AP-42 Section 11.19.2 Crushed Stone Processing and ... - EPA

PM-10 emissions if uncontrolled. Quarried stone normally is delivered to the processing plant by truck and is dumped into a bin. A feeder is used as illustrated in Figure 11.19.2-1. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher.
