Make and Model : Doppstadt SM 518.

2. Construction and Components

• Make and Model : The rotary screen used is a Doppstadt SM 518. This model is built to last and withstand harsh working conditions.

• Main Components:

  • Rotating Drum : The heart of the machine, with dimensions of 4,700 mm in length and 1,800 mm in diameter. It is made to withstand wear and tear and heavy loads.
  • Engine : Mercedes Benz engine with a power of 41 kW (60 HP), designed to ensure efficient and constant rotation of the drum.
  • Support Frame : Sturdy structure that supports the drum and allows it to rotate.
  • Feeding System : Introduces materials into the drum for screening.
  • Discharge System : Expels separated materials after screening.

• Measurements and Characteristics:

  • Drum Length : 4,700 mm
  • Drum diameter : 1,800 mm
  • Drum Perforation : Variable from 10 mm to 80 mm, allowing precise adjustment of particle size.
  • Drum Thickness : Variable from 6mm to 12mm, influencing the strength and capacity of the drum.
  • Weight : 13,000 kg

3. Procedure for Use

• Installation:

  1. Positioning : Place the rotary screen on a flat and stable surface.
  2. Connection : Make sure the engine and fuel system are properly connected.
  3. Alignment : Verify that the drum is aligned correctly to avoid vibration and excessive wear.

• Normal Operations:

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

4. Matching Accessories

• Interchangeable Nets : Different nets to adapt the size of the holes according to screening needs.
• Conveyor Belts : To facilitate the transport of materials before and after screening.
• Control Systems : To monitor and regulate the rotation speed and flow of materials.
• Cyclones and Separators : For further separation and filtering 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 length and diameter of the drum.

6. Materials He Can Work with

The SM 518 Doppstadt rotary screen can work with:

• Earth and Sandblasting
• Construction Materials
• Compost and Organic Waste
• Industrial waste

It is not suitable for excessively wet or too large materials without adequate pre-treatment systems.

7. Maintenance

• Periodic Inspection : Inspect the drum and support frame for signs of wear and damage.
• Lubrication : Make sure the motor and drum bearings are adequately lubricated.
• Cleaning : Remove debris and accumulated materials from the drum and surrounding areas.
• Inspection : Regularly check the mechanical parts and replace worn or damaged ones.

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

• External Conditions : Check the condition of the drum and support frame for signs of wear or damage.
• Operation : Test the machine to make sure there is no vibration and abnormal noise during operation.
• History of Use : Request information on history of use and maintenance to evaluate durability and reliability.

9. Sectors of Use

The SM 518 Doppstadt rotary screen is used in:

• Mining Sector : Separation of minerals and aggregates.
• Waste Management : Solid waste screening and composting.
• Construction and Demolition : Classification of construction and demolition materials.

10. Why it is better to buy it used

Buying a used rotary screen offers numerous advantages:

• Lower Cost : Significantly lower price than new.
• Immediate Availability : Ready to use without long waiting times for production.
• Sustainability : Contributes to environmental sustainability by reducing the need for new materials and resources.

The used and unserviced SM 518 Doppstadt rotary screen, with its robust dimensions and features, is an excellent choice for applications requiring effective material separation. If you have any other questions or need more details, I'm here to help!
