tank by means of jet streams, this is to ensure homogeneity of the temperature and the suspension of the polymer for a longer time.
We also have the option of propeller agitators to further improve this important function.
Asphalt tank has automatic temperature control to keep it at an exact injection temperature, avoiding harmful variations in volume and viscosity.
Predetermined leg heights to guarantee the exact tome of permanence of the aggregates and the mixture of each section of the blades, whereby achieving an optimum quality.
The mixing drum is sealed to avoid cold air entry; the “Total Air” type burner does not require secondary cold air inlets, this means less air in the process minimizing asphalt oxidation.
A pre-heater before the burner burns 100% of the fuel, avoiding contamination of the mixture with unburned fuel residues.
To efficiently burn cheap fuels, it is necessary to preheat them beforehand to reduce their viscosity. Not preheating it causes it not to spray properly and many microdroplets may not burn.
With the advanced “Total Air” type burner with which all the air entering the drum is regulated by the burner, there’s no need for secondary air supply for combustion, this achieves a very efficient carburetion that takes 100% of the fuel.
Advanced “Variable Power” burner, on which the fuel is atomized at a constant pressure even with a power loss. By reducing its power and production rate, the fuel pressure remains constant; the atomization remains efficient therefore avoiding the formation of unburned microdroplets which will contaminate the mixture with unburned fuel.
The temperature is monitored in various parts of the drum, provided with alarms that indicate sudden changes, this is to minimize the oxidation of the asphalt and avoid aggregate calcination.
The drum is equipped with specific blade sections designed for each load phase, drying, heating and mixing, this will provide a better quality of the product.
  • Loading section: The blades are positioned to form a shield of material around the perimeter of the drum to prevent heat from escaping, whereby the material absorbs all the radiant heat from the flame. They are long enough to prevent the aggregate from falling into the flame, decreasing it; this would result in fuel losses and mixture impregnated with fuel.
  • Drying section: The drum has full sail blades for efficient heat exchange and rapid drying.
  • Heating section: The drum has full sail blades for efficient heat exchange and rapid heating.
  • Asphalt mixing section: The drum has blades of intense incorporation for a fast and homogenous mixing of the asphalt with the aggregates.
  • Fine reincorporation section: Composite sail blades reincorporate the fines that have been dragged by the air current into the mixture.
  • Homogenization section: Blade sets for total homogenization of the finished mixture.
  • Ejection section: The drum has a blade set for total ejection of the mixture; they are mixture recycling and segregation proof; then it’s transferred to the drag elevator.
In the backflow system, the asphalt is incorporated into the mix at a point where there are no more flames in the burner, so the asphalt never comes in contact with any flames or hot gases, thus, avoiding asphalt oxidation.
Minimum air velocity inside the drum so that the washer receives a minimum amount of fines in suspension, so that the loss of fines in the mixture is minimal.
Minimum air flow inside the drum allows a minimal quantity of suspended fine material to reach the washer, reducing the loss of fine material to a minimum.
The specific weight of the aggregates and humidity percentages are fed by computer: Transcendental factors for a high quality mixture.
Computerized control of the aggregate and asphalt dosing “recipes” to reach lab specs: Creation, storage, modification and application.
The dosing by volume is immune to weight variations due to the humidity content of the aggregates.
We also have the dosing by weight option for those who prefer it.
Computerized increment and decrement of production; with exact mixture proportions: dosage of aggregates and asphalt.
Computerized exhaust air gate with high precision electromechanical system and auto-correction to avoid overheating the mixture and decrease its oxidation process.
Computer assisted thermocouples calibration guarantees the accuracy of the computer’s adjustments based on its readings.
Minimum air flow inside the Baghouse, this will result in a uniform rhythm of dust precipitation, therefore a uniform return of the fine materials in the mixture.
Some international brands claim to have in their machines a uniform return of fine material in the mixture, which is not true. One of the reasons is that their Baghouse is not big enough and that makes the air gain speed, causing particle suspension and sudden collapses of great quantities of dust, this result in poor and irregular asphalt mixtures.
Configurable software for bag cleaning; this is so the fine material return of the mixture, the last step of this complicated process, be completely uniform, achieving a homogenous mixture.
Straight drag elevator, with low profile bucket at the end ensures an even delivery of the mix with minimum segregation.
Curved drag elevator, with low profile bucket ensures an even delivery of the mix with minimum segregation.
Complies with the most common international mixing quality standards in Mexico and can be adapted to any additional or international standards required by the customer.
The fine material return system of our conter flow model complies with all international standards.
