Screw Conveyor With 3-4 Screws

  • Operating principle
  • Features
  • Specifications

The screw conveyor is available in a wide variety of designs and external dimensions, depending on the required application. Bulk materials are conveyed by:

  • Horizontal groove;
  • Bottom (semi-cylinder);
  • Screws of a specified length.

The machinery is available in three or four screw designs. The number of screws determines not only the size but also the total capacity of the machine.

The material flow into the volume to be served is determined by the trough openings. The material is ejected from the screw conveyors through the bottom (by means of the valve). The unit can move large quantities of product and doses them accurately. 

To simplify possible repairs and maintenance, the screw conveyors are implemented in a modular design. Rotation sensors and signalling devices, irrespective of the diameter and number of screws, are installed to ensure that the conveyor is not overloaded. A service hatch is also provided to monitor the screw overload.

Our screw conveyors are always the optimum choice for handling a wide variety of goods and materials. However, more often than not, designs are adjusted to the requirements of the particular industry. That is why additional options can be fitted:

  • Remote bearing lubrication units;
  • Hoods for mechanical insulation of the gear motor.
