What is marble
Here are two stones. The one on the left is granite, and the one on the right is marble. Different types of stones require different quarrying methods and the machines used for quarrying are also different. Buying the wrong machine is the biggest waste.
If you're a boss planning to quarry marble, then this video is really worth watching. It will directly influence your decision on "which machine is the most suitable for quarrying marble". This video mainly includes:

(1) What is marble
Marble is a type of metamorphic rock. It is mainly formed when limestone or dolomite undergoes high - temperature and high - pressure processes. Limestone and dolomite were originally carbonate minerals deposited in the ocean. When crustal movements bury these rocks thousands of meters underground, under high temperatures above 150 - 200℃ and strong pressure, the internal structure of the rocks changes. The mineral grains rearrange and recrystallize to form a dense granular structure. At the same time, impurity elements like iron and manganese remaining in the rocks form stripes or patches. This metamorphic process usually occurs in areas where tectonic plates collide or where there is frequent magma activity, and it can take millions of years. The finally formed rock is hard in texture and can be polished to have a smooth surface. Its patterns and colors depend on the composition of the original rock and the metamorphic conditions. Later, through crustal movements, these marbles emerged from the seabed, forming mountains and being exposed on the earth's surface, which gives humans the opportunity to quarry them.
(2) The uses of marble
As high - quality natural stone, marble is widely used in architectural decoration, sculptural art, and high - end home furnishings. Its unique texture and luster make it the top choice for indoor and outdoor wall and floor paving, countertops, and columns. For example, in palaces, museums and other landmark buildings, it is often used to create an elegant atmosphere. In the art field, the pure white and fine - grained marble for sculpture can be carved into delicate works. In terms of economic value, the global marble industry chain includes quarrying, slab processing, carving manufacturing, and international trade. High - quality varieties such as Italian Carrara White and Chinese Han White Marble can cost thousands to tens of thousands of dollars per cubic meter. Medium - and low - grade marbles meet the basic demands of the building materials market. At the same time, they drive the development of related industries such as stone machines and maintenance products, forming a complete industrial economic system.
(3) How to quarry marble
Marble is a metamorphic rock. It has a medium hardness but is quite brittle. Traditional blasting or mechanical impact can easily cause the expansion of internal micro - cracks, damaging the integrity of the stone blocks. Moreover, marble ore bodies often have natural cracks and discoloration. Therefore, when quarrying marble, these cracked and discolored parts must be avoided to maximize the yield of usable stone.
For these reasons, the method of using a wire saw machine to cut high - blocks has stood out among many quarrying methods. The wire saw machine uses a static cutting process (grinding with diamond beads). There is no vibration and no impact force transmission, which can avoid internal damage to the stone and ensure the yield rate. By closely combining with drilling equipment, first drill holes, then thread the rope, and then start the machine for automatic cutting. This has become an irreplaceable solution for marble quarrying. More detailed content will be shown to you one by one in subsequent videos.
