Outline on Granite Cutting
The word “Granite” is a derivative of a Latin word “Granum” that suggests “grain. Because of coarse or grainy nature, granite is called by this name. Granite occupies an important place among the stones with dimension. Its qualities of hardness, resilience, potentiality enable stone to get mirror polish and charming colors.
The Application of Granite
Most common applications of granite are in the manufacturing of blocks and slabs for the building construction sector.
Block sizes may differ with differences of deposit. The most common block size is 22 tonnes of a size approximately 3.0m x 1.5m x 1.5m.
Though blocks 6 tones and most 11 tones might be created.
22 tones sizes are generally the largest.
Supply of Granite in the Past and the demand of the Present
The long lasting features and beauty are the guiding requirement of architecture ages after ages. Granite that is made of minerals, yield too much protection against scratches. This feature has made the material very much thing of choice.
The buildings made of granite are chosen for their beauty, stability, durability and prestige. Granite is also used in floor tiles, tumble stones, landscape products, building interiors, church features, materials for paving, slabs for counter top slabs, graveyard features, and paved in other industrial applications. Granite products are found in diverse finishes and color.
The demand of granite is generally connected with the construction engineering the and in particular the building sector.
Granite Production Process
The flourishing and cost-effective functioning of granite quarries mostly depends on a rapid functioning of the structural knowledge of the rock and its usual sharing out among the masses. Not only has that it also depended upon enhanced application of tools, methods, and equipments for quarrying. The exact geographical location of the quarry and facilities for moving are also important factor that affect the fruitfulness, and also to a great extent transform the real cost of operations in a particular place.
The process of manufacturing of granite slabs and blocks involves the process that follows:
- Quarry opening
- Blasting
- Cutting
- Polishing
- Ornamenting
The Granite Specialized method of Extraction
The quarrying of big dimensional stones needs a particular process of drawing out. Normal methods of quarrying use huge explosives for moving and breaking the vast degree into an aggregate. This generates crack all through the stone that turns it into inappropriate for the use. The over use of explosive has turned many quarries useless.
The Process of Granite Sawing
For primary block extraction wire sawing is used that consists of a long trapped wire or diamond tilted wire attach through a serialized of pulleys and assisted by abrasives. Stranded wire has been used for many years in marble and sandstone, whilst improvements in diamond technology, has seen the recent introduction of wire sawing in granite quarries.
Gang saw granite slabs
Wire sawing is used for major extraction of block. But, the cutting is carried out by a gang-saw for generating gang-saw granite slabs. By using a reciprocating frame Gang sawing is done up to 120 steel made blades functioning through the block.
It might need a week or so to saw each block of granite. But, cutting of granite has no adverse effect on the environment.
