Shale is formed by the hardening of clay materials into tiny grains that are fissile and easily split into distinct formations. The composition is complex, with papyraceous or lamellar laminations. It splits easily into fragments when struck with a hard object. Shale is dense, with low hardness and dull surface lustre. Those containing organic matter are grey-black and black. Iron-containing shale is brown-red, brown-red, yellow, green and other colours. Shale has weak weathering resistance and often forms low hills and valleys in the terrain. Shale is impermeable to water and often becomes an impermeable layer or water barrier.
Shale is formed from clay material by compaction, dehydration and recrystallisation. Clay rock with a thin page-like laminated structure, called shale, is formed from very fine clay and mud, after compacting and consolidation, dehydration, and recrystallisation.
Different shales have different chemical composition indicators, and the chemical composition content of shales that exist in nature varies considerably. Generally, the Si02, content of shale fluctuates between 45% and 80%, the amount of Al2O3 fluctuates between 12% and 25%, the Fe2O3 content fluctuates between 2% and 10%, the CaO content fluctuates between 0.2% and 12%, and the MgO content fluctuates between 0.1% and 5%.
Shale Market Demand
The first country in the world to research and produce shale was the United States, which has been around for more than 80 years. The world-famous American skyscrapers were built entirely from shale raw materials. Subsequently, the Netherlands, Denmark, Belgium, Russia and other countries are widely producing and applying shale. Shale granule production in Beijing and Tianjin, Heilongjiang, Inner Mongolia, Jilin, Yunnan, Xinjiang and other places to develop faster, of which the development and construction of Heilongjiang is faster. But still can't meet the market demand, Qingan, Hegang and other places of the ceramic granule factory even appeared customer first payment after queuing up the phenomenon of material. This shows that the market demand for ceramic granules is very strong, the market prospect is broad.
Shale processing technology
Shale processing production process mainly includes: crushing, grinding, beneficiation three processes. Crushing process, three closed circuit crushing is more suitable for high hardness iron ore crushing, can complete the shale crushing and part of the dissociation work, thus improving the efficiency of the subsequent grinding; grinding process, two a closed grinding is a high efficiency grinding process, can make the iron ore grinding more fully; beneficiation process, in recent years, the emergence of a more successful new process is representative of the main:" Stage grinding ﹑ weak magnetic separation - anti-flotation process", "all magnetic separation process", "ultra-fine crushing - wet magnetic separation tailing process".
