Aggregate production: Fines generation during rock

2007-1-1  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.

Aggregate production: Fines generation during rock

Aggregate production: Fines generation during rock crushing. causes micro-fractures on new aggregate faces and generates a large amount of fines. The generation of fines increases when shear is imposed during crushing. Aggregates produced in current crushing operations show the effects of multiple loading conditions and fracture modes.

Size Reduction Characterization of Underground Mine

The production of construction and building materials starts with reducing the size of natural, industrial, and waste materials. In addition to strength and durability considerations of natural resources recommended by various institutions, size reduction characterization, specific to rock aggregates, has a vital role in their size-related quality.

A laboratory and full-scale study on the fragmentation

Rock fines produced in rock blasting and crushing processes is a major problem for aggregate producers. Laboratory and full-scale studies were carried out to explore the possible relationship between fines production and water content of rock material. The Brazilian tensile test was selected for the laboratory study while a cone crusher machine was employed for the full-scale trials.
