Re: Pfister Feeder
Hello,
Light Springback materials such as Saw Dust , Agri Wastes , Tyre Chips need proper prefeeder extractor - irrespective of the source of feeder. ■
Re: Pfister Feeder
thanks for the reply - yes, already planned on that. I am looking for any feedback that might cause us to not consider a Pfister feeder. We are trying to evaluate enclosed weigh belts vs this type of feeder. I have some experience with weigh belts and know that they can be finicky animals in and of themselves. ■
Re: Pfister Feeder
Honestly - I am curious about the application. If the term "Pfister feeder " means a Rotor scale - I suggest to consider that the input cross section is rather small - and needs a standpipe to create sufficient pressure to fill in the blade cavities - for the usual applications like Pulv Coal , Kiln Feed , Fly Ash -- which I am familiar with . Light fibrous materials do not create much consolidation pressure unless sufficient height is available - hence wall friction can sustain arches - requiring large extraction areas . Maybe a trial run will be a good thing !
Also depending on the feed rate - the volumetric capacity may be an issue too ! ■
Re: Pfister Feeder
thanks for writing back...The application is to feed an engineered fuel to a lime kiln. The material is a blend of plastic, sawdust, resins, oils, inks, etc. It is about 25 to 32 pounds per cubic foot. The sawdust is the absorbent matrix. We expect to feed nominally 100 cubic ft per hour of the material, about 1.5 tons per hour. My boss is enamoured with Pfister feeders, ie, horizontal rotary feeder. To work with this material, it would have to be fluffed just prior to the feeder. I think a belt scale might be more user friendly, but you do what you are told. Currently, the system envisioned is to have two docks for walking floor trailers, which would feed to a star screen, which would pick out any big stuff, then move to the weigh system and finally into a blow through rotary feeder. The material has an angle of repose that is virtually vertical - it will bridge completely over if it packs. My thinking is that if we use a feeder like he wants it will have to be quite large.

Re: Pfister Feeder
The Redler Circular Bin Discharger has been used for years for a wide range of products including wood chips and sawdust to be fed to furnaces.

Engineered Fuel Feed System
Hello,
Excuse possibly uncalled for initiatives - but the scene is familiar . Looks the scheme is in an advanced stage - but - fortunately , it is in a reasonably proven line. However, from the description, it is unclear if the Pfister feeder is the weighing device or a horizontal starfeeder only preceeded by a belt weighfeeder . A blow thru rotary feeder with a large inlet will be safer .
Wud you like some org from EU with direct experience in several similar plants and having north american subsidiary to get in touch with you ? If yes, please email direct to me . ■
Re: Pfister Feeder
bkmandal - The Pfister feeder would be used as a weighing device - I will contact you later when things are a little further along...Designer, thanks - that is a piece of equipment I didn't know about ■
Clyde Rotofeed
Hello
I represent a company Called Clyde Materials Handling, we specilise in Pneumatic Conveying and Injection Technology with over 30 years exprerience.
We are currently working on many project for injecting SRF (Solid Recovered Fuel) which is very similar to yours.
Over all project is receiving unit, star feeder, storage silo, with sweeping extraction screw, then our rotoscrew injection systems.
We have many advantages over Pfister, as we have not pressure limits and are not limited on injection distance.
Please feel free to email me for futher details
rsagar@clydematerials.co.uk
We also own a company called MAC Equipment in the US, who are promoting our products, plus manufacturing locally, as well as our own subsidery Clyde Materials Handling Inc.
Best Regards

Re: Pfister Feeder
thanks for the info. I have used some Clyde equipment in the past - top notch stuff. I will get in touch with MAC and see if they can get some more information to me - I know a guy with them pretty well.

Pfister feeder
Anyone have any stories or advice to share about Pfister feeders either good or bad when used with a cohesive material like oily sawdust?
Any advice/comments would be greatly appreciated. ■
