FEECO Pin Mixers

FEECO has been manufacturing high quality pin mixers for over 65 years. The pin mixer (also known as a pin agglomerator) offers greater material densification than a disc pelletizer, and typically requires less binder. Whether you are conditioning a material, de-dusting, or micro-pelletizing it, our custom pin mixers are a preferred choice.

 

Pin mixers are ideal for processing ultra-fine materials, and mixing both solid and liquid feedstock components to create a homogenous mixture.

 

Material is fed into the pin mixer, while binder is continuously added at a specified rate. The high-speed spinning action created by the single rotor shaft affixed with rods (pins) thoroughly mixes the components and begins to form agglomerates as the material moves through the length of the mixer.

 

Pin Mixers are ideal as stand alone agglomeration units, or as a method of pre-conditioning in a two step agglomeration process involving a disc pelletizer or agglomeration drum.
