Answer 2

30

The ratio of the flighted length to its outer diameter is stated. The ratio is calculated by dividing the flighted length by the nominal diameter.

Use LD 30 for the best mixing results.

Disadvantages --

1. The material is heated for a longer time,
2. it takes longer to travel through the machine, and
3. more material is wasted during the transition.
