When it comes to industrial mixing applications, FEECO manufactures the industry’s most reputable pugmill mixers, also referred to as paddle mixers. These continuous mixers feature heavy-duty construction, along with their U-type trough design, which makes them an excellent choice for agglomerating, mixing, or conditioning in demanding settings throughout a variety of industries. Pugmill mixers can be used as stand-alone agglomeration equipment, or as a mixing step in a larger agglomeration process utilizing a disc pelletizer or agglomeration drum.

Pugmills utilize dual counter-rotating shafts with pitched paddles to create a kneading and folding-over mixing action inside the trough. Material and binder (when applicable) are continuously fed into the mixer. The action of the pitched paddles moves material from the bottom of the trough, up the middle, and back down the sides to create an intimate mixture of materials during the predetermined retention time.

  • Mixing and Blending: FGD scrubber sludge, fly ash, and lime for SO2 neutralization, municipal sludge for composting facilities, pigments and dyes, and other processes combining moist and dry feed materials
  • Agglomeration and Dedusting: Granulation of agricultural chemicals, fertilizers, chemical consumer products, carbon powders, flue dust from dust collectors, animal feed
  • Material Conditioning: Fly ash, cement or lime kiln dust, foundry dust, iron-oxide, friction material waste, lead fume, zinc oxide, copper reverts and concentrates


Agglomeration offers a variety of benefits. Among them, agglomeration allows you to:

  • Reduce Volume
  • Stabilize Mixtures During Handling
  • Eliminate/Reduce Dust Problems
  • Control Hardness
  • Reduce Packing, Storage and Transport Costs
  • Improve Product Performance
  • Improve Handling
