Which is the appropriate crusher for my application?

Listen here to the full article

There are three main types of crushing plants which are used both in quarrying and in the recycling of building materials. These plants are differentiated according to the type of crushing tools. There are jaw crushers, impact crushers and cone crushers. In addition to these plants, we also know roller crushers, but these are not very common. The choice of system depends on the raw material. Is the system to process stone extracted from the quarry or is it for recycling building materials? Of course, the desired material to be produced during processing also plays an important role. Last but not least the expected capacity plays a significant role. All types of crushers have advantages and disadvantages. The costs for wear and tear are the most important parameter. PDF

Buying used instead new?

New and modern crushing plants have many advantages. Overload protection, oversize grain recirculation, hydraulic gap adjustment and low-emission engines are state of the art. However, these plants come at a price. Good quality used machines are a good alternative.

Where to find good quality equipment?

Ideally, you should have a dealer in your home country where you can view and test a system. The dealer will often also provide good advice on whether the system is the right one for the task at hand. He will advise you on whether the feed material, the expected result when crushing and the capacity of the plant are suitable for your tasks.

However, due to the limited number of available systems, you often have to search far and wide. Most used machines are listed in the common databases for used heavy machinery.  A wide selection of those websites is available at www.used-equipment.de. And regardless of whether the system is purchased near or far, it makes sense to send a mechanic to inspect it who also understands this technology.

Buying directly from contractor?

Buying from an entrepreneur often seems attractive because of the significantly lower price. You can perhaps also expect a more honest description of the crushing plant and the experience with it. However, this should only be done at home. When buying from abroad, problems quickly arise that the contractor is unable to solve. This starts with the handling of VAT and does not end with the export documents.

How to inspect a used crusher?

During the operation of crushing plants, enormous forces are exerted due to the weight of the material. Shocks and vibrations play an important role. And the plants are usually exposed to high levels of dust. The intensity of this stress has a major impact on the wear and service life of components. Experienced engineers from the recycling plant sector know the weak points and know where to take a closer look.

You should always use a checklist for the respective type of system so that you do not overlook any assemblies. Professional inspection companies such as Mevas can read out the engine data for many systems. The oils used can also be analysed. Each system has specific assemblies and the technician should be familiar with these and know how they ideally work. This allows the remaining service life and problems to be interpreted.

Cost for using a professional Mevas inspector

Mevas has inspectors for all types of heavy equipment. In 25 countries, local inspectors can assist with a professional inspection for crushers and screens as well as other construction and mining equipment. The final price for an inspection depends very much on the location of the machines, the scope of the inspection and the size of the equipment. Typically, the fee starts at €800 for a single piece of equipment. The inspector records a video and many images during operation and compiles a detailed report based on a 60-point checklist for the crusher inspection. Get in touch with Mevas for a quotation now.

What to Inspect and How during an Excavator Inspection

When purchasing a used excavator, conducting a thorough technical inspection is essential. This advice also applies to other construction machinery.

Beyond evaluating external features like dented panels or paintwork, it’s crucial to delve into the technical details. For the engine, check the exhaust pattern, oil condition, coolant, and blow-by rate. A visual inspection of the boom and stick is straightforward, but a specialist should measure the play in the slewing ring to assess wear. 

One critical component is the hydraulic pump, whose performance can be evaluated through a specialized test. Ensure the hydraulic oil is at operating temperature before testing. Supplement this with measurements of the main pump pressure and control pressure. Additionally, inspect the hydraulic cylinders for internal leaks and check the travel motors and final drives. Using a professional inspection checklist will help ensure no component is overlooked.

What to Do if the Machine is Too Far Away

Regional inspection services are available in many countries, though they can be slow, costly, and not always specialized in construction machinery. MEVAS offers a more efficient solution with their international and professional construction machinery inspection services.

Professional Construction Machinery Inspection Service

MEVAS inspectors are available for Ritchie Bros. or P&E auctions in Dubai (U.A.E.), Caorso (Italy), Moerdijk (Netherlands), and many other locations. The team, based in Germany, provides inspections across all European countries, with inspectors even available in China and Chile.

Verifying Excavator Working Hours

While an inspection reveals the current state of an excavator, understanding its history can be invaluable. Specialized companies like MEVAS can download data from the internal computer of some machines. If this isn’t possible, there are often other ways to investigate the machine’s history.

What can the machine’s oil tell us?

If you know the service life of the engine oil or hydraulic oil, an analysis of the oil components can tell a story. Too much silicon in the oil indicates external contamination. Too much copper or chromium tells us something about the wear in the hydraulic pump and the hydraulic cylinders. Soot in the engine oil provides information about the condition of the engine. And how much does the analysis cost? You can have an in-depth analysis carried out in a certified laboratory for as little as $120 per oil. Ask MEVAS for more details.

Digging even deeper?

For an in-depth analysis of the machine, you can even open the axle drives and look for chips on the magnetic drain plugs. The swing and boom lift cycle times can be compared to factory specifications. Even the engine blow-by effect can be measured.

How Much Does an Excavator Inspection Cost?

The cost of an inspection includes the travel and labor of the inspector. However, in our experience, an inspection is less expensive than repairing a hydraulic cylinder. It all depends on the location of the machine, the size of the excavator and the extent of the inspection required.

A comprehensive inspection report can help you negotiate the price of any necessary repairs to the machine. So it often pays for itself.

Safety advice when buing used heavy equipment

In many countries, there are no high-quality used construction machines available. Therefore, it is a good idea to import them. The question is: where can you find good machines? Many websites advertise construction machinery. One example is Middle-East Plant & Equipment.

Who Provides Machine Data?

What are the risks of buying used construction machinery? When looking for machines, remember that all information is provided by the seller. Sellers may only give information that helps them make a sale. Before making any purchase, verify the credentials of the seller. Check for reviews, ratings, and any complaints from previous buyers. Trusted sellers usually have a good track record.

Repainted and Incorrectly Labeled Machines

We often inspect machines in China for our customers. We have found many copied or mislabeled machines. For example, we found a CAT 966H wheel loader that was not a real Caterpillar. It had a Cummins engine and an old air brake system. Sometimes, smaller excavators are labeled as larger models, like a Volvo EC290 labeled as a Volvo EC360.

Recommended Machinery Portals

We do not recommend a specific portal. However, it is safest to use websites where the seller’s identity and location have been verified. However, a selection of portals is visible at www.used-equipment.de

Dangerous Places to Buy From

Creating a website and selling construction machinery can be easy and cheap. Some people create fake websites, copy photos from other sites, and offer machines at very low prices. They might ask for a deposit to reserve the machine. Be very careful if a deposit is required before you see the machine.

What to Check When Buying a Used Machine

If you do not know the seller or have not received a recommendation, always send someone to see the machine. Using a professional inspection service like Mevas is a good idea. They will confirm if the machine exists and provide a detailed inspection report with photos and videos. Ask the supplier for maintenance records of the machinery. These records can provide insights into how well the machine has been cared for and if it has had any major repairs.

What to Pay Attention to When Paying

Check the seller’s account number. It should be in the same country as the seller. Call the seller’s accounting department to verify the number. Avoid paying via Western Union or with cryptocurrencies. It is better to spend an hour checking the website and the offer than to lose $10,000.

Secure Transportation and Machine Certification

Ensure that the machinery is transported securely. Hire reputable logistics companies that specialize in transporting heavy equipment to avoid any damage during transit. If you are importing machinery, be aware of the import regulations in your country. This includes understanding any duties, taxes, or restrictions that may apply. In some countries it is required to have a CE certification or to comply with emission regulations.

What means Heavy Equipment Procurement?

Heavy equipment procurement is the process of acquiring the large machinery needed for industries like construction, mining, agriculture, and forestry. This involves identifying the specific equipment requirements, finding qualified suppliers, negotiating the best price and terms, and finally finalizing the purchase.

Here’s a breakdown of the typical heavy equipment procurement process:

1. Identifying Needs: The first step involves understanding what kind of equipment is needed. This considers factors like project requirements, budget, and existing equipment inventory.
2. Supplier Research: Once the needs are identified, potential suppliers who can provide the required equipment are researched. This may involve contacting manufacturers, distributors, or even used equipment sellers.
3. Qualification and Selection: Suppliers are then evaluated based on factors like experience, reputation, pricing, and after-sales support. A shortlist of qualified suppliers is created for further negotiation.
4. Negotiation and Contract: Negotiations with shortlisted suppliers are conducted to get the best possible price, financing terms, and delivery schedules. Once an agreement is reached, a formal contract is signed.

Obtaining heavy equipment can be a significant investment, so the procurement process aims to ensure efficient use of funds and the acquisition of equipment that meets the project’s needs.
