Manufacturing of aggregates

The commercial aggregates are processed from a range of geological rock types, including granite, dolomite, quartzite, dolerite and amphibolite.

:: Production and crushing process

The production of aggregates and sands starts with the drilling and blasting of the rock to produce rock on-ground.

Once the rock has been blasted, it is loaded onto dumper trucks and transported to a crusher for the initial (primary) crushing. During the primary crushing, particles ranging in size from dust to 450 mm are crushed to more suitable sizes.

The next steps are secondary and tertiary crushing (shaping) and screening of the aggregates and sands into the required fractions.

Aggregates are classed as coarse products with a particle size > 4.75mm and sands are defined as fine products with particle sizes of less than 4.75mm.

All processes are continuously monitored to ensure the end product meets relevant specifications and the requirements of our customers.
