Battery Powder Compaction Density Measurement System
The Battery Powder Compaction Density Measurement System is a precision testing system designed to determine the tapped density and compaction behavior of powders under controlled tapping and environmental conditions. It provides accurate and repeatable measurements for battery electrode powders, pharmaceuticals, 3D printing powders, ceramics, and other fine particulate materials. The system supports automated protocols, high-resolution sensing, and compliance with global standards, enabling R&D, quality control, and process optimization.
Application
(1) Measurement of tapped density and compaction characteristics of lithium-ion, sodium-ion, and solid-state battery powders.
(2) Evaluation of pharmaceutical excipients and active pharmaceutical ingredients (APIs) for quality control and formulation studies.
(3) Testing of 3D printing powders, including metal, ceramic, and polymer powders, for additive manufacturing applications.
(4) Determination of powder properties for abrasives, catalysts, and food additives.
(5) Calculation of Hausner Ratio and Carr Index for flowability and packing behavior analysis.
(6) R&D and production-scale sample testing using variable cell volumes (1–500 cm³).
(7) Environmental testing under controlled temperature (-10°C to 80°C) and humidity (5–95% RH) conditions.
(8) Automated data acquisition and real-time plotting of tapped density vs. tap count for process optimization.
Standards
(1) ISO 3953 – Determination of tapped density of powders.
(2) ASTM B527 – Powder density measurement and compaction testing.
(3) CE/UL – Laboratory equipment safety compliance.
(4) USP <616> – Powder density testing methods for pharmaceuticals.
(5) 21 CFR Part 11 – Electronic records and data integrity compliance for FDA-regulated applications.
Features
(1) Dynamic tapping mechanism: Programmable tapping cycles (1–3000 taps) with adjustable amplitude (1–50 mm).
(2) High-resolution sensing: Laser-based volume detection with ±0.01 cm³ accuracy.
(3) One-touch automated workflow: Preset protocols for USP or custom sequences; automatic calculation of Hausner Ratio and Carr Index.
(4) Real-time curve generation: Density vs. tap count, pressure, and environmental condition monitoring.
(5) Material versatility: Suitable for battery electrodes, pharmaceuticals, 3D printing powders, abrasives, catalysts, and food additives.
(6) Environmental monitoring: Integrated temperature (-10°C to 80°C) and humidity (5–95% RH) sensors with automatic drift correction.
(7) Pressure control: Closed-loop hydraulic system applies up to 500 MPa with ±0.1% FS stability.
(8) Certified calibration: NIST-traceable density standards (1 g/cm³, 2.5 g/cm³) for accurate verification.
(9) Safety features: Overpressure protection, emergency stop, HEPA-filtered dust containment, and anti-static handling.
(10) Connectivity: Wi-Fi/Bluetooth for remote monitoring; compatible with LIMS systems.

Test Procedures
(1) Fill the powder sample into the designated density cell.
(2) Select the appropriate tapping protocol and set parameters such as tap number, amplitude, and speed.
(3) Start the test; the system automatically performs tapping while recording density, volume, and environmental parameters.
(4) Monitor real-time curves of density vs. tap count and review key metrics such as Hausner Ratio and Carr Index.
(5) Export test results for quality control, R&D, or regulatory documentation purposes.
Maintenance Information
(1) Inspect density cells, tapping mechanism, and sensors regularly for wear or contamination.
(2) Calibrate density measurement system periodically using certified reference standards.
(3) Keep the control system, touchscreen interface, and software environment clean and free from dust or moisture.
(4) Verify the functionality of safety interlocks, overpressure protection, and HEPA filters before testing.
(5) Lubricate moving components according to manufacturer recommendations to ensure smooth operation.
