  • grinding characteristics of wheat in industrial mills

    grinding of cereal seeds is due to the mechanical action of several forces: compression, shearing, crushing, cutting, friction and collision, to which seeds are subjected, depending on the design if the mill used for grinding (roller mill, hammer mill, stones mill or ball mill). by applying these forces, when the mechanical resistance of the particles is exceeded, their division happens in a
