  • Light Weight Insulating Bricks from Coal and Clay

    coal size. Cold Crushing Strength Fig. 4 shows the effect of coal addition on cold crushing strength (CCS) of insulating bricks. It reveals that CCS decreases with increase of coal addition. With the increases of coal addition the amount of porosity and load bearing area decreases. As a result CCS decreases with the increase coal addition.

  • Crushing properties of coal | SpringerLink

    Abstract. Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient.There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.
