The present invention relates to a hammer crusher that is used to crush crushed material to a certain particle size or less in a crushing stone site or a production site for producing recycled aggregates from construction wastes. It is very easy to control the gap between the Losstols arranged at a certain gap with respect to the rotational trajectory of the hammer tip, so the maintenance of the device is very easy due to the hammer wear, and the work delay is minimized due to the maintenance of the device. The clearance control device of the hammer crusher can maximize the yield.

In general, the process of collecting aggregates uses waste crusher or crusher to remove the waste concrete of quarries or mines from explosives such as dynamite, etc. Crushing process.

Commonly known crushers used in the grinding process include jaw crushers for crushing a relatively large mass of aggregates, and hammer crushers for crushing aggregates crushed from such jaw crushers into smaller sizes. .

In the above, the hammer crusher is a hammer that is installed on the outer periphery of the rotating rotor (rotary disk) to crush the raw stone, that is, the crushed material to have a particle size of less than a certain size by centrifugal strike due to the rotation of the hammer. The apparatus generally has a configuration as shown in FIG. 1.

That is, FIGS. 1A and 1B are front and side cross-sectional views showing the configuration of a hammer crusher generally known in the art. As shown therein, the hammer crusher according to the prior art includes a gemstone inlet 210 and an outlet port opposite to the inlet. A pulley 100 for power transmission is provided outside the case 200 having a 220, and the rotary shaft 110 is connected to the case 200 while the tip of the rotary shaft 110 is placed on the central axis of the pulley 100. ) Is extended inside. On the rotating shaft 110 in the case 200, a plurality of rotors 300 in the form of a disc having a hammer mounting groove 302 are installed at equal intervals, and the circumference of the rotor in the mounting groove 302 of the rotor The hammer 310 is provided at equal intervals in the direction and is configured as a pin 312 fixed.

Therefore, in the conventional hammer crusher, the rotor 300 rotates by the rotation of the rotary shaft 110 interlocking with the pulley 100, and the centrifugal force is generated while the hammer 310 also rotates with the rotation of the rotor 300. To be crushed by centrifugal blown the injected crushed material.

At this time, the rotation path of the tip of the hammer 310 according to the rotation of the rotor 300 and a predetermined gap, the inner wall surface and the discharge port side of the crushing plate 400 having irregularities (凹凸) and rounded rostol (Losstol) 410 are respectively installed, the crushed object bounced into the case by the hammering force collides with the crushing plate 400 and the rostol 410 to be crushed again, the crushed object crushed to a predetermined particle or less Pass through the rostol 410 to the outlet 220 side.

That is, the rostol 410 is a hammer net and the rostol 410 as well as a sieve for allowing only the crushed material having a predetermined particle size or less among the crushed materials crushed by the hammer to be discharged to the outside through the outlet 220. The crush plate serves to crush the crushed material located in between.

At this time, the size of the crushed matter (the size after crushed crushed object) discharged through the hammer crusher as described above is determined by the gap G between the rotational trajectory of the hammer tip and the rostol.

However, in the case of the pulverized material to be input, the hardness and the strength are different depending on the material thereof. In the case of crushing the crushed material having a very high hardness, the wear period of the hammer is shortened, so the maintenance period of the device is shortened. . Therefore, since the worker only needs to periodically change the installation position of the hammer on the rotor to replace the hammer or compensate for the gap, a lot of manpower is consumed and additional problems such as work delay due to the installation position change occur.

In addition, by simply re-installing the worn hammer in the long hole provided in the rotor, by adjusting the gap of the device, it is difficult to produce a good quality aggregate having the desired particle size because the gap is not precisely adjusted and the gap precision is low. There are many problems.

The present invention has been made in view of the above-described problems of the prior art, and the gap adjusting device is provided by providing a gap adjusting device on one side of a Losstol disposed at a predetermined gap with respect to the rotational trajectory of the hammer tip.
