Granular Material Flow Analyzer.
The New Rheometer For Powder.
GranuDrum is an automated powder flow rheometer based on rotating drum technology.
A powder sample is analyzed while rotating in a transparent drum. Advanced image analysis tracks the powder/air interface and its fluctuations to quantify the Cohesive Index, Dynamic Angle of Repose, Aeration Index and Roughness Index. The Cohesive Index is a standard metric (ISO/ASTM TR 52952:2023 and ASTM D8648-25) used to predict and optimize powder flowability and process performance. Practical tests such as thixotropy, fluidization, settling, caking,
agglomeration, segregation and aeration are directly available in the software.
GranuDrum High Temperature (HT) is designed to analyze powder flowability and cohesion at temperatures up to 250°C, making it an essential tool for Additive Manufacturing and industries where manufacturing conditions differ significantly from ambient conditions.
This innovative device features an integrated heating system that pre-heats powders directly within the measurement cell, eliminating the need for external equipment and ensuring precise temperature control. With a rotating drum and high-resolution camera, the GranuDrum HT captures real-time fluctuations in powder behavior, allowing for accurate calculations of the Cohesive Index (CI) across varying temperatures.
By providing critical insights into how temperature affects powder characteristics, the GranuDrum HT empowers users to optimize material performance, enhance product quality, and make informed decisions in high-temperature applications.
