Rotary Lock Paddle Cracking Issues
Rotary Lock Paddle Cracking Issues
(OP)
We have a few rotary locks that transmit PTA powder (similar to flour). Hard concrete like rocks form in the powder that get transmitted with the product. When this hits the rotary lock it puts a lot of stress on the paddles and cracks ensue. What are the best ways to support the blades? Cracks spread along the bottom through the side then the paddle breaks off. Plate running between the centers?

If not has the process changed, or parts now from a different supplier?
Do they bend before breaking? Would even be possible to tell?
I'm kind of lost without some pictures.
Welded construction?
Materials?
Poor geometry, even lurking in small features, or pre-cracked welds can murder an otherwise adequate design.

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.

Is that a nicely developed crack in a blade in the background?
