Exploring New Frontiers in Ore Filtration: Introducing the BRASFELT Pilot Plant At the forefront of innovation in mineral filtration, BRASFELT presents one of its projects: the BRASFELT Pilot Plant. Developed as a versatile and effective solution for pilot-scale filtration of iron ores, non-ferrous ores and other materials, this pilot plant represents a significant breakthrough in the field of filtration technology. Using Vacuum Disc Filter technology, with a filter area of 40m², which allows to achieve production capacity of up to 120 tons per hour, the BRASFELT Pilot Plant offers a range of applications in mining. From its use in small scale plants to define solid-liquid separation processes to its application as a practical and compact solution for miners with lower demands, this pilot plant is truly versatile and effective. An important milestone in this journey of innovation was its first deployment in one of the largest iron mining companies in Minas Gerais. During a period of 24 months, the BRASFELT Pilot Plant was leased and used for tests in the treatment of flotation tailings of iron ore, in order to define dry disposal processes (Dry Stacking). This pioneering experience has demonstrated not only the effectiveness of technology, but also its potential to transform industrial practices and collaborate on environmental sustainability. BRASFELT is committed to continuing to drive innovations in ore filtration. With the BRASFELT Pilot Plant, we are prepared to lead the way towards a more efficient, sustainable and responsible future for the mining industry.

Brasfelt Ltda, the national leader in solid/liquid separation in mining, recently completed the supply of four 120 m² vacuum disc filters for a large mining company located in Espírito Santo. With more than 30 years of experience in the market, BRASFELT offers complete solutions for the filtration of concentrates and tailings treatment, from the conceptual design to the supply of the equipment and peripherals involved. The filters provided by BRASFELT have advanced filtering technology, generating operational gains, with greater physical availability, lower operating cost and higher production per filter area. In addition, these filters incorporate technologies to protect abrasive wear, combined with the reliability of Brasfelt products.

As part of this special tailings edition, International Mining Editorial Director Paul Moore talked to Eustaquio Barbosa , Director of Operations at Brasfelt Ltda , based in #BeloHorizonte , Brazil. #Brasfelt manufactures equipment for solid/liquid separation and is the leader in the Brazilian market in #vacuum disc filtration for #ironore while also continuously developing products and solutions for the #filtration of other mined products as well as offering filtration solutions for other industries. Barbosa told IM: "Brasfelt emerged in 1993 as a reseller of filter fabrics and other products produced by Tamfelt Oy, a Finnish company. The business evolved naturally and, due to a lack of local production, started a cooperation with a Norwegian company called Hydralift. Brasfelt then acquired the rights to produce vacuum #discfilters locally, which became the first ones produced in Brazil and were first sold to Vale ’s Kobrasco plant, part of its Tubarão operations, in 1998. After that, Brasfelt modified its solutions and offering so that it could best fulfil the necessities of the local market, including the right price level. The result is that today Brasfelt filters are stronger and allow for higher production and longer operation cycles, consequently decreasing the costs of operation and maintenance. Therefore, Vale and other companies started to acquire Brasfelt filters in Brazil and in Chile, so that Brasfelt became a market leader in those countries." He adds on why disc filters are so suited to Brazilian iron ore tailings #dewatering : "The choice of a filter depends on multiple factors, but one of them is the size of the solid particles. For extremely fine materials, the natural choice is filter presses. But for not so fine particles, the natural choice is disc filters. The main operational difference between them, is that filter presses do not have a continuous cycle (they operates in batches) and also the productivity (tonnes per hour per square meter) is lower than that of disc filters. So the use of disc filters in iron ore tailings, which requires high production, was a break in the paradigm that stated disc filters are not suitable for this application. The content of sand really affects how the equipment will perform. Due to this challenge, Brasfelt made some innovations in its disc filters, such as the application of ceramic lining in more vulnerable parts and replacing the filtrate tubes from HDPE (High Density Polyethylene) to polyurethane. These innovations allowed the equipment to be resistant to the sand content of the #tailings ." #futureofmining #tailingsmanagement #futureoftailings #tailingsdewatering

Brasfelt, aiming to raise technical quality and answer doubts of its customers, received, on February 7, the visit of the technical team of CMP - Compañía Minera del Pacífico S.A.

Seeking to improve and optimize the filtration processes, Brasfelt Ltda has developed a head with removable top for the vacuum disc filters. This head makes it possible to change only the top (bottom of the head) that is the zone most affected by wear during the operation of the vacuum disc filter. This option allows inspection and maintenance of the equipment more quickly, as well as ensuring lower maintenance cost, since it allows only the most worn item to be replaced. Benefits of the removable top head: Enables faster and safer maintenance; Lowers maintenance cost with raw material and labor. Brasfelt is always investing in innovation and development of its products.

For the filtration simulation with Vacuum Disc Filters, Brasfelt performs the bench test called Leaf-Test . This methodology can reliably represent what happens with Vacuum Disc Filters in industrial filtration. Interested companies can send the samples to be filtered to our headquarters in order to carry out this procedure. Recently, we also developed the Leaf-Test Portable, which consists of taking this equipment to the customer, in a compact way, to perform the test in its dependencies. Thus, with the execution of the Leaf-Test, we were able to find and define the best filtering conditions for Vacuum Disc Filters. Leaf-Test allows simulating the main variables that may occur in the field, such as: Rotation speed of the filter; filter fabrics; training and drying time; pressure and vacuum flow variation; variation in pulp densities; Use of auxiliary filtration reagents.

The treatment of tailings is the ideal and economically viable solution for the replacement of the use of dams, besides enabling the recovery of existing residual ore. Recently, Brasfelt Ltda provided 14 Vacuum Disc Filters for a large iron mining of Minas Gerais, with 140m² of filter area per filter, for tailings filtration. With 30 years of experience in the filtration and Vacuum Disc Filter market, BRASFELT offers complete solutions for the treatment of tailings, ranging from conceptual design to the supply of equipment and peripherals involved in the process. The dry disposal of the treated waste allows the reuse of the pits, increases the recovery of water in mineral processing and, in some cases, the marketing of waste as a by-product, in addition to avoiding the risks inherent in dams.

Brasfelt Ltda presents the NT21 EASY POWER SOLUTION device, which was developed to assist the maintenance of disc filters, when there is a need for repositioning the main axis (tree). This device allows this activity to no longer be performed manually and favors routine maintenance, such as changing bags and sectors, with absolute safety. The NT21 is designed to run on a low-power pneumatic motor using the customer service compressed air line. The pneumatic motor can be easily blocked instantly by simply closing the quick-release valve on the panel accompanying the equipment. Easy to install, no filter intervention is required. Brasfelt Ltda sells the NT21, also installing it in filters that are already in operation. The NT21 can be integrated into new equipment, thus facilitating the maintenance of filtration. We are available for clarification and technical visits.

Revitalization of vacuum disc filters and good maintenance practices.

Seeking to improve and optimize more and more processes in Vacuum Disc Filtration, Brasfelt developed the Head with Variable Formation Zone. This head allows a variation in the formation zone of the cake, without disassembly of the head, allowing the operator to instantly define the time of formation depending on the characteristic of the material to be filtered. This variation allows an instant control of the thickness of the pie and as a consequence better control of moisture and production. Brasfelt Variable Forming Angle Vacuum Inlet Head - Patent PI0705919-1 The Variable Forming Angle Vacuum Inlet Head is an item patented by Brasfelt. Brasfelt Ltda is always looking to improve and develop new products. Benefits of the Variable Head: -Allows direct, fast and objective action, without disassembly of the equipment. -Change in training time without changing the drying time. -Change in the formation time without changing the rotation speed of the filter.

In order to expand the knowledge of the operation, maintenance and process teams of our customers, Brasfelt Ltda held on Monday, 07/24/2023 a workshop for operation and maintenance of BRASFELT vacuum disc filters. In order to answer the doubts of professionals, this training addresses in a didactic and objective way the vacuum filtration process and the good practices that must be adopted during the operation and maintenance of the disc filters to ensure a high production, with quality and reliability. Being of interest, Brasfelt Ltda leaves its communication channels open for future scheduling, this and other training that its specialized team is able to offer.

Due to its high productivity and low operating cost, the Disc Filter is used on a large scale in the mineral filtration process. The discs are divided into Sectors, whose function is to support the filter elements that make solid-liquid separation, in addition to conducting the filtered liquid to the collector tubes. Brasfelt Ltda has several models of sectors in its product catalog, especially the BRASEC0906 for 9 feet Disc Filters and the BRASEC0636 for 6 feet Disc Filters.

Brasfelt Ltda invests in the evolution of its team, providing excellent service to its partners and customers. Last June, the training on Ore Treatment was carried out by Eng.

Brasfelt Filter Press - Maintenance and Operation Training

Air Lung Tanks Brasfelt The Air Lung Tanks have the fundamental role of keeping the pressure and volume of compressed air stable so that you have an efficient blow and that allows the complete discharge of the pie.

The importance of blowing regulation in Vertical Vacuum Disc Filters.  The filter operating cycle ends with the cake unloading, which is done by means of a “blow” of compressed air, in a short period of time, with an approximate pressure of 1.0 to 2.0 bar. The blow occurs with the magnetic signal generated by the approximation between the sensor and the indicator bumps in the center of each filtrate tube. The correct adjustment of the moment of blowing causes the detachment of the cake to occur in the correct position in relation to the deflector plate and the discharge box, also preventing the filtering element from touching the edge of the box or the deflector plate at the time of discharge. The correct adjustment of the blowing, maintains the synchronization of the sensor and the blowing collar, which must be done, in a BRASFELT filter of 8'10", according to the following steps: 1st step (FIGURE 1) - Assemble the position collar on the drive hub (in some models the position indicators are fixed directly on the main shaft transition hub), according to the positioning indicated in the figures below. 2nd step (FIGURE 2) - Assemble the sensor and sensors fixation support according to the positioning indicated in the figures below.

Technical and commercial cooperation agreement Fraccaroli & Balzan Brasfelt Ltda, a national leader in filtration systems based in Belo Horizonte, and Fraccaroli & Balzan, a traditional filter press manufacturer based in the city of Verona, Italy, announce to the market that they have entered into a technical and commercial cooperation agreement to supply press filters in Brazil. The union of these two companies will bring to the Brazilian market the best technologies and solutions for solid-liquid separation systems in which the use of filter presses is indicated, in mineral processing, waste recovery and effluent treatment plants installed in Brazil.
