State whether the following is true or false.
A single cement mill can produce several different cement types.

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

Answer: A

Correct answer: True

One mill serves several products by changing the feed proportions and the target fineness - ordinary Portland, a blended cement with slag or fly ash, a limestone cement, a finer rapid-hardening grade. The constraints are the cleanout between campaigns and enough silo capacity to keep the products apart.
