ASPHALT PRODUCTION FILTERS & BAGHOUSE MAINTENANCE

We at Albarrie are well aware of the limitations and specific needs of asphalt producers. In fact we are a major supplier of filter bags & baghouse maintenance services to this industry worldwide.

During the asphalt production process, filter media is exposed to severe environmental conditions and corrosive gases. Fluctuations in temperature, frequent start ups and shut downs, and the prominent potential for sparks, result in additional strain on filter media.

Albarrie’s experienced filtration specialists will carefully assess your specific applications to ensure that your production operation is running at optimum levels. Albarrie’s proven engineering capabilities enable us to design a fabric specific to your individual process and equipment.

We pride ourselves in making the best possible filter. Our experienced people, quality control program and in-house laboratory ensure that Albarrie’s products are second to none!

Aramid Filtration Media


Aramid fabrics have become the product of choice in a wide range of high temperature filtration processes. The thermal resistance offered by aramid fibers is a key property in protecting against sparks, a common concern in asphalt production.


Aramid,-5500

 

Fabrics made from aramid fibers can be used in applications where the operating temperature does not exceed 200°C (392°F). Aramid fibers possess good resistance to oxidizing agents; however they possess relatively poor resistance to acids – especially in high moisture applications.

Dryer Drum Seals for Asphalt Mixers


Albarrie’s innovative cost effective solution for standard dryer drum seal gaskets is taking the asphalt industry by storm!

 

ALSEAL restricts dryer drum air entry and heat escape. Unlike ordinary rubber gaskets, which require frequent replacement and are overly rigid, ALSEAL is custom fabricated to fit and operate on all dryer drum mixers from ambient temperatures up to 500°C (932°F).

 

In addition, unlike fragile rubber seals, ALSEAL does not become brittle or crystallized when exposed to heat or cold.  Many asphalt producers have achieved a 5-year service life! When compared to the service life of a year (or less) for typical rubber seals, the decision to change to ALSEAL makes cost saving sense.

High Efficiency Filter Bag Cleaning


Reduce maintenance costs by blowing new life into your filter bags.

 

Albarrie Environmental Services performs High Efficiency Cleaning (HEC), a filter bag cleaning service which we perform inside your baghouse. Our powerful and precise cleaning devices use a pressurized air impulse to release buildup and clean your existing filter bags while they remain in place. This can double the lifespan of your filter bags.

 

High Efficiency Cleaning provides the following benefits:

    • Saves the purchase and installation of new filter bags and baghouse cages
    • Reduces downtime compared to replacing your filter bags
    • Eliminates the labor costs required to change filter bags and cages
    • Reduces energy consumption
    • Increases permeability within your dust collection system
    • Reduces the pressure drop differential in your baghouse
    • Decreases particulate emissions

 

 

WATCH  THE PROCESS IN ACTION

Improve baghouse efficiency using Albarrie's Filter Bag Cleaning Services (HEC)

“We Lafarge, were preparing one of our portable baghouses for the summer season and had concerns of a coating of RAP (reclaimed asphalt pavement) on the filter bags. A used bag was removed and sent to Albarrie for testing. The bag had low “as received” flow values. New bags were being considered for the baghouse to have a trouble free production season. Albarrie explained their new HEC service to us and we decided to try it. They cleaned the filter bags, “Insitu” and brought the old bags back near to new flow values. The service took a day! We would consider using the HEC service during the season to overcome any upsets that may interfere with production.”

–Dave Henderson, Asphalt Sup’t.

Lafarge Construction

“In preparation for a stack emissions testing at two BMC asphalt plants, Albarrie was contacted for pricing on new bags. During conversation, Albarrie explained the HEC cleaning service. We at BMC decided to use the service rather than buy new bags. Resulting was a 50%+ savings, and service at both plants was completed in several hours. The bags were cleaned to new flow levels. Due to Albarrie’s cooperation with our schedule, we experienced no loss in production. Thus, when future problems arise, I will consider HEC cleaning service.”
