The slurry pump belongs to a kind of centrifugal pump in terms of physical principles. Conceptually, it refers to a machine that increases the energy of the solid and liquid mixed medium through centrifugal force (the rotation of the pump's impeller). A device for the kinetic and potential energy of a medium. It is widely used in mining, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles, including mining slurry transportation, thermal power plant hydraulic de-ashing, coal washing plant coal slurry and heavy media transportation, dredging, river dredging and so on.
