An end runner mill uses a rotating mortar and revolving pestle to grind materials placed inside the mortar. As the mortar spins at high speeds, it causes the pestle to revolve as well, reducing the size of the materials through grinding. End runner mills are suitable for fine grinding applications. However, they are not well-suited for initial size reduction of unbroken or slightly broken drug materials.
