Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crushing raw material selection and supply device used in a centrifugal crusher for crushing raw materials such as minerals.

[0002]

[Prior art]

 As a device for crushing raw materials such as minerals, a centrifugal crusher a (Japanese Patent Application No. 63-59329) as shown in FIG. 3 has been conventionally known. This crusher a sorts the crushed raw material b that has been fed in by means of a bone-shaped sorting supply device c of a rotatable umbrella, and the crushed raw material having a relatively small diameter is placed in a rotor d and has a relatively large diameter. The crushing raw material can be supplied between the outer peripheral surface of the rotor d and the collision portion e such as a dead bed or a steel anvil. Then, the crushing raw material having a relatively small diameter discharged from the rotor d rotating at a high speed and the crushing raw material having a relatively large diameter supplied between the outer peripheral surface of the rotor d and the collision portion e are caused to collide with each other. Further, it is crushed by colliding with the collision part e.

[0003]

[Problems to be solved by the device]

 The above conventional technique has the following problems. The conventional sorting / supplying device c is a top plate f for forming a dead bed for buffering the impact of falling crushed raw materials, and a rod-like member protruding radially from the side surface of the top plate f at a predetermined interval. It is composed of the component g. Here, since the constituent member g group is provided with the tip portion inclined downward at a constant angle, the constituent member g group is arranged on substantially the same plane. Therefore, when the crushing raw material is charged by rotating the sorting and supplying device c, the crushing raw material having a relatively small diameter, which should pass through the falling space h, collides with the rotating component member g and the rotor d and the collision portion e. It will be played in the meantime. Therefore, the required supply amount of the crushing raw material into the rotor d cannot be obtained, and the crushing capacity is lowered.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and by reliably selecting the crushed raw material according to the particle size and appropriately controlling the supply amount inside and outside the rotor, It is an object of the present invention to provide a crushing raw material selection and supply device used in a centrifugal crusher capable of improving crushing efficiency. That is, the crushing chamber formed in the crusher housing, the collision member provided in the peripheral portion of the crushing chamber, and the crushing raw material colliding from the peripheral opening at the center of the crushing chamber and rotating horizontally. A rotor for discharging toward the member, a first supply passage for supplying the crushing raw material into the rotor, and a second supply passage for supplying the crushing raw material between the rotor peripheral surface and the collision member. In a centrifugal crusher, a sorting and feeding device that sorts and feeds the crushing raw material into the first and second feeding passages, in which rod-shaped or strip-shaped constituent members are radially arranged and can be horizontally rotated. The crushing raw material used in the centrifugal crusher is characterized by a simple integrated structure, and a part of the constituent members is placed below every other constituent member or every other constituent member. It is a supply device.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. <a> Top panel The sorting and feeding apparatus 1 of the present invention is shown in FIGS. The sorting and supplying apparatus 1 is composed of a top board 11 and upper and lower parts constituting members 12 and 13. The top board 11 is a disk-shaped body such as a circle formed of a rigid member such as steel, and a low wall body is erected on the peripheral edge thereof to form a saucer shape. On the top plate 11, a crushing raw material supplied by dropping from the upper part is deposited to form a dead bed, and the shock upon dropping is buffered.

<B> Upper Component Member The upper component member 12 uses a rod-shaped or strip-shaped steel material or the like. One end of the upper constituent member 12 is joined to the outer peripheral surface of the wall of the top board 11 by welding or the like, and the other end is tilted slightly downward so that the top board 11 has a predetermined interval. Install radially.

<C> Lower Component Member The lower component member 13 is a member similar to the upper component member 12, which is mounted radially between the upper component members 12 with a predetermined space between them. However, the lower constituent member 13 is attached such that its tip portion is located lower than the upper constituent member 12 and the inclination angle is large. For example, the inclination angle of the upper component 12 is about 10 degrees, and the inclination angle of the lower component 13 is about 20 degrees. As described above, the upper and lower constituent members 12 and 13 are radially mounted around the top board 11 to form the sorting and supplying apparatus 1. The sorting and feeding device 1 is configured to be rotatable in the horizontal direction by a rotation driving device. For example, as the rotary drive device, as shown in FIG. 2, a rotary motor 2 or the like that rotatably supports the top board 11 is used, but other known devices are also possible. By adjusting the pitch between the upper and lower constituent members 12 and 13, it is possible to arbitrarily select the particle size of the crushing raw material to be selected and dropped. Further, although FIG. 1 shows the case where the upper and lower part constituting members 12 and 13 are arranged every other line, there may be a case where any one of the upper and lower part constituting members 12 and 13 is arranged every plural lines. Further, although FIGS. 1 and 2 show the case where the upper and lower component members 12 and 13 are tilted downward toward the tip, the case where they are tilted horizontally or upward toward the tip is also conceivable.

<D> Grooved Drop Space Since the lower component member 13 is located below the upper component member 12, the crushing raw material drop space between the upper and lower component members 12, 13 is not a flat surface as in the conventional case. , A groove-shaped falling space 14 having a depth. Therefore, as shown in FIG. 2, the crushing raw material dropped and supplied onto the rotating upper and lower constituent members 12 and 13 can be captured by the groove-shaped dropping space 14. Therefore, the crushing raw material 3 having a relatively small diameter is dropped from the groove-shaped dropping space 14 and is supplied into the rotor while sliding on the upper and lower constituent members 12 and 13 in the tip direction. On the other hand, the crushing raw material 4 having a relatively large diameter slides on the upper and lower constituent members 12 and 13 and is discharged from the front end portion, and can be supplied between the rotor and a collision member such as a dead bed. .

[0009]

[Effect of the present invention]

 Since the present invention is configured as described above, the following effects can be obtained. <a> By configuring the sorting and supplying device with the upper and lower constituent members, the space for dropping the crushing raw material between the constituent members is formed in a groove shape having a depth instead of a flat surface as in the conventional case. be able to. Therefore, the crushing raw material that is dropped and supplied onto the rotating component member can be captured by this groove-shaped drop space, and can be reliably sorted and supplied while sliding on the component member in the tip direction. Therefore, an appropriate amount of crushing raw material can be supplied to the inside and outside of the rotor, and crushing efficiency can be improved.

<B> Since the crushing raw material can be supplied at the set amount, it is easy to adjust the crushing raw material supply amount to the inside and outside of the rotor, and the crushing particle size can be selected easily and reliably. It
