Peru is rich in mining resources, which is one of the 12 big mining countries in the world.There are mainly copper, lead, zinc, tin, silver, iron, and oil, etc. bismuth, vanadium reserves are the highest in the world respectively; copper reserve accounts for a third in the world; silver and zinc are ranked fourth in the world. Proven oil reserves are 400 million barrels and natural gas has 7.1 trillion cubic feet. Forest coverage rate is 58%, an area of 77.1 million hectares, which is the second only to Brazil in South America. Water and Marine resources is extremely abundant and so is fishery resource, fish meal production is ranked among the top of the world.in 2009, Mithril production is the world's highest, copper production is the world's second and so is zinc output; tin production is the third in the world and the gold production is the world's sixth.
So far, minerals containing tin have been more than 50 that have been discovered in Nature. The main tin ore is about more than 20 kinds. Cassiterite is the ore that has the most economic significance, followed by yellow tin. Some deposit, tin, lead, sulfur cylinder tin lead, tin, antimony, sometimes black silver tin, sulfur black boron tin, Malaya stone, water stone, water magnesium tin and other ores can be relative enrichment, which can also be formed industrial value.
As for so much economic significance of tin ore, tin ore mining plant in Peru is very popular. In tin ore mining plant, some mining machines are at demands, such as jaw crusher, cone crusher, impact crusher, grinding machines as well as some ancillary equipment. All these machines have their own characteristics. They are produced by shanghai SBM, a professional manufacturer and supplier of mining equipment, especially crusher machines and grinding machines.
Working principle of grinding machines: Material after crushed to the required size, the elevator will sent material to the storage hopper. Then through the vibrating feeder, material will be sent to mill host evenly and continuously. due to the centrifugal force effect when rotating, roller swing outward and press in grinding ring and then shovel knife scoop up material to the place between grinding roller and grinding ring, crushed by roller rolling. After grinding to powder, material with the wind circulation of blower is sent into analysis machine for sorting. The coarse material fall back for second grinding and qualified fine powder with airflow go into the finished product cyclone collection. The powder from the discharge tube is the finished product. In mill, grinding material has certain moisture content. When grinding, heat is produced, moisture evaporated.
Working principle of crusher machines: In the process of cone crusher work, motor through the driving device drives the eccentric set of rotating. Moving cone under the forced of eccentric shaft sleeve does rotary oscillation. Section in dynamic cone near static cone becomes a crushing cavity. The material under dynamic and static cone is extruded, impacted and broken for many times. When dynamic cone leave that section, material has been broken into the required size and material fall into the bottom of the cone under their own gravity. To be broken material from the inlet is sent into the cone crusher.
When clients choose these machines, you must be very careful, for many factors should be consider into the choice, such as hardness of materials, open pit quarrying site or not and so on.
