Who can offer inspections for used screen plant in Europe?

Mevas is known as a inspection service for used construction machinery. Did you know we also inspect screening and processing equipment? Mobile Crushing & Screening Equipment is often in bad condition when it hits the used-market. Screening plant, especially when used in recycling aggregate applications have in many cases worn screen boxes. Tough job to exchange.

What to look for when buying used screen equipment?

Conveyors have damaged belts and seized rollers. Often, we see cracks in frames and leaks on hydraulics. Of course this is just the special part of inspection. All other components of a used screen are of course inspected as well. Our inspectors use a detailed screen plant inspection checklist. We can offer inspections in all areas of the Europe.

We hope our article was helpful for you. Feel free to comment below the post about your experiences looking for used screening equipment.

What is a screening plant needed for on the construction site or in the quarry?

A screening plant, also known as a screening machine or screener, is a piece of equipment used in construction sites and quarries for the purpose of separating and classifying materials based on size or other characteristics. Screening plants play a crucial role in the construction and quarry industries for several reasons:

1. Sorting and Separating Materials: Screening plants are used to sort and separate materials, such as aggregates, soil, sand, gravel, and crushed stone, into different sizes or grades. This is essential for various construction applications.
2. Quality Control: Screening plants are employed to ensure that the materials used in construction meet the specified size and quality requirements. They help eliminate oversized or undersized particles, which can affect the quality and performance of the end product.
3. Aggregate Production: In quarries, screening plants are often used to produce different grades of aggregate materials, which are essential components in concrete, asphalt, and other construction materials.
4. Environmental Compliance: Screening plants are used to remove debris, contaminants, and foreign objects from soil and other materials, ensuring that they meet environmental standards before being used in construction or other applications.
5. Recycling Operations: In recycling facilities, screening plants are used to separate recyclable materials from waste and to classify materials for further processing, such as the separation of construction and demolition waste.
6. Cost Efficiency: By separating materials into different grades, screening plants enable the efficient use of resources, as the right materials can be used for specific tasks, reducing waste and improving cost efficiency.
7. Increased Productivity: The use of screening plants can significantly increase the productivity of construction and quarry operations by automating the process of material classification and reducing the need for manual sorting.
8. Uniform Product Quality: Screening ensures that the final product, whether it’s aggregate for concrete or other materials, is consistent in size and quality, leading to improved structural performance and overall quality.
9. Reduced Equipment Wear and Tear: By removing oversized or abrasive materials before they enter crushers or other processing equipment, screening plants help reduce wear and tear on downstream machinery.
10. Flexibility: Many screening plants are portable and can be easily transported to different job sites or areas within a quarry, providing flexibility in material processing.

Screening plants can vary in size and design, from small mobile units to large stationary systems, and they may use different mechanisms for classifying materials, such as vibrating screens, trommel screens, or scalping screens. The choice of screening plant depends on the specific requirements of the construction or quarry operation, the types of materials being processed, and the desired output sizes or grades.

How is a screening plant for the construction site or quarry constructed?

A screening plant for a construction site or quarry is typically constructed with several key components and follows a specific design and assembly process. Here’s an overview of how a screening plant is typically constructed:

The screening plant requires a stable foundation and support structure. This may involve the following steps:

• Site Preparation: Clear and level the ground at the selected location to create a suitable foundation.
• Foundation Construction: Depending on the plant’s size and weight, a concrete foundation or footings may be required to support the equipment.
• Support Structure: Assemble the support structure, including frames and mounts for the screening equipment and conveyors.

The core components of the screening plant include the screening equipment itself. This includes:

• Screening Machine: Install the chosen screening equipment, whether it’s a vibrating screen, trommel screen, or scalping screen, according to the manufacturer’s specifications.
• Screen Decks: If the screening machine has multiple decks or layers, assemble and arrange them for the desired material separation.
• Drive Mechanism: Install the drive system (usually motor-driven) for the screening equipment to power the screen.

Conveyor systems are often integrated into screening plants to transport materials to and from the screening equipment:

• Feed Conveyor: Install a conveyor to transport raw materials to the screening machine for processing.
• Output Conveyor: Set up conveyors to transport screened materials to the desired location, such as stockpiles or loading areas.
• Optional Conveyors: Depending on the specific design and needs, additional conveyors may be used for recirculating materials or sorting.

To ensure the efficient operation of the screening plant, you may need to establish certain support infrastructure, which can include:

• Water Supply: If water is required for the screening process (e.g., for washing or dust suppression), set up a water supply system.
• Electricity or Power Supply: Ensure a reliable power source, including electrical connections or generators, for the screening equipment.
• Control Room: If the screening plant is equipped with advanced controls, establish a control room where operators can manage and monitor the screening process.

Incorporate maintenance access points and safety features to ensure the plant can be serviced and operated safely:

• Walkways and Platforms: Create safe walkways and platforms for access to the equipment and for maintenance activities.
• Safety Barriers: Install safety barriers, guardrails, and warning signs as needed to protect workers.

Before putting the screening plant into full operation, conduct testing and calibration to ensure that it operates as intended and meets the required material classification criteria.

Train personnel to operate the screening plant safely and efficiently, and establish operating procedures and protocols.

Implement a routine maintenance and inspection schedule to keep the screening plant in good working condition and to address any issues promptly.

The construction of a screening plant is a detailed process that requires careful planning, skilled labor, and adherence to safety and environmental regulations. The specific design and construction can vary depending on the type of materials, the scale of the operation, and the chosen screening equipment.
