Magnetic separator

Application:

Magnetic separator equipment is widely used in various industries such as waste recycling, wood industry, coal industry, kiln industry, organic chemistry, and food factories. It is used to separate and remove magnetic materials from raw materials such as Hematite, Pyrrhotite, Peishao ore, and Ilmenite with a particle size distribution of less than 3 mm. It is also used for iron removal in raw materials such as coal, mining enterprises, and decorative building materials. It is considered one of the most widely used and practical models in the industry. Magnetic separator equipment finds applications in coal, wood, kiln, organic chemistry, food, and other fields. In the coal industry, wet or flat magnetic separators are used for materials such as manganese ore, Hematite, Pyrrhotite, Peishao ore, Ilmenite, hematite Limonite with a particle size distribution below 50 mm. They are also used for iron removal in raw materials such as coal, mining enterprises, and decorative building materials.

Equipment classification:

Magnetic separator equipment can be divided into two categories. The magnetic system of rare earth permanent magnetic separators is mostly made of high-quality Ferrite core raw materials or composites with rare earth magnetic tiles. In earlier cases, the average magnetic flux on the surface of the magnetic cylinder of magnetic separator equipment was 80-400MT. With the continuous development of technology, it is now possible to make it into a roller shape, and the magnetization intensity has also increased to 1650MT, which is currently the highest magnetization intensity.

Working principle:

A magnetic separator is a machine used to remove magnetic materials from powder-like particles. When the coal slurry is injected into the acid washing tank through the ore feeding box, the loose ore particles enter the acid washing tank under the water flow effect of the water spraying pipe head. In the presence of electromagnetic fields, magnetic particles agglomerate and form magnetic clusters. These magnetic clusters are attracted to the drum due to the magnetic effect in the coal slurry. As the drum rotates, the magnetic clusters or lumps adhere to the surface of the drum. Non-magnetic minerals such as gangue that are mixed in the magnetic clusters or lumps fall off during rolling. Finally, the titanium concentrate is obtained from the magnetic clusters or lumps that adhere to the surface of the drum.
