In the world of open-pit mining, conveyor belts and their drives are subjected to extreme loads in extraordinarily harsh conditions. Strong vibrations and shaft currents also have a negative impact on the encoders and accelerate their wear. Our new case study reveals how Hübner Giessen helps to reduce the impacts of these hazards.
Minimizing encoder wear
Engineers face a number of major challenges when designing conveyor belt systems for open-pit mining. The length of the conveyor belt systems, the weight of the material being transported, and many other factors often lead to strong oscillations and vibrations in the system. Shaft currents can additionally place a high load on the encoders in the drive system and cause damage. Against this background, particularly robust and vibration-resistant encoder solutions are required for conveyor belt systems in open-pit mining.
Finding tailor-made heavy-duty solutions
To optimally compensate the shaft currents and extend the lifetime of the encoders, Hübner tackles the challenge by focusing on two aspects: the mounting situation of the encoder and the type of encoder bearing. When doing so, the Hübner experts always adapt the encoder system to suit the respective situation on site at the open-pit mine. Our new case study on “Conveyor Belts / Motors: an incremental heavy-duty encoder braves the harshest mining conditions and provides reliable speed control” provides detailed information on what a long-living heavy-duty encoder solution for conveyor belt systems can look like.
