Brief Introduction

Rotary dryer is mainly used in the fields of building materials, mineral processing, metallurgy, chemical industry, etc., it can be used to dry materials with specified moisture and size.

Working Principle

After the ore slurry flows into the tank body through the ore feeding box, under the action of the water flow of the ore feeding water spray pipe, the ore particles enter the ore feeding area of the tank body in a loose state. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a “magnetic cluster” or “magnetic chain”. .

Since the polarities of the magnetic poles are alternately arranged along the rotation direction of the cylinder and are fixed during operation, when the “magnetic group” or “magnetic chain” rotates with the cylinder, a magnetic stirring phenomenon occurs due to the alternation of the magnetic poles, and is mixed with The non-magnetic minerals such as gangue in the “magnetic group” or “magnetic chain” fall off during the turning, and the “magnetic group” or “magnetic lotus” that is attracted to the surface of the cylinder is the concentrate.

The concentrate is transferred to the edge of the magnetic system with the cylinder where the magnetic force is weak, and is discharged into the concentrate tank under the action of the flushing water flow from the discharge pipe. Non-magnetic or weakly magnetic minerals are left in the pulp and discharged out of the tank with the pulp, that is, tailings. This is the basic working principle of the magnetic separator.

Performance and Advantages

The dry magnetic separator is a magnetic beneficiation machine for the separation of dry magnetic minerals. Compared with the wet magnetic separator, which uses liquid as a diluent to improve the separation efficiency, the dry magnetic separator is required to be When the sorted minerals are dry, the particles can move freely and form an independent free state. Otherwise, the magnetic separation effect will be affected, and some will cause unsortable consequences.

According to the magnetic rate of different minerals, abide by the concept of greater recycling, use domestic high-performance magnetic materials, and use professional magnetic focusing principle design to achieve the best sorting effect in China at present, which can effectively reduce production costs for enterprises, Reduce consumption and maximize the economic benefits of the concentrator.

Application Area

There are many minerals that can be separated by the magnetic separator, such as: magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate ore, metallurgical manganese ore, manganese oxide ore, iron placer, Kaolin, rare earth minerals, etc. can be sorted by magnetic separator.
