electrostatic separator


The high voltage electric separator is a type of electromagnetic separator equipment used in electric mineral processing. It utilizes the differences in electrical properties of minerals and materials to separate them. There are various types of electric separator equipment, including high voltage electric separator, plate type electric separator, double roll electric separator, and three drum type high voltage electric separator. By taking advantage of the different electrical properties of minerals, electromagnetic separators can effectively separate minerals such as magnetite, ilmenite, cassiterite, and natural gold, which have good conductivity, from minerals such as quartz, zircon, feldspar, calcite, scheelite, and silicate minerals, which have poor conductivity.

Working principle:

The high voltage electric separator applies a certain intensity of high-voltage electricity to create a corona electric field between the corona electrode and the drum. At the same time, an electrostatic field is formed between the bias electrode and the drum. After the minerals are dried and heated in modern mineral processing, they enter the corona electric field with the help of a blower. The corona current charges all the minerals and allows conductive mineral particles to quickly transfer to the drum, a process known as discharge. As the minerals leave the corona electric field and roll into the electrostatic field, the positive charge on the surface of the drum promotes the conductive minerals to become positively charged. These conductive minerals will then fall from the front of the drum to the conductive product under the influence of electricity, gravity, and centrifugal force. Non-conductive minerals, on the other hand, retain negative charges on their surface due to slow discharge, resulting in a greater electrostatic attraction in the electrostatic field. These minerals continue to adsorb on the surface of the drum until they are brushed off from behind the drum, achieving the goal of separating minerals based on their conductivity.


The electromagnetic separator utilizes the difference in material conductivity to separate materials under the influence of electric and mechanical forces in a composite electric field that combines high-voltage corona electric field and high-voltage electrostatic field. This technology enhances the attraction of the electrostatic pole to conductive materials and the repulsive force to non-conductive materials. The invention of the corona electric separator has played a crucial role in the widespread adoption of electromagnetic separators in various fields. This is because high voltage electric separator equipment (electromagnetic separator) has higher efficiency compared to previous electrostatic beneficiation equipment. Most high voltage electric separator equipment (electromagnetic separator) used in production and laboratory settings utilize a composite electric field that combines corona and electrostatic fields.
