Aggregate sites mostly process soils and rocks. Often, when processing soil, large heaps will contain covered rock masses, and there is a need to separate the two. This has always called for the use of screening to pre-process the material. With a scalper screen, it is possible to separate the large heaps of soils from the rock masses quickly and cost effectively.

​

Recycled concrete and limestone crushing processes also generate materials of different sizes. Here, it is often necessary to sort them for ease of use. For instance, the aggregate used in road surfacing are different to the aggregate laid in a foundation. Different buyers also prefer different aggregate sizes.

 

Scalping screens have revolutionized this sector. Sorting materials has become very cheap, making for a lower break-even point and more competition within the market.
