Description

Technical Field

[0001] The present application relates to the technical field of granulators, and in particular to a large ball crushing device for a copper concentrate granulator. Background Art

[0002] With the continuous improvement of the copper smelting capacity of the smelter, the discharge capacity of the Isa furnace has increased, and the instantaneous amount of material entering the granulator has increased. In order to ensure that the powdered material can be granulated in a short time, a large amount of water is needed to help the particles form balls. The moisture content of the particles is controlled to between 9-10%. Although the material can be quickly balled, it also causes the sticky materials on the granulator plate to continue to stick after being scraped, forming large balls. The diameter of this type of large ball is between 50mm-130mm. It is not easy to melt when entering the Isa furnace, which makes it difficult to discharge, increases the labor intensity of cleaning up leaked materials, and has a high safety risk.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] With the continuous improvement of the copper smelting capacity of the smelter, the discharge capacity of the Isa furnace has increased, and the instantaneous amount of material entering the granulator has increased. In order to ensure that the powdered material can be granulated in a short time, a large amount of water is needed to help the particles form balls. The moisture content of the particles is controlled to between 9-10%. Although the material can be quickly balled, it also causes the sticky materials on the granulator plate to continue to stick after being scraped off, forming large balls. The diameter of such large balls is between 50mm-130mm, and it is not easy to melt when entering the Isa furnace, which makes it difficult to discharge the Isa, increases the labor intensity of cleaning up leaked materials, and has a high safety risk.

[0024] In view of the above problems, an embodiment of the present application provides a large ball crushing device for a copper concentrate granulator, which can crush the large balls remaining behind the large ball cleaner of the granulator into pieces within 30 mm through the toothed cutter installed on the rear side of the large ball cleaner. After the copper concentrate balls smaller than 30 mm enter the Isa furnace, the small particles can be quickly melted in the furnace, thus preventing the large balls from entering the Isa furnace, shortening the discharge cycle of the copper concentrate balls entering the Isa furnace each time, and improving the production output.

[0025] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0026] Figure 1 It is a schematic structural diagram of a large ball crushing device of a copper concentrate granulator shown in an embodiment of the present application.

[0027] See also Figure 1 , a large ball crushing device for a copper concentrate granulator, comprising:

[0028] Spur cutter bearing seat 1, bearing 2, purger shaft 3, purger 4, pelletizing disc 5, large ball cleaner 6;

[0029] The toothed cutter bearing seat 1 is bolted to the rear bracket of the large ball cleaner 6, and the inclination angle of the toothed cutter bearing seat 1 is adjustable. The toothed cutter shaft 3 is bolted to the top of the toothed cutter bearing seat 1, and the toothed cutter 4 is equidistantly rotatably fixed to the toothed cutter shaft 3 through the bearing 2. The top of the toothed cutter 4 is 1-30mm away from the surface of the granulating disk 5 of the copper concentrate granulator, which is convenient for crushing the large-diameter balls of the copper concentrate when the granulating disk 5 rotates. The toothed cutter 4 is installed in a six-blade windmill type on the bearing 2, and the front end of the toothed cutter 4 is bent to one side to increase the crushing area.

[0030] The toothed cutter 4 rotates with the inertia of the granulating disk 5, and the large balls remaining behind the large ball cleaner 6 of the granulator are crushed into pieces within 30 mm. After the copper concentrate balls smaller than 30 mm enter the Isa furnace, the small particles can be quickly melted in the furnace, avoiding the problem of difficulty in Isa discharge caused by the large balls entering the Isa furnace being difficult to melt. The discharge time of the copper concentrate balls entering the Isa furnace is shortened from 1 hour to within 30 minutes per discharge, shortening the discharge cycle and effectively improving the production output.

[0031] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
