Sodium Sulphate Silo - Flow Problems

Posted in: , on 12. Mar. 2013 - 16:29

Hello all,

Sodium sulphate is a bulk raw material that gives us intermittent flow issues, especially in discharging from our silos. Any suggestions on what to check and what data to collect, and from there I hopefully can proceed?

Typical values of material received from our supplier:

BD = 1200 - 1600 g/L (average 1450 g/L)

Moisture content = 0.15 wt %

DFR = 50 ml/s

Mean particle diam = approx. 150 micron.

Any and all suggestions and advice on how to proceed are welcome.

Thanks ■

Sodium sulphate is hygroscopic in nature and it is not unusual for this material to cake in silo. There could be a number reasons for caking i.e. Silo geometry, silo outlet size, silo discharger, Ambient conditions, Day night temperature difference. etc etc.

Since it could be a number of reasons for caking you need to provide above mentioned information for a proper assessment. ■
