WE ARE PROUD TO REPRESENT THE FUTURE OF A TRADITION THAT HAS GONE THROUGH THREE CENTURIES OF THE LIME HISTORY 1840-1880
1936
In Finale Ligure, a small village on italian coast, Angelo Ghigliazza, using kilns manually fed with wood, started the lime production that was exported in wooden barrels loaded on boats.
Two kilns were supplied and installed in Ethiopia. This was the first foreign project carried out by the company.
1880-1900 Giacomo and Angelo Ghigliazza transfer the lime production in the nearby limestone quarry where they constructed two Mix fire kilns. The quarry is destined to become for more than a half century the main production centre for the company.
1945 At the end of the second world war, Arturo Ghigliazza, supported by his nephew, Franco Accinelli, in plant project and construction activities for the lime industry, activities that have now become a successful industry. The family business is transformed into a limited company under the name of Brothers Ghigliazza SpA, meanwhile, the activities are developed in three production units (Finale Ligure, Genoa, Lucca).
1900-1920
1948
The children of Giacomo and Angelo, using the first experiences made in neighbouring France, developed the first and second kiln with coal combustion. The kilns are made of concrete and have a round section and a production of 20 T/D
The first kiln with fuel oil is constructed in Merano, Italy.
1920-1930 Under the supervision of Arturo Ghigliazza appointed the first team for the research and development of new technologies to be applied to lime production and quarrying.
1933 They applied for the first time the vacuum system with Venturi pipe called “Tyfoon� to the existing kilns with coal combustion, this increased the kilns production up to 30 T/D. They also created the first hydrator with casing made entirely of concrete. This innovations success is such that other lime producers request that they apply these technologies in their factories.
1935 Arturo Ghigliazza moved to Milan, a large industrial centre in northern Italy, to better follow the new technologies development and further their technical assistance work for the family company, he started project activities and lime plants construction for other producers.
1954-1955 Natural gas arrives in Italy. The first kilns are converted from coal to natural gas. These are the first steps that will lead to the birth of CBK kilns.
1964 The first kiln of 200 T/D. Is constructed under license of the American company Union Carbide (UCC) with fuel oil combustion, under the supervision of Franco Accinelli at the Brothers Ghigliazza SpA, a kiln of considerable size for that time.
1980 Following the oil crisis, new technologies for the combustion and the heat distribution in the lime kilns are developed that will lead to the acquisition of three industrial patents.
1981 Using the experiences made in the management for over 15 years with the UCC kiln and applying the patents relating to pulverized fuel combustion, they develope the HPK kilns that allow the use of low-value fuels reduce energy consumption by more than 20%.

1982
1997
Paolo Accinelli, after several years apprenticeship at the different production group units, was appointed vice president of Brothers Ghigliazza SpA and began to work at Società Impianti Calce Ltd in the project and testing department.
Società Impianti Calce LTD first, in the project field of lime equipment, obtained ISO 9001 certification.
1984 To complete the range of well-established single-shaft kiln technology SIC began the collaboration with a wellknown international partner for developement of double shaft kilns.
1998 The mills type "S" technology development led to the creation of the air separators type "HPS". This completes a revolution that leads to a new way to project the hydration plants.
2002
SIC supplied the first PCC plant in Mexico.
For the first time in Europe on behalf of Ciment Français/ Italcementi, a complete line with modern equipment was created for the production of hydraulic lime for bio-building.
1991
2004
Completed the study and testing phase, it began the production of the micronizer type “S” mills.
A new technical sales office was opened in Donetsk, Ukraine to enter a market in the Russian speaking countries.
1990
1995 On behalf of the national petrochemical Company ENI, one of the largest production plants for milk of lime for chemical use with a slaking capacity of 30 tons of CaO/h. was developed.
2007 A new office headquarters is constructed in Milan.
2009 From the joint venture with foreign partner the subsidiary company, STEELWORKS Ltd. is born responsible to carry out the fabrication and assembly of steel components. This new initiative will help to offer to the customers turnkey projects at a reduced cost for steel components, it offers the advantage to the customer a quality guarantee and one responsibility for the entire project.

MISSION We consider the customer our greatest fortune and our most important source of new experiences and ideas and our greater incentive to improve. We want our name is always synonymous with professionalism and in the lime world it represents the reference point. The timely and effective resolution to minor problems of our clients must find from all of us the same commitment we put in the execution of a major project. Our commitment to our customers should not be concluded with the performance tests signing, but this must be only the first milestone of a project and should represent the relationship beginning of a mutual growth.
We believe that designing a good plant it means exhaustively, creating a plant that respects the environment and it is safe for the health of those who must operate. The company property direct involvement in its management represents the guarantee for an immediate answer and to find a known and motivated partner to search the solution for the customer satisfaction.

is now a world leader in lime and its derivatives to project and construct plants and supply equipment and thanks to its wide experience, it is considered by its customers the “lime problem solving” or information source about the lime world. The new headquarters built in 2007, from initial project, is born functional to the activity that SIC develops and especially to the "philosophy" by which this activity can be achieved. The SIC “home” is located outside the city of Milan, one of the main technological and economic centres in Europe, the localization arises from the need to have access to all facilities that only a great international centre like Milan can offer. In the area of over 1000 m2 there are the offices, the technical & commercial department , the planning office, the research center, the laboratory for chemical and physical tests, the checking, machines testing and specialty materials area. The possibility to realise all the critical activities at "home", under the careful supervision of our qualified technical staff, may seem more expensive, but we want that all the functions considered strategic are concentred in our offices with a very short control chain and responsibility. We believe that the quality and the control bring together a great economic benefit in the project realisation to our customers and to SIC in terms of image return. The continuous similar technologies development, even if different for some their peculiarities, we want to ensure our customers that our proposal is always the result of a technological choice and not purely commercial.

COUNTER CURRENT SINGLE SHAFT KILNS In the single shaft kilns the heat exchange between the mineral and the heat source is counter current. These kilns main use, thanks to their low investment cost and their operation and maintenance simplicity, is in the small/medium lime production, when it is required a medium or low reactivity lime and when it is required a high CO2 content at the stack.

LIME MILK PLANTS The deep knowledge of the lime chemistry and physics, allows us to study and to realise plants for the lime milk and lime water production ‘tailored’ to the special needs of all chemical and industrial processes to which they are intended. The lime milk possible characteristics great variety obtained with our manufacturing processes, require prior to these equipments typology implementation a careful study by our technicians, in collaboration with the customer technologists, the production process to which the milk of lime is intended, to allow to accurately determine the necessary characteristics to its use. The theoretical assumptions of employment defined by the first analysis phase of the project, before moving to the stage of industrial design must then be verified by chemical and physical tests at a specialized laboratory. For this reason we created our own laboratory dedicated exclusively to the study of "the lime world” and that with the acquired experiences is an important facility available to our customers.
