Sensor-based Sorting Equipment
TOMRA Sorting Solutions provides a complete product portfolio that facilitates extremely efficient material separation in various minerals and ore applications.
Four product lines are available supporting the specific needs of Run of Mine applications, Industrial Processing of Minerals, Diamond and Gemstone recovery and Metal Recovery from Slag. For each product line a number of sensors are available to support the specific separation task. Our products can be supplied with a width ranging from 600mm to 3000mm. We also offer many options and ‘add-ons’ that include different resolutions (depending on the size of the objects to be detected), valve block types and configurations. Please check the individual product sheet for further details or contact our team.
At TOMRA Sorting Solutions, we pride ourselves on producing simple to use and easy to install systems. Furthermore, they are low maintenance and a modem connection secures online system inspection and software downloads. TOMRA Sorting Solutions's systems Mean Time Between Failures (MTBF) stands at seven thousand hours. This means that our products will ensure your operation runs both highly smoothly and highly efficiently.
TOMRA Sorting Solutions sorting systems are integrated solutions consisting of:
- Detection system (EM, PM, COLOR, NIR, XRF, XRL, XRT, RM)
- Control system with local HMI and modem
- Valve block system including and air regulator(s)
- Vibratory feeder with electronic control
- Material handling and feed presentation system
- Accompanying documentation in various languages
Sorting with TOMRA Sorting Solutions means
- Innovative technology – selection of between numerous sensors
- High purity – up to 98 %
- High recovery – up to 100 %
- High precision – even the smallest of particles can be recognized
- High throughput performance – up to 400 metric tons per hour, depends on application and material
Our ROM Series sorting equipment is especially designed to meet the availability and robustness requirements of the real world Mining environment.
The PRO (Industrial Processing) Series sorting equipment is designed for the typical minerals processing environment.
The GEM Series consists of specialized equipment for diamonds and gem stone recovery.
Our SLAG Series sorting equipment is specialized in detection and recovery of smallest metal particles in a high tonnage slag feed.
The use of our machines in the various stages of the beneficiation process can make procedures significantly more efficient and markedly increase output. The overall energy, material and labor costs are reduced, while considerably more valuable minerals are separated from the waste material. The machines pay for themselves within a very short time.

High speed precision
The material running through the sorting process is heavy, dusty and abrasive. High demands on the technology on all fronts: Material handling, recognition and pressurized air ejection are combined by TOMRA Sorting Solutions in a robust and tested system which reliably separates valuable mineral ores from waste rock.
Regardless of whether diamond, gold, limestone or coal, the sensors recognize the target material on the basis of typical characteristics such as color, atomic density, transparency or conductivity. The range of different advanced recognition technologies by TOMRA Sorting Solutions offer the best suited sensor combination for any type of ore. The valuable mineral bearing rock is then selectively extracted using a precise pulse of pressurized air from the high performance nozzle system, regardless of whether it is a small diamond or a heavy lump of ore.
This technology provides top efficiency, precision and speed. Not even the smallest particle sizes evade this intelligent system, even though it works much faster than traditional sorting technologies.
