Screen Bowl vs. Pusher Centrifuges

We ran several different sizes for the solid bowl (pusher) Birds for many years. Typically were pushing 30-40,000 pounds per hour dry basis through each at 21-24 percent water in the wet cake.

The issues were maintaining the planetary gearbox and maintain the watching the torque between the scroll and the bowl. Is you haven't looked at these there is quite a lot of thrust and heat generated from the scroll pushing the solids "up the beach" or into the narrow end of the bowl.

We ended up going from one to two and finally to three helix's or leads in the scroll. Also did quite a bit of work changing the ratios of the scroll to bowl speed. I Liked them better than the screens and thought I had much better product recovery. Your application may not require better recovery, or the dry wet cake.

Rates and performance did depend on the morphology of the product and, end result desired as well as the water in the incoming product.

We also found some of the wetting agents helped with water removal were not cost justified.

We searched the would for parts years ago. Do you have a good source?

Reply if you have detailed questions.
