        • Aggregates

          There are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes. Processing these materials typically requires various steps including reduction and sizing and also may include dewatering and sorting. Producers can use a variety of crushing, screening, dewatering and conveying equipment to meet their desired specifications.
