This customer in Virginia had experienced severe problems with their CMI triple drum. Stansteel custom engineered a straight counterflow drum conversion. This conversion included modifying their existing long nose burner and providing a straight counterflow drum. In addition, the recycle collar was added to have extended mixing time in the section past the heat transfer in the counterflow dryer portion. The fuel-efficient combustion flighting was added to lower emissions and the unit was fit onto the same frame and trunnions.
In recent months, an Accu-Shear™ Warm Mix Multi-Function Additive Package System has been installed. The customer has used this very successfully on private, state and federal projects.
