Processing of Gravel and Sandworks

Abstract

No matter what kind of building activity is planned, be it houses, factories, roads, bridges, silos or just walls - gravel and sandworks are needed everywhere. In most cases desposits of raw gravel and sand contain impurities, and the extracted material must be processed to meet the quality requirements for building materials. Such impurities are mostly clay, loam, wood or coal. They can be removed by washing processes. It depends on the extent of pollution and the kind of pollution material, which process and which machine are to be applied.
