1883 |
The Italian entrepreneur Giovanni Batista Pisetta founded a limestone quarry in the location of the current cement plant; he was supplying limestone blocks for the construction of railways from the quarry. |
1891 |
Tests confirmed the suitability of the raw material for the production of Roman cement. |
1895 až 1914 |
Pisetta had two brick kilns built for clinker burning with a capacity of 70q per kiln. Later on, three more lime burning kilns were added, each with a capacity of about 140q. |
1922 |
Tests performed at a research institute in Brno and Berlin confirmed the superior quality of limestones and marls, and exceptional chemical and physical properties for the production of Portland cements. |
1926 |
The Spišek family bought the local quarries from Pisetta, created the public limited company Moravsko-slovenské cementárne [Moravian – Slovak cement plants] and had a cement plant built by the firm Curt von Gruber from Berlin. |
1929 |
The first cement plant was built, with one kiln with a capacity of 100 tonnes of clinker per day. At that time, the cement plant had a hammer crusher, a tank dryer, a raw mill, a cement mill, two cement silos and a manual packing area. |
1943 |
Two shaft kilns, four cement silos, a clinker hall, a raw mill and a second cement mill were added. |
1945 |
After the end of WWII, the cement plant in Horné Srnie, as the first cement plant in Slovakia, started to produce cement. |
1947 |
The cement plant became part of Slovenské cementárne a vápenky [Slovak cement plants and lime plants] with corporate headquarters located in Trenčín. |
1948 |
The fourth shaft kiln was built, mining in the quarry was mechanized by the use of excavators. |
1950 |
A separate organizational unit, the Hornosrnianska cementáreň, štátny podnik [Horné Srnie cement plant, state-owned enterprise] was created; it had an associated lime plant in Nové Mesto nad Váhom. |
1959 |
Major modernization of the plant. Four shaft kilns, a crushing plant, six raw material containers, a raw mill, three reinforced-concrete homogenization silos, a second mill, two wind screens and a complete slag drying station were built. |
1968 |
The 5th shaft kiln was put into operation. |
1970 |
Construction of an electrofilter for dust elimination from kilns. |
1988 |
Two concrete clinker silos with a capacity of 15 000 tonnes of clinker were built. |
1994 |
An electrofilter was put into operation, thanks to which today the plant emits less carbon than Western European cement plants. |
1998 |
Start of the construction of a new rotary kiln line. The conversion included the construction of a rotary kiln with a LUCE five-stage cyclone heat exchanger and with a calcining channel, as well as a clinker cooler, a raw material crushing plant, a pre-blending store, a homogenization silo, and a coal mill. |
2000 |
Start of the feeding of raw material into the kiln line and launch of the construction of a slag drying plant. |
2001 |
Commissioning of the slag drying plant. |
2003 |
Anew cement mill was commissioned |
2004 |
Use of TAP in the clinker burning process, reduction of the quantity of Cr6+ in cement. |
2005 |
Exhaust of kiln gases, by-pass disposal of chlorine in the system |
2006 |
Modernization of the bulk cement dispatch to road tank cars |
2007 |
Transport and feeding of additives into cement mills. |
2008 |
Start of the construction of fly ash silos and an oil storage, preparation of the construction of a cement silo |
2009 |
New cement silo + dispatch, fly ash silos – commissioning |
2010 |
Addition of storage tanks and dispensing weights on the raw mills. |
2011 |
Feeding of a grinding intensifier into cement mills, start of a conversion of the clinker cooler. |
