Frequently asked questions

What is line efficiency?
The share of time the line really produces without stops for changeovers, cleaning and breakdowns; usually 75–90 %.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
