For the production of petroleum coke milling, SBM heavy machine has rich experience in program production. At the same time, the principle of producing ultra-fine vertical roller mill for petroleum coke is scientific, cost-effective, high efficiency of powder selection, large output, energy consumption. Low is the best choice for efficient processing of petroleum coke. For a series of questions, what is the petroleum coke? How to formulate the petroleum coke ultra-fine vertical mill grinding machine and what kind of working principle: 1. What is petroleum coke? Petroleum coke is a type of coke produced by delayed coking of residual oil. The essence is a partially graphitized carbon form. The color is black and porous, and it is in the form of stacked particles and cannot be melted. The elemental composition is mainly carbon, with little or no hydrogen, nitrogen, sulfur, oxygen and certain metallic elements, sometimes with moisture. The petroleum coke produced from petroleum coke sites is called coke, contains some volatiles of uncarbonized hydrocarbon compounds, and can be used as fuel grade petroleum coke if it is to be used for anode or steelmaking of aluminum smelting. The electrode needs to be calcined at a high temperature to complete the carbonization and reduce the volatile content to at least (referred to as calcined coke or cooked coke). Petroleum coke can be used in the industries of graphite, smelting and chemical industry according to its quality. With the continuous improvement of processing technology, the application market of petroleum coke will continue to expand. SBM heavy machine will also pay attention to the development prospect of petroleum coke market. The product structure of the mill further meets the processing needs of petroleum coke. 2. Principle and performance of ultra-fine vertical mill Ultra-fine vertical roller mill is a high-quality equipment dedicated to the deep processing of petroleum coke. It has comprehensive mechanical pulverizing properties such as rolling, grinding and impact. It can process 325-2500 mesh high-quality powder to achieve high-efficiency milling, complete system. It is mainly composed of main engine, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, etc. The forced turbine grading system is the new dust collection system used by the equipment, and the dust collection efficiency is as high as 99%. The workshop is very clean and tidy, and it can realize a dust-free processing workshop. It is an energy-saving and environment-friendly milling equipment for local petroleum coke milling equipment. The material is crushed into less than 10mm by the jaw crusher, and is lifted to the storage hopper by the bucket elevator, and then fed into the main cavity by the feeder for grinding. The material is pulverized and ground in the main cavity. The powder falls to the bottom plate due to gravity, and is blown to the classifier above the main machine under the action of the airflow of the blower for screening. If the fineness is too thick, it still falls into the main machine for re-grinding, and the fineness meets the specifications and flows with the wind. The pulse dust collector is collected after being discharged through the discharge valve, and the purified airflow flows into the blower through the residual air pipe above the pulse dust collector. The air path is circulated, except for the positive pressure of the blower to the grinding chamber, and the other pipelines The airflow flows under negative pressure, no dust is leaked out, and the workshop basically guarantees dust-free operation.
