In the metallurgical industry, chromite is mainly used to produce chromium iron alloy and metal chrome. Chrome ore and ferrochrome are used as additive material of steel to produce a variety of special steel with high strength, corrosion resistance, wear resistance, high temperature resistant, resistant to oxidation, such as stainless steel, acid steel, heat-resistant steel, bearing steel, spring steel, tool steel, etc.
In the metallurgical industry, chromite is mainly used to produce chromium iron alloy and metal chrome. Chromium metal is mainly used for smelting special alloy with the element such as cobalt, nickel, tungsten and so on. These special steel and special alloys are indispensable materials in aviation, aerospace, automobile, shipbuilding, and defense industry production of guns, missiles, and rocket and ship industries. On refractory, chromite is used to make chrome brick, magnetite chrome brick, and other special refractories. Chromite in the chemical industry is mainly used to produce sodium dichromate, and making other chromium compounds, which can be used in paint, textile, electroplating and leather industries, also production of catalysts and catalytic agent etc. Chromite is the shortage mineral in China, with fewer reserves and lower production and imports are more than 80% in the yearly consumption.
Since chrome ore can be made so many alloys and special materials, chrome ore mining plant has developed well in some areas that have rich chrome ore resources. In chrome ore mining plant, many mining machines are at demands, such as grinding machines, impact crusher machines, cone crusher machines, jaw crusher machines as well as some ancillary equipment.
Crusher equipment has many different types and all the types of crushers have different working principles, such as jaw crusher, impact crusher and cone crusher. Take the jaw crusher as an example, when jaw crusher is at work, activities slab has periodic reciprocating motion towards fixed jaw plate and it sometimes closes, sometimes leaves. When to close, the material is squeezed between the two plates, splitting, impacted and been broken. When to leave, materials that have been broken are discharged under gravity force from discharging mouth.
In the crushing plant, huge rocks need to be broken for several times into the required size. For this, crushing equipment has been divided into three stages in the crushing plant, such as jaw crusher for the first stage, impact crusher and cone crusher for the second or third stages according to the different hardness of materials. In the process of the huge stone broken into small stones, the first stage of crusher is usually the "primary" crusher. Jaw crusher has the longest history and also is the strongest crusher. For feeding into jaw crusher, material from the top enters into the crushing chamber that contains jaw teeth and jaw teeth with great force send material to the room wall, and these materials will be broken into smaller stones. Supporting jaw teeth movement is an eccentric shaft and the eccentric shaft is through the fuselage structure. Eccentric motion is usually produced by the flywheel that be fixed on both sides of the eccentric shaft. Bearings must withstand the huge impact loading, high temperature and abrasion sewage. Although the work environment is very harsh, jaw crusher still need to work very reliable. It is the key to guarantee the production efficiency.
