Batch v Continuous Centrifuges?
Following a request from a leading centrifuge OEM we have recently spent three weeks in USA undertaking trials at a leading polymer manufacturing facility.
The aim of the trials was to establish if the current batch process could be performed in a more continuous mode of centrifuge operation. Currently the separation element of the process is carried out using vertical batch basket filtration centrifuges. Whilst the batch type centrifuges perform well it is believed, if possible, that continuous centrifuges would be a more efficient approach.
It was considered that a Continuous Screen Bowl Decanter would be the preferred alternative centrifuge type. As a result a pilot size screen bowl decanter was installed for the purpose of the trials.
Having reviewed all the test data it has been decided by the client that continuous centrifugation would indeed be an improved alternative to the batch basket centrifuges. Discussions are now underway with the OEM and other vendors where it looks like a total of 4 units will be ordered for their two manufacturing facilities in the USA and Far East.
Final confirmation is expected in the next 6 months.
