A North American mining systems integrator implemented a solution for a mining application company seeking a better way to identify particle size and increase awareness of jams on their mineral fragmentation conveyor line.
Mining Application Using IO-Link Master
Comtrol’s IO-Link Master 4-EIP, with the IO-Link laser distance sensor connected, helped them achieve both of these tasks. The main reasons they decided to use Comtrol’s IO-Link master were:
- Comtrol’s master is able to work directly with a PC, no PLC required
- Other IO-Link master solutions rely on a PLC to use and set up the master, which was not desired for this mining application
- The ease of set-up, powerful web interface and Modbus TCP support were other determining factors.
The end-user was using a vision system for analyzing mineral fragmentation on a conveyor line. The mineral would be broken down and sent along the line where the vision system would ensure the particle size was correct.
However, problems exist with picking up accurate readings when the bed depth, or amount of mineral on the line, is great. Working with Comtrol’s IO-Link Master that is used to connect the IO-Link distance sensor has helped the company increase their accuracy with reading the bed depth. The laser distance sensor is also used to pick up the distance to the top layer of mineral going down the line which helps normalize the data along with the vision system. This improves accuracy in analyzing mineral particle sizes as the line moves along.
