Eficiência em Moagem: Como os Moinhos de Bolas Impulsionam a Produção Mineral

Grinding Efficiency: How Ball Mills Boost Mineral Production

The Minerando blog discusses the ball mill in this post. The equipment is used in mining plants that generate products with fine grain sizes, intended to be raw materials for other industrial processes.

It is used in operations involving iron ore, cement and gold extraction, among others. Efficiency in this process ensures productivity and cost reduction.

Due to its high-performance and durable equipment, Máquinas Furlan also stands out in the grinding segment, being one of the main suppliers of ball mills for the mining sector.

Another difference for Furlan is its diversified portfolio, which includes different types of equipment, allowing it to offer complete solutions to customers.

So, stay with us until the end and find out more.

Fine granulometry marks the products generated by ball mills

The ball mill is one of the equipment used in mining plants that seek reduced particle sizes in their products. Some of the main components of this machine include the rotating cylinder, internal lining and grinding balls.

It is commonly used when the previous grinding steps do not achieve the desired rock grain size.

Whether in wet or dry processes, operators often praise these machines' ability to process large volumes of material.

Generally, milling in this scenario is marked by efficiency, an important factor in industries seeking productivity and reducing operating costs.

This efficiency results from the balance of factors in the machine's operation, such as the feed rate, rotation speed and the quantity and size of the grinding balls.

When deciding on machine configuration, companies need to consider the different types of internal linings. Cylinder lining materials should be chosen based on the operating conditions and the type of rock to be ground.

Ball mills with performance and durability? The brand is Furlan

Furlan Machines' Ball Mills (MB) can be used as individual equipment or integrated into complete plant projects. They are the ideal solution due to their robustness and excellent performance in low particle sizes.

Furlan uses special alloy steels in its manufacturing process, which increases durability. Ease of operation and maintenance is the result of equipment that has been improved over time, with different capacity configurations according to the customer's wishes.

The choice of model depends on the information that the mining company provides to Furlan, such as the type of material processed and the desired production. See the equipment in operation in this video.



Very fine granulometries adopt a control mesh of up to 325 mesh (0.044 mm). This type of mill commonly generates raw material for other final products.

Cement plants, mining plants and chemical industries use the process to grind cement, gypsum, silica, feldspar, coal, corundum and bauxite. Gold mining is also on the list. Furlan has also developed models for agribusiness, such as agricultural limestone.

Typically, the plant operates in a closed circuit, either dry or wet. The discharge arrangements can be of the overflow or diaphragm types.

The optional features stand out for their versatility in feeding. There are four systems available, which allows the equipment to be easily adapted to different installations. These include the conventional or parrot spout, the drum and the direct feeding system with specific dosage for dry processing.

This is only possible due to the working format adopted by Furlan. The company concentrates the production of machines and parts in its Limeira (SP) unit. The company's own foundry confirms the quality of the steels used in the projects.

It also features a catalog with over 150 types of equipment, including rod mills – machines that are often recommended for projects involving ball milling. The mill can also be manufactured by Furlan with a metal coating.

Therefore, the best choice for a rock processing machine has a name: Furlan, which combines tradition in supplying mining – with 63 years in the market – and innovation in products and services.

Add to all this an Engineering team that is always ready to offer the best options, depending on the client's project.
