Introduction of calcined petroleum coke and pulverizing equipment
Release time: number:

Calcined Petroleum Coke: In order to adapt petroleum coke (green coke) to the requirements when graphite electrodes for steelmaking or anode pastes (melt electrodes) for aluminum and magnesium production are used, green coke must be calcined . The calcination temperature is generally around 1300 ° C, the purpose is to remove the volatiles of petroleum coke as much as possible. In this way, the hydrogen content of petroleum coke re-products can be reduced, and the graphitization degree of petroleum coke can be improved, thereby improving the high temperature strength and heat resistance of graphite electrodes, and improving the electrical conductivity of graphite electrodes. Calcined coke is mainly used for the production of graphite electrodes, carbon paste products, corundum, food-grade phosphorus industry, metallurgical industry, and calcium carbide, among which graphite electrodes are the most widely used.

There are many kinds of mills that can be used for the calcined petroleum coke powder. Raymond mill, vertical mill, and ball mill can be used. The high-pressure mill of Jianye Metallurgy is a representative product among Raymond products. There are many cases of application in the carbon industry. The complete system of the high-pressure mill is composed of: feeder, crusher, hoist, silo, electromagnetic feeder, mill main machine (including analysis machine, grinding chamber, soft connection parts, analysis machine), fan auxiliary machine (Including pipelines, aggregates, discharge devices), pulse dust collectors, etc. The main parts of the grinding chamber are the plum frame assembly, the grinding roller and the grinding ring.

The advantages of high pressure mills for petroleum coke grinding are as follows:

1. The grinding roller bearing room adopts a multi-stage labyrinth overlapping and cross-sealing structure, and is equipped with a double-layer sealed protective cover; ensuring that no dust enters the grinding room. 3 sets of positive and negative nut positioning, plus screw locking device, bearing positioning will never change. The three-pronged approach ensures continuous operation of the equipment, and the roller chamber bearings do not need to be replaced for 5 years. It completely solves the problem of poor sealing of the general bearing part of the ordinary mill, which is easy to damage the bearing due to ash. The lock plate is easy to fall off and cause the bearing to be displaced. The labor cost is reduced, unmanned operation is realized, and the production capacity is completely released.

2. The grinding system is equipped with a linkage balanced pressure device, which automatically boosts the balance afterburner; the main engine runs more smoothly. After the grinding rollers and grinding rings are normally worn, the spring tension can be adjusted to compensate for the problems such as insufficient pressure and reduced output after the grinding rollers and grinding rings are worn. Ensure the mill output is balanced and increase the output of ordinary mill by 30%.

3. The connection between the main body and the analysis machine adopts high-elastic rubber material software connection, which completely eliminates negative energy such as resonance and shear force of the equipment, and greatly improves the stability.

4. The equipment adopts multi-stage cyclone separation, negative pressure circulation, pulse filtering, combined supporting dust removal system. The equipment has no dust emission, and the dust removal effect is good, meeting national environmental protection standards.

5. The high-pressure mill is a suspension roller mill, which is helpful for the production of needle-shaped petroleum coke particles.

The carbon industry is closely related to the smelting industry and the foundry industry. The use of high-pressure pulverizers can improve the grinding efficiency and effect of petroleum coke and is a good choice for energy saving and emission reduction!
