Wear Resistant Redux - Polleke's Chutes

Wear Resistant Redux - Polleke's Chutes

Wear Resistant Redux - Polleke's Chutes

(OP)
This query follows from the closed thread 342-130950 'Wear Resistant Material for Coal Chutes'

One reply may fit very closely to a problem facing me.  This is from Polleke(Mechanical), dated 4-Oct-05.  Your tonnage rates may be applicable if you could relate the gradation, or even the topsize of the iron ore you were loading.

I'm working on an ore pass system where the bottom leg drops through a grizzly into a 35-ft high bin.  The grizzly will have nominal 12-in by 12-in openings.  Does this sound similar to your application?

I want to line the bin, including a chisel outlet to an arc gate.  The tonnage rates (service lives) you noted from your tests have piqued my interest.  Your ore gradation would allow me to assess my own expectations.

Hope you catch this and can respond.  Thanks much.

RE: Wear Resistant Redux - Polleke's Chutes

Hello Backfill,

I work at a bulk trasfer company called EMO and we are situated in the Netherlands, near Rotterdam.
Yearly we unload about 14 million tons of iron ore and 20 million tons of coal.
Look at:
http//www.emo.nl
We handle coal and ore in size from: 0 mm up to 300 mm.
In special cases we are able to handle lumps up to 500 mm.
That is the size of the grizzly in our crane hoppers
The 300 mm is a safetynet under the hopperoutlet to protect the conveyorbelts from getting damaged by sump cover plates we dig outof the holds by our grabs.
In special cases and on request we remove the nets.

All the best

Harry (polleke)
