Portable and Stationary Asphalt Plant Baghouse Options

The baghouse captures the dust that might otherwise be released into the atmosphere. In addition, the baghouse dust collector is considered the “lungs” of a plant. When the plant cannot breathe effectively, it negatively affects production. This is an essential part of asphalt plant operations, along with the dust control system employed upstream to help retain and return usable dust particles back into the drum mixer rather than putting them immediately into the exhaust airstream.

CWMF is proud to offer two baghouse technology options: pulse jet and reverse flow, with multiple sizes for portable, relocatable, and stationary designs.

Reverse Flow or Pulse Jet Technology

Every asphalt plant has its own unique set of specifications. That’s why we offer custom design and multiple options, including two different baghouse dust collector technologies. We’ll be there when the dust settles either way.

Dust-Eater® Reverse Flow Baghouse Features

Recycle the air with the Dust-Eater Reverse-Flow Baghouse. It’s perfect for high-capacity plants – the harder you run your plant, the better it performs! The unique system design provides a constant process airflow without the need of a compressor or pulse valves. Fewer moving parts means less maintenance and a bigger return on your investment.

With stationary and portable models and three sizes, the Dust-Eater® Reverse-Flow Baghouse boasts a smaller footprint and longer bag life.

Dust-Eater® Pulse Jet Baghouse Features

Our innovative pulse-valve manifold design eliminates problematic hoses and potential airflow leaks and prevents valve freeze-ups on cold operating days. It allows for easy maintenance of the valve diaphragm from outside the baghouse and removal of the jet tube when necessary. With smooth internal surfaces, sidewall louvers, and the industry’s largest inlet knockout, our baghouses reduce airspeed, eliminate turbulence, and minimize wear, prolonging the bag and component life. Sidewall louvers prevent bag abrasion and protect the first 10’ of the bag chamber.

Greater bag spacing allows dust-laden air to penetrate in and around the entire bag matrix, so inside bags work just as hard as outside ones. This generous spacing also minimizes the amount of pulsed dust that clings to the adjacent bags. Increased sidewall clearance facilitates even filtration of dirty air throughout the house. Integral venturi cages with snap-lock bags allow for easy installation all while providing an extremely positive seal between bag and tube sheet.

On our portable baghouse units, our unique false floor design minimizes the reintroduction of fines as the drag slats move them toward the discharge auger.
