This company’s purpose-built perfluoroalkoxy (PFA)-coated ribbon blender (photo) is engineered to meet the needs of sensitive and challenging applications where stainless steel or carbon steel may not be suitable. The interior of the trough, the double ribbon agitator, bolted stub shafts and funnel of the valve are all durably coated with black PFA. In addition to preventing product contamination and corrosion, the PFA coating promotes material release and simplifies cleaning. The dust-tight knife gate valve is easy to operate and further ensures a smooth discharge process. Operator-friendly controls via a variable-frequency drive (VFD) with forward and reverse functions make the blender very convenient to use across a wide range of media, including powders, pellets and slurries. — Charles Ross & Son Co., Hauppauge, N.Y.
