work safety in grinding limestone

Hydrated lime reacts with carbon dioxide to create calcium carbonate. This reaction (desired for mortar) rules out grinding of hydrated lime on a mill as it would take place inside the mill and lead to clogging. Due to this a necessary grinding step needs to be situated before the hydration step of lime. Roller Mills, Universal Mills and Gap Mills
