HAMMER WHEEL MECHANISM ABLE TO ADJUST GRINDING FORCE FOR ANNULAR ROLLER TYPE UPRIGHT MILL

Disclosed is a hammer wheel mechanism able to adjust the grinding force for an annular roller type upright mill wherein a swinging arm is provided on a star shaped mount via a swinging arm shaft one end of the swinging arm is provided with a hammer wheel via a hammer wheel shaft and a weight is provided on the swinging arm via an adjuster bolt. The present invention has the following technical effects: the weight is mounted on the other end of the hammer wheel swinging arm and is able to move transversely along the swinging arm; when the machinery is operating the weight generates an inert centrifugal force at the same time and according to the principle of the plane force system a balancing torque will exist at the fulcrum; adjusting the corresponding position of the weight or changing the weight of the weight itself can set or adjust the grinding force of the hammer wheel so as to achieve the best effects such that the machinery will effectively grind material increasing the quality of the product and improving the production efficiency of the machinery.
