Aggregate - AfriSam

the crushing plant has a constant supply of raw material via conveyer belts. Crushing plant equipment settings are changed in response to the aggregate product required. The secondary crushers reduce rock particles further, after which the product is screened through different sized sieves to separate the particles into specific gradings.

11.19.2 Crushed Stone Processing

Quarried stone normally is delivered to the processing plant by truck and is dumped into a hoppered feeder, usually a vibrating grizzly type, or onto screens, 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.
