Storage and carrying of bulk materials

Storage and carrying of bulk materials
  • The areas of application of the ORBILAN PE 8000 materials group include all activities of transporting, distributing or storing bulk materials. Thanks to their good sliding properties and excellent wear resistance, these materials are the perfect choice for lining and wear plates in

    • silos and bins
    • railway wagons
    • bulk material ships
    • wheel loaders and bucket wheel excavators
    • conveying troughs and vibrating chutes

    Other properties:

    • low absorption of water, no moisture expansion
    • good chemical resistance
    • good noise damping

    If an application requires anti-static properties, we recommend using ORBILAN PE 8000 AST. This material has anti-static and UV resistant  properties by adding a special, conductive carbon.

    Panel Thickness and Fastening

    The panel thickness of ORBILAN-lining panels depends in abrasivity of the bulk material. Typical panel thicknesses range from 12 mm to 30 mm. For particularly abrasive strain panels up to 40 mm are used.

    The lining panels can be easily factured to steel or concrete. In practice, a distribution of approx. 20 fastening points per m2 on steel and approx. 25 fastening points per m2 on concrete has
    proven reliable.

    Arching, shaft formation, caking and irregular discharge are typical problems related to storing bulk materials. These issues mostly result from poor sliding properties of the silo or bunker or the angles of the silo or bunker funnels being too flat.

    Due to the good sliding properties of ORBILAN lining panels, a troublefree flow of material is guaranteed and costintensive interruptions of the operating activities are prevented.

    Irregular Flow

    Irregular flow occurs during bulk material discharge when temporary arches or shafts form and immediately collapse again. This can lead to so-called shooting of bulk material, involving the development of large dust clouds, therefore putting at risk downstream plants. Irregular flow can be prevented through
    lining with particularly good sliding properties and large outlet openings.

    Arching

    If a stable arch is formed over the outlet opening, so that the flow of bulk material is stopped, it is called arching. Arching can be prevented through
    lining with particularly good sliding properties easily large outlet openings.

    Shaft formation

    Shaft formation occurs in funnel flow silos when only the bulk material lying vertically above the outlet opening is discharged. Due to the solidity of the bulk material, the rest of the bulk material remains in the silo and forms a shaft. Shaft formation can be prevented through lining with particularly good sliding properties.

    Caking

    Caking occurs when particles of bulk material compress in the dead zones (e.g. with shaft formation) and increasingly solidify. In extreme cases, the bulk material can only be brought into motion again with great effort. Shaft formation can be prevented through lining with particularly good sliding properties.
