State whether the following is true or false.
Screw conveyors are well suited to abrasive materials such as quartz.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: B

The flight rubs continuously against the trough and the material, so an abrasive charge wears both quickly. Belt conveyors, which carry rather than drag, are preferred where the material is hard and the distance is long.
