proizvodnja cementa se začne s pridobivanjem surovine v kamnolomu plesko nad trbovljami. najpomembnejši osnovni surovini sta apnenec in lapor. Surovino pridobivamo z miniranjem, nato jo drobimo, sušimo ter v pravilnem razmerju zmešamo. na koncu jo fino zmeljemo, tako da nastane surovinska mešanica.

kamnolom je od tovarne oddaljen 3 kilometre, transport zdrobljenega materiala do tovarne pa poteka po rovu.

Cement production begins with the extraction of raw material in Plesko quarry above Trbovlje. The most important basic raw materials are limestone and marl. The raw material is obtained by mining, it is then crushed, dried and mixed in the correct ratio. At the end it is ground to a fine powder to get a raw mix material.

The quarry is 3 kilometers away from the factory; transport of the crushed material to the factory is by the tunnel.

material iz kamnoloma transportiramo do mlina surovine in shranjujemo v silos. za ustrezno kemijsko sestavo, ki omogoča dobro žganje in oblikovanje mineralov klinkerja v peči, je potrebno surovinski mešanici dodati različne materiale, kot so pepelnata žlindra, boksit, piritni ogorki ali železova ruda. Ustrezno pripravljena mešanica gre nato v mlin, ki jo zmelje v fino surovinsko moko. Surovinsko moko transportiramo v enega od dveh silosov homogenizacije, kjer je pripravljena za žganje. proces žganja oz. proizvodnje klinkerja poteka v treh delih: v izmenjevalcu toplote, rotacijski peči ter v hladilcu klinkerja.

v izmenjevalcu toplote se surovinska moka, preden vstopi v peč, segreje. peč ima obliko cevi, njena nagnjenost in vrtenje pa omogočata potovanje materiala po peči proti vse večjim temperaturam na primarni strani, kjer je nameščen gorilec. najvišja temperatura materiala v peči - 1450°C – je dosežena v coni sintranja, kjer potekajo najpomembnejše kemijske in fizikalne reakcije. na tej stopnji znaša temperature plamena približno 2200°C. na izstopni strani peči pada klinker v hladilec, kjer ga hitro ohladimo. končni produkt žganja je cementni klinker v obliki temno sivih granul premera približno 3 cm.

Material from the quarry is transported to the raw mill and stored in silos. For the appropriate chemical composition that allows good burning and the creation of clinker minerals in the kiln, the raw materials require additional materials such as ash, slag, bauxite, pirite and/ or iron ore. A properly prepared mixture then goes into the mill, which grinds it to a fine raw material (flour).Flour raw material is transported to one of two homogenization silos where it is ready for burning. The burning process (clinker production) consists of three parts: the heat exchanger (pre-heater tower), rotary kiln and clinker cooler.

In the pre-heater tower, the raw material heats up before it enters the kiln. The kiln is in the form of a tube, its gradient and its rotation allow material in the kiln to travel to the increasing temperatures at the primary side where the burner is installed. The highest material temperature in the kiln - 1450°C - is achieved in the sintering zone where the most important chemical and physical reactions take place. At this point the flame temperature is approximately 2200°C. On the outlet side of the kiln, clinker falls into the clinker cooler, where it is cooled quickly. The end product of burning is a cement clinker in shape of dark gray granulates of approximately 3 cm diameter.

kontrolna soba je postavljena v središče cementarne in predstavlja njeno srce, od koder operaterji nadzorujejo in vodijo celoten proces proizvodnje od transporta surovine iz kamnoloma do tovarne, pripravo surovine, žganje klinkerja in mletje cementa, vse do skladiščenja proizvedenega cementa v silose. Delo v kontrolni sobi poteka s pomočjo ekspertnega kontrolnega sistema, kar zahteva obilo računalniške opreme. kontrolna soba je tudi nadzorni center za monitoring emisij cementarne in center za kontrolo varnostnih procedur za vso tovarno.

The control room is located in the center of the cement plant and represents its heart, from where operators monitor and manage the entire production process from raw material transport from the quarry to the factory, raw material preparation, clinker burning and cement grinding, all the way to storage of cement in silos. Work in the control room is done with the aid of an expert control system, which requires lots of computer equipment. The control room is the control center for monitoring emissions of the cement plant and control center for safety procedures for the whole factory.

informacijska točka je postavljena v parku v južnem delu cementarne. iz tega dela je možen pogled na večji del cementarniških objektov. na tem mestu predstavljamo zgodovino trboveljske cementarne, ustanovljene s strani trboveljske premogokopne družbe davnega leta 1876. predstavljamo tudi skupino lafarge, največjega proizvajalca gradbenih materialov na svetu, čigar del je trboveljska cementarna od leta 2002. na mestu, ki služi tudi počitku po industrijski poti, boste izvedeli tudi več o investicijah v cementarno v zadnjih desetih letih.

The Information point is set in a park in the southern part of the cement plant. From this area it is possible to see most of the cement plant structures. At this point, we present the history of Trbovlje cement plant, which was set up by the Trbovlje Mining Company back in 1876. We are also introducing the Lafarge Group, the largest manufacturer of construction materials in the world, whose Trbovlje plant has been a part of since 2002. On the site, which also serves as a rest place on the industrial way, you will also learn more about investments done in the cement plant in the last ten years.

proizvedene cemente skladiščimo v osmih silosih s skupno zmogljivostjo okrog 33.000 ton. S pomočjo transportnih polžev, elevatorjev in transportnih drč skladiščeni cement iz silosov odpremimo do posameznih odpremnih mest na nakladalni postaji, od tod pa ga z različnimi prometnimi sredstvi dostavljamo do kupcev. odprema cementa poteka po železnici in cesti, v vrečah ali v cisternah.

Produced cement is stored in eight silos with a total capacity of around 33,000 tones. With the help of transport airslides, elevators and conveyors the stored cement is dispatched from silos to dispatch locations at the loading station, and is from there delivered to customers by different means of transport. Delivery of cement can by rail or by road, in bags or in bulk.

lafarge se je v vseh državah, v katerih je prisoten, zavezal k odgovornemu ravnanju. lafargeovi izdelki so visoko kakovostni in zadovoljujejo potrebe kupcev ter okolja. odgovorno ravnanje pomeni zmanjševanje okoljskega odtisa, večjo skrb za zdravje in za varnost zaposlenih, pa tudi spoštovanje ter podporo razvoju skupnosti.

Cementarna predstavlja t.i. Bat tovarno, opremljeno z najboljšimi razpoložljivimi tehnologijami. v njej je možno nadomeščati fosilna goriva, s čimer prispevamo k ohranjevanju naravnih virov, omejujemo izpuste toplogrednih plinov v ozračje ter znižujemo količino še uporabnih odpadkov, ki bi sicer končali v okolju. z alternativnimi materiali v proizvodnji recikliramo odpadke drugih industrij, zmanjšujemo količine odpadkov v okolju in omejujejo izpuste toplogrednih plinov v ozračje.

okoljski vidik je pomemben tudi pri razvoju novih izdelkov, pri katerem upoštevamo celoten življenjski cikel izdelkov, torej tudi po vgradnji. takšen pristop zagotavljajo novi izdelki, ki bolje zadovoljujejo potrebe kupcev, obenem pa manj obremenjujejo okolje.

Lafarge is committed to act as a responsible industrial player in each country in which we operate. Lafarge produces high quality materials to meet customers and communities needs. Being responsible includes reducing our environmental footprint, taking care of our employees' health and safety, respecting and contributing to wider initiatives in the society.

The Trbovlje cement plant represents the so-called BAT factory, equipped with the best available technologies. There is the possibility to replace fossil fuels, thus contributing to the conservation of natural resources, limiting emissions of greenhouse gases in the atmosphere and decreasing the amount of still useful waste that would otherwise end up in landfills. With alternative materials in our process we recycle waste from other industries, reducing the quantity of waste in the environment and limiting the emissions of greenhouse gases in the atmosphere.

The environmental aspect is also important in developing new products, which take into account the entire life cycle of products, also after installation. Such approaches provide new products that better meet customer needs, while being more sustainable for the environment.

zaključna faza proizvodnje cementa je mletje klinkerja, gipsa in dodatkov v mlinu cementa. Dodatki pri mletju so lahko tuf (oz. pucolan), žlindra, elektrofiltrski pepel in apnenec. Gips dodajamo za regulacijo vezanja, saj bi se cement brez dodanega gipsa v prisotnosti vode takoj strdil in ne bi bil primeren za vgrajevanje. trboveljska cementarna proizvaja več vrst cementov, ki zadovoljujejo različne potrebe uporabnikov cementa, in se med seboj razlikujejo po vrsti in količini dodatkov, zato imajo različno trdnost, obdelavnost in čas vezanja.

klinker in dodatke meljemo v cevnem mlinu. za mletje uporabljamo kinetično energijo krogel, ki se sprošča v mlinu zaradi njegove rotacije. Cement, ki ustreza zahtevam finosti, transportiramo in shranjujemo v silosih cementa.

The final stage of cement production is grinding of clinker, gypsum and additives in the cement mill. Additives at grinding can be tuff (or pozzelan), slag, fly ash and limestone. Gypsum is added to control setting time, because without it the cement would immediately harden in the presence of water and would not be suitable for forming and mounting.

Trbovlje cement plant produces several types of cements, which satisfy different needs of our customers. They vary in type and quantity of additives to have different strength, workability and setting time.

Clinker and additives are milled in the tubular mill. For milling the kinetic energy of grinding balls is used, which is released in the mill due to its rotation. Cement, which meets the requirements of fineness, is transported and stored in cement silos.
