Application Of petroleum coke
Petroleum coke is a byproduct of the oil refinery industry. Petroleum coke refers to all types of carbonaceous solids obtained in petroleum processing, which includes green or raw, calcined and needle petroleum coke. Petroleum coke is used in many applications, including electrodes and anodes. It is also used as a fuel in the metal and brick industries.
Fuel
Petroleum coke is a material relatively low in cost and high in heat value and carbon content with good chemical stability, making it an efficient and cost-effective fuel for producing metal, brick and related products. Because it is mostly elemental carbon, it burns without contaminating materials it's heating.
Graphite Electrodes
Graphite can be produced from low-sulfur needle petroleum coke, which must be heated above 5,432 degrees Fahrenheit. Graphite is used in the production of electrodes for electric arc furnaces used in the steel-making industry. The performance of these electrodes depends on the quality and purity of the petroleum coke used. Graphite electrodes are highly demanded in the steel-making industry, because of their low coefficient of thermal expansion, which is related to the capacity of resisting high temperatures.
Anodes
Calcined petroleum coke, often low in sulfur and metallic impurities, is used to make anodes for the smelting industry. These anodes must be dense, strong, electrically conductive, and of high carbon purity, says Surinder Parkash in "Petroleum Fuels Manufacturing Handbook." Calcined petroleum coke is mixed with coal tar pitch in the production of anodes. Calcining is a high-temperature heating process used to eliminate the volatile materials left during the production of raw petroleum coke.
Which equipment that petroleum coke powder processing needs?
Firstly,we should determined the finished product range according to the application. Under normal circumstances,if the fineness is 200 mesh or so, you can use raymond mill; if the fine degree between 325-3000 mesh, we need to use micro powder mill. The output fineness determines the selection of specific production process. The entire production line include two links of crushing, milling. If the particles are small,we can use milling production process directly.
Pre-set production line can mainly use coarse crushing, and the finished product fineness is below 3-5cm for milling production processes. Feeding device is composed by a fully enclosed vibrating feeder, conveyor belts and elevators and relative access, the next is raymond mill or ultra-fine grinding mill to complete powder processing stage. Due to closed systems, the benefits that can be recycled and processing, powder particle unqualified return to grinding equipment, processing again, greatly improve the production capacity. The entire mill production line can work for a long time, the finished petroleum coke particle fineness is uniform with high quality. And it achieve the purpose of efficient and environmental protection production.
The difference between petroleum coke micro powder mill and petroleum coke Raymond Mill
The difference between petroleum coke micro powder mill and petroleum coke Raymond Mill is that the Finished Sizes and yield, micro powder mill product fineness can reach 300-3000 mesh, yield about 0.4-30 tons per hour, and high pressure Raymond mill Finished Size only reach 350 mesh, but production can reach 20 tons per hour, compared to see individual requirements,you can shoose the suitable model.
