The squeezed transportation pump is specialized equipment used for transporting fill in backfill mining. The transporting pump, combined with the self-flow transporting process which makes good use of the gravity of the filling slurry in vertical (or inclined) pipes as well as the yield stress of the slurry along the pipe wall, can transport the slurry to distant stopes when installed at an appropriate site in the pipeline. Compared with traditional concrete pumps, the squeezed transporting pump,which offers such characteristics as unique design conception, innovative and simple structure and advanced technology, provides an effective solution to the difficulty with long distance transporting of fill in mines.
