 B&P
Pusher Centrifuges have amassed an impressive track record for reliability under all kinds
of service conditions. Our dependability is founded on sound design concepts, precise
engineering and top-grade materials. Here's an inside look at some of the notable design
features of the B&P Pusher Centrifuge:
- A single-piece wedge-slot screen captures solids.
- The screen is supported by a centrifugally cast, milled-slot cage basket.
- The cake is pushed by the reciprocating action of the pusher plate to which the feed
funnel is attached.
- The basket and pusher assemblies are attached to their respective shafts with precision
tapers to assure concentricity and balance of the rotating members.
- The main hollow shaft, which drives the basket, is carried by widely spaced, heavy-duty
bearings.
- The hydraulic pump is belt-driven by the main drive motor, eliminating a second motor.
- The pusher shaft is driven forward and backward by the internal, self-contained
hydraulic piston. The assembly requires no external controls.
- The rugged base of the pusher houses the hydraulic reservoir and provides a rigid
support for the entire rotating assembly.
- Cooling coils maintain hydraulic system temperature at optimum levels.
B&P’s proprietary wedge-slot screen design and construction enhances the
operational life of the entire machine.
- The screen is built of T-shaped bars that run the full length of the basket. The bars
are precisely spaced and rigidly anchored by circumferential rings. The construction
presents a smooth surface for the cake, minimizing sliding friction, abrasive wear and
product degradation.
- The open structure of the screen's outer diameter makes it easier to backwash and remove
crystalline products that precipitate out, ensuring maximum drainage of mother liquor.
- The single piece design screen requires no fitting together from multiple components and
will not lift or dislodge from the basket.
Obviously any machine with moving parts is subject to wear, but intelligent design can
limit the effects of wear. For instance, product abrasion will cause screen wear at the
pusher end of the screen. So we designed the screen so it can be pulled, turned end-to end
and re-installed to double it's service life. In other cases, we've designed the machines
so wear is concentrated largely on relatively inexpensive replaceable parts. |
