Rotary Drum Agglomerators - FEECO International Inc.

Agglomeration drums work by tumbling material in a rotating drum in the presence of a binding agent. The binding agent causes the fines to become tacky and allows them to pick up additional fines, forming agglomerates in a process referred to as coalescence. The tumbling action helps to round the agglomerates and create a homogenous mixture.
