Embodiment

[0028]Such asfigure 1As shown, the preparation system of the vanadium-titanium pellets includes a grate machine, a rotary kiln 10 and a ring cooler which are connected in sequence.

[0029]Among them, the grate machine includes the communicating drum section 1, the exhaust section 2, the preheating section I 3 and the preheating section 4, the drum section 1 is the inlet end of the green ball, and the preheating section 4 is connected with The rotary kiln 10 is connected.

[0030]The preheating section 4 is also connected to the multi-tube dust collector 11, and the multi-tube dust collector 11 is also connected to two regenerative fans 12 at the same time. The regenerative fan 12 is connected to the exhaust section 2 at the same time; at the same time, in the regenerative fan 12 A cold air valve 8 is provided between the multi-tube dust collector 11.

[0031]In addition, the air extraction section 2 and the preheating section I 3 are in communication with the electric precipitator 13 at the...

Abstract

The invention discloses a preparation method and a preparation system of vanadium-titanium pellets. The system comprises a chain grate, a rotary kiln and a cooling fan which are communicated, the chain grate comprises a blow-drying section, an air draft section, a first preheating section and a second preheating section which are communicated in sequence, the preheating section II is communicatedwith the rotary kiln, the cooling fan comprises a first annular cooler section, a second annular cooler section and a third annular cooler section which are sequentially communicated, and the first annular cooler section is communicated with the rotary kiln. According to the preparation method and the preparation system of the vanadium-titanium pellets, a cold air valve is arranged, the air temperature and the air speed of each section can be controlled, and the original phenomenon that the air speed cannot be continuously increased due to high air temperature is improved, so that the temperature of each section is better controlled, the pellet drying, preheating, roasting and cooling effects are guaranteed, and high-yield and high-quality pellets are generated.

Description

Technical field[0001]The invention belongs to the technical field of preparation of vanadium-titanium pellets, and specifically relates to a preparation method of vanadium-titanium pellets and a preparation system thereof.Background technique[0002]As a composite iron ore resource, vanadium-titanium ore has a very high comprehensive utilization value. How to make good use of vanadium-titanium ore, give full play to the advantages of resources, and fully recover iron, vanadium and titanium has always been the goal of scientific researchers in metallurgy. Traditional blast furnace processes and foreign non-blast furnace processes smelt vanadium-titanium ore, and only iron and vanadium are recovered, while titanium enters blast furnace slag. Because the titanium grade is too low, there is no economic and reasonable recovery value, resulting in a large loss of titanium resources. The production process of vanadium-titanium pellets mainly includes four major processes: raw material pretre...
