On wettability between formed coal powder and water, the measuring method has been developed by the present writer. In this report, the relation, between the wettability by above-mentioned method and the pelletizing property by Oil Agglomeration method, has been made clear, as in the following formula.
(D/C) 2 ∝ log B (1+sin θ)
where, θ: contact angle
B: the product between specific surface area of raw coal and pure coal percent of that
C: mean diameter of raw coal (on R-R-B size distribution co-ordinate system)
D: mean size of O. A. pellets
The apparatus of the above-mentioned O. A. method is shown in Fig. 1 and Fig. 2.
