Hi All

I am faced with the design of a pipeline to transport a sluury between two plants 80m apart, discharge 26m up.

partical size is upto 4mm (-4mm)

Volume 1300M^3/H @ SG 1.38

this equates to 650T/H

I have opted to use rubber mining hose for the aplication and need some advice on the routing.

One suggestion is to pump verticaly up first and then to slope the horizontal section sothat if the pump cuts the slurry will drain out of the horizontal section and it would be easier to clean the vertical section. This however poses a problem to construct.

option two is to have a gentle riasing pipeline and then a vertical up section at the end. this would be easier to construct.

any suggestions will be welcome.

What is angle of repose for slurry in pipeline?

You have specified a certain input parameter like 1300M^3/H @ SG 1.38

Kindly tell me what is SG stands for and whether flow1300 is flow of slurry or material to be conveyed.

In my knowledge we had installed the HCSD system in BALO , there was the same design you firstly opt for. Length was 2km . Whole concept is to inch the material vertical then slope it for a while distance . I dont know how technically it is right but could give the resonance touch what you have opted

Angle of inclination of pipeline should be less than the angle of repose. In our Laboratory, a pipe of 6.25 cm diameter and 1 meter length is used to determine the angle of repose of slurry. The pipe is filled with water and solids at concentration to be used in slurry pipeline and then fixed at different angles. Angle of repose of slurry is the angle at which the down-end of pipeline is just choked fully with particles. You can safely incline your pipeline upto angle of repose for slurry. I can suggest you the best configuration in your case if u tell me the angle of repose of slurry.

Hi

Thank you for your responses so fsr

Unfortunately I do not have the angle of repose. I do find it strange that you surgest that the incline should be less than the angle of repose.

I would have thought that the object would be to be higher so that if the pump trips it can drain, To the discharge and back through the pump.

the problem comes in if the slurry solidifies in the pump and you sit with the task to clean the pipe before one can start production again?

I meant to say that pipe inclination should be small enough to ensure trouble free pump start up. Settling solids should not slide down and block the lower end. If u keep the inclination less than angle of repose, after pump shutdown the solids will settle at pipe bottom in such a way that the entire pipe length will have some water in upper half of pipe cross-section. This water will later on help in trouble free pump start up. By doing so, some water will always be there in pump situated at down-end to avoid solidification of particles.

You say that Rubber pipe is your choice of pipe materials. Using this in an inclined system will give you a serious head loss on your pumping.

You need an internal bore which has a good co efficient of friction value such as a ceramic.

Please send to us your contact details and we can specify what you need along with pumping data.
