Counterflow asphalt mix plant with RAP | Atlas Technologies

 What is recycling according to Wikipedia?

Wikipedia mentions recycling as a key component of modern waste reduction. It also states that recycling is a process where we change waste products into new products. This helps prevent the waste of useful materials.
There is clear evidence dating to as far as 400 BC state examples of recycling. Recycling provides so many advantages and savings over using new materials.

Why is recycling important?

By recycling, we extend the life and usefulness of a product that has already made to use. By recycling any product which is of no use can be converted to something which can be valuable and something which can be used again and again.
Recycling helps reduce the consumption of fresh raw materials, reducing energy usage, and helps in reducing pollution.

Recycling in the asphalt industry – some facts.
As we see the advantages of recycling and acceptance of the same in the asphalt industry have been wide. It is time before people start understanding the advantages of RAP with respect to our environment.

Recycling made possible by asphalt plants by Atlas:

It is a notable fact that when hot mix asphalt is recycled, the ingredients present like the aggregates and bitumen are as good as new. So it is very advantageous to use this material. This material is cost-effective, environmentally safe, and also as good as new.

Environmentally safe because we need not add any harmful chemicals or additives for processing RAP. Less energy is consumed in preparation here.

As good as new because the aggregates and bitumen present in a recycled asphalt pavement when reused with virgin material glues themselves with the new material and becomes a part of the new material.

Atlas has always made efforts to implement the addition of reclaimed asphalt pavement (RAP) material into its asphalt plants.

Our list of product includes:
Out of the above-mentioned products the products that can allow the addition of RAP are batch mix plant and counterflow drum mix plant.

Asphalt batch mix plant with RAP:

This equipment is considered to be the best technology as far as making hot mix asphalt is considered. It applies the most accurate technology and process to make HMA in batch. RAP is introduced directly into the mixing unit of the batch plant after weighing.

Counterflow asphalt plant with RAP:

Double drum plant:
We manufacture and offer counter-flow asphalt mixing plants for sale. These plants offer to dry and mixing in separate compartments. Both the compartments are drums which are equipped with flights inside and the rotation of the same helps inefficient heating and then mixing. The first drum is for heating the aggregates by use of counterflow technology. The aggregates enter the drum from one end of the drum and move towards the other end of the drum. The other end of the drum is equipped with a burner for heating the aggregates. As the aggregates exit the other end of the drum, their temperature is elevated making it ideal for mixing. As the aggregates enter the second drum, they get mixed with bitumen and filler material.

Single drum plant with mixer:

Instead of a double drum counterflow plant, customers can also opt for a single drum plant with a pug mill mixer for mixing. Such plants are commonly seen in Europe and they take up less space for installation. We have exported one such plant in Spain with the provision to add RAP directly in the mixing unit.
As you can see in the layout, these plants come with a drum featuring counter-flow technology for drying the aggregates, and for mixing the aggregates there is a mixer. The operations are the same as the double drum plant except that here we have a mixer for mixing instead of a drum.

Single drum plant:

In addition to the above types, we have recently developed a single drum type counterflow asphalt plant for addition to recycled asphalt pavement. Here the plant operation of drying and mixing is limited inside a single drum. The aggregates enter the elevated part of the drum and move towards the other end of the drum as the drum rotates. The aggregates inside the drum are treated to the burner flame in a counterflow manner. Here the burner flame starts from the center of the drum to the opposite end of the aggregates entry. This is different from the double drum plant where the burner flame starts from the other end of the drum. The aggregates are continuously moving towards the other end of the drum even after treated with the burner flame. Just behind the burner flame, there is a RAP collar on the drum which allows the addition of reclaimed asphalt pavement (RAP) in the drum. As the RAP enters the drum just behind the burner, it gets in contact with the hot aggregates. Since the temperature of the heated aggregates is already high, it helps to melt the binding material in the RAP and bind it with the virgin aggregates and binder material which enters the drum from behind the burner flame. When RAP enters the drum it is already being weighed and its flow is controlled as required from inside the control room.

This equipment is different from the other continuous asphalt mixing plants that offer the addition of RAP because it offers to dry and mixing in a single drum. This makes this equipment very compact and fuel-efficient.

How does this machine solve your problem?
This machine can be useful for you if your problem(s) are listed below:
  • Site space is limited.
  • You are always looking for fuel savings methods or tricks for your plant.
  • Want to shift sites frequently without getting into the hassles of setting the two drums or setting the mixing unit.
  • Recycling is important to you.

Advantages of Counterflow Asphalt Plant design are as below:

  • Less space required.
  • No hassles in the foundation as there is only one drum for both operations.
  • Minimum heat loss compared to a single drum with mixer and double drum plants.
  • Fewer dust emissions.
  • Add reclaimed asphalt pavement directly behind the burner flame at a point where the temperature of the aggregate is very good for mixing.
  • Saves fuel compared to other designs.
Conclusion: If your requirement is a counterflow plant with separate drying and mixing one or single drum counterflow asphalt mixer Atlas has it all Contact us to know more (click here).
