Companies | Mining in the Nordics

Mining and aggregate processing equipment operates continuously under harsh conditions creating constant maintenance concerns. Abrasive environments that include dirt, dust, grit and humidity place extraordinary demands on conveyor belts and drive units. Heavy loads and impact shock intensify these assaults on the entire conveyor system.

What Is Concrete Rock?

Concrete is an aggregate consisting of large chunks of material in a concrete mix, ... but some of the most common types of rock used to make aggregate are limestone, granite, quartzite, and gravel. Aggregates are the most heavily mined materials in the world, and for good reason.

Quartzite: Metamorphic Rock

Quartzite is valued as a raw material because of its high silica content. A few unusual deposits have a silica content of over 98%. These are mined and used to manufacture glass, ferrosilicon, manganese ferrosilicon, silicon metal, silicon carbide, and other materials. Decorative and Gemological Use
