Study on coal blending to produce briquetting coke by using lean coal

This paper discuss the means of coal blending to produce briquetting coke by using lean coal which is picked in the eighth mine in Pingdingshan.At the beginning of experiment,after all the raw material having to be crushed and screened,come to carry out proximate analysis.Second,according to the coal blending principle start to map out the way of coal blending.Third,after the briquetting coal having to be prepared by cold-pressed machine,then make the briquetting coal which have been made to be briquetting coke through cold pressing,measure the compressive strength and reactivity of briquetting coke.Finally,through complete test analysis,The experiment results showed that 90% lean coal blended with an amount of 10% fat coal could produce excellent briquetting coke.
