Single Pugmill Mixer

The Single Pugmill Mixer combines aggregate and liquid asphalt together utilizing stainless steel augers in a heated chamber.

The Mixer replicates in the lab how hot mix asphalt is manufactured at asphalt plants.

The chamber is capable of mixing up to 45lbs. Total coating of all aggregates is achieved in approximately 1 minute.

The chamber has a pneumatic gate (located at the bottom of the chamber) that allows a user to discharge finished mix into a receiver pan. A frequency drive allows a user to mix at multiple speeds. The Pugmill Mixer can be used for mixing soils.

The Pugmill Mixer also has an onboard Amp Meter whereby a user can perform short term aging of asphalt mixtures.
