Abstract: Petroleum coke becomes industrial powder raw material after crushing grinding and classification. SBM LM vertical mill has high capacity and stable operation and can process petroleum coke into powder for carbon refractory and boiler fuel applications.
Petroleum coke is a solid carbonaceous material produced during petroleum refining. After calcination and grinding it becomes an important raw material for carbon products refractory materials industrial boiler fuel cement admixture and other fields. Petroleum coke is characterized by high fixed carbon high calorific value but also high hardness and abrasiveness. The grinding process places high requirements on equipment wear resistance stability and transmission system reliability. Improper equipment selection may lead to rapid wear output fluctuation and frequent maintenance.
To meet petroleum coke grinding requirements SBM has developed the LM vertical mill. Full product details are available at
SBM LM vertical mill. The LM vertical mill adopts the material bed grinding principle. Materials are crushed by grinding rollers on the grinding table. It has a compact structure and high processing capacity making it suitable for petroleum coke which has medium hardness and certain abrasiveness. The roller sleeves and table liners can be made of highly wear resistant materials to withstand long term grinding. The hydraulic system adjusts roller pressure according to material hardness keeping grinding efficiency and equipment load within a reasonable range.
The LM vertical mill also integrates drying grinding classification and conveying functions. For petroleum coke with certain moisture the hot air system can complete drying inside the mill reducing the investment in external drying equipment. Finished powder fineness can be adjusted through the classifier to meet different industry requirements for carbon raw material refractory material and boiler fuel. The system operates under negative pressure and works with dust removal equipment to reduce dust leakage and improve workshop environment.
In petroleum coke projects SBM engineers usually first evaluate the raw material properties such as fixed carbon volatile matter moisture ash content hardness and feed size. Then they determine host specification roller pressure air volume classifier speed and hot air source configuration. The process arrangement will be different for green coke and calcined coke. For coarser boiler fuel petroleum coke powder the system can adopt large air volume and coarse classification configuration to improve output.
The economics of petroleum coke grinding projects depend mainly on capacity power consumption wear part life and operating rate.

Conclusion: The LM vertical mill adopts the material bed grinding principle and is suitable for petroleum coke grinding. It features high capacity long wear part life and integrated drying grinding classification and conveying functions.
FAQ
Q1: Is the LM vertical mill suitable for green coke or calcined petroleum coke?
A1: It can be configured for both but calcined coke has higher hardness and abrasiveness so wear part material and hydraulic pressure need special attention.
Q2: What fineness can petroleum coke powder reach?
A2: It can be adjusted over a wide range according to application. Boiler fuel powder is usually coarser while carbon raw material powder may require finer and more uniform particle size distribution.
Q3: Is explosion protection required for petroleum coke grinding?
A3: Yes. Petroleum coke powder is combustible. Temperature monitoring explosion and pressure relief protection and dust removal measures should be considered based on fineness moisture and operating conditions.
