PSI® 1000 particle size analyzer

The PSI® 1000 particle size analyzer is designed for monitoring particle size distribution in various hydrometallurgical and chemical production, focusing on battery precursor materials. This system offers real-time analysis, allowing for immediate adjustments to maintain optimal production conditions.

Real-time process monitoring

Versatile sample handling

Continuous operation

Improved process stability

How it works?

The PSI 1000 takes samples from up to ten process streams, measuring slurry particle sizes ranging from 0.1 µm to 100 µm.
Slurry is pumped from a stirred reactor in a fast loop to the analyzer to provide trouble-free transport of the sample.
The 3-way sample valves of the analyzer turn the slurry flow direction to provide fully representative sample cuts of the slurry streams.
The system operates continuously 24 hours per day, with minimal manual maintenance needs.
The particle size analysis is based on laser diffraction.

Key features

Provides reliable reporting and analysis results in real-time for immediate process control.
Capable of taking samples from one to ten process streams, ensuring comprehensive monitoring.
Measures slurry particle sizes from 0.1 µm to 100 µm, covering a broad spectrum of particle sizes relevant for industrial applications.
Operates continuously 24 hours a day with minimal manual maintenance, ensuring uninterrupted process monitoring.
Air ejector for removal of the diluter unit ammonia vapors.

Advantages of laser diffraction

Laser diffraction offers precise and consistent particle size analysis without external calibration, suitable for various process conditions.
Most of the battery precursor producers use laser diffraction based laboratory instruments for product quality monitoring, thus laboratory results are comparable to PSI 1000 readings.

Importance of particle size analysis in precursor cathode active material (pCAM) production

The uniformity and particle size of the pCAM material critically impacts discharge and charging properties of the battery.
Particle size control is crucial for pCAM product quality.
Real-time particle size analysis helps to maintain consistency in product quality, preventing off-spec material and optimizing production efficiency.

Process monitoring and control

Operators can track parameters such as median particle size (D50), particle size span, and D10 and D90 sizes to control reactions effectively.
Automated process control based on analysis results enables rapid response to process changes, minimizing downtime and off-spec material.
Connectivity options for integration with plant automation systems and remote support capabilitites.
Seamless integration with Metso process optimizers and Geminex® digital twin.
Compatible with Metso Metrics services for performance reporting and monitoring.
