Granutools products

The GranuPack is an advanced instrument designed to measure the tapped density and packing dynamics of granular materials with high precision. This automated system enhances traditional methods by providing detailed insights into the flowability and processability of powders through metrics such as the Hausner ratio and Carr index. It captures the micro-properties of powders—like particle size distribution, shape, and roughness—which are critical for optimizing storage, transportation, and processing. The GranuPack features an initialization tube to ensure consistency and precision during tests, using either 1mm or 3mm free fall taps. It employs an inductive sensor to automatically measure the sample's height, enabling real-time monitoring of packing dynamics. Additionally, the GranuPack High-Temperature variant can evaluate powder behavior up to 200°C, essential for applications involving heat processes like pre-sintering. Compatible across a broad spectrum of powders, the GranuPack is a vital tool for industries ranging from pharmaceuticals to advanced materials.

The GranuCharge is an advanced instrument designed for accurately measuring the electric charge that accumulates in granular materials during flow. This device addresses the complexities of the triboelectric effect, a phenomenon where electrical charges develop due to contact between solid powder particles and surfaces within various handling equipment such as mixers, silos, and conveyors. Utilizing a customized Faraday cup integrated with an electrometer, the GranuCharge enables precise measurements of charge density as powder flows through a specially-designed vibrating V-tube that enhances triboelectric mechanisms. The instrument's capacity to control parameters like air humidity through its GranuMidity integration ensures that the measurements are both precise and reproducible. This versatility makes it suitable for a broad spectrum of applications across industries like pharmaceuticals, manufacturing, and materials science.

The GranuCharge AL is a sophisticated electrostatic charge analyzer designed to measure the charge per mass of powder during flow in real-time. It employs the triboelectric effect, which is a charge exchange occurring at the contact between two solids, to analyze electrostatic charging. This compact, portable solution allows for seamless monitoring of electrostatic charges directly at the production line. The system is equipped with a load cell that facilitates immediate access to charge per mass data, enabling the evaluation of powder interactions with various materials under real process conditions. Its at-line capability allows for rapid testing and informed decision-making, optimizing material handling processes, reducing electrostatic-related issues, and enhancing process reliability without disrupting production. Utilizing a Faraday cup and electrometer arrangement, the GranuCharge AL affords precise, automated measurements of the electrostatic charges, providing high repeatability and minimal setup effort, making it ideal for applications in electrostatic troubleshooting, pharmaceutical manufacturing, and additive manufacturing.

GranuFlow is a sophisticated powder flow testing instrument designed to optimize the analysis of powder flow rates through apertures, adhering to USP 1174 and EP 2.9.36 standards. It represents a significant advancement over traditional Hall Flow Meters (ASTM B213, ISO4490) by incorporating an automated, user-friendly design. The device features a 500 mL stainless-steel silo, equipped with a rotating plate with seven adjustable holes ranging from 1 to 28 mm in diameter, customizable for diverse application needs. Its electronic balance automates mass flowrate measurements, streamlining the measurement process and reducing the need for manual intervention. The software assistance further enhances accuracy by providing advanced data analysis capabilities. By fitting the flow curve data to the Beverloo model, it calculates a flowability index and determines the minimum aperture size for flow, making it a powerful tool for assessing powder flowability across various industrial sectors.
