2. How does a hammer mill bone grinder work?

   • Answer: A hammer mill uses a rotating hammer to shatter the bone. Bones are fed into a chamber where hammers, attached to a rotor, strike the bones at high speed, breaking them into smaller pieces. The size reduction is achieved through impact and shearing.

3. What is the capacity of a typical bone grinder?

   • Answer: The capacity varies significantly depending on the grinder's size and model. Small grinders might process a few kilograms per hour, while industrial-sized grinders can handle hundreds of kilograms per hour.
