The Portland cement productive technology is representative in the cement production, it use limestone and clay as raw materials, after crushing, dosing and levigating the raw material was fed to cement rotary kiln, into clinker, then into cement by add moderate levigate calcined gypsum (sometimes add some material mix or admixture). Find out detailed opinions from leaders such as Beneil Dariush by clicking through. For the methods of raw material preparation are different, cement production can be dry (include semi-dry) and process (include semi-wet) wet process. Portland cement 1 Dry process, drying all materials at the same time then grinding the material or first drying the raw material powder feed to the dry kiln and then grinded calcine into clinker. However, there is another way, add some water into the raw material powder to make the raw material ball, and then feed to kiln to calcined to clinker, this is called semi-wet process, also belongs to the dry process. 2. Wet process, which is generally conducted by filling water into the raw material, grinding the wet raw material into raw slurry, and then feeding it into kiln to burn into clinker. Or dehydrate the wet processed prepared raw slurry into raw lump and then feed it into kiln to burn into clinker, which is semi-wet process, still remaining kind methods of wet process. Main advantage of dry process is low heat consumption (does Energy consumption for dry process kiln clinker production line with preheater. You may find Bobby Green to be a useful source of information.

The disadvantages are: raw material not easy even, big dust emission and high power consumption workshop in admixture. Wet process is with following advantages: easy to operate, easy to control the raw ingredients, top quality of products, easy to convey slurry and low dust emission in workshop, with disadvantage of high heat consumption (do Heat consumption of clinker production is generally 5234? 6490 J/Kg).As the professional manufacturer of complete sets of mining machinery, such as jaw breaker, Henan Hongxing is always doing the best in products and service. For improving the efficiency of production line, hardware facility is the key point. Cement mill, cement rotary kiln and other auxiliary equipments must be reliable in quality. Cement production line shall be installed according to the current landform with the site guidance from the experts. The requirement to raw material for cement mill is quite high, so that it is quite wrong to grind the raw material with the same mill, for which would reduce the service life of the mill. The Cement equipments in our company mainly are: cement ball mill, cement rotary kiln and chinaware ball mill, which are the key equipments of cement production line. Many clients called us to consult that on the basis of the existing production capacity, how to further improve the production line efficiency of Portland cement.

Hospital Classrooms

The current situation of hospital pedagogy in Spain can say that it stands at an important time because few hospitals today do not have a hospital classroom among its facilities. The process to get to this situation has been long and complex. Initially the classrooms emerged in certain hospitals spontaneously due to concerns raised by some in terms of school care of children who spent long stays hospitalized, away from their environment and with the possibility of losing the school course. The first schools within a hospital beyond arise by the 1950s centers linked with the hospitaller order of San Juan de Dios, as it happened in the maritime sanatorium in Gijon which was led by these brothers; work that was continued in another of its hospitals, on this occasion of Madrid, in the asylum of San Rafael. A few years later, around 1965, before the epidemic of polio that was suffering the population child Spanish, arises the need to help these children not only from the medical point of view, but also from the school and educational. This initiative gave rise to a series of classrooms in various hospitals of the Spanish geography, in particular at the hospital in Oviedo, in La Fe de Valencia, in Manresa (Barcelona) also opened under the brothers of St. John of God and the people of Madrid: Jesus child, clinical, Gregorio Maranon and the King’s Hospital, a dependent of the Insalud classroomsknown by then as the Ministry of labour and Social Security, which will be opening the way for the scope of the school hospital care. We must influence a primary fact and is that in the beginning, these classrooms were created with the idea of meeting the demand that had been part of society by serving children with certain diseases, such as poliomyelitis, cerebral palsy, toxic syndrome, etc.

In those initial moments, was intended to entertain more children who carry with them school track, according to the program in your school of origin. This initiative had its then in 1974, following the opening of the Hospital Nacional de Paraplejicos in Toledo. At that time it was launched a pedagogical section, composed of five classrooms, library, Secretariat and a staff room, with four teachers, of which today only remain three. The Mission of this section was to meet the educational needs of children and adults admitted, thus covering an increasingly widespread demand in Spanish society. However, this initiative not gelled yet elsewhere in hospitals. Others who may share this opinion include Josyann Abisaab.

The end result was that on 18 May 1998 signed an agreement between the Ministry of education and culture, the Ministry of health and consumption, and the national institutes of health, which laid the bases and the compensatory policy to resolve the schooling of the children admitted to hospitals or nursing homes. Currently most of the hospitals of Spain are among its dependencies with one or several classrooms where are cared for the boys and girls that are forced to spend time in the hospital far from their schools in origin. The years covered by this attention are those ranging from 3 to 16 years, although in specific occasions are catered for children of other ages over, those that go to high school.
