Factors affecting the working function of magnetic separator


Factors affecting the working function of magnetic separator:

1. Feeding speed and particle size. The speed of feeding should be in strict accordance with the design capacity of the equipment.However, it is very regrettable that the domestic magnetic separation equipment capacity generally marked on the high side.As for the particle size of materials, strictly speaking, a well-designed magnetic separation equipment can only be used for the separation of materials with relatively concentrated force distribution. It is inevitable that there will be no good results when a device is used to deal with materials with very large particle size difference.

2.Pulp concentration is one of the main factors affecting the magnetic separation effect of magnetic separator, mainly refers to the size of overflow concentration of classifier.
If the concentration of slurry is too high, the concentration of separation will seriously affect the quality of concentrate.Because at this time concentrate particles are easy to be fine gangue particles covered and wrapped separation is not open, together with the selection of grade reduction.Pulp concentration is too small that separation concentration is too low, and will cause the flow rate increased between the election do not shorten, so that some should have the opportunity to come up the fine magnetic particles, into the tailings grade increase, resulting in losses.Therefore, pulp concentration should be adjusted according to the need.

3. Whether the magnetic field force provided by the magnetic source of the magnetic separator is appropriate.We all know that after magnetic objects enter the magnetic field, the force depends on the size of the magnetic field force at the point, and the size of the magnetic field force not only depends on the height of the magnetic field, but also has a close relationship with the magnetic field gradient at the point.It is obviously a very simple mistake to blindly pursue high magnetic field intensity and ignore the construction of magnetic field gradient.However, most of the domestic magnetic separation manufacturers in the magnetic source design is not fully considered, which directly leads to low energy magnetic separation equipment.

4, the dressing equipment magnetic separator itself to provide a reasonable way of unloading, that is, when the magnetic field to capture the magnetic material is cleaned up in time to not affect the magnetic field of the next time to capture the ability.

5. Whether the movement state of materials in the magnetic separation process is conducive to magnetic capture.

6. Other external factors, such as the magnetic separator maintenance is not timely, technical personnel is not professional.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
