BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing crusher apparatus, and more particularly, to a crushing crusher apparatus for crushing an ore produced from a scraper or a mine discharged from a steelworks.

Steel mills now release scrap iron, including iron and slag.

The iron and slag contained in the scrap iron now can be recycled, and it is necessary to crush them to a predetermined size and separate them.

Korean Unexamined Patent Publication No. 2002-0074430 (Mar. 30, 2002) discloses "Method and apparatus for producing aggregate using steelmaking slag ".

The present invention relates to a method for manufacturing a slag raw material slag, comprising the steps of: preparing a steel slag raw material slag raw material slag raw material slag raw material slag raw material slag raw material slag; And a first magnetic separator and a second magnetic separator for separating iron from the steelmaking slag.

As a result, recycled aggregate is recycled to prevent damage to the natural environment and to reduce the transportation distance when constructing in the area, and to reduce the cost of public transportation and to completely shred steel slag (steel scraps) The present invention can provide a method and an apparatus for producing aggregate using steelmaking slag capable of obtaining excellent aggregate by aging the product in the aging area for removing sulfur.

However, in this prior art, a plurality of grizzly feeders, magnetic separators, and conveyor belts are disposed in the longitudinal direction to remove scrap and slag of a desired particle size can be separated, but the above- There is a problem that further addition is required.

In addition, there is a risk of occurrence of a safety accident, such as a risk of slag falling, because the equipment is increased in the longitudinal direction as much as the number of stages added.

Further, in this prior art, it is very difficult to separate the scrap iron from the slag and iron components, and since the conveyor belt section is very long and is arranged in the longitudinal direction, the surface of the conveyor belt There are various problems such as breakage.

Meanwhile, FIG. 1 is a view showing a process of crushing and separating scrap iron.

As shown in FIG. 1, the scrap iron separation system has heretofore separated the scrap metal from the scrap metal now and transports the scrap metal of a predetermined size or less to the dump truck (D) And a separation line to separate the iron and the slag.

 Now, the scrap crushing and separation line is connected to hopper 1, scalping screen 2, magnetic force separator 3a, 3b, 3c, 3d, 3e, 3f, jaw crusher 4, lamination screen 5, 6).

Now, scrap iron of 300 mm or less is injected into the hopper 1 by the forklash P, and this now scrap is separated into scrapping screen 2 and now scrap of less than 50 mm and now scrap of more than 50 mm.

Now scrap iron of 50 mm or less is conveyed on a conveyor belt connected to one side of the scalping screen 2 to sequentially separate iron components from the fifth magnetic force separator 3e and the sixth magnetic force separator 3f installed on the conveyor belt , The rest of the slag falls on the yard.

The scrap iron now more than 50 mm is carried on a conveyor belt connected to the other side of the scalping screen 2 to separate small iron components through a first magnetic separator 3a installed on the conveyor belt.

Since scrap iron having a diameter of 50 mm or more is present in the form of agglomerates having a predetermined size or larger by mixing iron and slag, it is necessary to crush the scrap now and in a separable state.

To this end, the jaw crusher (4) is installed on the conveyor belt.

In JO crusher (4), more than 50mm of scrap is supplied and crushed.

The crushed now scrap is conveyed on a conveyor belt so that after the small iron component is separated in the second magnetic separator 3b, the scrap iron of 25 mm or less, the scrap metal of 25 to 40 mm and the scrap metal of 40 mm or more It is now separated by scrap iron.

Now, the scrap iron having a diameter of 25 mm or less passes through the fourth magnetic separator 3d and the remaining slag is placed on the yard. Now, the scrap metal of 25 to 40 mm passes through the third magnetic separator 3c, After the component is removed, the remaining slag is placed on a separate yard. Now, the scrap metal of more than 40 mm is rubbed on the conveyor belt and finely broken in the rod mill 6, then moved on the conveyor belt, 3b) and the lamination screen (5).

However, such a conventional scrap iron separation system requires a vast space for constructing the system. Even if the equipment is constructed, a very long conveyor belt is used. Therefore, when the belt is damaged, And there is a problem that causes disruption to continuous production.

In addition, since the installation space is vast, there is a problem that equipment and energy loss are large and the cleaning space is expanded. Especially, there is a problem that only the scrap metal of 50 mm or less is targeted.

In addition, the conventionally used jaw crusher 4 has a problem that the plate-type base material can not be crushed and the crushing efficiency is very low.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

2 and 3, the crushing and sorting system for maximizing the industrial waste and scrap metal purity of the present invention comprises a hopper 100, a hydraulic crusher 200, a jaw crusher 300, a first magnetic force A separator 400, a stacked filter 500, a rod mill 600, and a second magnetic separator 700.

A small sized scrap is now fed through the hopper 100 and a large sized scrap is now fed through the hydraulic scrapper 200. The hydraulic scrapper 200 scrapes the large scrap now to make it smaller.

The scrap now crushed in the hopper 100 and the hydraulic crusher 200 is fed to the jaw crusher 300.

The jaw crusher 300 is supplied with the supplied scrap iron and then supplied to the first magnetic separator 400. In the first magnetic separator 400, only the iron component is separated by using magnetism, To the stacked filter (500).

Now, even if you crush scrap in Joe Crusher (300), the grain size of all the scrap can not be made uniform now. That is, the iron content is separated through the first magnetic separator 400 as well as the grain size of the scrap iron is still uneven, but the iron content remaining in the slag and agglomerated state remains.

After passing through the first magnetic separator 400, the scrap metal now passes through the stacked filter 500.

In the present invention, the three-layered filter 500 is formed, and the sizes of the meshes formed in the respective layered filters 500 are different. That is, now the scrap metal of 40 mm or more is separated by the filter at the uppermost end, and now scrap metal of 40 mm or less dropped from the top is separated into 25 to 40 mm of now scrap metal and 25 mm or less of scrap metal by the filter located at the stop. The filters of the respective layers constituting the stacked filter 500 are inclined so as to facilitate the movement of the filtered scrap now.

Further, a separate filter may be provided at the top of the stacked filter 500 to feed the untreated scrap metal of 300 mm or less to the rod mill 600 to be described later.

In this way, scrap metal is now separated into three types and moved to different routes.

The iron scraps in the stacked filter 500 that are separated from the scraped iron of the first magnetic force splitter 400 or more than the filtered reference value of 40 mm or more (300 mm or less) are supplied to the rod mill 600, It is crushed finely.

The scrap iron finely ground in the rod mill 600 is separated from the iron component by the second magnetic separator 700. The separated iron component corresponds to the refined iron component and is stored separately.

Even if the iron component is separated in the second magnetic separator 700, the iron component may still remain in the scrap iron. The remaining scrap is re-supplied to the stacked filter 500, and by repeating the above- It is perfectly separable.

The third magnetic separator 800 is disposed on the first conveyor belt C1 so that the first magnetic separator 400 separates the iron component once again from the scrap that is separated from the iron component. That is, the iron component is separated in the second order and transferred to the yard with pure slag remaining.

The vibrating feeder may be separately provided at the lower ends of the second magnetic force separator 700 and the third magnetic force separator 800. There is a problem in that when the fine slurry contained in the aggregate conveyed by the conveyor belt is covered with other byproducts, the slurry can not be sorted by the magnetic force. Therefore, the vibration feeder distributes the aggregate smoothly and evenly, Thereby creating a separable state.

The now scrap metal of 25 to 40 mm is transported to the yard on the second conveyor belt C2.

The fourth magnetic force separator 900 is disposed on the second conveyor belt C2 so that the first magnetic force separator 400 separates the iron component from the scrap iron once again separated from the iron component. That is, the iron component is separated in the second order and transferred to the yard with pure slag remaining.

In the present invention, one end is connected to the third magnetic force separator 800 and the other end is connected to the first magnetic force separator 700 via the fourth magnetic force separator 900, the rod mill 600 outlet, And a circulating conveyor belt (RC) connected to the conveying belt (400).

Thus, by installing the circulating conveyor belt RC, the scraping of the scrap iron, the crushing at the rod mill 600, and the iron component separation operation at the third magnetic separator 800 and the fourth magnetic separator 900 are performed As a result, it is possible to obtain a refined iron component and slag, as well as to minimize installation space of the facility.

The hopper 100 and the jaw crusher 300 are connected to each other via a first feeder F1 and one side of the jaw crusher 300 and the circulating conveyor belt RC are connected to each other via a second feeder F2 A screen for sorting the iron component separated by the second magnetic separator 700 into two types of iron components on the basis of the 8-mm particle size as the reference, and a lower one on the side of the circulating conveyor belt RC S and two kinds of iron components classified on the screen S are separately stored in a silo R provided on the other side of the circulating conveyor belt RC so that highly purified iron components can be obtained.
