Granite - From the Quarry to Your Kitchen
Normal stone quarries are found throughout the world. Every continent has its very own distinct rock kinds and shades. Through a approach of prospecting and researching geological surveys, websites are picked for their framework, shade and marketability. These web sites might be located in very distant locations such as Madagascar, The Amazon area of Brazil, or in the desert area of Namibia, positioned on the continent of Africa. As soon as a internet site is chosen, and mining licenses are obtained by pursuing stringent environmental recommendations, quarrying commences.
Subsequent the granite should be extracted from the earth. Extraction is a approach of drilling and wire sawing to launch massive benches of stone. The benches are then drilled and break up into blocks. The completed blocks on average are 10'x6'x6' and can weigh as significantly as 40 tons. Blocks are inspected for any cracks, major flaws and for shade range.
Transportation from the quarry to the processing plant is different based on the place of the quarry. From our desert quarries in Namibia, a lot of of the blocks trucked 1200 miles to our plant in South Africa. Other blocks are sent by truck to the port of Walvis Bay, Namibia and then transported by ship to Italy for processing. On arrival at the processing plant, blocks are chosen for chopping. Employing 40 ton Gantry Cranes, the blocks are positioned on huge trolley carts and pulled under the gang saws for chopping. The gang saws are tremendous machines. The huge blades are aligned and spaced on a huge carriage up to 18' wide. Pushed by electric motors the carriage is pushed and pulled back again and forth. Whilst the blades are transferring, a cutting slurry comprised of metal grit and water is poured over the blocks to offer the abrasion for the cutting.
Completion of the block slicing calls for amongst two-seven days (dependent on the hardness of the stone). The top quality of the reducing is dependent on the expertise of the gang noticed masters who are in demand of the chopping. Due to the fact of the variables in stone hardness, density, the slurry, blade tensioning, and chopping speed, the sawing method demands constant checking by the masters. However, with today's epoxy technologies, a better variety of exotic granites can be processed for countertops.
The epoxy procedure commences by loading the slabs into an oven to entirely dry the stone and deliver it to an even temperature prior to the epoxy is used. Epoxy resin is poured and then troweled on in a thin layer more than the complete surface area of the slab. Slabs are then rolled into a vacuum chamber drawing out any air pockets so the epoxy can penetrate deeply into the slabs. The epoxy is then oven cured into really challenging coating.
The sprucing process is the identical no matter of no matter whether a slab has been epoxied. The polishing line is a prolonged conveyor-fed equipment which sends the slabs under 21 different grinding, then sprucing heads. The polish is reached by a series of grits on rotating sprucing heads beginning from a extremely coarse 60 grit diamond abrasive to 1800 grit sprucing bricks.
