Holographic 3D radar for ballast

Reference number
Coordinator RocksRay Sweden AB
Funding from Vinnova SEK 100 000
Project duration November 2017 - February 2018
Status Completed

Purpose and goal

Our idea is based on using microwave radar technology to measure three-dimensions of the stones and determining the size distribution in the ballast, in real time at the stonecrusher. The purpose of the project has been to verify the market and the technical requirements that the radar need to meet. Our technology is interesting for process and quality control and we have now a good understanding of the requirement for different applications. Through the project, we have connected to end customers and partners who are interested in supporting our continued development of the system.

Expected results and effects

We have a clear picture of both the technical and pricing requirements imposed on the system to meet the needs of process control and quality control. A plan for continued development has been developed based on cooperation with interested end customers and partners that can support us in the continued development by contributing with test environments, equipment and validation of measurement data. We have been able to verify our hypothesis that real-time measurement with radar can streamline production and that it is likely to produce equipment that meets the price picture.

Planned approach and implementation

Initially we collected information through reports and standards from SGU, RISE, TRV and SIS. We have then visited end users in the field of rockery, thereby finding out how quality and process control goes on today and what demands there are on the system in terms of environmental requirements, accuracy, resolution and frequencies. We have also discussed with companies that develop crusher control systems, which clarified the need for the process management system. Finally, a plan for the next development stage has been developed including technology, financing and cooperation
