A rotary vibrating screen moves material across a circular screening surface. Particles are separated according to the selected openings and collected through the corresponding outlets. Start with the separation you need, then review the screen arrangement against your material and process.
| Item | What to Confirm |
|---|---|
| Screen opening | Target opening in µm or mm; identify the standard if using mesh |
| Separation | Oversize removal or required size fractions |
| Material | Particle size, moisture, bulk density and flowability |
| Throughput | Required kg/h or t/h and feeding conditions |
| Deck arrangement | Number of separations and collection outlets |
| Installation | Inlet height, outlet positions and cleaning access |
A rotary vibrating screen moves material across a circular screening surface. Particles are separated according to the selected openings and collected through the corresponding outlets. Start with the separation you need, then review the screen arrangement against your material and process.
For a powder screening enquiry, describe the particle size range, moisture and any tendency to form lumps. Explain whether the aim is to remove oversized particles or collect a particular fraction. A material name alone does not define the screen opening.
Material enters through the top inlet and reaches the screen surface. The vibrating assembly moves the material across the mesh. Particles that pass through an opening move to the level below, while larger particles remain above that opening and leave through a separate outlet.
Where more than one screen deck is used, different openings can create several collected fractions. The deck sequence and discharge arrangement must match the intended separation. A multi-deck illustration explains this arrangement, but does not establish the number of decks supplied with a quotation.
Screening is a size-based separation step. It should not be described as sterilisation or as guaranteed removal of all contamination. The required cut, material behaviour and acceptance criteria need to be defined for the actual process.
For granules, identify each fraction you want to collect and how it will be used downstream. Check the required outlets and collection space before choosing a deck arrangement. Additional decks should follow the separation task.
Share inlet height, outlet positions and space for screen changes. Specify which contact parts require a particular material grade and describe your cleaning method. These details should be reviewed together with the screen configuration.
For powder enquiries, identify whether the task is final screening, oversize removal or another size separation. For granules, list the fractions that should be accepted or rejected. The same material may need different screen openings at different stages of production.
If you are considering flour, starch, chemical powders or plastic granules, provide the actual material properties and intended duty. These are enquiry examples, not a statement that every grade of each material is suitable or that a particular hygiene or safety certification is included.
Specify the opening in microns or millimetres where possible. If using a mesh number, identify the relevant standard. Define the required material grade for contact parts separately from the base and external components. Include seals and the cleaning method in the same review.
When fine powder blocks the mesh, describe the observed problem and any existing cleaning arrangement. Ultrasonic assistance or other options require a separate suitability check; they should not be assumed to be included in a standard rotary screen.
Share the upstream and downstream equipment and explain how they operate together. Identify whether this machine runs continuously, starts with another process or handles separate batches. These details help define the connection and control requirements.
Provide the available floor space, connection heights and access around the equipment. Include nearby structures that may restrict installation or maintenance. Confirm dimensions against the proposed configuration before arranging permanent connections.
Explain the cleaning method, product-change frequency and access available to the operator. Ask which parts need routine inspection and which items may require replacement. Maintenance instructions and isolation procedures should come from the documentation for the selected equipment.
Discuss the equipment scope together with your separation requirements. Identify whether the quotation includes the drive, controls, supports, connections and requested accessories. Confirm these items individually rather than assuming that everything shown in an illustration is supplied.
Provide the destination country and your packing, documentation or spare-part requirements. Review the agreed configuration, commercial terms and delivery responsibilities before ordering.
