The designed annual processing capacity of Gucheng Coal Preparation Plant of Shandong energy linkuang group is 1.8 million tons The original coarse slime classification process of coal preparation plant has some problems, such as low classification efficiency, coarse slime water under coarse slime screen and ash content of coarse clean coal slime on screen exceeding the standard; after adopting Haiwang "1 + 1" coarse slime fine classification process and technical innovation of key equipment, the problem has been solved Over standard ash content of coarse coal slime and "roughening" of slime water system It has created good economic benefits.
technical innovation plan
After the research of "Haiwang + 1" coarse slime classification technology, Haiwang's "coarse slime classification technology" was fully selected Technical reform of jig clean coal screen water To replace the original multiple sets of electromagnetic vibration screen and high frequency screen recovery process.
Effect of technical transformation
Process effect evaluation of laminated vibrating screen
The achievement of "development and application of coarse slime fine classification and ash reduction laminated fine screen" has been appraised by China Coal Industry Association and achieved the International advanced level , China's coal industry Science and Technology Award second award 。
