Grinding in mining gains momentum with ball and rod mills

Today we will discuss the use of ball and rod mills in the grinding stage of the mining industry. These devices are used to generate fine products and can work in an integrated manner.

Processing rocks under these conditions requires robust machines that also offer high performance. Maintenance stops need only be scheduled, which also requires reliable parts.

Stay with us and discover how the complete line of Máquinas Furlan, including accessories, offers these conditions, in addition to greater options for feeding the production line.

Reduce costs and increase productivity: the advantages of ball and rod mills

Ball and rod mills are used in the mining industry to obtain final products with fine grain size. The reduction in the size of the ore particles occurs through the rotation of the cylinder. Together, the steel balls or bars (metal body) impact the rocks, so that they reach the desired size.

During operation, the efficiency of the mills will be influenced by the size, quantity and type of coarse material. Performance also depends on the rotation speed of the equipment.

However, the entire process must be designed based on the hardness and moisture content of the ore in the plant. Another point to consider is how mobility fits into the overall flow of the plant.

The production of fines represents significant costs for quarries and mining companies, in items such as wear and tear on parts and energy efficiency. It also involves industrial safety, an example of which is dust control during operations.

Therefore, the choice of supplier is important. We are talking about highly operational machines that require rigorous maintenance to avoid unscheduled downtime.

Robust and sporty equipment in food: Furlan mills improve results

Máquinas Furlan has a portfolio with more than 150 different types of equipment used in the mining industry, including those in the grinding phase.

Rotary cylindrical mills are commonly used in mining and chemical plants, such as those that operate with silica, cement, gypsum, feldspar, coal, corundum, bauxite, among others. They operate in series or parallel, in open and/or closed circuits.

The ball mills, from the MB line, generate very fine granulometries, with a control mesh of up to 325 mesh (0.044 mm). They operate preferably in a closed circuit, in dry or wet mode, and integrate discharge arrangements in diaphragm overflow.

The bar models, from the MA line, normally perform coarser grinding, generally in stages that precede processing with ball mills. The control mesh operates between meshes 35 and 3 (0.5 to 6.7 mm, respectively). They operate in open circuit, in dry or wet mode and have overflow or peripheral discharges.

The Furlan line is manufactured with noble agents in special alloy steel or ceramic, depending on the application, which allows for robustness, durability and excellent performance. For this reason, it is known for being one of the most recommended in the mining equipment market, precisely because it combines superior results in fines with fewer maintenance stops.

Furlan also stands out in the market for offering an entire structure so that the customer can choose, among 4 different types of feeding, the one most suitable for their project - through conventional spout, parrot spout, direct feeding with dosing or drum.

In the case of direct feeding with dosing, the customer also has the option of purchasing accessories – such as metal silo, vibrating trough and screw conveyor – also from the Furlan brand.

In the metallic coating, another advantage for the Furlan customer

In addition, another advantage of Máquinas Furlan is the manufacturing of metal coatings, which can be an advantage for our customers when purchasing equipment with this type of coating. Find out more in this post .

So, it's time to evaluate the implementation of rotary cylindrical mills or plan to expand the results in the plant that is already running. You will see that one of Furlan's main differentiators is its experience in customer service, which generates the best solution.
