Rotating Screw

The SHW Rotating Screw is a discharge unit for dry and wet bulk materials that are difficult to handle. The design of the discharge screw is individually adapted to the bulk material for example by using different scarifiers on the flights, inclination of the screws, etc. . The optional design with two opposing screw shafts increases the discharge capacity and reduces the material’s dwell time in the silo.

Applications

  • bulk material reception
  • bulk material interim storage with a volume up to 1,500m³
  • suitable for cylindrical silos of up to 25,000 mm diameter
  • discharge capacity up to 400 m³/h

Customer advantages

  • high availability due to very robust construction
  • optional wear protection increases the service life even with highly abrasive bulk materials
  • constant bulk material feeding across the whole silo cross section
  • easy to install and maintain

Production waste from a saw mill is stored in a bolted drive-through loading silo and – according to requirements – loaded on trucks and delivered as raw material to subsequent production facilities. Within the silo a SHW rotating screw provides for a safe and metered discharge to the incoming trucks.

To ensure a continuous feeding of a MDF-board production, SHW delivers a silo discharge system for a large storage silo to Mexico. This silo plant is used as an intermediate buffer of the raw material between the wood yard and the downstream MDF board production and eliminates the production fluctuation of its own wood chips fabrication and the irregularities on delivery of foreign wood chips.
