Abstract

A method of transferring a slurry is provided. The method involves transferring a slurry containing particles and a liquid using a transfer pump equipped with a ball type check valve. The transfer pump is operated under the condition satisfying the following formula: 7.8×10³5. In the formula, P=W(ρ₁/(ρ_b−μ₁))^0.5/(C·d(d+R)R^0.5). W represents the particle flow rate (kg/hr) in the slurry passing through the ball type check valve, C represents the particle concentration (kg/m3) in the slurry, d represents the maximum particle diameter (m) of the particles in the slurry, R represents the ball diameter (m) of the check valve, ρ1 represents the density (kg/m3) of the liquid, and pb represents the density (kg/m³) of the ball of the check valve.
