Paddle Mixers

CONTINUOUS PADDLE MIXERS

When it comes to industrial mixing applications, FEECO’s paddle mixers, also referred to as pugmill mixers, are ideal for tackling tough jobs. Their heavy-duty construction along with their U-type trough design makes them an excellent choice for agglomerating, mixing, or conditioning in demanding settings. Paddle mixers can be used as a stand-alone agglomeration device, or as a mixing step in a larger agglomeration process utilizing a disc pelletizer or agglomeration drum.

Paddle mixers utilize dual rotating shafts with pitched paddles to create a kneading and folding over motion 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.

FEATURES

• Double shaft design for thorough mixing of materials
• Heavy-duty construction for years of reliable operation
• Binder spray system to accommodate a liquid feed
• Options in paddle facings to help prevent wear
• Bottom doors open for cleanout
• Reversible paddles for modifying mixing pattern

PADDLE MIXER APPLICATIONS & MATERIALS

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

WHAT CAN AGGLOMERATION DO FOR YOUR MATERIAL?

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
