There is also an inspection flap above the Casings, Drive Unit & Driven Unit. Abrasive materials can be handled by using manganese alloy steel, hard surface welding, fusion-cast basalt linings or material padding. Split end walls are bolted to the ends of the trough. This makes it easy to dismount the screw shaft once the metal cover plates have been removed. Intermediate supports are only required about every 6 meters. They are supplied loose for mounting during assembly. On request, we also supply antifriction bearings with split roller bearings in a sealed, grease-filled suspended housing. The drive comprises a standard geared motor unit.
