Taking the granite sand making line as an example, the crushing process is as follows: 1. Coarse (primary) crushing: Bulky granite rocks are evenly fed into the jaw crusher by the vibrating feeder. 2. Secondary crushing: The coarsely crushed granite stones are sent to the cone crusher by the belt conveyor. 3.

2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio. Adopting Gupta and Yan [5] the power is given by, P = Q.R d.w i where Q = crushing capacity, Rd = reduction ratio (x 1 /x 2) and wi = work index. In this work Q = .356 t/hr and x 1 = 7.5mm. A roll gap of 5mm had already

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
