now,

are some information is given: length is 160m with 50m vertical, 5 bends. and bulk density is 1500kg/m^3, if 75t/h material is need to be conveyed, how about the air flow , SLR, the pipe diameter.

but the client can provide compressor with 23m^3/min, so who can give me some information about conveying cement.

thank you

How about employing a consultant to solve your problem and learning from him ■

Dear kevinjcg,

The design you are now presenting is based on the client’s compressor of 23 m3/min and a 6”pipeline.

You indicate a 2 step pipeline without mentioning the diameter of the first section.

As the endvelocity is too high, I doubt that the begin diameter needs to be even smaller.

Therefore, I assume that the pipeline is 6” all the way.

In that case, the begin velocity will be 7.12 m/sec and the endvelocity will be 25.21 m/sec at a conveying pressure of 2.5 bar.

The SLR is then 36, resulting in 68 tons/hr.

Depending on the feeder system, the system capacity will be lower.

A two-kettle system with kettles of 7m3 volume and 5m3 cement content will have a system capacity of approx 58 tons/hr.

Back to the drawing board?

success

Dear kevinjcg,

I always used rubber seated, pneumatically actuated, butterfly valves in cement conveying.
