Magnetic separator can be divided into low magnetic field intensity magnetic separator, the magnetic separator, high magnetic separator; generating a magnetic field in accordance with a method can be divided into electromagnetic and permanent magnetic separator
Magnetic separator; accordance with the structure can be divided into different disc, drum, roller, ring, drum, transfer cage and belt magnetic separator; sorting methods can be divided by the dry and wet
Magnetic separator.
Can be divided into suspension magnets downstream magnetic separator and semi-countercurrent separator:
Downstream permanent magnet drum magnetic separator, the slurry moving direction or the direction of rotation of the cylindrical products moving in the same direction. Slurry from the tank to the mine directly into the cylinder below the magnetic system
Non-magnetic mineral particles and the magnetic mineral particles weak bottom by a cylindrical gap between the bottom two discharge. Magnetic mineral particles stick on the cylinder surface, the cylinder rotates together with the magnetic
Department at the edge of the magnetic field is weak, the mine water discharge be landed to concentrate tank. Downstream magnetic machine structure is simple, processing capacity, can be used more than one series, suitable for
Choice of granularity is 6 ~ 0mm strong magnetic ore coarse roughing and operations, or for the recovery of the magnetic heavy media. Semi-countercurrent permanent magnet drum magnetic separator, to ore slurry is
A loosely suspended from the bottom of the tank into the separation space, pulp movement direction and the direction of the magnetic force is basically the same, so the mineral particles can reach very high magnetic forces round
Cylinder surface. N52 magnet In addition, the tailings from the tailings discharge hole on the bottom, so that the height of the overflow surface can be maintained in the slurry tank level. The above two features, must
Given half a counterflow separator to receive a higher quality of concentrate and metal recovery. It is widely and to handle micro-fine (less than 0.2mm) thick ferromagnetic ore
Selection and selection operations. This separator can be more than one series, and raise the concentrate grade.

using the method of permanent lifting
Permanent lifting lifting process mainly used for holding iron material plate-shaped or cylindrical workpiece, with a compact structure, convenient operation, strong retention, safety and reliability
Features, will help improve N52 magnet labor efficiency, so in factories, docks, warehouses and transportation industry, has been widely used as a lifting tool. In order to regulate Wing
Magnetic lifters correct way to use the following brief overview:
1, permanent lifting must be used within the rated lifting, non-overloading, to prevent accidents.
2, by lifting the workpiece thickness and surface quality will affect the permanent lifting of the lifting capacity so before use, see performance curves, and then to determine lifting
The actual lifting capacity.
3, the workpiece material on the lifting of the lifting capacity, but on a low carbon steel workpiece lifting capacity taken as 100%, compared to 95% of the steel workpiece, high carbon steel workpiece
90% and 75% of low-alloy steel, cast iron, compared to 50%.
4, rotation of the handle mounting, should permanent lifting placed on the plate, so that the through magnetic magnetic lifter case of turning the handle freely, otherwise
That are difficult to use great force by turning the handle.
5, lifting the workpiece, the workpiece should magnetic lifter placed center of gravity position, and then move the handle from the release position to the suction holding position, the handle of the sliding key is checked
Whether it is locating pin lock, in recognition of the handle has been pinned, can the lifting.
6, For lifting cylindrical workpieces, should magnetic lifter V-groove bottom in contact with the workpiece, but the lifting capacity is generally rated lifting capacity of 30-50%
.
7, lifting the workpiece, it should lift the top of the button under the handle, the handle of the sliding key with locating pin out, and then reset the release lever handle position, so lifting at
In the closed state, and finally remove the jack.
8, permanent lifting using environmental conditions:
An ambient temperature less than 80 degrees Celsius
(2) No severe vibration and shock
3 surrounding medium non-corrosive metal etchant
