What is petroleum coke powder? Petroleum coke, is crude oil by distillation, after the separation of light and heavy quality oil, the heavy oil obtained and then converted into products by thermal cracking, petroleum coke can be used for graphite production, smelting and chemical industries depending on its quality. From the appearance, coke is irregularly shaped, black lumps or granules of different sizes, with a metallic luster, coke particles with porous structure, the main elemental composition of carbon.

Petroleum coke is an important chemical raw material, widely used in chemical, metallurgy, power plant and other industries. However, the petroleum coke collected directly cannot be used immediately, and needs to be processed by grinding machine and then applied in various industries. The petroleum coke mill is developed for petroleum coke material, which can well deal with the physical and chemical properties and mechanical properties of petroleum coke, so that petroleum coke can become a better raw material for the industry.

I. Petroleum Coke Mill

As the host equipment of grinding production line, it has three-dimensional structure, small footprint, strong completeness, independent and self-contained production system from lump material to finished powder, basically unmanned operation can be realized in the workshop, high efficiency, good quality and uniformity of the finished fine powder, high sorting precision, high sieve rate, and fineness can be adjusted according to the demand.

Second, process flow

Before pre-calcined raw coke, raw coke needs to be pre-crushed to less than 40mm, and then crushed again after coarse screening, some petroleum coke producers do not screen before coarse crushing, so that the smaller size of the required blocks and large petroleum coke directly into the crusher, the small pieces of raw coke have experienced another crushing, making the raw material finer; crushed material is sent to Raymond Mill for grinding, and the finished product passes through the powder selector and enters the cyclone collector. After crushing, the material is sent to Raymond Mill for grinding, and the finished products are collected by cyclone collector and pulse dust collector, and sent to the blower from the lower discharge port; pneumatic conveying system is installed at the discharge port of the blower to convey the finished products to the finished product warehouse, and the excess gas is filtered by the dust collector at the top of the silo; the whole system is configured with three pulse dust collectors, and air extraction ports are installed at all the dusty points to ensure that there is no leakage of dust in the whole system, and the site realizes the dust-free operation.

Third, what is the use of petroleum coke?

1, low sulfur, better cooked coke, such as needle coke, used in the manufacture of high-power graphite electrodes and some special carbon products, in the steel industry needle coke is an important material for the development of new technology of electric furnace steelmaking.

2、Medium sulfur, ordinary coke, a large number of used in aluminum refining.

3, high sulfur, ordinary raw coke, is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., as metal casting fuel.
