Posted on by in English posts, International-Posts

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.

Buying used machines in South Africa

Posted on by in English posts, International-Posts

How can I check if a used machine is in good condition?

South Africa is a gigantic market for the mining and construction industry. Manufacturers from Caterpillar to Liebherr and Bell are present with branches and sales. Mining and construction companies have a great need for machines. As a result, used machines keep coming onto and from the market.

Export to other African areas

Due to the short transport routes, the machines are of interest to many construction companies and mines in other parts of Africa. So what could be closer to buying machines there? Of course, it would be good to know whether the machines are in reasonable condition.

Which company can inspect machines in South Africa?

Mevas has local inspectors available in South Africa which can help with the inspection of used construction equipment and civil engineering. Qualified engineers inspect the machines, create a report, take various photos and can also create a video of the machine in operation. Our team knows about excavators, wheel loaders, motor graders, backhoe loaders, quarry trucks, and bulldozers. We check a single machine as well as fleets of machinery.

How to check the hydraulic pump?

Posted on by in English posts, International-Posts

How can I check if my excavator hydraulic pump is working well?

In the event that the hydraulic excavator does not have enough power or even when buying an excavator, it is useful to check whether the hydraulic pump has enough power. Normally, however, you do not have any equipment for measuring pressure with you. Don’t forget that pressure alone is not a criterion for sufficient power. You would also have to measure the volume of the oil flow.

Hydraulic Pressure Testing during inspection of an excavator

So what can be done to check the performance of the hydraulic pump?

An excavator usually has a so-called load-sensing pump. The pump’s sensors constantly check the pressure and the oil volume demanded. The pump permanently adjusts the volume flow and the pressure to the requirements during work. To check performance, an experienced inspector will usually test whether the excavator can make three different working movements at the same time without slowing down the flow of one working movement. For example, lifting the boom, extending the arm and extending the bucket at the same time. The inspector must note whether there are one or more hydraulic pumps for the different components. Often the traction drive has a separate pump.

Pressure test for comparison with the manufacturer’s data

The type of test described so far is helpful if you do not have a pressure gauge available. However, for a more accurate test of performance, it is helpful to be able to measure pressures. To do this, the inspector needs to connect a pressure gauge to the test ports and measure the pressures for the pump and the pilot pressure. The recorded data must be compared with the manufacturer’s specifications.

Hydraulic-Pressure gauge for excavator testing

Which company can inspect an excavator with pressure measurement?

Some MEVAS inspectors are equipped with dial gauges. We can offer a very thorough examination of the condition of used hydraulic excavators in various countries. Of course, we are also responsible for any other construction machine and for large equipment from the mining industry. The guide can be downloaded here.

How to measure swing bearing play?

Posted on by in English posts, International-Posts

Excavator swing bearing play measuring

The swing bearing is one of the weakest points in the structure of an excavator. At this point, the stable undercarriage, the so-called X-frame, is connected to the superstructure. The superstructure rotates endlessly on this pivot. On a larger excavator, you will find a counterweight weighing perhaps 15 tonnes. It balances the whole machine and is designed to keep the machine stable and balanced with the arm extended and the bucket full. On the other hand, this means that when the bucket is empty and the arm is close to the machine, the rear side of the machine is loaded.

To ensure that everything runs well, the pivot bearing, also called the slewing ring, has several lubrication points. Ideally, these are supplied with grease of the right consistency by an automatic lubrication system.

Swing bearing play measurement for excavator

The rollers or rolls of the large bearing now run permanently over the running surfaces, generating wear through friction and pressure. At some point, the play becomes so large that machine safety is endangered. When inspecting a used excavator, it therefore makes sense to measure whether the play is still within the permissible tolerance.

How to measure?

To do this, the slewing ring must be loaded once and then unloaded again after the dial gauge has been placed on it. The play is measured between these two states. Most inspectors for construction machinery know the procedure. Depending on the equipment of the machine, one must decide whether a filled excavator bucket is sufficient to achieve the load on the front, or whether additional weights are required. Also the use of a hydraulic jack can be considered.

When to measure, cost for replacing?

Our inspectors have the necessary knowledge to carry out a measurement correctly. During used machine inspection process the inspector does a functional test. Experienced technicians can feel already at this stage if a measurement is required. After the measurement, we can help to decide whether the play is acceptable or whether you need to replace the slewing ring. The Liebherr R964 excavator pictured above had 5mm clearance across the front of the frame and 4.7mm across the side. It is not safe to continue working with this slew ring. Exchange will cost probably more than 12.000 $

Used shredder wanted?

Posted on by in English posts, International-Posts

Who can inspect used shredders and recycling equipment?

The search for used recycling technology is not so easy. Once you have found what you are looking for, the question is whether the machine is in good condition. We offer technical inspections for such equipment to check that.

Whether high-speed or low-speed, the bearing arrangement of the shredder rollers must be examined. Additional equipment such as hammers etc. must be looked at closely. In shredders sometimes material is fed by roller or chain conveyors. The technician must therefore understand how the plant is constructed and which component has what function. We have the necessary background knowledge.

Mevas inspectors are available in Europe and many countries around the globe. And we are constantly expanding our network to support our customers in the best possible way.

We do not deal in technology ourselves, all we do is inspect used machines.

Caterpillar TA2-level inspection ?

Posted on by in English posts

What is a CAT TA-2 inspection ?

There are different types of inspections for used Caterpillar machines. There is the TA1-level for a standard inspection and the TA2-level for inspections with more in-depth investigations.

10 minutes video about TA1 and TA2 inspection level

In line with the needs of our customers, we generally offer inspections at the TA1+ level. Can you imagine what that means? It is a visual inspection that includes a performance test and a functional test. Engines, gearboxes and torques are tested by running the machine. Tyres or Undercarriage are measured and estimated for remaining life. A detailed inspection checklist is prepared and photo documentation is taken. The so-called Product Status Report PSR is downloaded from the ECMs. And we look out for weak points on the equipment. If you have questions afterwards, we are there for you and answer them quickly.

Is a CAT TA-1 inspection sufficient?

For larger machines, a TA1 inspection is often not sufficient. Machines have a service life that far exceeds that of a standard earthmover. For these machines we offer an extended inspection service similar to TA2 on request. Our engineers do filter cutting, oil sampling, opening the final drives and take cycle times. We know the required specifications for CAT-equipment. For midsize and smaller machinery a TA-1 Plus is the best solution.

By the way, the level of a CAT-TA inspection applies as well for all other brands such as Liebherr, Komatsu, Hitachi or Volvo CE. If you are looking for used heavy machinery try a search here.

Do you have any experiences with Caterpillar TA2-level inspections? Let us know in the comments below.
