User-oriented characteristics:
KRUMMENAUER puts high value on durability in the whole construction as well as in details. E.g. the complete water pipe system is available in corrosion-resistant material to ensure no need for maintenance.The parts of the drum, which unterlie high abrasion, are casted for durability. KRUMMENAUER products are leading the field of durability in international comparisions.
Our products excel at high maintenace und repair requirements. E.g. the optional screwed face ring, a part with heavy abrasion, can be easily replaced. Due to the strong construction of KRUMMENAUER shearer drums, they can be repaired multiple times to reduce overall costs for the mines.
KRUMMENAUER drums and face rings can be delieverd in divided versions. That makes the handling of drums with large diameters a lot easier. Due to our sophisticated construction the division has no influence on the stability of the shearer drums.
