... Abstract Research on free settling of coarse mineral particles is very important and fundamental to design of the hydraulic lifting pipe system. Based on mechanical property of coarse particles in fluid, a formula for calculating the settling rate of the coarse mineral particles dropped...

... to the square of fluid velocity and pipe abrasion is in proportion to the cube of fluid velocity, respectively. Therefore, it is desired to determine a critical velocity for a vertical hydraulic lifting system. coarse particle single particle coefficient coal particle two-phase flow experimental...
