Description

CRUSHER FOR NOTHING PARTIAL WEARING OUT OF ORE DEALING FACILITIES}

In the present invention, the uneven wear of the improved raw material processing equipment is prevented from generating uneven wear of the crusher which is crushed with 8 to 30 mm of grain ore required in the blast furnace and 8 mm or less of lower dead sand required for sintering. It is about a crusher that is missing.

Crusher is divided into a crusher (equipment for crushing to 50 ~ 250mm particle size) and crusher (particle size 8 ~ 30mm), as shown in Figure 1, the spider cap (SPIDER CAP from the top around the main shaft 70) 20, a mantle 60, a mantleliner 50, and a CON-CAVE LINER 40; Under the main shaft 70, there is a piston 150 for hydraulically operating the mantle 60 up and down, and the main shaft 70 is assembled in the center thereof to allow rotational movement. 80 and the accentlip bushing 90 are combined.

Thus, the power of the drive motor transmitted to the pulley 130 rotates the bevel gear 110 in the clockwise direction through the pinion gear 120 and the accent 80 is rotated while forming an eccentric.

According to the eccentric rotation of the accent 80, the crushing portion 45, which is a space between the mantleliner 50 and the concave-brainer 40 located outside thereof, is widened and narrowed. The stored iron ore is introduced into the shredding part 45 to be shredded in the shredding part 45.

However, during the crushing operation, the iron ore charged from the hopper 190 is scattered evenly in the crushing part 45 and is not uniformly introduced therein so that the concentrated cap is concentrated in one direction so that the spider cap 20 is in intensive contact with the iron ore and Concay brewer 40 causes extreme wear and tear early on, shortening the life of the facility, thereby causing a problem that the crushing efficiency is also sharply lowered.

In addition, if the wear wear is severe, the equipment must be stopped and the worn parts must be replaced. Accordingly, the downtime of the equipment is long, resulting in a decrease in productivity.

The present invention was created in view of the above-described problems of the prior art, and solves this problem, by concentrating in one direction by removing iron ore supplied from the hopper to remove the segregation phenomenon of the spider cap and corn cabrain It is an object of the present invention to provide a crush-free crusher of the raw material processing equipment to prevent the unevenness, thereby maximizing the productivity.

45: crushing part, 50: mantle liner,

60: mantle, 106: universal joint,

110: working cylinder, 118: rotating plate.

An object of the present invention described above is fixed and supported by a universal joint fixed to the upper end surface of the main shaft of the crusher for crushing the raw ore, and the spider cap installed on the upper end of the main shaft so as to enable smooth rotation by a bearing It is achieved by including a working cylinder which is supported and fixed through the bracket, and a rotating plate which is fixed to the upper end of the working cylinder and the upper surface of the protrusions formed with a plurality of protrusions at regular intervals along the circumferential direction.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail on the basis of the accompanying drawings.

Figure 2 is an enlarged perspective view of the main portion of the crushing machine without a single wear of the raw material processing equipment according to the present invention, Figure 3 is an internal structure of the crusher without a single wear of the raw material processing equipment according to the present invention.

According to Figures 2 and 3, the present invention is provided with an uneven wear prevention member 100 on the upper surface of the main shaft (70).

The anti-wear wear member 100 includes a universal joint 106 fixed to the main shaft 70, an operation cylinder 110 coupled to the universal joint 106, and a rotating plate fixed to an upper end of the operation cylinder 110. And 118.

The universal joint 106 is connected to a fixing bolt 102 having a fixing nut 104 at its lower end.

The fixing bolt 102 is a member connecting the universal joint 106 and the main shaft 70, the fixing nut 102 is interposed to induce a robust assembly.

A plurality of keys 108 are formed along the outer periphery of the upper end of the universal joint 106.

In addition, the universal joint 106 sufficiently absorbs the flow due to the eccentric rotation of the mantle 60.

The key 108 is inserted into the operation cylinder 110 to form a key combination to guide the operation cylinder 110 to perform a smooth rotational movement without flowing.

When the bearing 114 is supported and fixed by the fixing bracket 112 and the support bracket 116 on the outer periphery of the operation cylinder 110, each of the brackets 112 and 116 is fixed to the spider cap 20.

Therefore, the operation cylinder 110 can be smoothly rotated by the bearing 114.

Rotating plate 118 is seated on the upper end of the operation cylinder 110, the rotating plate 118 is fixed to the upper surface of the operation cylinder 110 by the stopper 122 and the bolt 124.

A plurality of protrusions 120 protrude from the upper surface of the rotating plate 118 at predetermined intervals in the circumferential direction, so that the protrusions 120 form a substantially triangular shape.

The present invention made up of such a configuration works as follows.

When the transported raw ore falls into the hopper 190, it is scattered in the circumferential direction of the hopper 190 by the rotating rotating plate 118.

That is, the falling raw ore is uniformly scattered by the rotating plate 118 without segregation to one side, in particular, the scattering amount becomes more uniform by the protrusions 120 protruding from the top surface of the rotating plate 118. .

Evenly scattered raw ore is charged to the crushing portion 45 in a uniform amount, and the raw ore is charged in a uniform amount almost corresponding to the circumferential direction of the crushing portion 45, the concay brewer 40 And the mantle liner 50 is reduced and expanded with the raw material ore interposed therebetween, even if abrasion occurs when the raw material ore is crushed.

As described above in detail, the unweared crusher of the raw material processing equipment according to the present invention is charged with a uniform amount of raw ore into which the unweared wear preventing member fixed to the main shaft is charged in a uniform amount along the circumferential direction of the crushed portion, thereby forming a cone. Suppressing uneven wear of K-Brainer and Mantleliner extends the service life of the facility, and also has the advantage of having abrasion resistance because the spyter cap, which is directly below the raw material ore, is protected by the rotating plate.
