Scoping Slurry Pipeline Design

Hi,

I'm completing my thesis for final year of my undergraduate degree and am comparing a variety of ore haulage methods to trucking for a mine site.

I have reviewed literature on calculations for hydraulic hoisting of slurries but lack data on the ore /slurry to be handled as the site doesn't have this information available to me.

As a first pass scoping estimate I have used a basic formulae to calculate pressures for friction. The formula being:

P = R*Q^2 (where: P = pressure due to friction, R = Resistance and Q = quantity - SI units apply)

Can anyone comment on the reliability of this assumption; remembering that its only a "ball park" estimate is required?

Thanks in advance,

Lincoln Morris

There is/was/should be a link on this very forum page to the Warman pumps website. They are the business & will have pointers for your further study. Ball park figures are ludicrous for rheology which is a very complicated topic.

Dr Kashul ( I hope I've spelled it correctly) has some software & refreshingly useful terminology on the subject. He can be found through the forum.

Welcome to the world of "How to handle something which we haven't got because it hasn't even been produced. But the client is in a hurry!" It's called 'Bulk Handling'.

Cheers for the reply.

Its an interesting situation to be in that is for sure! But with a lack of any technical details on the ore to be transported I'm not exactly sure how else to attack the problem.

Thanks again,

Many studies comparing different modes of bulk solids transport are available in literature. Slurry pipelines are found to be economical for long distance transport.

For calculating the pressure drop in slurry pipeline, the knowledge of various properties of solids and slurry is essential. For details, you can read my research publications based on pressure drop in slurry pipeline available on following webpage:
