Surface temperatures of the corner edges of the bucket wheel excavator KU 800 in the mining of hard and difficult disconnectable materials

Ing. Vlastimil Moni, Ph.D., Ing. Lubomír Donát

The article describes an assessment of the operational surface warming of the five variants of the cutting edge geometry of the bucket wheel excavator KU 800/11 - K84 extracting upper soils containing a larger or smaller volume of difficult disconnectable materials at the Vršany open pit mine. Main goal was verification of the functionality of four new geometries in the operating conditions compared to the original solution and to determine the most suitable cutting geometry for the given mining conditions.

Keywords: cutting elements, cutting edge, durability, thermodiagnostics, temperature, mining machines
