2. Construction and Components

• Make and Model : The rotary screen used is a Doppstadt SM620, known for its robustness and ability to handle heavy, bulky materials.

• Main Components:

  • Rotating Drum : The drum is one of the key elements of the screen, designed to resist wear and mechanical stress.
  • Motor : Powerful motor that ensures continuous and stable rotation of the drum.
  • Support Frame : Robust structure that supports the drum and ensures the stability of the machine during operation.
  • Feed and Discharge System : Mechanisms that feed materials into the drum and remove the screened materials.

• Measurements and Characteristics:

  • Drum:
    • Length : 5,500 mm
    • Diameter : 2,000 mm
  • Transport Measures:
    • Length : 11,900 mm
    • Width : 2,550 mm
    • Height : 4,000 mm

3. Procedure for Use

• Installation:

  1. Placement : Make sure the sieve is placed on a flat, stable surface.
  2. Connection : Check that all electrical and mechanical connections are secure.
  3. Alignment : Check that the drum is aligned correctly to avoid vibration and wear.

• Normal Operations:

  1. Starting : Turn on the engine and start the rotation of the drum.
  2. Loading of Materials : Introduces the materials to be screened through the feeding system.
  3. Screening : The materials are passed through the rotating drum, which separates the particles based on the size of the holes in the screens.
  4. Discharge : The separated materials are expelled via the discharge system.

4. Matching Accessories

• Interchangeable Nets : Allow you to adapt the screen to your specific screening needs.
• Conveyor Belts : To facilitate the movement of materials before and after screening.
• Control Systems : To monitor and regulate drum speed and material flow.
• Cyclones and Separators : Used for further separation of materials.

5. Formulas for Optimal Use Parameters

• Rotational Speed ​​(N):

  $$N$$

  where RPMRPM $RPM$ is the rotation speed of the drum and DD $D$ is the diameter of the drum.

• Screen flow rate (Q):

  $$Q$$

  The volume per cycle depends on the size of the drum.

6. Materials He Can Work with

The SM620 rotary screen can work with:

• Compost and Organic Materials
• Earth and Sandblasting
• Rubble and Building Materials
• Solid Waste

The drum is designed to handle a variety of materials, but may require modification to handle excessively wet materials or very large particles.

7. Maintenance

• Periodic Inspection : Check the drum and frame for signs of wear or damage.
• Lubrication : Make sure the motor and bearings are properly lubricated.
• Cleaning : Remove debris and accumulated materials to maintain optimum performance.
• Inspection : Check mechanical parts regularly and replace worn ones.

8. How to understand if it is a good used one

• External Conditions : Check the drum and frame for signs of wear and damage.
• Operation : Test the machine to ensure it operates without vibrations and strange noises.
• Usage History : Request usage and maintenance history to assess overall health.

9. Sectors of Use

The Doppstadt SM620 rotary screen is used in:

• Agricultural Sector : For screening compost and organic materials.
• Waste Management : Solid waste separation and composting.
• Construction : Classification of building and demolition materials.
