Fixed and Fluidised bed unit
Fixed and Fluidised bed unit
Specification
investigation of the transformation from fixed bed to fluidised bed
experiments with air and water next to each other
scales on the tanks to measure the height of the fluidised bed
water supply via storage tank with diaphragm pump
volumetric flow rate for air adjustable via valves
flow rate for water adjustable via speed on the diaphragm pump
measurement of pressure loss using electronic, hand-held unit

calculated by the integrated microcontroller
- An electronic display on the front panel shows flow rates and pressure drops for all three columns at the same time
- Comes with powerful data logging software
- Three cylindrical columns, one for water and two for air, each column with a diameter of approx.
50mm and height of approx. 550mm
- Complete with a demonstration of liquefaction and how the properties of liquefied particles change
with agitation
- Each column preferably have tapping points and differential pressure sensors
- Powered by universal power adapter with worldwide approvals
