the flour milling machine------- FDMW type double units wheat scourer Characteristics (1).reasonably chooses the dense alignment and screw angle of the hit wooden board, make a good effect of the scourer and low crash rate (2).increased the diameter of screen drum suitable that overcome the phenomenon of plugging machine. (3).improved bearing lubricate and airproof structure, reduce the dynamical consumption and noise. (4). hit wooden boards of rotor through heat treatment that can extend the service life. (5).the running of rotor will more stable after the dynamic test and compensates. (6).toothed plate of screen drum changed from alloy chilling cast iron of anti-friction to the common ash cast iron, this can enhance the anti-friction degree and service life obviously.
