We convey solutions

Schrage Conveying Systems is your specialist for
tube chain conveyors – worldwide.

For more than two decades, we have been planning and
implementing conveyor systems for various bulk solids
and many industries – individually suited to your needs.
Our tube chain conveyor also reliably transports your
bulk material from A to B.

Schrage tube chain conveyor: horizontal | upright | vertical

  • Schrage tube chain conveyors are conveyor systems
    for a wide variety of industries. It is possible to transport
    abrasive, toxic, explosive, or adhesive bulk material or
    even materials with high temperatures.
    The tube conveyor is available in different designs:
    horizontal, vertical, diagonal, or a combination thereof
    and in five different sizes: 115, 135, 160, 200, and 270.
    It is in this way that the layout, speed, and materials
    can be optimally adjusted to suit your bulk material.
    The conveyor system transports bulk material with
    grain sizes of up to 100 mm, a bulk density of up to
    7 t/m³ or more, and flow rates of up to 80 m³/h. 
    The maximum size per leg is 60 m horizontally or 40 m
    vertically.
    The advantages of the modular chain conveyors are
    their flexibility and nearly unlimited application
    possibilities, such as easy vertical conveyance, multiple
    inlets and outlets, or the conveyance of bulk materials
    in two directions simultaneously.
    The low chain speed is perfect for ensuring the gentle
    handling of the products.

  • The conveyor system is absolutely dust-tight with
    a high selfcleaning capacity and virtually no dead
    space and, if necessary, can be designed to meet
    all the ATEX requirements.
    Schrage chain conveyers feature low maintenance,
    easy handling, and high operational reliability.
    They require very little space and will quickly
    pay for themselves due to their low energy
    requirements and low operational costs.

      The slide flap makes
      the tube cutout inside
      the chain conveyor flap
      down. If necessary, the
      conveyor chain can be
      nozzle sprayed, shaken,
      or rinsed from above.

      The entire tube opens
      and closes the way
      scissors do. It is in this
      way that the transfer
      of the bulk material
      from one system to
      another is controlled.

      Flat slide valves for tubes

      Flat slide valves for
      tubes are the most
      economical solution,
      if dead space above
      the slide plate is not
      a problem. They are
      actuated manually,
      pneumatically, or
      electrically driven.

      Revolving tube discharge

      This system controls
      the discharge of the
      bulk solids by means
      of a pivoted tube with
      an opening. Optimum
      residual product dis-
      charge can be gained
      in combination with a
      forced discharge system.

      Slide valves serve as
      discharge valves and
      reduce the material
      flow completely or
      partially, depending
      on the position of the

      valve. Slide valves can
      be adjusted during

      Turn station

       

      In case of conveyed
      materials with more
      friction, the use of
      turn stations with
      rims or sprockets
      provides a good
      alternative. They
      prevent excessive
      wear and also noise.

      In the case of a change
      in direction, high-friction
      bulk material can cause
      problems. For this case
      we developed our 45°
      deflection, in particular
      for high vertical chain
      conveyors.

      To prevent sludgy

      to the inside of the
      tube, a variety of
      cleaning discs can
      be used inside the
      tubes, depending
      on the material to
      be conveyed.
