SCREW CONVEYORS

SCREW CONVEYORS

The screw conveyors are designed to convey and dispense bulk materials. They are also used as mixers and silo unloaders.

SCREW CONVEYOR DRIVE
SCREW CONVEYOR DRIVE

As standard, we use NORD or SEW gear motors seated directly on the drive shaft to drive our screw conveyors.
Drive shaft bearings are mounted in SKF, SNR, KOYO housings located outside the conveyor frame. Lubrication points are outside the bearing unit covers.
Shaft glands guarantee 100% tightness even at high temperatures

SCREW SHAFT
SCREW SHAFT

It is made from a seamless tube. After the journals are welded in, it is machined in a single setup, which ensures perfect operation in the bearing housings.
The screw blades are made with a dedicated CNC rolling mill.
We manufacture screw shafts:

  • with a constant pitch of screw wheel blades,
  • with variable pitch,
  • with contra-rotating blades

It is made from a seamless tube. After the journals are welded in, it is machined in a single setup, which ensures perfect operation in the bearing housings. The screw blades are made on hydraulic presses and then welded onto the shaft using special templates

INSPECTION HATCHES
INSPECTION HATCHES

The manhole design allows for quick and safe access to the interior of the device and provides 100% sealing against dust, gases and liquids.

TROUGH SCREW CONVEYOR

The device features a modular design and its individual segments are U-shaped, allowing it to be mounted easily at the point of use. Depending on the destination, the conveyors may be provided with covers along their entire length. or not, if mounted under silos or funnels. For conveyors longer than 5 m, the intermediate screw shaft bearings are used. For this purpose, we use special SKF plain bearings.

TUBULAR SCREW CONVEYOR

The device features a monolithic design. This application allows for bulk material handling and the precise dosing of bulk materials.
As an option, the conveyors can be equipped with a totalising hopper weigher.
Max distance: 3 m.

MIXING SCREW CONVEYOR

The device may be either of monolithic or modular design depending on the length and place of installation.
Mixing screw conveyors are used where bulk material needs to be mixed during the horizontal transport, and the additional advantage of our devices is:

  • multiple stub pipes for probes to monitor the material being mixed,
  • multiple inspection hatches,
  • simple trouble-free design.
