Porphyry is a magmatic rock with abundant phenocrysts. The color is varied and changing and can run from red to brown, purple, from gray to green.
This rock is widespread in the North East of Italy, but also found in Mexico and Argentina.
This type of stone is often used for outdoor applications because it is a very resistant rock to cold and hot environments. It finds a wide range of use in various types of flooring (cobblestones, or slabs of different sizes) because of it’s roughness that makes it non-slip. It is also used in external cladding.
Given their technical and chromatic properties, some porphyries are widely used in the construction of architectural elements such as kitchen tops, window sills, stairs and pillars, as well as being widely used In gardening and landscape decoration.
Porphyry is also used in the aggregate industry for production of granules, or porphyry pebbles.
Usually porphyry is extracted in slabs in keeping with the natural quarry layer. It is worked on manual C-machines (for cubes, curbs …) and H-frame machines (for the production of stairs, steps or plates).
Featured with heavy-duty frame, STARK jaw crushers are ideal for crushing not only waste marble, granite and natural stone, but also a wide variety of different materials such as agglomerate, ceramic, glass, and concrete. STARK can produce different grain sizes depending on the opening of the jaws.
Ideal for recovering waste material, the Horizontal T1 is an automatic machine equipped with one splitting head that pitches sawn slabs, obtaining a split side in view face. The T1 version is suitable for those who do not need high volume production, since they work the slabs on one side at a time.
The Fast Series was created specifically as a line of machines for cutting shapeless stone, as in the case of andesite. These machines are, therefore, the ideal solution also for splitting and defining andesite. The Fast Series ensures reduced transport times and increased productivity.
