Emerald is a gem of davidsonite, which is the most outstanding members in the davidsonite family. Emerald is a beryllium aluminum silicate. Because that it contains trace of chromium hemitrioxide, it shows brilliant green with crystal clear. Emerald ore is often granular, massive, brittleness and its Mohs hardness is 7.5-8.As the formation geological conditions of emerald is most complex, specific and rare to get, it becomes a bigger precious raw materials for jewelry and decoration which value is bigger than the diamond, and has the appreciation.
No matter how precious of the ore, any of them can leave the mining. Like other minerals, emeralds are also mined ore from the primary ore, which is inseparable from the emerald mining equipment. Shanghai SBM has dedicated to the production of mining machinery and equipment research for years, the current range of products passed the ISO9001: 2000 international quality system certification standards. For emerald, SBM launched a series of processing equipment, including: emerald jaw crusher, emerald impact crusher, emerald cone crusher, emerald sand making machine, emerald vertical milling machine, emerald ultrafine powder mill and a range of emerald processing equipment. Currently, these SBM emerald mining equipment gradually dominate the market and sold more than one hundred countries and regions in the world.
Emerald is distributed in many countries and regions. Colombia is the world's largest high-quality emerald producing area, accounting for 70% of the world production. It is famous for its good color, good texture and large yield. The main two emerald deposits are Muzo and Chivor. Besides, in the Zambia, Zimbabwe of Africa, in the Australia of Oceania, in the Brazil of South America, all of them has produced emerald. Of course, in different regions, emerald ore processing equipment is different, especially in Colombia; the most common mining equipment is cone crusher.
In Colombia, cone crusher is the commonly used emeralds processing equipment. Depending on the material application standards, there are many kind of SBM emerald cone crusher, including: CS Cone Crusher, HPC Cone Crusher, HCS Cone Crusher, PY Cone Crusher and so on. All of them are suitable for the crushing of emerald. Most of them use a hydraulic cylinder in the lower part of its center to provide overload protection and discharging mouth adjustment. At the same time, it is self-adjusting when clear the cavity.
With the advantage of chamber clearing control system, manganese wear parts, highest reduction ratio, high capacity and yield, low maintenance requirements, less downtime, SBM emerald cone crusher show a good performance in the emerald primary crushing, emerald secondary crushing, emerald tertiary crushing and fine crushing. There are 4 models available and the finished product grain shape can be adjusted by the tailor-made adjusting device. Therefore, cone crusher became the most important emerald mining machine.
Colombian emeralds process has a long history. Because the emerald ore is more brittle and hard, the native emerald ore also requires a series of processing. The first is crushing, using primary jaw crusher to process emerald ore into 20-50mm, using intermediate impact crusher to process emerald ore into cubes between 10-20mm, using fine cone crusher to process emerald ore into 3-10mm and keeping the three aspects in turn. The second is grinding. Depending on the grade of the emerald ore, the high purity can be directly used in the production. For the low purity, one method can be made into powder for the mineral separation to remove impurity; the other method will compresses the low grade ore to the desired emerald decorative or industrial materials at high temperature and pressure.
Currently, no matter in which country, SBM can analyze the local stone and the local mineral resources to provide you with a customized mineral production line. These customized mineral production lines is divided into ore crushing production line, ore grinding production line, sand making production line and ore dressing production line. In addition to processing emerald ore, these lines can also process any materials which Mohs hardness is below 8. In Colombia, SBM emerald mining production line includes: Emerald vibration feeder, emerald jaw crusher, emerald impact crusher, emerald cone crusher , emerald vibrating screen, emerald mill and other equipment and with the equipment of dust removal, convey and beneficiation.
