Problems solved by technology

Although the dust removal ash contains useful ingredients for titanium slag production, due to the low grade and fine particle size of the dust removal ash, there is no good way to use it. It is usually discarded as waste in the garbage dump of the industrial park. A large titanium slag Production enterprises will discard about 5,000-6,000 tons of dust ash every year, which not only causes a waste of resources, but also needs to pay 20-30 yuan / ton of garbage disposal fees

preparation example Construction

[0008] The present invention provides a method for preparing titanium concentrate pellets. The method includes: mixing titanium concentrate, liquid binder, and dust removal ash and pelletizing, wherein the dust removal ash is a titanium smelting slag in the process Dust removal ash produced in titanium slag electric furnace.

[0009] In the process of smelting titanium slag, the feeding process is carried out from the feeding hole on the furnace cover of the electric furnace. The furnace cover is 4-5m high from the lower molten pool, and the furnace cover is equipped with a dust removal system exhausting fume hood. There are usually many fine powders in the raw materials of titanium slag electric furnaces. When feeding, the fine powders are difficult to fall and float over the molten pool in the furnace. The fine powders are pumped away with the flue gas generated by the reaction in the furnace, and then enter the dust removal system. Collected, it is the dust removal ash describ...

Embodiment 1

[0028] This example is used to illustrate the preparation method of titanium concentrate pellets provided by the present invention.

[0029] Raw materials: titanium concentrate, particle size of 0.074mm; liquid binder, containing 23% by weight starch gum, 2% by weight sodium carboxymethyl cellulose and 75% by weight of industrial water; dust removal ash, particle size of 0.063mm. The weight ratio is, titanium concentrate: liquid binder: dust removal ash = 100: 2.0: 3.0.

[0030] First put the titanium concentrate and dust removal ash into the mixer according to the ratio of 100:3.0, mix in the dry powder state for 5 minutes, and then add the liquid to the mixer according to the weight ratio of titanium concentrate: liquid binder = 100: 2.0 The binder is mixed for a total mixing time of 30 minutes, and then the three mixtures are added to the ball press using a 60KN linear pressure to be extruded to a size of 20×25×18mm, and then added to the dryer to dry at 230°C for 60 minutes. F...

Embodiment 2

[0032] This example is used to illustrate the preparation method of titanium concentrate pellets provided by the present invention.

[0033] Raw material: titanium concentrate, particle size of 0.08mm; liquid binder, containing 24% by weight starch gum, 3% by weight sodium carboxymethyl cellulose and 73% by weight of industrial water; dust removal ash, particle size of 0.075mm. The weight ratio is titanium concentrate: liquid binder: dust removal ash=100:2.3:2.5.

[0034] First add titanium concentrate and dust removal ash into the mixer at a ratio of 100:2.5, mix for 10 minutes in a dry powder state, and then add liquid to the mixer according to the weight ratio of titanium concentrate: liquid binder = 100: 2.3 The binder is mixed for a total mixing time of 35 minutes, and then the three mixtures are added to the ball press using a line pressure of 50KN to be extruded to a size of 20×25×18mm, and then added to the dryer to dry at 250°C for 50 minutes. Finally, the titanium concen...

Abstract

The invention provides a method for preparing titanium concentrate pellets. The method comprises the following steps: mixing titanium concentrate, a liquid adhesive and collected dust, and pelleting, wherein the collected dust is generated from an electric titanium slag furnace in a titanium slag smelting process. By adopting the method, the collected dust of the electric titanium slag furnace can be sufficiently utilized, the resource is saved, and good economic benefits are achieved. The pellet manufactured by using the method is high in pellet rate and good in pressure resistance.

Description

Technical field [0001] The invention relates to a method of pelletizing, in particular to a method of using titanium slag electric furnace dust removal ash to produce pellets of titanium concentrate. Background technique [0002] In the current process for producing titanium slag, large-scale titanium slag electric furnaces are usually used for smelting. A large amount of dust removal ash will be generated in the titanium slag electric furnace, especially when the raw materials into the furnace contain fine powders, a large amount of fine powders will follow The furnace gas enters the dust removal system, and the amount of dust removal ash generated is greater. Although the dedusting ash contains useful components for the production of titanium slag, due to the low grade and fine particle size of the dedusting ash, there is currently no good way to use it. It is usually discarded as waste in the garbage dump of the industrial park. A large titanium slag Production companies will...
