- Note
- "A bone crusher is a device regularly used for crushing animal bones. Bones obtained during slaughter are cleaned, boiled in water and dried for several months. After that, they are suitable for crushing with the special machine into a relatively dry gritty powder which is used as fertilizer.
The machine, shown in the picture, is powered by a water wheel. It contains eight S-shaped pairs of cams that raise the crushers alternately and let them fall into material to be crushed. The simple transmission increases the rotation speed of the crusher wheel to 21 rpm from the water wheel speed of about 7 rpm." - (en.wikipedia.org 22.12.2021)
