2019-12-14 · The rate of shear, or velocity of flow, of the bulk solid material stream in contact with the transfer chute wall lining for the case presented is in the range of 4.0–12.0 m/s. Another consideration is that the chute wall lining friction reduces with service life, through polishing or constant abrasion by the flowing stream.
