In Finale Ligure, a small fishing village on the Ligurian coast, where the art of lime production was already practised by ancient tradition, Antonio Ghigliazza began producing lime in kilns fired by wood and exported it in wooden barrels.
Giacomo and Angelo Ghigliazza moved the lime production to the nearby limestone quarry and built two Mix Fire Kilns.
The quarry was to become the main production centre for the company for over a century and a half.
Giacomo and Angelo’s sons built the first and second continuous kilns with coal combustion, based on their first experiences in neighbouring France. The kilns are made of concrete, have a round cross-section and an output of 20 T/D.
Arturo Ghigliazza set up and directed the first research and development team for new technologies to be applied to lime production and quarrying.
Venturi pipe suction systems known as “Tyfoon” were applied for the first time to existing coal combustion kilns, enabling the output of the kilns to be increased to 30 T/D. The first hydrator with a body made entirely of concrete is also produced.
The success of the innovations is such that other lime manufacturers ask to apply these technologies in their factories.
Arturo Ghigliazza moved to Milan, a large industrial centre in northern Italy, to better follow the development of new technologies. In parallel with his work as a technical assistant for the family company, he started to design and build lime plants for other manufacturers.
The first two Italian kilns abroad are built in Ethiopia.
At the end of the Second World War, Arturo Ghigliazza was joined by his nephew, Franco Accinelli, in designing and building plants for the lime industry. The family business was transformed into an industrial enterprise.
The family company is transformed into a public limited company: Fratelli Ghigliazza S.p.A. is born, with three production units (Finale Ligure, Genoa, Lucca).
Italy’s first kiln with fuel oil combustion was built in Merano.
Natural gas arrived in Italy and the first conversions of coal-fired furnaces began. These were the first steps in an evolution that would lead to the birth of CBK kilns.
The first modern lime kiln in India was built by a European company in Bombay.
SIC builds first PCC plant in Mexico.
Once the study and testing phase has been completed, SIC begins industrial production of the “S” series micronising mills.
On behalf of the national petrochemical company ENI, one of the largest plants for the production of lime milk for chemical use is built with a slaking capacity of 30 Tonn CaO/H.
The development of the “S” series mill technology leads to the birth of the “HPS” air separators. This completes a revolution that leads to a new way of designing hydration systems.
For the first time in Europe, on behalf of Ciment France / Italcementi, a complete line is created for the production of hydraulic lime for green/bio-building using modern equipment.
SIC’s new operational headquarters in Milan are officially opened.
