Crushing.
After extraction from the quarry, the raw materials needed for the cement production are broken in the pre-reduction plant.
Heavy trucks deliver the blocks of material to the feed hoppers of the crushing plant. The discharge device underneath the feed hopper then conveys the material at a controlled flow rate to the crusher.
Depending on the material's properties and the method of extraction, very different types of crushing plants are used for breaking the raw material.
Polysius installs crushers from renowned manufacturers, often using the products of our affiliated company ThyssenKrupp Fördertechnik.
