Galena is a common mineral, which is also called lead sulphide. It is an important ore mineral of refined lead, which is the most widely distributed. Galena is a kind of gray of lead sulfide. Before the Shang dynasty there were refined leads from the galena in China. They have metallic luster. Galena Often contains silver, therefore it also be used as the resources of silver. Galena becomes cerussite alum and lead after being weathered.
Galena is the main mineral to extract lead. The uses of lead are ancient and extensive, such as lead type printing, bag cable, steel lead tin alloy plating, defense, science and technology, pencil lead. Ancient Greek sailor used lead paint oil to removal the barnacle creatures in the ship bottom, etc. Lead has good corrosion resistance properties. With the lead paint, the ship is like wearing a layer of armor, magically ruled out algae, protected the ship bottom. Lead is essential raw materials for making weapons. Lead is also radiation material as shielding radioactive.
As for the large economic values of galena, in some area that contains rich galena minerals, galena mining plant is the main method to get refined lead from the galena minerals. In the galena mining plant, many mining equipment is needed, such as jaw crusher for the first stage crushing in the plant, cone crusher and impact crusher for the second or third stages crushing, grinding machines for other stages materials as well as some ancillary equipment. All these machines are produced by shanghai SBM, a professional manufacturer and supplier of mining machines, which is famous in the world. They mainly produce crusher and grinder machines as well as some other ancillary equipment for beneficiation. Theirbusiness has expanded to more than 170 countries in the world.
In galena mining plant, jaw crusher, cone crusher, impact crusher and grinding machines are necessary. According to the categories, crusher can be divided into medical stoner and mining crusher. Crusher refers to such crushing machine that discharging granularity that more than 3 mm is more than 50% in content of total discharge capacity.
Mine crusher is mainly used for all kinds of stone crushing. According to the different working principles and different particle size, crusher is also divided into many types. there are several types of commonly used crushing machinery such as jaw crusher, counterattack crusher, vertical impact crusher, hydraulic cone crusher, hammer crusher, roll crusher, compound crusher, cone crusher, double stage crusher, gyratory crusher, mobile crusher etc.
Cone crusher is suitable for the crushing of raw material in metallurgy, construction, road construction, chemical and silicate industry. It can crush all kinds of ores and rocks that are medium and medium hardness above. Cone crusher has many advantages, such as high efficiency, low energy consumption and product granularity and it is suitable for medium and fine broken of all kinds of ores and rocks.
Grinding machines are widely used in metallurgy, building materials, chemical, mining and other fields. According to the fineness of grinding material and discharged material fineness, mill can be divided into vertical pendulum pulverizer, hanging roller mill, high pressure micro powder mill, centrifugal mill, overpressure trapezium mill, three-ring medium speed mill.
Mill machine mainly consists of blower, the analysis of host, cyclone separator for finished product, plumbing, electrical machines, etc. The host consists of frame, the wind volute, the shovel, grinding roller and grinding ring, cover and the motor. Auxiliary equipment is jaw crusher, electromagnetic vibrating feeding machine; electric control cabinet etc. the user can choose machines flexibly according to the site condition.
Mobile impact crusher features heavy duty, fully remote controlled high production, and low maintenance.
SBM designed the YKN series vibrating screen, which has high-strength exciting force.
Belt conveyor with largest selection of standard and custom types are available from SBM.
HPC series hydraulic cone crusher with high efficiency is suitable for primary crushing of many kinds of mining, building construction etc.
Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa.
