Re: Copper Concentrate Hopper Design
Have a look at other successfully operational designs.
Depends, how do you propose to modulate the discharge and does the receiving item, require a reasonably consistent flow (onto a belt conveyor maybe etc).
TUNRA can test your material for a cost and tell you exactly (perse). Considering the implications of getting it less then optimum design this would seem to be a worthy investment.
And then the question is, is the apron feeder the most appropriate method of extraction – what about a belt feeder, screw feeder etc.

Re: Copper Concentrate Hopper Design
Thanks for your reply Lyle
We ARE planning to visit existing installations but they are far away in distance and time!
As this product is being sent to a ship loader it needs to be at a reasonably constant rate. We are aware of some installations that use a belt feeder and one that doesn't. Unfortunately the product is not in existance yet, the mine has yet to produce, so we cannot do a lab test etc. We have to rely on accepted practise, at this stage.
Thanks for the idea of alternative feeders.

Re: Copper Concentrate Hopper Design
We have worked on a number of copper concentrate feed and transfer systems.
Points of observation:
1. Do not install sharp valley angles - generous radii are better
2. Polish metal surface to near mirror finish 63 RMS or better
3. Do not use UHMW or its derivatives
4. Hi-chrome is best when polished
5. Very fine sub-micro particles tend build in corners with discontinuities
6. Polish in direction of flow - not across direction of flow
7. We prefer 75-80 degree slope angle with no corners. This requires special fabrication techniques.
8. We apply shape to liner material more so than hopper bottom ■
Re: Copper Concentrate Hopper Design
Certainly not an apron feeder. This is fine concentrate and low tonnage.
Belt feeder or vibrating feeder. We prefer belt feeder. ■
Re: Copper Concentrate Hopper Design
Nordell, thanks for your detailed reply
that is just the sort of information that we need. From what you say I asume that a feeder of some sort is usually put in. The ones we have come across have a belt feeder.

Copper concentrate hopper design
Good day colleagues
I am hoping somebody can help me with design of a load-out hopper (approx 20m3) for 10% moisture copper cons.
My questions are:
(a) what wall slope and lining material should I specify; and part
(b): is a belt feeder necessary for a 1500tph installation?
Thanks in anticipation.
