The vacuum residue of petroleum is cracked and coked by a coking device at 500 to 550°C to produce black solid coke. Its appearance is a black or dark gray honeycomb structure, and the pores in the coke block are mostly oval and interconnected.

Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite electrodes and certain special carbon products; in the steelmaking industry, needle coke is an important material for the development of new electric furnace steelmaking technologies.
Medium sulfur, ordinary cooked coke is widely used in aluminum smelting.
High-sulfur, ordinary green coke is used in chemical production, such as manufacturing calcium carbide, silicon carbide, etc., and is also used as fuel for metal casting.
With the rapid development of my country's cement, electrolytic silver, steel and thermal power industries, the demand for low-sulfur petroleum coke has increased sharply. However, with the increasingly stringent environmental protection policies, the use of high-sulfur petroleum coke has been greatly restricted. Therefore, my country's petroleum coke market will face a shortage of low-sulfur petroleum coke and a serious surplus of high-sulfur petroleum coke in the future.
It can also be used as fuel, but when used as fuel, a graded impact mill is required for ultrafine pulverization. The coke powder can only be burned after being made into coke powder through the equipment, and the coke powder is used as fuel.
Crush 200-300 pieces of petroleum coke to 70-80 pieces to ensure combustion particle size.
This machine is composed by frame, gear roller, transmission device and gear roller gap adjustment device and so on. Adopting alternating current motor to drive the coarse broken tooth roller on the both sides by the strong triangular belt respectively, so that the coarse broken tooth roller rotates in opposite directions. After the material enters the crushing chamber from the inlet, the two coarse roller is broken by a variety of different combinations broken which are rotated at a high speed, the partical size can be reach to around 6mm after fine broken, the size of particle size can be adjusted by fine teeth roller gap to complete.
