Description

Raw material feeder with separate crushing by particle size {AN RAW ORE FEEDER ABLE TO CONTROLL THE SEPERATION AND CRUSH WITH PARTICLE SIZE}

The present invention relates to a raw material light supply apparatus that can be separated and adjusted by particle size, more specifically, to improve the work efficiency by performing the sorting operation of the raw light through the screen and the grinding of the raw light through the crusher at the same time, the crushing of the raw light The present invention relates to a raw material light supply device capable of controlling particle size separation and crushing to smoothly supply raw material light in a post process by preventing uniformity of crushed raw material particles by preventing wear and pinching of the middle portion of the hammer.

In general, the process of transporting the raw light in the steel mill, as shown in Figure 1, the vibrating feeder (Vibrating Feeder) is installed at the bottom in the state in which the raw light is stored in the surge bin 110 having a predetermined internal space The emission of the raw light starts by the vibration of the 112.

In addition, the raw light emitted from the surge bin 110 through the vibrating feeder 112 may be used in the blast furnace while being supplied into the sorter 120 having a flat screen 122 having a grid of a predetermined size installed on the bottom. It is separated into a small ore and gangue which is an allele ore, the gangue is an ore with a particle size larger than the size of each lattice of the screen 122 does not pass through the bottom of the flat screen 122, the inclined screen ( Flowing downward on the 122, it is separated into the gangue box 126 through the gangue treatment chute 124 installed at the lower end of the screen 122.

On the other hand, small ore particles having a particle size smaller than that of each lattice of the flat screen 122 pass through the screen 122 and fall downward to the belt 132 of the belt conveyor 130 installed at the bottom of the sorter 120. ) Will be transported to the post-process.

Here, the opposing ore is supplied to a separate grinder feeder (not shown), crushed to 3 mm or less in the grinder, and then loaded on a grinder lower belt and transported to a process.

As described above, the raw material light is sorted into small and alleles, and the raw light stored in the surge hopper 110 is continuously discharged from the vibrating feeder 112 in the process of reprocessing the opposing ores. While supplying allel ore to the crusher and passing the supplied allel ore through the rotating hammer, it was pulverized for use as raw material in the blast furnace, while the supplied ore was passed through the rotating hammer inside the crusher. During the crushing process, the wear of the hammer occurs intensively in one part, and thus, the unevenness of the crushed particles is generated between the enlarged space between the heavily worn hammer and the repellent plate, thereby making it difficult to manage the proper particles.

Accordingly, when the wear between the hammers installed in the grinder deepens the wear to more than a predetermined interval, the replacement cost is excessively required and the inefficient work has been made since the whole hammers have to be replaced in a batch. Since the screen process and the shredding process must be performed in separate processes, there is a problem in that the work efficiency is lowered and the smooth material transportation is not performed.

Therefore, the present invention has been proposed in order to solve the conventional problems as described above, the object of which is to integrate the screen process of screening the raw light and the grinding process of grinding the raw light to improve the efficiency of the process, and Improve the work productivity by shortening the working time to sort and grind and supply to the post process, prevent the jamming of raw materials in the middle of hammer, and minimize the noise and dust generated during the crushing process to prevent environmental pollution, It is possible to provide a raw material light supply having a particle size, and to provide a raw material light supply device capable of adjusting the separation and crushing by particle size to improve the transport capacity of the raw light.
