Want to Change Water Cooled bearing to Non-Water cooled - Extreme duty and heat
Want to Change Water Cooled bearing to Non-Water cooled - Extreme duty and heat
(OP)
Hello To all, We are a Plastic recycler that uses a large mechanical dryer to dry our plastics. This dryer had an approximately 78in horizontal shaft with metal fingers extending from it and the shaft spins at 1750 rpm. Weight of shaft is approx. 2000lbs. The fingers of the shaft basically catch the plastic and fling it to remove excess water.
Currently the dryer has bearings that are water cooled, but it is generating too much water excess that we then have to pump out due to Environmental regulations. I want to go with a a different type of bearing that does not require water. We recently purchased a second dryer that is a bit smaller for a second process line and it does not have the water cooled bearing. Any suggestions????

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Housing surface temp, process temp, and if possible the shaft temp near the bearings.
From your description and picture it is not clear to me how the bearing cooling water is managed.
Is the bearing cooling water dumped in along with the water flung off the plastic?
