5 points that help in choosing the ideal screen for mining

Screening is one of the main stages of the mining process. During this phase, the materials processed are separated and classified into the final products desired by mining and quarrying companies.

Therefore, we decided to list 5 fundamental points for defining the equipment and the type of screening.

The equipment supplier needs to have experience in projects to offer efficient and durable equipment. Máquinas Furlan brings together these and other attributes.

Check out the following article and learn, for example, about the recommended sieve for different applications, such as rock for agribusiness and aggregates for construction, two best-selling products in the country.

Screening in a productivity scenario

In mining, screening involves the separation and classification of materials. This step needs to be properly adjusted to the crushing and grinding of rocks. Internally, this scenario will allow the company to be productive, reduce costs and operate safely.

Externally, the approach involves the quality of final products delivered to customers and meeting deadlines, in a highly competitive environment.

How to choose the ideal screen for mining?

So, what should you consider when choosing the ideal sieve model for mining?

We point out 5 items. Check them out.

1. Plant and production data

In this checklist, check the input particle size and moisture content of the material. Indicate the desired feed. Also consider the number of decks and meshes, as well as the mesh configuration of each deck.

One example is the production of aggregates for construction, which commonly involves 3-deck screens.

2. Efficiency at work

Continuous operation and delivery of a quality end product are critical.

The sieve must be correctly sized by specialists to allow the equipment to perform the correct separation, minimizing contamination of the desired materials (sieving efficiency).

Otherwise, the desired granulometries may contain a large amount of unwanted material, compromising the quality of the final product.

3. Maintenance is also important

The industry that plans its maintenance obtains better results. Equipment serviced on scheduled dates is more reliable.

In this sense, the conditions mentioned in item 2 are closely linked to the scenario.

Also set aside resources for staff training.

4. See the screening as a whole

Want a practical example of this item? A trend in mining is to seek greater productivity, often replacing a crusher with another with better performance. This change also requires reviewing the capacity of the screen in the same deposit.

Remember that the material that does not pass through the grates on the decks returns to be re-processed. Cleaning the material to be processed is another precaution.

The shape of the processed rock, whether cubic or lamellar, also needs to be evaluated.

In this video, we show a Furlan sieve in operation.

5. Pay attention to the sieve supplier

The mining equipment market offers different solutions. The quarry needs to be careful when making this choice.

Having experience with different projects is essential. Customizing the solution generates better results.

Care with the quality of the steel used in the production of machines and parts also accredits the supplier.

At this point, the history of the equipment supplier cannot be ignored. The durability of the equipment and the resistance of the replacement and wear castings guide the decision.

Otherwise, unexpected stoppages compromise the work.

This becomes very clear when monitoring plant data. Any gains made when purchasing machines and parts are illusory if, in operation, these items constantly fail.

Máquinas Furlan presents 2 models of screens for mining

Let's now talk about the Máquinas Furlan catalog, which features two models. Their main features are robustness and productivity. Ease of operation and maintenance are also present.

Furlan Vibrating Screens (PVA model) are recommended for washing and intermediate classification of minerals, sand, gravel and stone.

Technically, it is recommended when the minimum mesh size is 8 mesh, with material ranging from 2 to 6 mm. The models have 1 to 4 decks, and are equipped with a module. It is known as a conventional sieve.

When adopted in the final classification, the PVA model is the ideal solution for the final classification of fines passing through the 2mm screen.

However, for finer products, High Frequency Vibrating Screens (PVAF model) are the most suitable. They operate in a range of application granulometry in 100% dry materials below 2 mm.

It is used in the generation of sand, gravel and artificial sand. In addition to construction aggregates, it has gained space in the ceramics industry.

It is also used in the classification of materials for use as products classified as rock used in agribusiness.

The number of plants adopting PVAF has been growing. The verticality improves the efficiency of ultrafine classification. It also adapts to the different types of processed rocks.

PVAF is highly energy efficient, which reduces operating costs. In the case of Furlan, the model comes with adjustable electric or hydraulic vibrators, which, together with a low-amplitude, high-rotation frequency inverter, assist in classification.

They have 1 to 3 decks, or modules. A set of accessories allows effective control of the programmed slope. The equipment can also come with a metal structure, walkways, stairs and bottom and front discharge spouts.

We hope we have helped you choose the ideal sieve model. Now, let's schedule a meeting so that the Furlan team can evaluate your project and present the best solutions. Click here
