  • Three roll mill
    Patent number: 8727253
    Abstract: A three roll mill having a feed roll, a center roll, and an apron roll with that are driven so that their cylindrical surfaces move in the same direction but different speeds in each nip. One end of each roll is engaged by a drive shaft at a first side of the mill, whereas the other end of each roll rotates freely at a second side of the mill. Each roll can be removed individually and without tools by moving the roll away from the first side against a spring force in the second side. This disengages the roll from its drive shaft, whereupon it can be lifted out of the mill.
