A Review of Filter Press Basics and Issues
HISTORICAL PROBLEMS WITH FILTER PRESSES
- The cake has to be scraped manually out of the frames
- The frames cannot be too thin otherwise the feed ports block. This point applies to the plate and frame presses. For the rest, almost all filter presses now have recessed or chamber plates.
- If the plates are too large or there are too many of them, the weight is excessive.
