a universal powder flow tester for measuring powder flow properties and powder behavior. The FT4 was designed with one purpose in mind to characteristic the rheology of powders, or powder flow properties. This remains a primary function today, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder flow tester.

The FT4 employs unique technology for measuring the resistance of the powder to flow, whilst the powder is in motion. A precision ‘blade’ is rotated and moved downwards through the powder to establish a precise flow pattern. This causes many thousands of particles to interact, or flow relative to one another, and the resistance experienced by the blade represents the difficulty of this relative particle movement, or the bulk flow properties. Excellent reproducibility and sensitivity, this is achieved by moving the blade in a precise and reliable way. The advanced control systems of the FT4 accurately set the rotational and vertical speeds of the blade, which defines the Helix Angle and Tip Speed.

• The ability to simulate powder processing conditions, by testing samples in consolidated, moderately stressed, aerated or fluidis state
• The application of multi-faceted powder characteristic to assess dynamic powder flow, bulk and shear properties to construct the most comprehensive understanding of how a powder behaves
• Unparalleled sensitivity, enabling the differentiation of powders that other testers classify as identical
• Fully automated test programs and data analysis
• Conditioning mode provides unparalleled repeatability
• Range of sample size, 10ml to 160ml (in addition a 1ml Shear Cell is available) 

The FT4 is a truly universal powder flow tester, with four categories of methodologies, defined as Bulk, Dynamic Flow, Shear (in accordance with ASTM D7981) and Process.

• Bulk: Density, compressibility and permeability
• Dynamic Flow: basic Flowability, Aeration, Consolidation, Flow rate and specific energy
• Shear: Shear Cell and Wall friction
• Process:  Segregation, Attrition, caking, Electrostatics, Moisture and Agglomeration

Proven Applications

The FT4 has application in all powder processing industries, including pharmaceuticals, Fine Chemicals, Food, Cosmetics, Toners, Metals, Ceramics, Plastics, Powder Coatings, Cements and Additive Manufacturing. Applications extend to:
