Ball pulverizing pan

The ball rolls along the circular groove of the swung pan to pulverize the ingredients. The movement of the ball depends on the input speed, the amount of ingredients and their grain size.
This mechanism is numbered 1240 in the book “1800 Mechanical Movements, Devices and Appliances”, Gardner D. Hiscox, 1921.
