If you are smoothly discharging bulk clinker from ships and the operation runs well at the area of hopper outlet/spout inlet, please could you advise me the hopper discharge outlet size and spout inlet size. I do not want to get a spout too small to be reliable, but ofcourse do not want an unnecessarly large spout diameter.
Altho i know the rules about grizzley sizing (our slots 250x300) i am anxious to hear from someone who has an acceptable clinker discharge operation running. this would then have allowance for un measurable hopper cleanout clumping, cargo rubbish, rain effected clinker clumping, wharfside unexpecteds.
THE BACKGROUND TO THIS QUESTION
We are supplying two hoppers and 3 grabs to discharge bulk cement-clinker ships.
Grabs discharge into wharf side hoppers 3.5 meters deep x 6 meters footprint (60Tonne).
Open vehicle trucks drive under hoppers.
Hoppers (not mass flow) gravity feed into the truck deck about 4 cubic meters per minute.
Dust control is important so we will be using skirted, dust controlled loading spouts.
From experience 700mm square hopper outlet gate is OK for the operation.
Standard available loading spout inlet size for this required loading rate is 350mm dia
I know that generally 700mm hopper outlet does work. I am concerned that the bulk clinker may hang up in the 14" spout inlet.
Hopper and Spout Discharge Size
Hi there,
I would value your advice on this matter:
