Processing Techniques
Feeders are necessary to deliver a uniform flow of aggregate fractions among storage, handling, and processing equipment. They are vital where principal operations are interrupted by a storage step. Feeders provide a reduction in wear and tear, abrasion and segregation as well as the help in dust control.
