Raw material introduction:

Marble is a metamorphic rock formed under high temperature and pressure of the earth`s crust. The crust internal forces lead qualitative changes to all kinds of rocks, which refers to changes on the structure and composition. Then the original rocks become metamorphic. Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main ingredients are calcium, accounting for more than 50%. And there are also magnesium carbonate, calcium oxide, manganese oxide, silica and so on. Generally marble contain impurities and calcium is easy to become weathering and dissolution due to the carbon dioxide, carbides and vapor in the air, thus the marble surface tends to lose luster before long. Besides, when compared to granite, marble has relatively softer nature.

Marble processing technology:

Marble crushing equipment combines the advantages of the hammer crusher and impact crusher and gradually gets to replace the original vertical impact crusher in the machine-made sand market. It has the following features and advantages: Based on the principle of “stone hit stone thus crushing”, it`s equipped with a huge curved crushing chamber, which is screening one with a grate seam. The most important is the special crushing hammer, which achieved a revolutionary breakthrough of “hammer crusher as jaw crusher”and thus totally realizing the crushing machine`s operation at a low cost. While, the vertical impact crusher discharge can not be adjusted and its spindle speed is very fast, thus leading to high maintenance costs. Usually once a problem occurs, only Depot Repair can solve it. Also in the final products, there will be a large amount of powder. And the material yield is low, accounting for only 30% -40%. Besides, with dual-motor driving, it needs high power consumption, which is twice and even more as the crushing machine.

Marble Application:

Marble has beautiful colors and patterns, together with high compressive strength and good physical and chemical properties. And it`s widely distributed and easy to process. Along with economic development, marble`s application range and amount keep expanding, thus playing an important role in people's live. Especially in recent years with the massive marble mining, industrial processing and its international trade, large quantities of marble decorative plates have been used in the building decoration industry, not only for luxury public buildings but also home decor. Marble is also used extensively to make exquisite items such as furniture, lamps, smoking set, artistic carvings and so on. Some marble (including limestone, dolomite, marble, etc.) can also be used as alkali materials. Also the marble mining and processing may generate many broken stones and leftovers, and they are usually used in the production of artificial stone, terrazzo, stone rice and powder, which can act as filler in paints, plastics, rubber and other industries.
