1 / 7 Automatic Continuous Flow Magnetic Separator - Field of Invention

[01] The present invention relates to the field of industrial magnetic separation equipment, more specifically to an automatic continuous flow magnetic separator intended for the removal of ferromagnetic metallic particles present in granular or powdered materials, such as grains, cereals, flours, industrial powders and the like, transported in channel or pipeline systems.

[02] More particularly, the invention describes a self-cleaning magnetic separator equipped with rotating magnetic elements arranged in a circular structure, configured to operate continuously in industrial processing lines without interrupting the material flow. The system uses high-intensity permanent magnets, preferably based on neodymium-ironboron (Nd2FeI4B), positioned on a rotating plate protected by non-magnetic material walls, in order to allow the efficient capture of metallic contaminants present in the product flow and their automatic disposal in a specific removal zone.

[03] The invention finds preferential application in industrial grain processing plants, mills, extruders, food processing lines, pneumatic or gravitational material transport systems and storage units, being intended to protect equipment against damage caused by the presence of metallic objects in the production flow, as well as to increase the operational reliability and safety of industrial assets. Petition 870260039720, dated 04 / 29 / 2026, page 8 / 26 2 / 7 BACKGROUND OF THE INVENTION

[04] The presence of metallic particles in granular or powdered material streams is a recurring problem in various processing industries, especially in the grain, food, feed, mining and chemical processing sectors. During the transport, storage, grinding, extrusion and beneficiation stages, it is common for metallic contaminants, such as screws, tool fragments, wires or steel filings, to be inadvertently introduced into the product stream. These contaminants can cause serious damage to industrial equipment, as well as compromise the quality of the final product and generate high operating costs resulting from unscheduled shutdowns and corrective maintenance.

[05] In order to mitigate these problems, several magnetic separation systems have been developed and are widely used in industrial processing lines. Among the most common devices are tubular grid magnetic separators, fixed magnetic plates and magnetic boxes installed in ducts or channels for transporting materials. These devices use high-intensity permanent magnets to attract and retain ferromagnetic particles present in the product flow, preventing such contaminants from advancing to later stages of the production process.

[06] However, conventional magnetic separators have significant operational limitations. In many systems, the magnetic elements remain fixed inside the material flow, gradually accumulating metallic particles over time. This accumulation progressively reduces the capture efficiency of the magnets. Petition 870260039720, dated April 29, 2026, page 9 / 26 3 / 7 and requires the periodic execution of manual or automated cleaning procedures, which often demand the interruption of the production flow. In high-productivity industrial environments, such interruptions can result in significant losses of efficiency and increased operating costs.

[07] Some solutions available in the state of the art seek to circumvent this problem by means of self-cleaning systems based on movable magnetic grids. In these systems, the magnetic elements are temporarily displaced out of the product flow to allow the removal of adhered contaminants. However, during this cleaning interval, the material flow remains momentarily unprotected, allowing the passage of uncaptured metallic particles. In addition, the prolonged accumulation of contaminants on the magnetic elements can cause unexpected detachments of these particles, allowing them to return to the material flow and compromise the integrity of downstream equipment.

[08] Given these limitations, the need for more efficient solutions that allow the continuous separation of metallic contaminants without interrupting the production flow and without temporary loss of system protection becomes evident. In this context, the need arises to develop an automatic magnetic separator capable of operating continuously, simultaneously capturing and removing metallic contaminants, while maintaining high separation efficiency and greater operational safety for sensitive industrial equipment, such as mills, extruders, conveyor systems and grain processing units. SUMMARY OF THE INVENTION Petition 870260039720, dated 04 / 29 / 2026, page 10 / 26 4 / 7

[09] The present invention relates to an automatic continuous flow magnetic separator, specially developed to promote the efficient removal of metallic particles present in granular or particulate materials in industrial processes, operating in a continuous and automated manner.

[010] The objective of the present invention is to provide equipment capable of performing magnetic separation without interrupting the flow of material, eliminating the need for stops for manual cleaning and increasing process productivity.

[011] A characteristic of the present invention is a magnetic separator comprising a base structure equipped with a material entry point, a clean product exit point and a metallic waste exit point, the latter being associated with a collection tray, allowing efficient segregation of the removed contaminants.

[012] It is also characteristic of the present invention the arrangement of a rotating assembly composed of support discs fitted with magnets, preferably neodymium magnets, mounted on a shaft driven by a geared motor, such assembly being configured to capture metallic particles during the movement of the material inside the equipment.

[013] Also characteristic of the present invention is the presence of internal divisions in the base structure, intended for the individualized positioning of the magnetic discs, associated with elements for protection and direction of the flux, in order to optimize separation efficiency and avoid material dispersion.

[014] Additionally, a characteristic of the present invention is the incorporation of a scraper disposed internally near the waste outlet point, configured to promote the continuous removal of Petition 870260039720, dated 04 / 29 / 2026, page 11 / 26 5 / 7 metallic materials adhered to the magnets, ensuring the automatic discharge of waste without the need for external intervention.

[015] It is also characteristic of the present invention that the equipment is integrated into the production process, operating in a synchronized manner with the material flow, with automatic activation and continuous operation, guaranteeing high operational efficiency.

[016] As advantages, the present invention provides increased final product quality, reduced contamination by metallic particles, protection of subsequent equipment, reduced operating costs for maintenance and cleaning, as well as greater reliability and performance in continuous industrial processes.

[025] The automatic continuous flow magnetic separator, object of the present invention, comprises a base structure (10) provided with an inlet point (11), a waste outlet point (12), associated Petition 870260039720, dated 04 / 29 / 2026, page 12 / 26 6 / 7 to a collection tray (121), an external closing lid (13) and a clean product outlet point (16).

[026] The base structure (10) has, on one of its lateral faces, a support (14) intended for the positioning of a geared motor (20), which is responsible for driving a shaft (21) to which support discs (30) equipped with magnets (31) are integrally mounted.

[027] The magnets (31), preferably made of neodymium, are arranged next to the support discs (30) in order to enable the efficient capture of metallic particles present in the material flow, promoting their conduction to the waste outlet point (12), where the discharge of said waste occurs, without the need for prolonged retention or manual intervention for cleaning.

[028] Internally, the base structure (10) has divisions (15) configured for the individualized positioning of the support discs (30) with magnets (31), each division (15) being provided with a protection (151), which acts in containing and directing the flow of material, as well as in protecting the internal components.

[029] Additionally, the structure (10) comprises a scraper (17), disposed internally and positioned adjacent to the waste outlet point (12) and the divisions (15), said scraper (17) being configured to promote the removal of metallic waste adhered to the magnets (31), ensuring their continuous and efficient release to said outlet point (12).

[030] As illustrated in Figures 7 and 8, the scraper (17) is strategically positioned next to the divisions (15), following the path of the discs (30), in order to ensure the effective removal of the residues captured along the rotational movement. Petition 870260039720, dated 04 / 29 / 2026, page 13 / 26 7 / 7

[031] The support discs (30), equipped with magnets (31), are mounted inside the structure (10), aligned with the respective divisions (15), being coupled to the shaft (21), which is driven by the geared motor (20), so that the drive of the motor promotes the continuous rotary movement of the discs (30), enabling the continuous flow magnetic separation process.

[032] The equipment is operated in an integrated manner with the production process, being activated simultaneously with the start of the material flow and switched off at the end of the operation, ensuring synchronized and efficient operation.

[033] It is important to highlight that the constructive configuration of the automatic continuous flow magnetic separator allows for high efficiency in the removal of metallic particles, significantly reducing contamination of the final product and contributing to increased quality of the processed material, as well as protecting subsequent equipment in the production line.

[034] Additionally, the arrangement of the magnetic discs (30), associated with the use of high intensity magnets (31) and the continuous scraping system (17), gives the equipment autonomous operation, with low maintenance requirements and high operational reliability, making it especially suitable for industrial applications that demand continuous processing and high performance in the separation of metallic contaminants.
