Chain Conveyor For Ammonium Nitrate
If integriti of product is important (powder formation not acceptable) chain conveyor is not a preferred solution.
Shaker type conyeyors using flat lignostone springs and box type trough is preferred solution. For vertical lifts a shaker type of screw conveyor can be used. This system hs an advantage of using hot air circulation in the box trough tokeep product dry and free-flowing.

Chain Conveyors
Chain conveyors are not suitable for powders. Please inform the conveying distance so that the correct solution can be provided. ■
Re: Ammonium Nitrate In Chain Conveyors
Isn't there something risky about hot air & shaking something which is a component of several commercial explosives?
I'd stick with the en-masse solution.
Elsewhere in these forums, a couple of months back, there was reported trouble with getting powder to climb a steep screw; even without the fluidising influence of hot air circulation and vibrations. ■

Re: Ammonium Nitrate In Chain Conveyors
A couple of comments :
The originator asked about PRILLS. Prills are not powder.
"Chain conveyors are not suitable for powders"
This is an erroneous statement that cannot go uncorrected!!
There are en-masse conveyors around the world happily handling powders. ■
Re: Ammonium Nitrate In Chain Conveyors
Indeed there are. ■

En-Mass Conveying
Regarding the utilization of chain conveyors for ammonia nitrate conveying, FMC does not recommend this. The bottom surface, and the sides are in continuous contact with stationary surfaces, this will lead to material degradation and the creation of fines which will adhere to the inner surfaces of the conveyor housings which can lead to potential hazardous conditions. We recommend slow speed belt conveyors, which can be totally enclosed, if desired. Any closed conveying system should be ventilated and exhausted.

"Regarding ... chain conveyors for ammonia nitrate conveying, ... The bottom surface, and the sides are in continuous contact with stationary surfaces, this will lead to material degradation and the creation of fines"
While true, the implied extent of resulting problems is overstated. ■
Re: Ammonium Nitrate In Chain Conveyors
Another ten bob's worth asks whether the contact is rolling or sliding? The very gentility of en-masse conveyors throughout food handling etc is their raison d'etre. Prills sounds like a tablet shape. If they can roll they might and that would reduce the degredation to what the customer expects. ■

Re: Ammonium Nitrate In Chain Conveyors
Prills in my experience are about 2mm dia. ■

Re: Ammonium Nitrate In Chain Conveyors
Prills are indeed little balls made by a droplet forming / drying process not unlike a spray dryer. Ammonium Notrate prills are very friable and like others who have posted I would be very nervous about using en-masse conveyors for this material. I'd strongly recommend sticking to a belt. Small amounts of dust in this material can be coped with relatively easily at the production site but (assuming it for fertilizer use not explosive grade?) when your customer farmers stand it in the corner of their barn / storage shed for a month or so don't expect them the dust has absorbed moisture and then redried to form one big lump.
This material isn't an explosive in its own right by the way, it is an oxidant, it only exploded if mixed with oil, grease or similar materials. Avoid anything which has the possibility getting oil or grease into the product. ■

Ammonium Nitrate in Chain Conveyors
We have a client considering the use of en-masse type chain conveyors for ammonium nitrate prills, because they are totally enclosed, dust free, gentle and slow speed - 0.25m/s.
Client wishes to find a plant using such conveyors for this material to discuss suitability and experiences etc - can anybody help please?..... ■
