The design of the sand making machine technological process should use the dry production process which relatively have little influence on the environment at the premise of meeting the concrete aggregate technical requirements. Using wet production process must take reasonable wastewater treatment process for the comprehensive utilization of waste water, waste residue, waste to treasure, and minimize the waste disposal to meet demands of environmental protection. In the process of mining, processing, it is easy to bring damage and harm to the environment and human life environmental, which include the damage on vegetation and slope stability caused by material mining body, the dust and noise generating in the process of crushing and screening, which have very seriously impact on the air quality and human survival environment. What s more, the waste water and waste residue generating in washing the screening machine enter the river valley, land, which will impact the environment a lot. Mall of the air volume, which will also cause the partial burn. the water leakage of the water jacket caused the partial operation. Coal for gasification must be in good quality, which is with small stickiness, small volatile, to block diameter less than 40 mm, moderate lump. Educate yourself with thoughts from ConocoPhillips.
If using coal with large stickiness, which can cause the furnace carbonization layer into a paste best gas furnace slag and serious impact on gas production, it is also possible damage the equipment. It also can cause partial or partial burn explosion. So the quality of the coal is very important. Before natural gas became widely available in the 1940s, many North American and European cities used coal gas as a heating and lighting fuel. It was referred to variously as blue gas, producer gas, water gas, town gas or fuel gas. Often using the same low-pressure mains for distribution, natural gas replaced fuel gas in most uses by the 1950s because of its greater heating value and lack of contaminants. The ball mill is a grid type.The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by material input device.
Through simplified umdiagrama the visualization is possible> of the principaisestgios of the cycle of life of a product. The first period of training, extration of natural resources, realizado for suppliers, that take care of of the extration and the production dasmatrias-cousins and/or components. As the deprodutos period of training is the transformation under the control of the industries. The third period of training, preservation eexpedio, are generally under the control of the manufacturer, even so maissofisticados products can need a mesh of suppliers and contractors. The room period of training, of the use for the consumer, is influenciadopelo project of the product and for the degree of continuous interaction of the manufacturer.In the fifth period of training, an obsolete or defective product already discarded is ourevisado.
As and the third periods of training are seen as those where it has amaior ambient responsibility of the industry, but inside efora the increasing vision of the corporations is of that an ambiently responsible product minimizaseus ambient impacts in all its five periods of training. A dedados inventory is also elaborated that consists of the collection and procedures of calculations (ISO 14041:1998). Demassa consists in a rocking and energy, where the total that enters in the system in study must be equal aoque leaves. Through the application of the ACV in the manufacture of its products, the company will be able to conclude which the products contributes of negative form, paraa rise of standards of emissions of pollutants in half the liquid, gaseous eslido. She will be able to also verify, for example, which or which the products, contribuemde significant form for not the attendance the standards of poluentesestabelecidos by the legislation, as well as those demanded standards pelosclientes. So that the Evaluation of the Cycle of Life produces resultadosconfiveis, you talked back e, above all, comparable, is necessary that osimpactos ambient associates to the mentioned interactions are avaliadosatravs of methodologies and systematic and standardized procedures. .
In this direction, we will search to establish with the pupils and the pertaining to school community a more including reflection on the existing ambient degradation in the Land division Green Dream, pertaining locality to the quarter, where many pupils inhabit, specifically in relation to the forest fires practised in the band of Atlantic bush that if extends for the land division, to the accumulation of garbage deposited in the bush and strips of land, the burning of the domiciliary garbage (since the garbage collection is assistemtica and irregular in that one locality) and the irregular creation of the cattle (extensive pasture). As metodolgicos procedures, they will be carried through: wheels of colloquy for survey of previous knowledge, lesson of field for the quarter, questionnaires answered for the parents on positive and negative aspects of the quarter, drawings produced for the pupils, ecological walk for the school, collective confection of posters and mural with the photos of the carried through activities, exposition in the patio of the school. As end item, it will have the confection of a Cartilha de Ambient Educao to be delivers to the families of the pupils and the local community, with sights to the acquisition of positive attitudes ahead of the local environment, the change of attitudes and the formation of the ecological citizen..
The author seems critical very to the proliferation of the industries in the great centers, that for consequence, provoke the pollution of waters and air (and those described problems aggravate all previously). In view of these problems, the author presents as solution, or as goal to brighten up these problems the urban planning, and the fiscalization in the emission of pollutants. The fiscalization of emission of pollutants in Brazil revealed a sufficiently arduous task, for basically two reasons: the first one, is the fact of that the proper recklessness of the government in fiscalizing if showed incapable to regulate the emissions; as the reason is explained by the concern at this moment (relembrando) to be of attraction of companies, that is, to attract the dirty technologies, for ‘ ‘ desenvolver’ ‘ the Brazilian industrial park. Then if it could not propagate the idea of control of pollutants, and yes to propagate the idea of that if polua in Brazil (as it was the slogan at the time). To another idea displayed for the author, he is of the urban planning, what she is basically one of the ideas central offices of the Brazilian government of this moment, ‘ ‘ to plan the development of pas’ ‘. Thus, Moreira, incorporates this idea produced in the ditatorial government, it reproduces and it for some moments in the didactic book, as for example: ‘ ‘ Now that Brazil initiates pulled out its for the development, is necessary planejar’ ‘ (MOREIRA 1976 p.242), or through the enumeration and of the explanation of the agencies of regional planning of Brazil, as the SUDENE (Supervision of the northeast Development), the SUFRAMA (Supervision of Development of the Zona Franca of Manaus), that they would make possible, in the vision of the author, the development of these regions, consequently, the development of Brazil. Discoursing on ‘ ‘ desenvolvimento’ ‘ of the Amaznia, with the construction of great highways (as the Transamaznica), with the setting of great establishments, the author continues in the reproduction of speeches of the government, affirming that the current process caused impact in the environment, as the deforestation, and in the proper ambient balance, however, these they were consequences of the development process, that would have to be understood as main goal, and justification of any impact (MOREIRA, 1976).
