Electromagnetic dry powder magnetic separator is a device that uses
electromagnetic force to separate materials with different magnetic properties,
mainly used for processing dry powdered materials. Its working principle is as
follows:
1. Material feeding:
Dry powder materials are uniformly fed into the feeding port of the magnetic
separator through a vibrating feeder or belt conveyor, and enter the sorting
area.
2. Magnetic field effect:
In the sorting area, the electromagnetic dry powder magnetic separator
generates a strong electromagnetic field. Electromagnetic coils generate a
magnetic field through current, and the strength of the magnetic field can be
adjusted as needed.
3. Sorting process:
When the material enters the sorting area, a mixture containing magnetic and
non-magnetic minerals begins to separate under the action of the electromagnetic
field. Magnetic minerals are attracted by magnetic force, move along the
direction of the magnetic field, and attach to the magnetic medium of the
magnetic separator, such as magnetic rollers or plates.
4. Discharge of non-magnetic materials:
Non magnetic materials, due to their lack of magnetic force or low magnetic
force, rely on gravity or other mechanical forces to continue moving along their
original path and ultimately be discharged from the non-magnetic material outlet
of the machine.
5. Collection of magnetic materials:
The magnetic material adsorbed on the magnetic medium rotates or moves with
the magnetic medium. After leaving the magnetic field area, due to the loss of
magnetic force, the magnetic material falls off and is discharged from the
magnetic material outlet, completing the separation process.
6. Cyclic operation:
The magnetic medium of the electromagnetic dry powder magnetic separator
works continuously in the separation zone, completing the sorting of a batch of
materials, and then processing the next batch of materials to achieve continuous
operation.
###Equipment structure and configuration
-Electromagnetic coil: The core component that generates a magnetic field,
and the strength and range of the magnetic field are determined by the strength
of the current and the design of the coil.
-Magnetic medium: used to capture and carry magnetic materials, commonly
including magnetic rollers, magnetic plates, etc.
-Feeding system: Ensure that materials enter the sorting area evenly, usually
using a vibrating feeder or belt conveyor.
-Discharge system: The separated magnetic and non-magnetic materials are
discharged separately, usually with two outlets.
###Application field
Electromagnetic dry powder magnetic separators are widely used in mining,
metallurgy, chemical, building materials and other industries, for the
separation and purification of dry powder materials such as iron ore, ilmenite,
manganese ore, quartz sand, etc. Its advantages lie in its ability to handle dry
materials, good sorting effect, simple operation, and strong adaptability.
###Advantages
-Good sorting effect: high magnetic field strength, high sorting accuracy,
and can effectively separate small magnetic materials.
-Easy to operate: The structure is simple, and the operation and maintenance
are convenient.
-Strong adaptability: suitable for sorting various dry powder materials,
especially for extracting high-purity materials.
By optimizing the parameters and operating procedures of the electromagnetic
dry powder magnetic separator, the sorting efficiency and product purity can be
significantly improved, meeting the needs of different industrial fields.
