Gneiss is metamorphic rock, it is derived from magmatic rocks, such as granites, and are formed from quartz crystals of feldspars and micas (same granite minerals, but with a different capability).
Often times it is characterized by oriented structure defined by different names, they may present a striated appearance.
Gneiss is stone with color ranging from light gray to dark gray to greenish-gray that alternates light areas with dark areas. The family also contains the Beola and Serizzo stones.
They are characterized by lamellar structure with easy divisibility in thick or thin flat slabs.
Gneiss is hard and resistant stone, and found a wide use is in road paving and structural elements of building. It is used for floors, walls and roofs, facade elements and as street stones. They are used for paving in gardens and for the traditional coverage of houses. In Interior design they are used for stairs, flooring, kitchen tops and bathrooms.
When blocks of gneiss, beola and serizzo have been prepared with sawn surfaces, they can be split with automatic H-frame machines with 4 blades, such as the P4 series, to be split in slabs with a small thickness.
The P4 Series includes machines for the processing of gneiss-serizzo-Beola, to get the split finished product of high quality thanks to the presence of bottom blades, top blades and also side ones. These machines are ideal to obtain slabs with a minimum thickness or particularly remarkable dimensions.
The Series MEC Fast falls within the category of machinery for cutting stone and concrete. This type of equipment is ideal for the cutting of irregular stone with high level of definition. The final effect on the block of gneiss-serizzo-beola has a high quality. In addition, productivity of equipment is increased and transportation costs of finish product are significantly reduced.
The two horizontal blades on the Half machine are capable for splitting in an automatic mode the blocks of gneiss-serizzo-beola: They have been designed, in fact, for the processing of veined materials. The material is split in half with in two distinct blocks with one split face and the other sawn.
The equipment of the Stark Series is able to recover the waste materials from the processing of blocks of gneiss-serizzo-beola, and to make them useful in building and landscape design. The jaw crusher Stark Series is available in three different versions to feed in the best way your requirements.
