The crushing member 24 has two parallel plates 241 and 242 on the upper and lower sides. The plurality of blade plates 243 are spaced apart in the circumferential direction in a state in which they are inclined at a predetermined angle to the rotation direction side of the crushing member 24 with respect to the radial direction on the outer circumferential edge portions between the two circular disks 241, Respectively. A circular supply opening B is formed at the central portion of the upper disc 241 at the center side of each blade 243 with a center of the rotary shaft C of the pulverizing member 24 as a center.

The crushing member 24 is disposed in the casing 21 such that the supply opening B is concentric with the discharge opening A. [

Here, each of the vane plates 243 may have a curved shape or any other shape in addition to a linear shape in cross section parallel to the both circular plates 241 and 242.

The supply pipe 25 extends from the discharge opening A vertically through the discharge cylinder 22 so that the center axis of the cylinder 25 is positioned on the rotation axis C of the crushing member 24 Is drawn into the casing (21) and is arranged by inserting a tip end from the supply opening (B) into the inside of the crushing member (24).

The discharge opening A of the casing 21, the supply opening B of the crushing member 24 and the supply pipe 25 are formed so as to be capable of moving in the direction of the axis of rotation of the crushing member 24 C as a center.

In the pulverizer according to the embodiment of the present invention, the raw material R such as grain is rotated at a high speed around the rotation axis C in the vertical direction by the motor 31 from the tip opening of the supply pipe 25 And is supplied to the inside of the pulverizing member 24 to be driven.

The raw material R supplied to the inside of the crushing member 24 moves to the outer circumferential side by the centrifugal force due to the rotation of the crushing member 24 so that a strong impact is generated by the respective blades 243 And is sent to the side of the outer periphery of the crushing member 24 while being crushed.

The crushed material sent out to the side of the outer periphery of the crushing member 24 rises along the inner circumferential surface of the casing 21 due to the blowing action of the respective vanes 243, And the upper surface of the upper disc 241 of the crushing member 24 is moved toward the center side of the casing 21 so that the suction force of the suction fan causes the gap And is discharged through the cylinder 22 and the discharge pipe 23.

[

The diameter d2 of the supply opening B of the crushing member 24 is set to be smaller than the diameter d2 of the supply opening B of the crushing member 24 when the annular projection wall 211 is formed in a suspended manner on the upper surface of the casing 21. [ Shaped protruding wall 211 formed on the upper surface of the casing 21 is larger than the diameter of the annular protruding wall 211 formed between the protruding wall 211 and the inner peripheral surface of the casing 21 A part of the coarse ground product is refluxed into the inside of the grinding member 24 and is further ground in the grinding member 24.

Therefore, in the case where an annular protruding wall 211 is formed on the lower surface of the casing 21 so as to narrow the gap between the upper surface of the upper disc 241 of the crushing member 24 and the upper surface of the upper disc 241, If the diameter d2 of the supply opening B of the crusher 24 is larger than the diameter of the annular protruding wall 211 formed in the upper surface of the casing 21, Water can be obtained more effectively.

Further, in the embodiment of the present invention, each technique related to the modified example of the crushing section 2 may be used alone or in any combination.

In the embodiment of the present invention, a flange-like guide portion for guiding the raw material R supplied to the inside of the crushing member 24 in the outer circumferential direction may be formed in the lower portion of the supply pipe 25.

Since the raw material R can be effectively transferred between the blade plates 243 of the crushing member 24 by forming the flange-shaped guide portion at the lower portion of the supply pipe 25, It is possible to crush efficiently.

In the embodiment of the present invention, by forming the guide portion on the flange at the lower portion of the supply pipe 25, it is possible to prevent the raw material R from being squeezed, It can be reliably prevented from being discharged to the outside.

It is needless to say that the present invention is not limited to the above-described embodiment, and that the constitution can be appropriately changed without departing from the scope of the invention.
