The grid bar spacing prior to the primary crusher is, therefore, a very effective way to enhance capacity within a plant, without compromising overall performance in any way. In addition to the scalping screen, a separate, small, two- or three-deck screen is a very useful inclusion for processing the 'unders' from the scalper.


There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.


Jaw Crusher vs Impact Crusher. In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine's chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even.
