An Investigation of the Relationship Between Raw Coal Caking ...
Feb 3, 2022The relationship between the caking parameters and maceral properties of coal was obtained by testing and analysis. The results show that the formation of colloids in coal is mainly related to the vitrinite composition and the Audibert-Arnu dilatation and caking index are closely related to the average maximum vitrinite reflectance.

From different float and sink data of coal crushed to different sizes, the degree of liberation can be calculated. For coal, the degree of liberation can be expressed as per the equation (5.2.1). L= (Y (100-Z))/ ( (100-X)) (5.2.1) Where, Y = weight of free particles i.e. yield % of clean coal Z = ash % of clean coal X = ash % of raw coal
