Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface.
Asgeir Kvitvik, Plant Manager (AK): The Kjøpsvik plant began life as Nordland Portland Cementfabrik, which was founded in 1918. There were three main reasons for establishing the cement plant here. Firstly, there is a limestone deposit that is 'ready-mixed' for cement. It has the correct proportions of calcium, silica, iron and alumina.
Our agricultural lime plant is fully automated, and the technicians in our on-site lab constantly test gradation and calcium content to make sure materials meet quality guarantees. Our plant is capable of producing any size product from 1/4″ down to a superfine material that doesn't need to be burned in a kiln.
