Cone crushers tend to produce more elongated particles because of their ability to pass through the chamber unbroken. In an impact crusher, all particles are subjected to impact and the elongated particles, having a lower strength due to their thinner cross section, would be broken (Ramos et al., 1994; Kojovic and Bearman, 1997). 6.5.1. Hammer ...
The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms …
Granite one of the stones that is hard, abrasive and with high compressive strength, and it needs jaw crusher or gyratory crusher to make a primary process. ...

Crusher Run; Dense-Grade Aggregate (DGA) Dirty stone; Shoulder stone ¾ Blended Stone Now that we have looked at several of the most common types of crushed stone let's look at some common types of gravel. Types Of Gravel Gravel is often used for aesthetic purposes, while crushed stone finds its place more often as a construction material.
Of course, there are also different styles of rock crusherspression-style jaw and cone crushers, for example, fit into the various stations in a crushing circuit (depending on factors like the sizes, varieties, and hardness of the rock you need to crush, as well as the necessary output).
REMco ST/AR VSI crushers are rock-on-anvil vertical shaft crushing machines designed to operate as second, third or fourth stage crushers for processing soft to medium/hard rocks, ores or minerals that contain less than 15% abrasives (silica, alumina, and iron).
