Kinds of petroleum cokes uses:
Petroleum coke (often abbreviated Pet coke or petcoke) is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Other coke has traditionally been derived from coal.
Marketable coke is coke that is relatively pure carbon and can be sold for use as fuel, or for the manufacture of dry cells, electrodes, etc. 
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either FCC decant oil or coal tar pitch. 
Catalyst coke is coke that has deposited on the catalysts used in oil refining, such as those in a fluid catalytic cracker. This coke is impure and is only used for fuel.
Calcined petroleum coke is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminium, steel and titanium smelting industry.

Application of Petroleum coke high pressure grinding machine:
CLIRIK Petroleum coke high pressure grinding machine is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

Working Features of Petroleum coke high pressure grinding machine:
Petroleum coke high pressure grinding machine has the similar working principle as general Raymond mill, but its grinding device is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller, which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of High pressure suspension grinding equipment given an identical condition and its capacity increase 20% to 30%; when the grinding roller and grinding ring, stable capacity and fineness are guaranteed.

Working Principle of Petroleum coke high pressure grinding machine:
Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
