Stabilized Base Mixers

Eagle Iron Works offers a range of rugged, high-capacity continuous mixers for applications in many industries. They appear in cold-mix asphalt trains and hot-mix asphalt plants. They are used to prepare stabilized base materials for roads and highways. Eagle’s mixers may be used to mix reagents with contaminated earth in soil remediation projects. With small modifications, they even appear in power generation plants to pug neutralizing agents into flue gas desulfurization by-products.

Eagle’s Pug Mill Mixers have a sturdy box construction. They feature a rectangular feed inlet with optional hopper on top and a rectangular bottom discharge opening at the opposite end. Hinged inspection ports on the top of the machine open to expose the expanded metal personnel safety covers underneath.

Spray bars and a direct reading flow meter make it easy to control the product’s moisture content. The plumbing can be modified to accommodate bituminous emulsions or other viscous fluids.

The counter-rotating twin shafts have intermeshing paddles cast of abrasion resistant Ni-Hard, a chromium-nickel iron alloy. The shafts are synchronized and supported at one end by a single-input, double-output speed reducer of Eagle Iron Works’ design. The shafts are supported at the other end by flange mounted, grease lubricated roller bearings.
