Iron ore crushing and screening plant needs many mining equipment. And there are many mining equipment manufacturers and suppliers in China. Among these plenty suppliers, shanghai SBM is an excellent supplier after through many years test in the world.
PCL vertical shaft impact crusher is the first generation with international advanced level of energy consumption of sand making machine, which is our experts' years wisdom and correct decision-making of developing sand equipment. Its performance has played an irreplaceable role in all kinds of ores and fine crushing equipment.
It has various installation modes and flexible. On the production process, stone can be formed to protect the fuselage bottom, which makes the machine durable and without wearing.
Commercially Available Iron
Commercially available iron is classified based on purity and the abundance of additives. Pig iron has 3.5–4.5% carbon[59] and contains varying amounts of contaminants such as sulfur, silicon and phosphorus. Pig iron is not a saleable product, but rather an intermediate step in the production of cast iron and steel. The reduction of contaminants in pig iron that negatively affect material properties, such as sulfur and phosphorus, yields cast iron containing 2–4% carbon, 1–6% silicon, and small amounts of manganese. It has a melting point in the range of 1420–1470 K, which is lower than either of its two main components, and makes it the first product to be melted when carbon and iron are heated together. Its mechanical properties vary greatly and depend on the form the carbon takes in the alloy.
The material from the hopper into the impact by the distributor is divided into two parts. One part is composed of the distributor intermediate into the high-speed rotation of the impeller, the impeller was rapidly accelerated, the acceleration of up to hundreds of times the acceleration of gravity, and then to 60-70 M / s velocity from impeller a uniform flow in the projectile out, first of all by the same distributor around since the receipt of a portion of the material impact of falling is broken, and impact to the vortex branch cavity material lining layer, is material lining layer rebound, oblique impact to the vortex chamber at the top, it changes its direction of motion, partial to sports, emitted from the impeller material the formation of continuous material curtain. Such a piece of material by crushing cavity two times that many probability impact, friction and grinding crushing effect in vortex. The crushed material is discharged. In the process, material mutual self-impact broken, do not directly contact with metal components, but with material lining layer of impact, friction and grinding, which reduces iron pollution, prolong mechanical wear time. Vortex chamber internal clever air circulation, eliminate the dust pollution.
