Accessories for the Powder Flow Analyser

The following accessories are available for attachment to the Powder Flow Analyser to extend your powder property measurement options:

Vessels, rotors and blade accessories for the Poweder Flow Analyser

Test Vessels

Vessels hold the required volume of powder/granule material to enable powder flow measurements to be performed.

Precision tube in borosilicate glass with removable acetal base attachment ring to enable easy cleaning.

Vertical alignment and radial tolerance better than ± 0.05mm. Special materials and sizes on request.

Vessels are supplied individually or in sets of 3 and are available in 2 sizes:

• Typical sample volume 100-200ml: 50mm internal diameter / 130mm total height
• Typical sample volume 20-35ml: 255mm internal diameter / 80mm total height


Rotors provide controlled powder flow via patented precision blade action and enable measurement of caking, cohesion and powder flow speed dependence.

Shafts: 6mm diameter 316 Stainless Steel

Blades: 48mm diameter and 10mm height. Precision machined to optimise blade form. Over Anodised (Clear) Aluminium Alloy or 316 Stainless Steel as standard. Special materials and sizes on request.
