Aggregate manufacturing typically starts by blasting rock masses and is followed by a series of crushing stages. Comminution in typical hard rock quarries is sketched in Fig. 1.ASTM particle size distributions of select aggregate products are also shown in Fig. 1 ().Crushing operations can accommodate some adjustment to match the demand for each gradation.
Rock from the quarry face is fed into the top of the crusher and crushed rock falls out of the bottom of the jaws. The size of the crushed stone which passes through the jaws is partly governed by the gap set at the bottom of the jaws, though larger size rocks can pass through if the rock being crushed is slabby or elongate in shape. Large scale gyratory crushers can also be used.

Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. the rock has been crushed into various sizes, in quarrying activities; during the process the dust generated is called quarry dust and it is formed as waste. Therefore, quarry dust
crushed rock aggregates. During the aggregate production process, large volumes of mineral residues are generated, mainly as fine-grained materials, which in most quarries are either stockpiled on site or transferred away from the quarry for disposal at waste sites. If beneficial use could be found for these ‘quarry dusts’, which
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
