Advantages of ore dressing plant used in Barite Barite powder is white or gray crystalline powder, is an important mineral containing barium, chemically inert, good stability, acid, density, hardness, high specific gravity, high whiteness, can absorb the harmful rays (x-ray and?-rays), etc., to glass gloss, non-magnetic and non-toxic. Thus, widely used in chemical, paint, rubber, glass, paper, medicine and other fields, according to the latest statistics, the size of the use of more than 2000 items. high specific gravity, high whiteness, can absorb the harmful rays (x-ray and?-rays), etc., to glass gloss, non-magnetic and non-toxic. Thus, widely used in chemical, paint, rubber, glass, paper, medicine and other fields, according to the latest statistics, the size of the use of more than 2000 items. The most commonly used crushers and grinding mills in iron ore crushing and grinding process for iron ore mining are mill, ultrafine grinding ball mill, etc.

In iron ore mining, miner usually choose to complete iron ore crushing plant for metallurgy. At present, the most popular iron ore production line consists of two jaw crushers. After beening crushed, the material will be transported for the magnetic separation, and then into the ball mill for grinding. The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of rings and rolls which are rolling in the ring channels are driven by dial through plunger. After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the middle of first dial evenly; the materials will be driven to the edge of dial by centrifugal force, and fall into the channels and ring are pressed, crushed and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground. The high pressure centrifugal blower inhale air from the outside and blow the materials which are ground in the third ring to powder Separator.

The rotating turbo in the powder Separator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air mixed with very little fineness which are purified by impulse dust catcher and discharged by blower and muffler. 1 High-efficiency and low consumption With the same end-products fineness and motor power, its output is over 1 time of that of Jet Mill, Mix Mill and Ball Mill. 2 Easy-damaged parts with longer working life The grinding roll and ring are made of special materials. Generally, their work life is more than one year, but, which could eat up to over 3 years, when it processes calcium carbonate and Calcite. 3 Security and Reliablity Because there are no rolling bearing and bolts in the grinding chamber, we can not see the problems of easily damaged and sealings and bearings machine destroyed due to the looseness bolts. 4. Cleansing and Environment Protection Adoption of press dust collector and muffler reduces the industrial dust pollution and noise, which reaches the National Standard.

As you can see, live in the language, besides giving us the possibility of autoobservarnos and reach the reflex knowledge, generates an increase in the sense of differentiation of each other and the world that we experience as an objective and produces an extension and complexity of subjectivity. Therefore, just as we ordered the external world, we must also sort that subjective inner world in such a way that us a sense of stability and continuity and make us viable experience of being one differentiated among each other. As Maturana indicated: the distinction of the self is an overwhelming experience () once it occurs, that distinction becomes the point of reference for all subsequent distinctions. An ontological approach to the explanation of the human person. If we want to develop descriptions and appropriate explanations of the personal human system we are forced, given their specific characteristics, conscience and subjectivity, to always adopt an ontological point of view (Guidano, 1987, 1990, 1991).

Peculiar and unique from the observation of a personal phenomenon is that while we see it happen always, and at the same time, two experiences: 1) our observers that we are of the phenomenon, and 2) experience that happens the person observed. In other words, a person is not just something that happens before us as observers to try to give an explanation of something, that a person is, first, an experience for someone. The narrative organization of personal experience. Examine the notion of person from an ontological perspective implies observing the experience itself personhood as the case that has that experience, as w. James (1890), I would say to the I and you concrete and particular. This perspective understand with Guidano (1991, 1993) that in every moment of your life each person has immediate experience of being herself (a self that experiences) and, simultaneously, an explanation of that experience (a my which orders and explains the experience), which gives you a sense of herself in Biographical terms processed at the level of narrative thinking.
