German Salt Mine – Safety + Energy Savings

A German salt mine is using the technology to protect workers and increase productivity. In addition to using several units on their heavy equipment, they are using the system to reduce the energy consumption of their crushers.

The crusher has been equipped with an Indurad iRTT-AU tag. It detects all vehicles in the vicinity of the machine. If the vehicle is an LHD or dump truck and it approaches the crusher within a certain range, the crusher PLC receives a signal to start the crusher. If the conveyor is empty and the vehicle leaves the area, the crusher stops.

A saving of €50,000 per year in energy costs has been reported. The entire crusher solution cost approximately €10,000, including installation and integration, so the payback time was 73 days.
