1. before we can tell you width x length, we need to know what opening in the wirecloth you are cutting at?

2. Wet or dry?

3. Metric tons per hr or Short tons per hour?

4. Free flowing material? I assume yes?

Can you please tell me why you have specified a Roller Screen?

If you can tell me the highlighted points below then I can tell you what type of screen, screening area and angle of screen is required.

Material - Iron Ore

TPH - 200tph

Bulk Density - t/m3

Material Size - (Is it 0-16mm)

Moisture - 7%

Separation required - (Is this 8mm)

Feed Grading - (i.e 100% passing 16mm, 50% passing 8mm, 30% passing 4mm)

I look forward to hearing from you, ■

We are going to apply roller screen as a tramp removing equipment over the HPGR in our iron ore processing plants

pls give me information about this screen for following situation (do you suggest this screen for iron ore?)

Material: iron ore (magnetite& hematite)

Particle size: <50 mm or <38 mm (tertiary crusher discharge)

Moisture content: <6%

Expected throughput: 700-1000 t/h

Circuit: closed (fresh feed with a banana screen circulating load)
