The flour mill of this structure, because Burnisher apparatus arranges pinnacled plum blossom frame place, the height of Burnisher apparatus is higher, vibrations are large during use, operation stability is relatively poor; Weight is large, required drive is larger when rotating, and energy consumption is higher; Burnisher apparatus oiling maintenance, repair inconvenience.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of simple in structure, cost is low, can make flour mill reduce the easily bull ring of Multifunctional mill of energy consumption, stable, maintenance.

The purpose of this utility model is to realize by following technical scheme:

A kind of bull ring of Multifunctional mill, described bull ring are taper shape or annular.

The inner circle of described bull ring is provided with deep-slotted chip breaker.

A kind of Multifunctional mill of using above-mentioned bull ring, comprise central shaft, grinding roller, grinding roller frame and perching knife, bull ring is arranged in the base, central shaft is arranged on the central shaft bearing block by taper roll bearing, the central shaft bearing block is arranged on the bottom of base, central shaft is connected with power set, and the Center-to-Center axle of grinding roller frame is fixedly mounted with, and the equal five equilibrium of each grinding roller rotatably is arranged on the side of grinding roller frame.

Described grinding roller frame is circle or multi-corner star-shape.

Further, described grinding roller frame be triangle star ~ anistree star any.

Further, described grinding roller frame is triangle star or anistree star.

The side of described grinding roller frame is provided with the grinding roller groove.

Described grinding roller is cydariform or cylindrical, and its center is provided with the axis hole greater than the shaft of grinding roller external diameter.

During work, power set drive the central shaft rotation and make the rotation of grinding roller frame, the grinding roller that is arranged in the grinding roller groove also and then rotates around central shaft, grinding roller is subject to the effect of centrifugal force, impact to the bull ring inwall, be contained in relieving tool post below the grinding roller frame and perching knife also and then around the central shaft rotation, perching knife scoops up the abrasive material on the base, deliver between grinding roller, the bull ring, owing to be subject to the effect of frictional force between grinding roller and the abrasive material, grinding roller is around the shaft of grinding roller rotation, and abrasive material is rolled between grinding roller and bull ring becomes powdery.

This bull ring cost simple in structure is low, adopts the flour mill of this bull ring, and grinding roller is set directly in the grinding roller frame, saved baroque Burnisher apparatus in the former complete machine, thereby complete machine structure is simple, has saved the cost of complete machine; Also be applicable to simultaneously the transformation to existing flour mill, the cost of transformation is lower; In use saved the maintenance to Burnisher apparatus; Complete machine weight saving, the power that needs during work reduces, and has reduced energy consumption, has reduced production cost; The grinding roller frame is arranged in the base, has reduced the height of equipment, and vibration is little during work, operation stability is high.
