Crushing: Bones are conveyed through an auger from the receiving area to the crusher where bones are broken into pieces of about 10 cm in length. 2. Cooking: In the cooker, crushed bones are subject to saturated steam supplied from a fire tube boiler via the steam line to cook bones with fat and protein and kill any bacteria or pathogens.

Chalk, a type of limestone, makes up the white cliffs of Dover. Formed from the condensed layers of ancient coccoliths and foraminifera remains, the soft white mineral rates a 1 on Mohs Hardness Scale. Many of the world's largest chalk deposits began forming up to 65.5 million years ago during the Cretaceous Period.
