Class Information
Number: 494/55
Name: Imperforate bowl: centrifugal separators > Rotatable bowl > Including driven material-moving means therein > Rotatably driven coaxially with bowl, but differing as to direction or speed > Including plurality of discrete pushing or scraping elements moving proximate to material collecting surface of bowl
Description: Apparatus wherein the driven means includes two or more separate (i.e., noncontinuous), material-engaging elements (e.g., blades, plows), which elements force material from their path as they travel adjacent those portions of the member upon which the material tends to accumulate.
