Portable Asphalt Drum Mix Plant

Portable Drum Mix Unit Dries aggregate and coats it with asphalt cement to produce HMA. Major components are a drum, burner, exhaust fan, aggregate bins, aggregate feed system, and dust collection system. All are mounted on a single trailer frame. A tractor with a fifth wheel attachment will transport the unit.
The drum functions as a combination dryer and mixer. Steel spokes attach the drum to two steel tires. The tires ride on four motor-driven trunions that rotate the drum. The burner is mounted on the elevated end of the drum and produces hot gases to dry the aggregate. The exhaust fan at the other end of the drum pulls the hot gases through the drum.
