Below address include a table which shows the relation with max speed and belt width and type of material

http://www.ckit.co.za/secure/conveyo...op-belting.htm

However it is mentioned that these values should be checked practically

And it has effected by slop ■

....Don't run with it before you can walk with it.

You can easily find this figure from the many handbooks and codes of practice which are available aplenty.

Most belt manufacturers provide the information in their design manuals. You can also find case histories within these forums.

Despite what others might tell you it is not advisable to exceed those figures. Some might tell you to run 2ms^-1 faster: some will say go slower. But they wouldn't know enough about your operating conditions to be able to say. For starters, handling capacity is 2000th^-1 with a bottom limit of empty. In terms of temperature: how freshly burnt is this stuff going to be? ■

"I don't like to follow this low speed. Low Speed belt means high tension belt."

Firstly, if your material is obscure enough not to be included generally then perhaps it is not so special and probably hiding under another more popular name. Alternatively perhaps a better description of the material would be appropriate. This assumes that the material actually already exists.

Secondly, Rulmeca seriously know what they're about. If their handbook says v=v then v it should be. Speed should be left to Honda. You seem to intend to run the conveyor faster to save on belt. This opens up a whole can of worms viz., shorter roller life; increased downtime; potential belt damage and the loss of most of your warranty protection.

Do what the literature advises or, more to the point, specifies. It's not your money you're spending. Your civil, structural and erection cost will swallow any saving you will make on a GT version. ■

Regarding to CKIT website the maximum speed for grain or free flowing material is 4m/s for belt width 1050mm.

As the iron ore pellet is free flowing maybe the above limitation can be used.

Is there any person who has experienced belt conveyor with 4m/s speed for iron ore pellet(burned)?

Yes, in Rotterdam at EMO terminal we run our conveyorbelts at 4.5 m/sec and we have only steelcord belts.

Our belt length is from 22 meters upto 1600 meters.

No problems with pellets

below post maybe useful

However I couldn't find there the allowable speed according to slop.

Polleke would you please give more information such as belt width and slop and capacity. ■

Our belts are 1600 and 1800 mm wide, the 22 m belt is 2400 mm wide

Our capacity is 5000 t/h

What do you mean with slob?

Probably: Slope>slop>slob.

Mohandes very recently brought an important proof reading oversight to our attention in another thread: concerning airflow calculation standards. It just proves the fragility of an otherwise admirable language graciously bestowed on the world by a more than grateful nation.

By the way, we still haven't got a precise indication of what Burned Iron Ore Pellet might be so it might be necessary to check the allowable speed practically: if it isn't too late or even if it is possible. ■

Sorry for my mistake in writing.

I mean slope of belt conveyor which I have seen in texts that effect on speed limitation.

Meanwhile you didn't have any experience with belt width=1000mm for iron ore pellet? ■

Depends on the GA drawings of the conveyor,if the slope is not too big, above 4.5m/s speed would be possible!
