Iron ore particle removal system for vertical magnetic separator
The patent application (Publication Number: US20240024894A1) describes a system and method for removing iron ore particles attached to a magnetic matrix in a vertical magnetic separator. The system includes a separation ring with a magnetic matrix, an ore feed inlet, an ore accumulation vessel, a magnetic field-generating device, collecting trays, a demagnetizer, a mechanical cleaning device, and compressed air jet-generating devices. The method involves demagnetizing iron ore particles, scraping the magnetic matrix with a mechanical cleaning device, and applying compressed air jets to remove the particles.
The system described in the patent application can be used in a vertically pulsating high gradient magnetic separator (VPHGMS) and includes features such as multiple collecting trays, a mechanical cleaning device with flexible filaments, and compressed air jet-generating devices positioned strategically for effective particle removal. The method outlined involves a series of steps including demagnetizing, scraping, and applying compressed air to efficiently remove iron ore particles from the magnetic matrix. The use of a demagnetizer with coils of enameled copper wire in a Helmholtz configuration and the application of compressed air in an angled manner are key aspects of the system and method for effective particle removal in the vertical magnetic separator.
