Screw conveyors analysis

Pužni transporteri su transportna sredstva neprekidnog toka koji služe za prijenos većih količina materijala u industrijskoj grani. To su transporteri koji ne podnose preopterećenje jer nastaje zagušivanje na pojedinim mjestima unutar transportne cijevi, a posebice na mjestima gdje se nalaze srednji ležajevi. To su strojevi s velikim mogućnostima primjene, a sve u zavisnosti o vrsti materijala koji se transportira. Domena primjene tih transportera, s obzirom na svojstva tereta dosta je ograničena. Nisu pogodni za grube materijale krupnih komada, kao ni za one koji se lako drobe, niti za ljepljive ili za materijale koji se gruda. Najpogodniji su za transport sitno zrnastih i brašnastih materijala. Transport pomoću pužnih transportera predstavlja ravnomjeran priljev materijala, a što znači ravnomjeran tok transporta uzduž cijele transportne linije. U ovome završnom radu pod naslovom Analiza pužnih transportera istražen je i proučen povijesni razvoj i tehničko-tehnološke značajke pužnih transportera, tih suvremenih i prekrcajnih sredstava bez kojih je postao nezamisliv život, poglavito za velike količine materijala u kojima uveliko nadmašuju ljudski rad. Analizirani su s njihovim tehničkim, tehnološkim i eksploatacijskim obilježjima i parametri, kao i stupnju iskoristivosti prilikom prekrcaja materijala. Rad je obrađen u šest cjelina s uvodnim i zaključnim razmatranjima zajedno s odgovarajućom literaturom.Screw conveyors are continuous flow conveying means which are used to transport large quantities of materials in industry. These are conveyors that do not tolerate overload because of the congestion at certain locations within the conveying pipe, especially in the places where the middle bearings are. These machines have wide range of usage which depends on the type of the material that is being transported. Considering the cargo characteristics, the range of their usage is quite limited. They are not suitable for rough and bulk materials, as well as for those that crumble, are sticky or can crumple. They are most suitable for the transport of fine grain and floury materials. Transport via screw conveyors represents an equal flow of the material, which means a smooth flow of transport along the entire transport line. In this final thesis titled Screw conveyors analysis, I did a research and a study of the historical development and the technical-technological features of screw conveyors, these modern transship means without which the life became unimaginable, especially for large quantities of materials in which they greatly surpass human work. I analyzed their technical, technological and exploitation features, as well as the degree of usage during transshipping. This thesis is divided into six units with introduction and conclusion with the corresponding literature
