[0002] As a kind of equipment that relies on power difference to separate minerals, the working principle of electric separator is based on the unique electrical difference exhibited by mineral particles in the electric field. When these particles pass through the electric field generated by the electric separator, they will be subjected to different electric field forces due to their different electrical properties, thereby achieving effective separation. In the process of using electric separator to separate minerals, in order to improve the efficiency and accuracy of electric separation, the ore particles usually need to be preheated. This is because the moisture on the surface of the mineral particles not only changes its electrical conductivity, but also can cause small particles to adhere to each other, forming agglomerates, thereby reducing the electric separation effect. In order to improve the preheating efficiency, electromagnetic heating technology is gradually favored in the preheating and drying process of materials due to its rapid start-up and other characteristics. However, due to the complex and irregular shape of the ore particles, there are gaps between the particles, which leads to insufficient heating efficiency when using electromagnetic heating, and the heating of the ore particles is not uniform enough, thereby affecting the final electric separation effect.

After the metal particles and the ore particles fall from the upper hopper 4 onto the conveying belt 3, the conveying belt 3 conveys them from the first section to the end, the metal particles and the ore particles are scraped by the scraper 5 during the conveying process, so that the material height is prevented from being too thick, and the heating and drying of the ore particles are promoted.
