English to Spanish Tech/Engineering Mechanics / Mech Engineering shell liners

Buenos días,

Espero que puedan ayudarme con la siguiente expresión al español: “shell liners”, relacionada con un molino rotatorio. Si pudieran también con “end liner”. Muchas gracias:

“End liners should be installed before shell liner installation. Bolt shell liners in the shell with ¼ in. to ½ in. space between adjacent liners and ½ in. to 1 n. space between liners and diaphragms, division heads, or end liners. The larger opening is for manganese steel castings due the inherent characteristics of manganese steel to flow.”
