Description for the Screw Conveyor.

Overview

• Long-lasting, easy to maintain screw conveyors are used for the dust-free,horizontal, inclined and vertical transport of fine-grained and floury materials.
• Suitable adaptations are made to handle coarse-grained, higher temperature, abrasive or poorly flowing materials.
• Screw conveyors also offer the option of multiple inlets and outlets.
• Various versions handle not only the transport of bulk materials but also emptying, metering, loading, screening and mixing

SALIENT FEATURES:-

• The conveyor trough in trough screw conveyors is manufactured as a torsionally rigid sheet metal housing made of standard section lengths with connecting flanges, to which are bolted sturdy cover plates.
• 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.

Ø  The shaft exit points are usually sealed by gray cast iron stuffing boxes.

• The screw shaft is designed as a solid shaft or a rigid tubular shaft with integrated end journals and a welded-on screw thread.

Ø  The end bearings are pedestal bearings with antifriction-bearing inserts.

Ø  When a screw shaft requires intermediate bearings for longer conveying distances. These are designed as easily replaceable units, the torque is transmitted by bolted couplings.

• We supply a plain bearing as standard with replaceable two-part, gray cast iron bearing shells. They can be set up for grease gun or central lubrication according to the operational conditions
• 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.
