Asphalt Plants

High-temperature filter bags, filter cages, fans, and filter retrofit solutions for dust from dryers, screening, mixers, and flue gas lines. Dust load, operating temperature, maintenance access, and emission targets at each process point determine the right product selection.

Filter, fan, filter bag, filter cage and auxiliary equipment selection by process

In asphalt plants, dryer gas, hot aggregate dust, the screen/mixer area, and filler transfer generate high temperatures and wear. The baghouse, cyclone, ID fan, hot-gas expansion joint, filter bag/cage, and filler conveying system are selected together.

Process filtration, fan, and equipment scope for asphalt plants

Process-based system approach

The filter housing, fan, ductwork, filter element, pulse-jet system and discharge/conveying equipment are not independent of one another; they are evaluated as components of the same operating point.

Information clarified before quoting

  • Gas temperature: Normal/peak and low-load condition
  • Airflow: Drum capacity, false air, and moisture
  • Dust load: Filler amount depending on aggregate and fuel type
  • Fuel/gas: Fuel type, combustion quality, and acid/moisture
  • Filler conveying: Rotary valve/screw conveyor/elevator capacity

Product families we offer for asphalt plants

Asphalt baghouse

Filter system for high temperature and abrasion.

Aramid/P84/PTFE bags

Media selected according to temperature and gas chemistry.

Silicone coated cage

Cage compatible with high-temperature bags.

Cyclone pre-separator

How do we determine capacity and technical specifications?

Exact capacity is not set by a catalog name; it is determined by process flow rate, system pressure, temperature, material/dust behavior and discharge continuity.

Site risks

Issues we specifically check during quoting and site surveys

These are not success percentages; they are risks that must be verified on site to select the right filter, fan and auxiliary equipment.
