Portable fragmentation analysis


PortaMetrics™ is a handheld particle size analysis solution that uses AI and 3D imaging to eliminate the need for a reference scaling object.


“With the use of PortaMetrics™, we were able to analyze the fragmentation coming from our blasts, make improvements in the drilling & blasting process and achieve the quality parameters required by the processing plant.”
Mine Manager
Kleber Silva Gonçalves

“Using PortaMetrics™, we perform daily fragmentation analysis on stock piles, crusher piles, and at the plant, as well as on gravel that produces stoppage in the production wells.”
Christian Aliaga, Enaex Technical Representative
Los Pelambres Mine

Optimize Blasting Results

Efficient blasting is an integral part of any mining operation. Over-blasting results in excessive energy consumption and high explosives expenses, while under-blasting produces large rocks that overwork downstream equipment and shorten their lifespan. With an effective particle size analysis solution in place, mines can optimize blasting results and realized significant time and cost savings.

This powerful tool provides needed feedback to blast engineers, enabling them not only to validate the accuracy of their blast simulations but also to provide a good indication of digability.


3D Imaging

With three high resolution cameras compiled into a rugged industrial package and complete with a glove friendly touch screen, PortaMetrics™ is capable of capturing and processing images in any mining environment. Users can easily select their region of interest, capture an image and display results instantly on an intuitive graphical user interface. This point and shoot device includes manual correction capabilities to fine-tune images and make adjustments if necessary.


No Scaling Objects Required

PortaMetrics™ moves safety to the forefront of operations by accurately measuring particle size from a distance. Mine personnel no longer need to approach the bench face or climb it to place a scaling object.

Valuable Reports

PortaMetrics™ instantly generates reports to include rock size distribution graphs, size range statistics, slope measurements and more. Integrated GPS associates captured images with specific blasts, while cloud connectivity enables mine personnel to share results remotely. With all of these features available at your fingertips, mine personnel no longer need to return to the office and upload images to computer software to get accurate particle size distributions.


Underground Applications

Following successful trials, PortaMetrics™ is now available for underground applications. When paired with additional portable lighting, the device can accurately provide instant particle size results. With this information, important decisions can be made when sending blasted material to downstream equipment. By optimizing particle size, wear and tear on downstream crushers and conveyor belts caused by overworking is minimized.


Stay Connected from Anywhere

MetricsManager™ Pro is a web-based data analysis platform that enables authorized mine personal to access PortaMetrics™ data and generate reports from multiple images. Each report contains a particle size distribution graph, p-values with associated rock sizes, as well as accurate slop and range measurements – and, with date and time stamps, each image can be associated with a specific blast.
With MetricsManager™ Pro, drilling and blasting engineers can analyze valuable particle size data from any blast quickly and easily.


What is the min/max distance?

PortaMetrics™ provides accurate results between 0.5-30m.

Does it provide a count of how many rocks are each size?

The device provides a graph of rock size distributions – how many of each

Does it save data/reports/logs?


How long does the process take?

The device takes approximately 5 seconds to process the image and provide fragmentation results.
