PTMS MAGNETIC SEPARATOR

what is magnetic separation process？

Building sanitary ceramics manufacturers pay more and more attention to the problem of iron removal. Many enterprises have listed it on the agenda. The use of iron removers has been expanding, and the original glaze has been developed to remove iron and to remove iron.

1. Building sanitary ceramics manufacturers pay more and more attention to the problem of iron removal. Many enterprises have listed it on the agenda. The main leaders personally questioned or took over the leadership directly. The use of iron removers continues to expand, from the original glaze removal of iron to the billet and iron removal. More and more products are needed to remove iron, including daily-use ceramics, sanitary ware and all kinds of light-white glazed wall tiles and polished tiles. In addition to the iron requirements are also getting higher and higher, a production line from the original without the use of iron remover to the installation of a separator, the development of the installation of 3 to 4 multi-stage tandem separator, a ferromagnetic bar of the iron removal tank is also the original one or two Ten branches have grown to two or three hundred, and investment has grown.

2. Due to the excessive consumption of mine resources, many enterprises have been unable to find nearby and cannot afford to buy low-iron standard raw materials. They have to use downstream processing methods and use iron removers in large quantities. The maximum number of iron removal processes on one line has reached more than ten. As a worker, the cost of iron removal is getting higher and higher.

3, the cleaning method is all based on manual selection, the quality is difficult to guarantee. Usually a group of magnetic rods 100 ~ 300, each class 1 ~ 3 workers, one after another in turn to wash in turn, about 1 ~ 2h wash once, when the raw material contains high iron, often appear around the magnetic bar The iron mud impurity is thicker and the iron removal effect is significantly reduced. Coupled with a lot of people's emotional changes, quality management is difficult to control.

4, the permanent magnets sold in the market, the quality is unstable, too many manufacturers, the brand is too mixed, there are many for the shoddy products, using inferior materials, the ends of the rods are not tightly sealed. After these products are flooding the market, the average life of the magnetic rods used by enterprises is declining. Secondly, the “nominal” of the magnetic bar B value in the market is generally high, mostly higher than the measured value (50-100)%.

5, dry powder iron removal using the pump vibration cabinet (frame) type permanent magnet iron remover and belt drive iron remover, mainly used to remove the rust particles of the powder in the long-distance transport process, the effect is good, the use of units Constantly increase and expand.

6, the electromagnetic iron remover development trial time is earlier, the reaction can be, especially the high-power strong magnetic field on the separation of the weak magnetic material in the ore, but the investment is too large, the power consumption is more, the service life is not long, thus affecting Its promotion and application.

7. The ceramic raw materials of the developed countries in the world are all produced by centralized processing. Their iron-removing equipments are mostly large-sized, large-flow, high-power, fully automatic electromagnetic iron removers, which are bulky and expensive, and hundreds of thousands. More than a few million yuan.

8. At present, China's ceramics manufacturing enterprises also very much hope that the manufacturers of iron removal equipment will produce new iron-removing products with strong magnetic separation ability, long service life, high degree of automation and relatively economical application. Specific requirements:

(1) The value of the permanent magnet ferromagnetic bar should be above 6000 GS, and the use temperature should be above 70-80 °C, because some raw materials can reach 70 °C above the temperature of the ball mill. The service life should be guaranteed for more than two years, and the B value should not be reduced by 50%.

(2) The magnetic induction intensity of the electromagnetic iron remover is high, which is the requirement of high whiteness products, but the manufacturing and purchasing costs are reduced, the electromagnetic energy is higher than the replacement efficiency, and the second is to make the sealing technology of the magnetic conductive material to avoid oxidation. Shorten the service life. Third, a variety of iron separators with the same flow rate and different power should be produced to meet the needs of economical use in multi-stage series.

(3) The degree of automation of iron removal is high. First, no manual intervention is required. Second, the cleaning cycle is adjustable. Third, waste slurry (powder) and water are the least, especially for glaze removal. Fourth, sewage treatment and recycling. At the time, the waste water of the iron separator should be specially treated.

(4) The use of the spray drying tower requires a large effective flow rate, continuous uninterrupted, and the iron removal effect is better.

(5) The structure should be simple, the assembly and disassembly and docking, the operation control and maintenance are easy, the volume is as small as possible, the use is safe and reliable, and it can adapt to the old production and transformation installation.

(6) In the pulp (powder) transmission route, high-quality stainless steel materials should be used to prevent secondary rust and other impurities from being contaminated.
