Inverting filter centrifuge

Multipurpose Applications. Cake thickness is varied, dependent upon the application. Thin cakes from finer particles or more amorphous, compressible materials versus thick cakes for hard, easy filling crystals. 

By operating with minimal vibration, wear of mechanical parts is reduced. Bearings and shaft seals are changed on a preventive maintenance basis every three to four years. 

Regular maintenance is required for the filtercloths and product contacted 0-rings. These must be chosen in materials of construction compatible with the product. They are usually changed at the end of a campaign before switching to a new product. For dedicated processes, lifetime will depend upon the product.

Inverting filter centrifuges come in bowl diameters ranging from 300 to 1300 mm and achieve g-forces of 3000 - 900 X gravity.

The trend towards elimination of hydraulics in pharmaceutical process areas has turned maintenance over to the instrumentation and electrical specialists, as variable frequency drives become the standard. The Inverting Filter Centrifuge (Heinkel) eliminates all hydraulics from the centrifuge design to satisfy increasingly stringent cleanroom requirements by pharmaceutical companies. The risk of hydraulic oil in the process area has been a concern with respect to contamination with the product. 

Out of balance conditions usually occur due to feeding of an unbalanced load or uneven cake. This is more likely in vertical basket centrifuges than horizontally mounted systems. It is less common in an Inverting Filter Centrifuge due to the central feed distribution.
