Four Types of Aggregate Conveyors
Aggregate conveyors are typically used in mining and quarrying applications as well as at storage locations and for loading and unloading. They are sized for the required tons per hour and to fit the space available. For long life, high reliability, and low running costs, the conveyor should suit the type of aggregate being moved.
