Abstract
A mill for grinding flour and the like. Two flat grinding discs are mounted in opposed relation to one another. One disc is non-rotatably mounted with respect to the housing that supports it, while the other is rotated by a motor drive. The non-rotatable disc coaxially supports the shaft for the rotatable disc. The non-rotatable disc can be adjusted axially to vary the spacing between the grinding surfaces of the respective discs. Provision is also made for yieldable movement between the discs in response to the grinding load.
