Thread: High Wear in Slurry Transport

yzaydn,

even though your slurry is similar, even small changes in gradation and concentration can result in significant differences in recommended transport velocities that in turn require different pump and pipe sizes. can you provide us with the material gradation, and slurry properties with flow requirements?

we have used centrifugal pump to transfer slurry in 100 meter hose pipe line. However because of high amount of wear in pump and hose pipe, we worry if there is similar experience in other plants or not:
1-material: iron ore
2- solid percent: 43%
3-max. particle size: 6mm
4-pressure:7-8bar
5-flow: 430t/h solid+water 579 m3/h
6-changing impeller after 400 hours!
7-breaking hose pipe every week!

would you please inform me if you have similar experience and how we can solve the problem.

For the pipe line,we suggest to you use ceramic lined pipe,the ceramic material liner usually alumina ceramic which with a very high hardness level.http://www.fuvalve.com/56-ceramic-li...e-and-fittings

what sizes and types of pump and pipe are you using on this system? i ran some rough numbers based on the limited info you provided. please understand that slurry systems must be looked at as a whole when changing anything. changing any individual part affects all other parts of the system. those affects may be good or bad, so the entire system should be evaluated to determine if the change is beneficial and whether it should be adopted.
