I am in the process of desgining a Iodization plant.Our product has a bulk density of 0.9gm/cc .I need to calulate volume flow rates from hopper to Interface hopper with screw feeder.

I need the formula to calculate the above .

Secondly for a given pitch of 220mm with the screw of dia 250mm & with a screw length of 2900 mm, i need to calculate the output for a material of bulk density 0.9gm/cc.This is right hand screw with a inclined slope of 15degress.

Regards Vijay ■
