The production process of graphite electrode is mainly the production process of petroleum coke raw material powder. The amount of petroleum coke raw material powder used in stone mill electric shock production is large, so this article mainly introduces the production process of petroleum coke powder. Kolirick can provide graphite vertical mill, carbon-specific vertical mill (including carbon mill, petroleum coke mill or forged petroleum coke vertical mill) and other grinding equipment in this process.

1. Production process of graphite electrode manufacturing
Graphite electrode is mainly processed by graphite electrode vertical mill, petroleum coke and needle coke as powder, coal tar as binder, through calcination, seasoning, mixing, pressing, roasting, graphitization and machining. The electric arc furnace is a conductor that heats and melts the charge by releasing electrical energy through electric isolation. According to its quality standards, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode.
2. Graphite electrode production process: petroleum coke powder production process:
In the manufacturing and production process of graphite electrodes, the production process of petroleum coke powder is an important part of the early preparation and production process. The production process of petroleum coke powder can be carried out by a graphite electrode vertical grinder. The actual production process of petroleum coke powder is as follows:
The production process of petroleum coke powder grinding includes four steps, from the crushing of calcined petroleum coke to the packaging of finished products, each step is closely integrated. The actual powder making process is as follows.
(1) Crushing of calcined petroleum coke
The first step of the petroleum coke grinding production process - crushing. Large pieces of calcined petroleum coke are crushed by a jaw crusher to particles with a particle size of less than 40mm and stored in a storage tank for reservation.
(2) Forged petroleum coke powder grinding
The second step of the petroleum coke powder grinding production process - grinding. The crushed calcined petroleum coke particles are evenly fed into the vertical mill or ball mill by a quantitative feeder and ground to about 200 mesh.
(3) Classification of calcined petroleum coke powder
The third step of the petroleum coke powder grinding production process - classification. The ground calcined petroleum coke powder is sent to the powder classifier above the vertical mill through the hot air at the bottom of the vertical mill. If the particle size meets the standard, it will be collected by the dust collector, and the coarse powder will fall back onto the grinding disc of the vertical mill and be ground again until it can pass the powder classifier.
(4) Collecting calcined petroleum coke powder
The third step in the petroleum coke powder grinding production process is collection. The forged petroleum coke passed through the powder selector is sent to the dust collector by the warm air generated by the hot air furnace, and then sent to the silo or packaging machine through the conveyor to complete the production process of petroleum coke powder grinding.
xingaonai can provide the petroleum coke powder production process in the graphite electrode production process. The use of graphite electrode vertical mill and carbon special vertical mill (carbon mill, petroleum coke grinding equipment - mainly petroleum coke vertical mill and other equipment) has the advantages of low energy consumption, high product purity, continuous operation, large capacity adjustment range, low noise, less equipment maintenance, durable wear-resistant parts, and low pollution.
