The G100 Hall flowmeter is designed and manufactured to GB/T 1482-2010. It is used to determine the flowability of metal powders (including cemented carbide powders) by the standard funnel method. It applies to powders that can flow freely through a standard funnel with an orifice of 2.5 mm or 5.0 mm.
Scope and principle
| Scope | Designed to GB/T 1482-2010. Used to determine the flowability of metal powders (including cemented carbide powders) by the standard funnel method. |
|---|---|
| Principle | Measure the time required for 50 g of metal powder to flow through a standard funnel. |
Apparatus
| Standard funnel (2.5 mm and 5.0 mm orifices) | Made of stainless steel (304), with sufficient wall thickness and hardness to resist deformation and excessive wear. |
|---|---|
| Stand and vibration-free base | Supports the funnel stably. |
| Balance (optional) | Sufficient capacity, readable to ±0.05 g. |
| Stopwatch | Readable to ±0.01 s. |
| Cylinder | 25 mL stainless steel (304) cylinder. The standard funnel method in GB/T 1479.1-2011 may also be used to measure the bulk density of metal powder. |
Test procedure
- Close the funnel outlet with a finger and place the sample in the funnel so that powder fills the bottom.
- Start the stopwatch when the orifice is opened; stop it when the funnel is empty.
- Record the time to 0.1 s.
