water cooling electromagnetic separator for Quartz

PTMS MAGNETIC SEPARATOR

what is magnetic separation in chemistry？

Iron spots are caused by the presence of iron-containing contaminants in the body or glaze and can be very expensive for producers.
Contamination can occur naturally from iron-bearing minerals such as magnetite and hematite, or can be introduced by grinding, screening or deterioration of the plant.
Wanjiade's mission is to eliminate this pollution, regardless of its source, which means not only magnetic separation at a location within a plant.
The best way to solve the iron pollution problem is to remove the raw materials before they enter the factory.
Suppliers can be instructed to improve the quality of their products, but preliminary separation of impurity metals such as nuts, bolts, steel wire and smaller iron is still required.
Larger lines can use a suspended iron remover, while smaller irons can use a plate type iron remover.
The type of suspended iron remover that needs to be installed is stronger than the field strength of a standard suspended iron remover.
Wanjiade manufactures two types of suspended magnets, and CP magnets are the most commonly used units.
However, it is not suitable for this type of separation.
Wanjiade's 1000-type slurry separator is more powerful and can better separate metal impurities.
There is also a permanent magnet iron remover that will be mounted on a conveyor belt containing glaze or body to remove any large contaminants.
Once the material is mixed, ground and screened, it passes through the strongest magnetic separator.
The Wanjiade High Strength Filter is a high gradient magnetic separator capable of capturing fine ferrous and paramagnetic particles in liquids and slurries.
It produces a background magnetic field of about 5000 Gauss.
When strengthened in the matrix, this increases to 15-18,000 Gauss, which is sufficient to attract fine weak magnetic particles.
This has been proven to provide the best iron levels.
Not only is the separation performance excellent, but the equipment is fully automated.
Therefore, the maximum magnetic separation can always be guaranteed.
On manual cleaning devices such as pipes, the user has to rely on the operator to clean them.
Calculations show that the tube needs to be cleaned every 15 minutes to maintain separation performance.
This is physically impractical.
For HI filters, there is very little maintenance - the matrix may be checked once a month.
The next stage of the process is usually a spray dryer.
Spray dryers are notorious for introducing fine iron into materials, usually in combination with spray dried granules.
Therefore, the spray dried ceramic should pass through a high strength magnetic separator prior to storage.
Wanjiade recommends using a slurry remover.
When the material reaches the drum, the magnetic field attracts and holds the iron particles in the drum casing.
As the drum rotates, it transports the material through a fixed magnetic field.
The non-magnetic material falls freely from the housing while the ferrous particles remain firmly until they leave the magnetic field.
Many companies have promoted the use of rare earth rolls on spray dried materials, a high strength, high gradient, permanent magnet separator that optimally separates paramagnetic particles from dry products.
The advantage of using a drum is that the throughput on the drum is higher than the reel; the magnetic field on the drum is deeper than the drum; the maintenance on the drum is significantly lower; the RE roll requires regular belt changes, and the drum is not required.
The aim is to separate the free iron and iron associated with the spray dried particles.
For this reason, you do not need the additional strength of the RE roller, so the drum is the best solution.
As the final inspection before the press, Wan Jiade suggested installing a simple rare earth magnet.
Usually this is directly above the press.
These simple systems will remove any iron from the final storage silo and transport system and ensure that the product is clean before pressing.
An example of a magnetic system to be placed may be an elbow magnet above the press, a box magnet or a tubular magnet below the silo.
The preparation of the glaze is very similar to the magnetic treatment.
Many companies believe that glaze is more important than the body because it can be seen more easily.
Many companies first installed the HI filter on the glaze line and immediately saw the results.
Many times, HI filters can be supplied on a removable base for transport from one glaze tank to another.
Most HI filters used in glaze production have at least 5,000 Gaussian background fields.
Although it does not provide the same level of separation performance as ceramic traps, it is widely used in pipes in the ceramic industry.
Some companies even install these types of traps on water pipes because this is a source of large amounts of free iron.
In short, the magnetic separator is an important part of any ceramic industry production line.
Removal of iron-containing contaminants at multiple locations in the plant ensures that the final product is non-polluting, of the highest quality, while reducing the cost of the producer.
