Product Description
Powder Angle of Repose Testing Machine
The angle of repose is the angle (relative to the horizontal base) of the conical pile produced when a granular material is poured on to a horizontal surface. It is related to the density, surface area and coefficient of friction of the material concerned.
DF-1-05 repose angle tester is designed and produced based on ISO 4324:1997.

FAQs of Powder Angle of Repose Testing Machine:
Q: How does the Powder Angle of Repose Testing Machine measure powder flow and angle of repose?
A: The machine uses a standard, detachable funnel to pour powder into the stainless steel test chamber. Through variable-speed controls, the powder forms a pile whose angle is digitally measured with high precision, providing accurate and repeatable flow property data.
Q: What materials and specimen sizes can be tested with this equipment?
A: The machine accommodates powders with capacities ranging from 500 g to 2 kg and specimen sizes up to 100 mm, making it suitable for most laboratory-scale powder flow assessments.
Q: When is powder angle of repose testing conducted in the laboratory?
A: Angle of repose testing is typically performed during quality control, new material development, or when evaluating powder flow characteristics for process optimization or regulatory compliance.
Q: Where is this machine best utilized?
A: This equipment is designed for indoor laboratory environments requiring stable temperatures (10C40C) and humidity (10%90% RH, non-condensing). Its benchtop design is ideal for analytical and materials testing labs.
Q: What is the process for exporting data from the device?
A: After completing a test, data can be digitally exported to a PC or printer using the devices USB or RS232 interface. This facilitates efficient documentation and reporting of laboratory results.
Q: How do the safety features protect users during operation?
A: The machine includes overload protection and an emergency stop to immediately halt operation in the event of any issue, ensuring the operators safety and preventing equipment damage.
Q: What benefits do digital controls and displays provide for powder testing?
A: Digital/LED displays enable accurate, real-time readings, while digital export simplifies data management. These features enhance testing efficiency, reliability, and traceability in laboratory workflows.
