Our Products

To measure is to know. Find out more about our range of products and solutions by clicking on any of the sections below.

Truck Particle Size Measurement Solution: Protect your primary crusher

Truck Particle Size Measurement Solution

A working primary crusher is of key importance in the mining industry and is a vital link between the mine and plant. If rocks or other materials are oversized when entering the crusher, they can cause significant damage, which is costly to repair. The Stone Three Truck Particle Size Measurement Solution uses machine vision laser-based sensors to measure and monitor the particle size distribution of ore as it goes into the crusher, improving uptime, increasing efficiency, and providing actionable feedback, ultimately resulting in significant savings for your company.

Truck Payload Volumetric Measurement Solution: Prevent overloading and under-loading

Truck Payload Volumetric Measurement Solution

Overloading and underloading can present certain challenges to the haul trucks carrying materials between pit and plant – challenges that the Stone Three Truck Payload Volumetric Measurement Solution has been specifically designed to offset. With this machine vision system in place, your haul truck loads will be monitored via AI-augmented smart sensors, with overloading or underloading alerts sent to you in real time, allowing you to manage any potentially dangerous or costly issues before they escalate. The benefits? More productivity, more visibility, and more control of your precious cargo.

Milling Diagnostics and Analytics Solution: For productive and efficient grinding mills

Milling Diagnostics and Analytics Solution

Grinding mills are costly to run, so ensuring their ongoing efficiency and productivity is vitally important. Irregular feed size can lead to inefficient grinding and reduced throughput, which can ultimately cause damage, delays, and unforeseen expenses. With the Stone Three Milling Diagnostics and Analytics Solution, you’ll be able to use the machine vision system to continuously monitor your feed size distribution and detect oversized materials in time, improving your mill’s performance and uptime.

Belt Condition Monitoring Solution: Prolong the life of your belt

Belt Condition Monitoring Solution

Managing your key assets is vital to keeping costs down and maximising availability on site, particularly when it comes to conveyor belts. Stone Three’s Belt Condition Monitoring Solution identifies surface features on your conveyor belts, such as splices, tears, and edge deformations, while detecting belt drift, preventing dangerous, disruptive, and costly belt failures.

Crusher Diagnostics and Analytics Solution: Increase uptime, optimise control

Crusher Diagnostics and Analytics Solution

A healthy mineral extraction process relies on optimal crusher performance. Complications like improper gap settings, irregular feed size and unpredictable liner wear can compromise this objective. With Stone Three’s machine vision Crusher Diagnostics and Analytics Solution, you’ll be able to continuously monitor the feed and product size distribution in real-time, while improving your maintenance planning, increasing your crusher uptime, and optimising your crusher control.

Flotation Diagnostics and Analytics Solution: Froth and Pulp sensor solutions

Flotation Diagnostics and Analytics Solution

Looking for increased recovery and more accurate grade control with your froth flotation process? Our Flotation Diagnostics and Analytics Solution use a machine vision system to continuously monitor your key froth and pulp metrics, allowing for automatic detection of suboptimal froth states, measurement of mass pull per cell and estimation of grade and recovery, ultimately resulting in improved flotation circuit control overall.

Bubble Sizer: Improve froth stability

Bubble Sizer

Improve your froth stability and grade with our Bubble Sizer – a portable device used to acquire information on the size and distribution of the bubbles and Jg in flotation cells.

An Installer for the Bubble Sizer software can be downloaded here (zip file 58Mb).

Intelligent processes. Better performance.

The costs associated with heavy industries can be prohibitive. Operational costs and capital costs keep ballooning, while the risk of lost-time injuries and unplanned downtime is ever-present. Add in the expense of equipment failure as well as maintenance and energy costs, and it becomes clear just how pressure-driven the industry is by margins and revenue.

Given the exorbitant costs of building new plants, for most the only workable solution is for mining and other heavy industry companies to work with the assets they already have – to increase their productivity and efficiency to extract as much value as possible from their existing capacity.

This is where Stone Three comes in. We offer end-to-end digital solutions that help to increase yield and optimise processes through real-time analysis and instant problem-solving. Our products help to decrease unplanned downtime and maximise productivity, saving millions in the process.
