Idler Configuration For Multiple Feeding Points
Your solution seems complicated. Once you establish a trough configuration it is not good to change it. In the case of starting with narrow skirts on a picking type idler, the load will spread when the skirts end. The idea of the pinching the load to a narrowed configuration of 45 degrees trough with short center roll will not be good for wear and tear and energy consumption. Finally relaxing the load on a standard 35 degrees trough will havea negative effect on the surcharge angle moving the load closer to the belt edges. Finally getting to the 30 degrees trough for the rest of the conveying path will spread the load a bit more.
I suggest that you pick a troughing configuration and stay with it. The first loading point can use normal skirts, say at 2/3 belt width. The subsequent loading points must use flared through skirts that will not obstruct the fow through of the previous loading points. If the flaired skirts are a bit narrowed then the material will heap nicely on the flow from the previous loading points.

Re: Idler Configuration For Multiple Feeding Points
I may have missed it the issue, though it sounds like there may be a case for a bulking in hopper.
If you like, you could install a couple of loading stations on the conveyor (just impact idlers - potentially anywhere you wanted along the conveyor) and then have a hopper c/w skirts etc which moves as required (maybe: on the reclaimers rails, tires or it just sits on the ground / foundations etc).

Re: Idler Configuration For Multiple Feeding Points
Hi Lyle,
Yes we are looking at bulk in loader hopper/feeder. The issue is multiple feed points with no spillage - the reclaimer will be operating with the secoind reclaim system.
The reclaimer skews a bit under normal operations - hence, the belt is running offset a bit thru the reclaimer loading table - hence my idea.......using 2/3 skirts is not going to work that well when we have a bit of misalignment
I will post a piccy tomorrow
Thanks...James ■

Idler Configuration for Multiple Feeding Points
Skirt/Idler Configuration for Multiple Feeding Points on a Yard Conveyor Strand
Hi
We have a yard conveyor for a bridge reclaimer - 900mm wide, 30deg trouigh and 2m/sec for limestone/clay mix. Rate is 400-500tph, 1600kg/m3
We are looking at having extra load / feed points for wet weather operation - one each end/side of the reclaimer.
The issue is spillage free/reduced feed points for the reclaimer (riased loading table) and the last downstream feed point. The feed from the reclaimer is lumpy as reclaimer by scrpaer buckets.
Also, the reclaimer can skew in plan view...so the elevated loading table skews as well and the belt runs a bit off tracking thru the loading table...this make things interesting.
I have some thoughts
First load point - go for picking carry idler sets and narrow skirt width
Reclaimer - move to 45 deg trough with un equal rolls - narrow middle rolll...get a deeper bed.
Last load point - wider skirts, 35 deg trough, elevated skirts.
Has anyone else mastered this problem or have any suggestions
Thanks
