The Continuous Pugmill Mixer
The BHS Sonthofen LFK Continuous Mixer or Pugmill is a twin shaft mixer engineered in Germany. The mixing system works with two horizontal mixing shafts equipped with synchronized mixing arms with adjustable paddle tips. The paddle tips accelerate the aggregates being mixed and generate intensive relative movements which create a homogenous mixture in a short 8-10 second retention time.
How the Continuous Pugmill Differs from a Batch Mixer
In a batch mixer, all ingredients are charged into the mixer in a pre-defined sequence, and then mixed, discharged, and the charging process begins again. In a continuous mixer or pugmill, material is constantly entering and exiting the mixer. The materials must enter the mixer in the correct proportions. The mixing results in continuous mixers depend on metering accuracy and metering sequence of the incoming materials. Errors in the timing of the metering cannot be corrected by the mixer. If the aggregate enters the mixer before the water or cement starts flowing, the aggregate will leave the mixer just like it came in. Thompson Rock Mixers’ PLC controls and onsite startup assistance eliminate these errors.
Wide Range of Applications
The BHS LFK mixer has excellent resistance to wear, is easy to maintain, and has outstanding energy efficiency. It is ideal for mixing road base with water, Roller Compacted Concrete (RCC), Cement Treated Base (CTB), flex base, cold mix asphalt, and lime addition for asphalt plants.
