Olympus Pugmill Systems Leading the Way

Olympus pugmill systems are ruggedly constructed to perform dependably in harsh environments and mindfully engineered to reduce complexity. Integrated hopper bins, belt scale, and Danfoss controls provide precise dosing for mix design precision. Top-tier OEM components are reliable and readily sourced for improved field serviceability. 

Olympus continuous pugmill mixers use a twin-shaft design for continuous material mixing along the flight path. Mixing is done by twin horizontal shafts attached to mixing arms with paddle ends, which mix and move materials continuously. An electric motor drives the mixer, ensuring a steady flow of uniform mix from the discharge end. First, a bucket loader loads materials such as aggregates, sand, soil, and clay into cold feed bins. Based on the recipe, the operator sets the gate openings and belt speeds, which are electronically controlled from the control panel. Materials are conveyed on the collecting belt to the pugmill mixer. Liquids such as water and emulsions can be added and metered for precise dosing. Cement, lime, fly ash, and lightweight dry materials are added by connecting a vein feeder to a port atop the pugmill. The operator can adjust and monitor to control the mix designs.

    Olympus 3 Bin 200 TPH Portable Pugmill Plant

    Customer: New Jersey Site and Utility
    Application: Cement Treated Based with lime

    Joe Sanzaro – owner: “From the beginning, everything has been great. We ran 35,000 tons for the first job, got it over to the next job here, where we just did 35,000 tons, and we’re ready to do about 80,000 tons. It’s simple; there’s nothing much to it; just put the dirt in it and go! Everything has been great.”

    Olympus 3 bin systems are designed to facilitate mixing multiple materials. Site development contractors, such as NJ Site & Utility, add lime to the soil to enhance soil stability characteristics. The final product mixture undergoes inspection by a soil engineer before being used on building sites.

    OLYMPUS 2 Bin 200 TPH Portable Pugmill Plant

    Customer: Jennings County, Indiana
    Application: Asphalt production, cold mix used for road paving

    Jim Reeves – Highway Superintendent: “Maintenance real low, belts still in good shape, all around a good machine. I’ve got it set where it’s running 260 TPH. Saving tons of money. Before, we’d been buying our cold mix for $120/ton, and we could make it for $42 with labor, wear and tear, and everything figured in. Just grease it every time we run it, every tanker, very simple to run. It’s five years old, and it’s still running real good.”

    Since 2015, Jennings County, Indiana, has been using its Olympus pugmill to blend 1/2″ minus aggregate, 3% sand, and 5.5% AE-300 to produce cold mix asphalt, which is stockpiled and installed on approximately 90 miles of rural roadways each year. County superintendent Jim Reeves reports that they’ve saved several million dollars in their first five years by making their own cold-in-place asphalt mix using their own Olympus pugmill.
