(Bolton and Gui, 1993) investigated this correlation by conducting centrifuge tests at target g-level 70 in Fontainbleau sand. This well-known uniform, silica sand with rounded particles has a d 50 equal to 0.181 mm and a coefficient of uniformity C u =1.69. The limiting void ratios of the sand are e min = 0.55 and e max = 0.92.

T Series Dewatering Decanter Centrifuge Features. The beach angle of the T Series dewatering centrifuge is 8.5 Degree, which makes the decanter centrifuge cone section longer, that is, the drying and dewatering area of the centrifuge is longer, which is conductive to the dewatering performance of T Series decanter centrifuge, and much …
