You should also include the hardness of the rubber bars in your inquiry as well IMO.

contacts in alphabetical order for conveyor questions

no specific order in this list.

Dunlop tire and rubber

Bridgestone tire and rubber

Goodyear tire and rubber

Yokohama tire and rubber company

Toyo tire and rubber company.

Kum Ho tire and rubber- from Korea- I hope that have that one right from memory

All the current conveyor manufacturers being JOY CCI, Krupp Robins, Long Airdox, to name but few.

WWW.ASTM.org materials testing

Any steel maker as they are members of industry trade groups and set many of their own standards for the products they smelt and form.

My many apologies if I missed others that are worthy of mention

Just below the impact area, we are removing the impact idlers frames out side. Removing the idlers. Fixing the impact bars by welding on those frames. Finally we are fixing back this assembly to take care of the impact load.

A few thoughts:

- breaking of idler assemblies can be caused by numerous reasons:

- DROPPING from too high onto the assemblies

- IMPACT idler centres could be too far c to c, move closer together

- think about install grizzly top above impact area if feasible

- slider beds can be put in by themselves or in conjunction with impact rollers

- if you need some spec, i would be happy to PDF something for you ■
