second hand complete granite quarry machine
Stone quarrying and processing activities have recently been involved in an impressive technological progress characterized by the introduction of advanced cutting methods, the use of powerful material handling equipment, the improvement of stone working machinery and the application of sophisticated management tools, resulting in a spectacular increase of productive parameters accompanied by a substantial improvement of the material quality.
At the same time, pit geometry (size of the faces, extension of the working areas), quarry design, plant lay-out and operations management (optimization of the working cycle), were adapted accordingly, availing of a better technical knowledge and of higher manpower skill.
Granite Quarry Method
Several options are available for mining out a granite deposit. The quarry technique depends on material property, the shape and size of the geologic formation, the topography of the àite, the overburden thickness, the location of the quarry, the production level and the imposed restrictions. Concerning the drilling-based methods, considerable progress has been made in the development of the drill machines themselves and of the supporting and guiding structure.
The choice between them depends essentially on the drillhole requirement. In most Italian quarries, where the incidence of drilling on the unit product is moderate (less than 20 m of hole per m3 of commercial block, final shaping included), simple equipment, easy-to-operate, is still generally preferred.
