When the vibrating screen is in the normal working status, if the rotation is slow and the bearing has a high temperature, which show that the work of usual maintenance needs improving and the lubricants are needed. Routine maintenance is also very important. If the lubricant on the bearing is newly added, the problem maybe lies in the poor quality of the lubricants or adding too much on the bearing lubricants. The lubricant with poor quality will block the bearing and labyrinth seal. Therefore, the quality of lubricants is critical. The reasons for the poor screening quality may be the improper use or the blocking of the mesh. The increase of the fine-coarse-grained materials and moisture will result in that the material layer is too thick and the feeding is uneven.
As for the vibrating screen itself, the both sides of the sieve is not tight. If there is much noise in the screening process, the reasons maybe include that the bearing is damaged, the bolts loose, the breaks and the spring is damaged crossbeam. In addition to the bolt that can be tightened, the parts should be replaced in other three conditions. In view of the above failures, we can reduce the failure rate through routine maintenance. Before the starting up of the machine, checking the oil level of both sides. If the oil level is too high, which will lead to problems or the temperature of exciter rise operation; If the oil level is too low, which will cause the bearings to be prematurely damaged. Checking all bolts to ensure that all of them are tightened and after working for eight hours, re-tighten them.
Checking the tension of the V-belt to prevent slip at the start or work. Making sure the minimum clearance between all moving parts and fixtures. The feeding can not be conducted until the sieve is running smoothly to make sure the sieve works without load and before stopping the machine, it is necessary to clean the materials on the sieve surface. In short, summarizing the failures of mine vibrating screen is to prevent and reduce the occurrence of the failure. If the failure emerged, we can timely settle them to minimize the impact on production. Rock crusher cone: ball mill:
A slope is a portion of land that presents an inclination that can assume a situation of instability after an original profile has been modified with artificial relevant interventions that have been able to modify the initial equilibrium conditions. The equilibrium equations and the constitutive equations that describe the ideal behavior of the land are used for the study of the stability of slopes. The grounds are multiphase systems which makes the equations of equilibrium of great complexity, so we must introduce simplified assumptions. The constitutive laws of soil implificadas are applied to a perfectly plastic rigid model. We accept the hypothesis that soil resistance is function of cohesion and the angle of internal friction, characteristic of the plastic State, to give validity to the criterion of Mohr-Coulomb break. The method of balance limit (LEM) studied the equilibrium of a rigid body (talus) on a sliding surface. Assuming that the balance was met compares the tensions of cutting with the maximum allowable voltage, valued by the breakage of Coulomb criterion. Some of the final balance, as the major methods, consider the overall balance of rigid body. Others, when there is a lack of homogeneity, divide the body into slices whereas the balance of each, as Bishop, Janbu or Fellenius methods. The method of slices for the study of the stability of a slope is a method of last balance that divides the mass of land susceptible to slipping into slices. Original author and source of the article
The substance is a question related with the being, that can par excellence be considered the Metaphysical question. For the philosophy of Aristotle to ask on what it is the Being is the same that to ask what it is the substance; the substance for the master of the 2 secondary school, is everything what it exists, therefore everything what it exists is substance or the sensation of the substance. According to old conception of metaphysics had a multiplicity substances, which were commanded hierarchically. Spinoza going as that in the one against hand of the multiple substance conception assevera that a substance only exists, namely, God. God, who is the substance, the first bedding of all the things, not needing to send exactly to no being beyond itself, therefore is cause of itself exactly, therefore, such reality cannot be conceived as not existing. It writes Spinoza in the third definition: ‘ ‘ For substance I understand what it exists exactly in itself and by itself it is conceived, that is, that whose concept does not demand the concept of another thing of which it must be formado.’ ‘ The clear substance idea is of a being that does not lack of nobody to subsistir, it is the perfect being that subsiste for itself. Of this substance definition, she is necessary to affirm its real existence, because if we denied the existence to it, in a similar way we would destroy the definition, therefore, for its definition it is for its existence as real. for if having this intuition of the clear and distinct definition for idea, that can be considered infallible, we know that the substance exists necessarily in the reality.
We recommend to start the second day of his visit to Petersburgo with an excursion to Zaiachiy (Hare) island of Gorkovskaya metro station.There is where the city was founded.One of the attractions to visit here is the fortress of Peter and Paul, with several buildings located within its walls.At noon the air is filled with the bellow of a barrel this is one of the oldest traditions of the city.Thanks to her during the times of the Russian tsars people can learn that it was noon.If you are interested in the history of Russia, who are also encouraged to visit the Cathedral of Peter and Paul in which all the Russian emperors Pedro I Nicolas II are buried.Also the monument to Pedro I and enjoy the view of the Nevsky Avenue scene. Then you can go by Kronverkskaya fill to reach the Museum of the Marina.De somehow more a stella there is granite that indicates the place where the participants of the rebellion of the Decembrists were executed (1826). Fill takes back to the Alexandrovsky Park, with plenty of restaurants and cafes located in the same, which is very convenient when you are tired and want to take an aperitif. The next step would be to go in the direction of the Troitsky bridge (you will see a mosque in the distance).Turn to Embankment Petrovskaya and arrives at another attraction a modest house built especially to Peter the great (the cabin of Peter the great), the first House in Petersburgo.The famous Cruiser Aurora, symbol of the October revolution, is a little further away.The Aurora Cruiser Museum operates from 10.30 to 16.00 (closed Mondays and Fridays). The cabin of Peter the great works: Sunday Wednesday: 10.00 18.00 Monday: 10.00 to 17.00 Tuesday: closed the day 3 visit the central city of Nevsky Prospect Street, and the Ruso.Un Museum stroll through the perspective of the Navy of Fontanka River you will not more than half an hour.However, If on its way to the river you can visit all the area attractions, full day will be devoted to this.We will not describe these cue points: each of them deserves an article separate.List of places of interest include: the Church of el Salvador on the blood, the Kazan Cathedral, the casa del libro (excellent for tour guides and maps), Gostiny Dvor shopping mall, the Anichkov bridge and many others.
Those who need a guided tour can join one of those who are in the cabin next to Gostiny Dvor. When you get tired, you can sit at one of the banks in the small square of Ostrovsky, observe the monument to Catherine the great, and feed the pigeons.The dominant architectural square is Alexandrinsky theatre. Nevsky Avenue is also the place where one can easily find a place to dine in there are a lot of cafes and restaurants here. The Russian State Museum is another educational point not to be missed.Is located not far from the Church of the Savior on the blood and there is a monument to the famous Russian poet Pushkin, standing in front of him.To be continued Welcome to Travelling2peru.com (Leaders in Peruvian tourism, Machu Picchu and Cusco Tours) International posts, dedicated to all travelers who wish to travel around the world.

The pupils were guided to describe, to relate the natural and social facts, to make analogies between them and to elaborate its generalizations or syntheses. To explain them yes, however preventing any form of understanding or subjectivity that confused the observer with the analysis object. He intended himself to teach a neutral Geography. This perspective also marked the production of didactic books until middle of the decade of 70 and many still present in its body ideas, interpretations or even though expectations of learning defended by traditional geography. (BRAZIL, 1998, P. 21) With this it is observed as the education of Geography in Brazil, marked for the memorarizao of the facts and not for the interpretations of the events was introduced. Thus being Geography was fardado simply to decorate name of climate vegetation population agriculture cities geographic basic, Reduction of the knowledge for not the contextualizao of the pupil, Reduction to the time of consideration of the knowledge, in special in the initial series of basic education. From the decade of 1950 they had appeared you vary you criticize to such model of education (ALTO, 2005), these methods and theories of traditional Geography had become insufficient to learn the complexity that happens in ' ' space geogrfico' '.
The country passed for great development and that this would be directly on the formation of professionals technician, for the manuscript of the news you scheme of the development. In this context it appeared new a proposal educational that passed to be called tecnicista process or pedagogia tecnicista. According to Libneo (2001), it was seen necessity to prepare hand of qualified workmanship for atenderessa increasing industrialization, with this the school passes to be seen as this place for such preparation. PEDAGOGIA TECNICISTA According to Spider (1996) the tecnicista education, whose philosophical base of this pedagogia is inspired especially in the behaviorista theory, was a comportamentalista chain organized by Skinner (1904-1990).
It is not uncommon to appear somebody saying that a research such or which arrived the conclusion that psychoanalysis valley in such a way how much placebo. Whenever I hear this I am of certain curious form. I do not know if these cited research exists, but this article to be able to continue, we go to assume that yes. First so that exactly if this using placebo? It will be for some pain of the soul? It will be for some suffering of the citizen? It will be for some badly to be of after-modernity? It will be for belly ache? At last, always it is of it are that therapeutical action if this speaking. These same questions send to one another one? so that it serves psychoanalysis? Now it follows a personal reflection very? for nothing! Or better, psychoanalysis simply does not serve. If to serve for something, is not psychoanalysis. If to bring some profit, is not psychoanalysis. If it cured, then decidedly it is not psychoanalysis.
If it informed some newness to the patient, then it is not psychoanalysis. The psychoanalysis not cure, does not add, does not inform new features, it does not decide, it does not remove, not of. Psychoanalysis is an experience that when it finishes, nothing surplus. Track does not leave. If to be track was not psychoanalysis. Psychoanalysis does not decide suffering? if it decided, was not psychoanalysis. This is the great mystery of the psychoanalysis? it can be transmitted, but she cannot be insured, possessed.
It possesss nobody it. Each one speaks from its clinic, but not OF the psychoanalysis. The psychoanalysis simply Is psychoanalysis. Therefore, it cannot be compared with psychology, psychiatry or placebos, for this its only character? it cannot be apprehended? but lived deeply.
