Non - Pressurised Screw Feeders

Conveying Solution

"Non Pressurized Screw Feeders are mechanical continuous conveyors, where material to be conveyed is moved inside a closed trough by rotating shaft with additional flights"

Description for the Non - Pressurised Screw Feeders .

SALIENT FEATURES:-

  • The feeder trough in non-pressurized screw feeders 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.
