Methods for Evaluating the Quality of Iron Ore Pellets

Durability Testing Devices
Abrasiveness Index Testing Devices
Sieves for Measuring Dimensions and Classifying Pellets

Disadvantages of the Sieving (Screening) Method:

• Time-consuming method
• Inability to analyze the morphology of the iron ore pellets
• Pellet classification is the only possible output
• Low accuracy and lack of repeatability, especially with broken, irregular, or oval-shaped pellets
• Inability to easily change the sieve size; requires physical modification when needed
• Requires intensive manual operation

Pellet Size and Shape Analyzer (RATA Device)

This device calculates the size and shape distribution of different pellet types through image capturing using a line-scan camera during free-fall.

Definition of the Pellet Morphology Analyzer (PMA)

• Pellet morphology analysis is based on image processing

• Imaging via K4 line-scan camera during free fall of particles

• Capability to provide AI-based qualitative analyses in advanced versions

• Provides results comparable to sieve-based analysis

• Delivers graphical and statistical reports on pellet morphology analysis

Specifications of the Pellet Morphology Analyzer

• Very fast analysis

• High accuracy

• Provides geometric and morphological parameters of pellets with 50-micron resolution

• Possibility of achieving higher accuracy by selecting a suitable high-resolution camera

• Provides pellet classification results with customizable sieve size selection

• Usable for analyzing the morphology of polymer granules and other particles

Pellet Analysis Results and Reports

• Reports on geometric and morphological parameters such as: circularity, aspect ratio, concavity, compactness, etc.

• Access to statistical information of the calculated parameters

• Visualization of the morphology of each measured pellet

• Ability to process previously recorded images offline

• Access to stored images
