It is produced by calcining limestone (CaCO₃) at high temperatures (around 900-1000°C), releasing carbon dioxide (CO₂) and leaving calcium oxide in lump form.
The lump lime is then ground to the required fineness in a lime mill.
In terms of the percentage of active CaO, or calcium oxide, we produce the following types of lime.
White lime, CL 90-Q (R4, P1), very finely ground, is produced by calcining very pure limestone with a calcium carbonate (CaCO3) content of more than 97.5%. It is then ground to the required fineness. Due to its high chemical purity, high calcium oxide content, reactivity and yield, it is particularly suitable for the metallurgical industry, the construction industry (production of building products such as aerated concrete), road construction for soil stabilisation and environmental protection (flue gas desulphurisation and waste water neutralisation processes).
The white, quicklime, unquenched, very finely ground CL 90-Q (R4, P1) complies with EN 459 - 1. The quality management system is certified according to ISO 9001.
Bulk material can be transported by Raj wagons or tankers. Bagged versions are available in 25kg bags, pallets contain 1.2 tonnes. Lime must be protected from moisture during transport and storage. The permissible storage period is determined by the type of packaging and method of shipment.
Air-white lime, CL 80-Q (Rsv, P1), very finely ground, is produced by firing very pure limestone with a calcium carbonate content of more than 96 per cent. It is then ground to the required fineness.
Its properties make it particularly suitable for use in the construction industry for soil stabilisation and the preparation of hydraulic binders.
Air-white lime, unquenched, very finely ground CL 80-Q (Rsv, P1) is produced according to EN 459 - 1. The quality management system is certified according to ISO 9001.
Bulk material can be transported by Raj wagons or tankers. Lime must be protected from moisture during transport and storage. The permissible storage period is ten days from the date of dispatch.
