Processing of natural stone

Optimal material preparation

When processing natural rock, larger rocks are broken up into defined grain sizes in a multi-stage crushing and screening process.

Mobile crushers

If the rock is processed in mobile plants, excavators transfer the blasted rock to crushers which are usually located directly alongside the quarry wall. The crushed stone is then either transferred directly to the next processing stage on conveyor belts or removed by trucks. Alternatively, the broken material can also be removed by heavy-duty trucks. Excavators or wheeled loaders load the rock onto trucks at the quarry wall for transport to the stationary processing plan

Different crushing techniques

Crushing techniques distinguish between pressure crushing and impact crushing. Jaw crushers or cone crushers use the so-called pressure crushing technique where material is reduced in size mainly by high pressure between slow-moving wear parts. Impact crushers use the so-called impact crushing technique, in which the rock is accelerated by a massive fast-moving rotor and reduced in size by impacting against breaker walls. Jaw crushers are widely used for crushing medium-hard to hard rock, and are mostly used as primary crushers. Impact crushers work as both primary and secondary crushers for processing soft to medium-hard rock, producing larger quantities of fines. Cone crushers are used predominantly as secondary crushers for hard rock.

Manufactured by the WIRTGEN GROUP in India, to be precise in the local production and assembly plant in Pune, the mobile screening plants in the MOBISCREEN EVO line are successful all over the world.

Job Report

In the north of Vietnam lie the emerging city of Lang Son, located on the border with China, and National Route 1A, the heavily congested motorway to the capital, Hanoi: a KLEEMANN plant combination was brought in to eliminate this bottleneck.

Job report

A MOBIREX impact crushing plant keeps the transport routes in Beijing short and converts excavated tunnel material into first-class raw material.

Job Report

Asfaltbolaget, with its head office in Karlskrona, is a Swedish asphalt, road and landscape construction company. After all of their positive experience with WIRTGEN GROUP, it stood to reason to include crushing and screening plants from KLEEMANN in their short-list.

Job Report

It was no longer economically viable to put the existing stationary plant back into operation. The Polish company Dolata therefore decided on a plant train from KLEEMANN.
