Background
WikiWaste has used the website Cement Plants and Kilns in Britain and Ireland[2] extensively for the histoical reference material for each individual cement kiln page.
Ketton started manufacturing clinker in 1929 and up to 2015 had produced 56 million tonnes of clinker through 8 rotary kilns over this period.
The process at the site is similar to that at Cookstown - a 'semi-dry process' from kiln supplier Polysius (part of the ThyssenKrupp group).
