It is called the facilities where stones and rocks of different sizes are crushed into small pieces.

Material used in many road construction events; It was formed by the erosion of water on the sea and stream sides.

The pebbles are kept ready for use after many sieving processes have been passed over them according to their structure in the factories.

3 products are obtained from the crushing-screening plant. They are not different from each other in terms of chemical properties, there are physical changes. These changes create a different size product scale. These three products are called stone dust (0-4mm), number 1 stone chips (4-11mm) and number 2 stone chips (11-22mm).

1 product is obtained from the sand plant. When they cannot be processed in crushing and screening plants, they are brought to this plant. After being purified from waste clay with a feed size of 0-20mm, it takes its place in the product scale as washed sand (0-4mm) and goes through the grinding process. As a fine aggregate, its difference from stone dust is that the amount of very fine material in it is controlled and the percentage of passing through 1 mm is higher.
