The powder analyser measures the flow characteristics of granules and powders in compliance with EP and ISO 4324 (12/83) standards.
This instrument tests powder flow time, measures the cone angle and weight of the collected powder mound and calculates the density and the volume of the powder mound as well as EP ‘flowability’ results. EP ‘flowability’ is a measurement of the flow time of a 100g powder sample through a specified pouring nozzle.
A conical funnel, which can be equipped with different pouring nozzles, receives the powder to be tested. The analytical balance is placed inside the instrument housing and holds the product collection dish. The electrical stirrer attached to the main instrument may be used for powders that do not flow due to a high percentage of fine.
This instrument is perfect for comparing batches of powders supplied by the same manufacturer over a period of time or for similar materials supplied by different manufacturers. The flow characteristics can be determined quickly and easily as a QC tool for inter-batch reproducibility, as this may have a distinct bearing on the ease of production, especially if powders are capable of agglomeration and cohesion over time.
Why are powder flow characteristics important?
- Reduction in cost of raw process materials: reject bad batches before processing
- Ensure powder quality and consistency from the same or different suppliers
- Maintain the optimum formulation for the process concerned
- Maintain the quality and consistency of the final product
- Investigate, maintain and verify the quality of dry mixes
- Develop new processes for powders set to be formulated into end products
- Confirm moisture effects: use of powders in open systems in different climates
