The benches are then drilled and break up into blocks. The concluded blocks on common are 10'x6'x6' and can weigh as much as forty tons. Blocks are inspected for any cracks, major flaws and for coloration range.

Transportation from the quarry to the processing plant is varied depending on the place of the quarry. From our desert quarries in Namibia, several of the blocks trucked 1200 miles to our plant in South Africa. Other blocks are despatched by truck to the port of Walvis Bay, Namibia and then transported by ship to Italy for processing. Upon arrival at the processing plant, blocks are selected for cutting. Making use of forty ton Gantry Cranes, the blocks are positioned on large 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 big carriage up to 18' extensive. Pushed by electric powered motors the carriage is pushed and pulled again and forth. Even though the blades are relocating, a slicing slurry comprised of metal grit and water is poured above the blocks to supply the abrasion for the chopping.

Completion of the block chopping calls for among 2-seven days (based on the hardness of the stone). The good quality of the slicing is dependent on the skills of the gang observed masters who are in demand of the chopping. Because of the variables in stone hardness, density, the slurry, blade tensioning, and chopping velocity, the sawing method needs constant monitoring by the masters. The tough cut slabs are then completely cleaned with water and well prepared for the following phase of processing.

The following section is decided by the specific variety of stone. Numerous of the granites quarried today go via an epoxy procedure to improve the top quality of the stone. For case in point, the massive quartz crystals discovered in some granite have fissures or crazing to them. The reality is, if there weren't fissures it would not be quartz. These qualities are inherent to that mineral. These fissures are not defects, as we say in the stone market, "Mother Character doesn't make mistakes". Nevertheless, with today's epoxy engineering, a increased assortment of exotic granites can be processed for countertops.

The epoxy process begins by loading the slabs into an oven to completely dry the stone and provide it to an even temperature ahead of the epoxy is used. Epoxy resin is poured and then troweled on in a skinny layer in excess of the complete surface 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 extremely challenging coating.

The sharpening process is the identical regardless of whether a slab has been epoxied. The polishing line is a lengthy conveyor-fed machine which sends the slabs under 21 independent grinding, then sharpening heads. But even with the numerous processes that are associated, normal stone remains quite competitively priced. In many circumstances it is priced lower than sound surface items, even however sound surface is made at a fraction of the value.
