The following is literally a guess, though the conveyor belt tracked off, then conveyor belt was jammed against structure etc, causing the conveyor belt to twist.

I guess the same, also because we found the conterweight pulley out of its guides.
Therefore the offtrack has been severe, with the counterweight pulley heavely "lean", and the consequent jamming against the structure caused the belt to twist like a "sock".
Conveyor is approx 50 mt long, 10° inclined. the only oddity that we found wad a big (huge) accumulation of carryback material in the return side, especially in the tail pulley. Tail section was practically full of material (gypsum, powder).
In your opinion, Could this resistance cause a "bouncing" of the counterweight, to the point that it came out of its guides?

The following is a literal guess, however I propose the tracking issue caused the countermass to leave the guides.
I am impressed the countermass relatively survived.

What do you mean with "I am impressed the countermass relatively survived."? That it did not fell off?
By the way, I am completely revamping the guiding system, which was made out of two opposed angle bars 2"x2".
I'm making several changes and overall moving to 4x4" angle bars with double lenght guiding pins.
I am also including in the desing two strands of chains with a certain slack to allow the vertical elongation of the belt (2%) but that will hold the countermass in position in case of complete tear of the belt

I intended that I was impressed that the countermass etc was not "destroyed" after apparently being loaded in an manner other than intended by the design.
The following may be considerations for the revamp, though may already be in control etc:
1. Confirm not over constrained to minimise jamming etc,
2. Appropriate aspect ratio to minimise jamming etc, and
3. Consider focusing on preventing the cause, instead of controls the event.

Twisted belt
Hi everybody, does anybody know what's happened here?
The belt has been running fine for more than one year without showing any oddity and nothing has been changed in the process, layout, material etc..., what could be the root cause of such a
twist??
