"浆料悬浮液" can be translated as "slurry suspension" in English.
Here, "slurry" refers to a thick, fluid mixture of solid particles suspended in a liquid, often used in industrial processes, while "suspension" emphasizes the state where these particles are dispersed throughout the liquid without settling out quickly. Together, "slurry suspension" accurately conveys the meaning of a material containing solid particles in a liquid medium that remains in a dispersed state.
