Dry magnetic separator works

Dry magnetic separator works:
After the material through electromagnetic vibrating feeder evenly to the sorting area, drag the bottom of the belt into the sorting uniform magnetic roller, due to the non-magnetic material particles from the magnetic force, the centrifugal force and gravity, non-automatic fall magnetic products connected trough. The magnetic particles is due to strong magnetic attraction, adhered to the separation of the magnetic roller belt surface, after the sorting belt to fall away from the magnetic roll separators products connected trough area in order to achieve the magnetic and non-magnetic materials separation.

Dry drum magnetic separator maintenance

Dry drum magnetic separator maintenance:
1. Wet drum separator should be full-time staff to check and installation.
2. equipment installed in the concrete foundation level, and with the anchor bolts.
3. The installation should pay attention to the main body vertical and horizontal.
4. Press the power configuration of the device power cord and control switches.
5. Check is completed, the empty load test, test the normal production.

Magnetic separator block after installation is complete mineral sorting test

For most ores, the degree of separation marks ore monomer that is the size of the magnetic particles and gangue mineral particle separation of coarse or fine ore particle size.
If the ore to a small particle size, indicating a high degree of mineral monomer separation, can be satisfied with the sorting index; if given the relatively coarse ore particle size, mineral did not fully explain dissociation, monomer separation is not high, opposite the living body more That magnetism
Particles and gangue is still considerable parts together. Because of the living body also has a considerable magnetic sorting can choose up to a considerable part of that lower grade ore. Therefore, the requirements for the mineral magnetic separator for silica sand must be sufficiently achieved monomer separation.
For coarse-grained disseminated ore and gangue minerals as long as reached monomer separation on the line, not necessarily the size too small. Such ore sometimes coarse granularity although some, but not low quality sorting, the main reason is due to ore dissemination size
Coarse grinding to a certain extent useful minerals and gangue separated.

Wet magnetic separator Guide

Wet magnetic separation of magnetite machine is suitable for wet magnetic particle size below 3mm, pyrrhotite, roasted ore, ilmenite and other materials, but also for iron work coal, non-metallic minerals, building materials and other materials. Wet magnetic separator magnetic system, using high-quality ferrite material or rare earth magnets composite made of tube sheet average magnetic induction. Wet magnetic separator same time according to different specifications and performance can not be divided into wet permanent magnetic drum separator: Wet permanent magnet drum magnetic separator magnetic separator iron ore concentrator is a widely used, it applies in sorting the strong magnetic minerals. Wet permanent magnet drum magnetic separator in accordance with the tank body is divided into downstream, counter-style, semi-countercurrent three. Wet permanent magnet drum magnetic separator for ceramic industry magnetic separation plant outside except as sorting equipment, in recent years, also used as a filter in front of enrichment equipment to replace the magnetic dehydration trough. Strong magnetic roll separator for plastics: Strong magnetic separator many different types, according to the operating conditions into wet and dry; by the magnetic source is divided into electromagnetic and permanent magnet; press apparatus is structured into disc, roller, flat ring , vertical ring, induction roller and the like.

Wet magnetic separator maintenance inspection

1, wet magnetic separator newly installed tire prone to loosening, need to be checked regularly.
2, wet magnetic bearing the burden of the entire load, so good lubrication can greatly increase bearing life, it directly affects the rate of operation and service life of the machine, and thus need to inject lubricating oil of acceptable quality, the machine's main oiling Office: Roller bearings, rolling bearing, all of the gears, sliding plane, bearing activity.
3, regular inspection of various parts of a wet magnetic separator is working properly.
4, regular checks ceramic magnetic separator wear parts wear, the replacement of worn parts.
5, put the chassis plane of the active device, the timing cleaning dust and other things in order to avoid activities encountered when the machine is not broken material bearing on the chassis can not move, or even serious accidents.
6, slip separator bearing oil temperature is too high, it should immediately stop checking reasons, troubleshooting and then drive.
7, magnetic separator rotating gears operate if the impact of sound should be immediately stopped for inspection.

Separator steps:

1. Select the appropriate floor or ground. Installed on a flat, solid concrete or steel foundation, should remain stable and the retracting force uniform coolant magnetic separators feet, beware frame deformation caused due to uneven ground.
2. After the first bottom-fixed beam - magnetic head - vertical and dial - on the beam - excitation coil actuator installation pressure test, then use a crane to install the drive in turn means the end of the beam, the beam, magnetic heads, rotary, vertical magnetizing coils and other components.
3. After the installation is completed before commissioning respond tank leak test trial, with water to rinse all parts of the device, and then turn the power regulator slurry separators to the best.

Note separator installation:

1. Install a vertical gap of vertical focus is adjusted, the level of the turntable and turntable with two heads between the wheel and the two heads arc axis should coincide.
2. Install the precision requirements: the centerline deviation limit the device to ± 3mm, elevation limit deviation of ± 5mm; rows mounted recycling cross belt magnetic separator, centerline straightness tolerance of 3mm, relative elevation difference of no more than 3mm.
3. After installation ensure that machinery does not come loose, the line does not appear to detect leakage short circuit and so on.

Why must resolve magnetic separator magnetic field is not uniform

Magnetic product recovered to the trajectory of the magnetic mineral particles, by magnetic and mechanical forces acting on the magnetic mineral particles on the force to decide. The non-magnetic products into the mineral particles, due to the magnetic effect is very small, even without the magnetic force, Its trajectory is determined only by mechanical forces. When the magnetic field acting on the neodymium magnetic drum separators of mineral particles is greater than the mechanical force, magnetic mineral particles are attracted to the cylinder, and with the drum is rotated to remove mines as ore output, rather than the magnetic mineral particles with
As tailings slurry flow discharge.
Through magnetic separator for silica sand description of the process, we can know that it is because of the magnetic mineral particles in a magnetic field by the magnetic force of mechanical force to achieve magnetic separation work, then how can we make the magnetic field magnetic separator ore particles Magnetic greater than
Mechanical force, so that the mineral particles adsorbed onto rolls it? These and distribution and relationships with non-uniform magnetic field! Here, we will analyze why the magnetic separator is uneven.
According to the magnetic field intensity distribution, a uniform and non-uniform magnetic field points. Refers to the so-called uniform magnetic field magnitude and direction of the magnetic field strength of each point are the same. Instead of a uniform magnetic field is the magnetic field strength of the magnetic field points big and square
To not the same. As shown below, in a uniform magnetic field distribution of the magnetic field lines is uniform, but in an inhomogeneous magnetic field distribution of the magnetic field lines are uneven.
