The advantages of MTW European type trapezium mill to process petroluem coke
As the main raw material prepared by synthesis processing, petroleum coke can be as a fuel alternative to oil. Petroleum coke is a non-polar hydrocarbons with porous structure, belong to hydrophobic substances. Petroleum coke is the end product of petroleum family.It has the features of both the physical properties of the oil and oil thermal performance. After the first level of crushing, drying, grinding process,petroleum coke can be made of a certain strength specifications petroleum coke powder. Through the transport system of quantitative continuous, uniform, stable combustion injected into the furnace, the heat generated by the high-effective material for the kiln melt, we can produce a variety of products to meet the quality requirements.
As a solid fuel, after good atomization,petroleum coke forms high turbulence into the kiln at a high temperature state, by radiation and convection is rapidly heated to the ignition point of the combustion heat. Petroleum coke powder heat up to 8,500 to 9,000 calories,its burning point is of 500 ℃ ~ 700, the combustion temperature up to 1500 ℃ ~ 1800 ℃ with no volatilization during combustion and post-combustion residue composition is essentially zero. It is the ideal city fuel with energy saving, environmental protection and economic feature.
In the field of petroleum coke processing, Liming Heavy Industry's European type mill has following new advantages:
Firstly, for the characteristics of light proportion,petroleum coke is not easy to form a powder abrasive layer, Liming Heavy Industry optimized and blade grinding device host structure, while taking an advanced turbine classifier cage.The unique design and a constant flow gas-solid concentration control technology make the finished petroleum coke powder out of uniform particle size, narrow distribution, no large particles and to ensure stable operation of the system for a long time and improve productivity.
Secondly, Liming Heavy Industry combine its experience in industries such as coal, petroleum coke used as fuel with a certain degree of risk, so the device is provided with a venting device in order to improve the safety of the device.
Thirdly, the machine is fully enclosed negative pressure operation. The production environment is clean with no dust pollution. Dust emission is less than 30mg/m3 which is fully meet the national environmental requirements.
Fourthly, the United States' latest off-line cleaning filter technology to effectively guarantee the cleaning effect. Bag using hydrophobic oleophobic coating bag (for strong adhesion of the powder such as: petroleum coke, etc.) and increases dust filtration area, powder in a small bag on the adhesion to ensure stable operation of the system for a long time.
