Petroleum coke is a product obtained by thermal cracking of heavy oil, which is separated from crude oil through distillation. It has an irregular shape and consists primarily of carbon. Based on its form, it can be classified into four types: needle coke, pellet coke, sponge coke, and powdered coke. As a vital industrial raw material, petroleum coke, after being ground into powder, is widely used in graphite manufacturing, smelting, chemical processing, and fuel substitution. The precision and efficiency of its processing directly determine the product’s added value and the enterprise’s market competitiveness, and a high-quality petroleum coke grinding mill is the core equipment for achieving efficient deep processing of petroleum coke. With the global industrial upgrade, the demand for petroleum coke powder has been rising year by year. Selecting a scientific petroleum coke grinding process and high-performance petroleum coke grinding equipment has become a core requirement for enterprises engaged in the deep processing of petroleum coke, as it not only ensures the quality of petroleum coke powder applications but also enhances production efficiency.


Petroleum coke grinding must follow a scientific processing procedure to ensure stable product quality and meet production capacity targets. A complete petroleum coke grinding production line is primarily divided into four stages: First is the crushing stage, where large chunks of petroleum coke are crushed by a crusher to 15–50 mm to meet the feed requirements of the grinding mill; Second is the grinding stage, where the crushed petroleum coke is transported by an elevator to a silo and then fed uniformly and in measured quantities into the grinding chamber of the petroleum coke grinding equipment via a vibrating feeder. Depending on the required fineness of the final product, LM vertical mills or MTW European-style mills can be selected for fine powder processing, while LUM ultra-fine vertical mills are suitable for ultra-fine powder processing, catering to various petroleum coke deep-processing needs; Next is the classification stage, where the ground petroleum coke powder is classified by a classifier; non-conforming coarse powder is returned to the main unit for re-grinding; Finally, the powder collection stage: qualified powder enters the dust collector via an airflow for separation and collection, then is conveyed to the finished product silo via a conveying system, completing the entire petroleum coke powder production process.
When selecting petroleum coke grinding equipment, special attention must be paid to the equipment’s wear resistance, explosion-proof capabilities, and energy efficiency. Petroleum coke has a high hardness (Mohs hardness 2.5–3.5) and contains a certain amount of volatile matter; temperature must be controlled during the grinding process to prevent spontaneous combustion. Therefore, the equipment must have excellent sealing and temperature control capabilities. The MTW European-style grinding mill and LM vertical grinding mill, developed by Shanghai Shibang, are specifically optimized for the characteristics of petroleum coke. They feature high-chromium alloy wear-resistant components, a fanless sealing structure, and a precise airflow classification system, which effectively prevents dust leakage and reduces the risk of combustion and explosion. Meanwhile, energy consumption is reduced by 30%-40% compared to traditional ball mills, and the finished product fineness is flexibly adjustable within the range of 20-3250 mesh, with a 325-mesh yield of ≥95%, meeting the application needs of various industries.


Petroleum coke powder has a wide range of applications. In the carbon industry, it can be used to produce graphite electrodes and prebaked anodes, suitable for scenarios such as aluminum electrolysis and steel smelting; in the chemical industry, it can be used to produce silicon carbide and activated carbon, enhancing product purity and performance; in the fuel sector, it can replace heavy oil as fuel for industrial furnaces and kilns, achieving energy savings and reduced consumption. Different application areas have varying requirements for the fineness and purity of petroleum coke powder. For example, the electrolytic aluminum industry requires calcined coke powder of approximately 200 mesh, while the production of high-end anode materials requires ultra-fine powder of 325 mesh or higher. Therefore, grinding solutions must be customized according to actual needs.
Currently, the petroleum coke deep processing industry faces challenges such as high energy consumption, dust pollution, and inconsistent product quality.
