Screw Conveyor


Time-tested equipment for transportation of dewatered sludge and various types of garbage collected from screens in sewers.

Esmil Screw Conveyor it’s time-tested equipment for the transportation of dewatered sludge and various types of garbage collected from screens in sewers.

Application of the Esmil Screw Conveyors

  • Sewage treatment plants
  • Sewage pumping stations
  • Treatment facilities of industrial enterprises
  • Water supply constructions

Advantages of Esmil Screw Conveyors

  • Wide range of performance and applications
  • Available configurations: suitable for transporting various types of waste or sediments over long distances.
  • Possibility of installation at an angle up to 30 degrees for axisless and up to 45 degrees for axial conveyors.
  • The modular design of the screw conveyors allows a wide range of configurations.
  • The conveyor may be hermetically sealed together with other units of wastewater treatment equipment.
  • Special inserts of high-hardness steel alloys used in the casing, allow transportation of abrasive materials.
    The minimal gap between the casing and the screw guarantees high productivity.
  • The use of a special worm gear motor by NORD Drive Systems ensures high-reliability
  • Production of conveyors in two versions: pushing or pulling.
  • Flexible control of the conveyor operation, reduction of energy consumption and protection against power surges, which is ensured by the use of frequency control.
  • Production of the screw in the form of separate sections without a central shaft.

Convenience of operation and maintenance of Esmil Screw Conveyors

  • The ability to transport even bulk materials;
  • Synchronization of screw conveyors with other equipment to facilitate system management and reduce energy consumption;
  • The use of double and triple composite screws can effectively solve the problem of transporting sludge with a large specific gravity over long distances;
  • The maintenance of drainage areas in the conveyor to drain excess fluid;
  • Enclosed design that guarantees an accurate and safe workspace and no unpleasant odors;
  • There is no need for constant technical maintenance;
  • If necessary, screw replacement is carried out with minimal time and labor;
  • Ideal conditions for maintenance – conveyors are equipped with removable covers, and the main working units are available for inspection.

Optional equipment for Esmil Screw Conveyors

  • adaptation for outdoor use;
  • telescopic stand;
  • ultrasonic level sensor;
  • performance adjustment by a frequency converter;
  • protection of screw jamming and breaking.

Durability of Esmil Screw Conveyors

  • High corrosion resistance: the housing is made of AISI 304 or AISI 316 stainless steel.
  • Anticorrosion treatment, including volume etching and passivation by special means.
  • Reliable and robust design. A conveyor is an independent unit with the working body which is a steel screw without a central shaft.
  • Equipment of enclosures with special inserts to protect against abrasion by the rotating screw.
  • Axis-free screws are made from special high-strength steel grades.
  • Electrical protection against overloads and voltage surges.

Is it possible, if necessary, to change the speed of the screw?

The screw speed can be changed. It depends on its diameter and the nature of the transported material.

How safe are Esmil screw conveyors in operation and maintenance?

The conveyor has a robust and completely enclosed construction, the absence of external moving elements significantly increases safety in operation.
