INDUSTRY BACKGROUND
Petroleum coke is a product of crude oil which is separated by distillation from light and heavy oils and then transformed into heavy oils by thermal cracking. From the appearance, coke is irregular in shape, black lumps (or particles) of different sizes, with metallic luster, coke particles have porous structure, and the main element composition is carbon.
After processing, petroleum coke can be used in graphite production, smelting, and chemical industries, depending on its quality. With the recovery of steel and electrolytic aluminium industry, the demand for carbon products made from petroleum coke has increased, and the market profit is considerable.
APPLICATIONS OF PETROLEUM COKE
Coke: Used as Fuel in Glass & Ceramics Factories
Production Fineness: 180mesh D90
Applicable Material: coke.Need high calorific value and good abrasiveness. It is mainly used in high-energy-consuming industries such as glass, cement, and power generation as an alternative fuel to significantly reduce production costs.
Calcined Coke: Used to Make Graphite Electrode
Production Fineness: 200mesh ＞D70
Applicable Material: calcined coke with low sulphur and high quality, such as needle coke, is mainly used to manufacture ultra-high power graphite electrodes and some special carbon products. In the steel-making industry, needle coke is an important material for developing new technology of electric furnace steelmaking.
Zenith has developed and produced new products such as vertical roller mill, European trapezium mill and ultrafine powder grinding mill, and offers integrated grinding solutions for high-quality petroleum coke powder that meets the needs of different industries.
THE PROCESS OF GRINDING SYSTEM
Grinding
stage
Material of suitable size is fed into the main machine for grinding, and the fine powder after grinding is sent to the analyzer for grading under the action of the air flow of the fan, so that the fine powder with qualified fineness can enter the collecting stage.
Collecting
Stage
The dust gas enters the cyclone collector through the outlet pipe. Under the action of centrifugal force, most of the finished fine powder is separated. Redundant gas is discharged and sent to pulse dust collector. Then it becomes clean gas. Fine powder collected by cloth bags is transported to the conveying stage through screw conveyor.
Conveying
Stage
The finished powder collected by dust collector and cyclone collector is sent by screw conveyor to the next process or into finished product tank.
