Any information on material - size moisture, wet or dry screen and possibly installation drawings?

Come, come gentlemen. Where have you put your crystal ball ■
Re: Screen Feeding Challenge
A lot more information is required but some general ideas;
> The ore will spread out on the head drum of the 1600mm belt such that it will flow over 2000mm in width at the impact point onto the screen providing you do not use a deflector or any similar flow control device. This spreading off the pulley will increase once on the screen.
> Try to set the screen up such that there is forward momentum from the ore flow down the screen. This will improve the flow and material spread.
> If height and everything is against you maybe introduce some form of splitter into the material flow such that you improve the ore spread over the screen width

Double Or Quit
Not so long ago a very smart young contributor suggested using 2 infeeds. Its the best idea I've come across.
Have you seen the price of crystal balls these days?■

Ziggy Gregory,
Some more available details are
1. Lump size - (-)300 mm - 61%, (-) 500 mm - 14%, (-) 750 mm - 20%, (-) 1000 mm - 5%.
2. Moisture - 4 to 5%.
3. Screen - Scalping screen.
Building drawing is being developed now only, but because of layout constraint the height of the building is restricted.

designer,
Thanks! for the reply.
What is this crystal ball? can you provide some details about this?

louispanjang,
Thanks! for the reply.
Do you mean to provide a two way chute in the screen inlet.

Screen Feeding
Looks like you are placing a scalping screen ahead of a crusher. The ore seems to be ROM. It is new plant still under design stage. I am unable to understand space constraints.
- 1000 mm boulders are being handled on a 1600 mm wide belt. Is it s belt or apron feeder? ■

With such a size distribution, you should not have too much trouble. Why not a sideways oscillating table on the infeed? You could also go for chevron bars on the screen itself to help spread it.
As a matter of interest, what size are you trying to pass through the screen? ■
Screen Feeding Challenge
(-)100 mm is the size that we are trying to pass through the screen.

Re: Screen Feeding Challenge
Hello there..
I don't know what all the fuss is about.. (Crystal balls? what a lot of..........)
To feed the screen you will need a dead box in the trajectory of the flow of iron ore from the discharge pulley so as to back-feed onto the screen.
Make the dead box about 2 to 2.5m wide and its discharge must be low and onto the impact section of the top of the screen.
By the time the iron ore is flowing down over the aperture section of the screen, it will be full width.
Good luck

Dear Experts,
In one of the project for 2000 TPH Ironore, 3000mm wide screen needs to be fed from a 1600mm wide belt.Additional height for introducing any feeder is not available in the building.Can you please suggest some good method to feed the screen without affecting the screen efficiency.
