Pelletizing device for titanium concentrate

Abstract

The invention relates to the technical field of titanium concentrate smelting, in particular to a pelletizing device for a titanium concentrate. The pelletizing device comprises a rotating main barrel, the main barrel is divided into a front section barrel body, a middle section barrel body and a rear section barrel body, the middle section barrel body is in a cylindrical shape, a plurality of rows of mutually parallel pelletizing structures are arranged on the surface of the inner wall of the middle section barrel body in the length direction of the middle section barrel body, each row of pelletizing structures is composed of a plurality of cylindrical shoveling plates, and the cylindrical shoveling plates in each row of pelletizing structures are evenly distributed in the circumferentialdirection of the middle section barrel body. According to the pelletizing device for the titanium concentrate, the structure is simple, the cost is low, and the pelletizing device is particularly suitable for conducting pelletizing on micro-fine-particle-grade titanium concentrates.

Description

technical field [0001] The invention relates to the technical field of titanium concentrate smelting, in particular to a granulation device for titanium concentrate. Background technique [0002] Vanadium-titanium magnetite undergoes a series of processes such as crushing, grinding, and sorting. First, the iron concentrate (with a TFe content of about 54% and a TiO2 content of about 12%) is selected, and the iron concentrate is generally smelted in a blast furnace. The tailings after iron selection enter the titanium selection process. At present, the titanium selection process adopts the method of separate treatment of coarse-grained tailings and fine-grained tailings. After several steps such as weak magnetic iron removal, strong magnetic titanium separation, and flotation Finally, titanium concentrate (TFe content about 30%, TiO2 content about 47%) is obtained. Since the titanium concentrate is obtained by further grinding and sorting the iron beneficiation tailings, its...

AI Technical Summary

Problems solved by technology

[0004] Since the final process of titanium concentrate sorting is flotation, the titanium concentrate has the property of hydrophobicity, which makes it difficult to granulate and pelletize titanium concentrate. It is necessary to use a high-pressure briquetting machine. The preparation cost of the high-pressure briquetting machine is high. Among them, the roller skin wears quickly, the operating cost is also high, and the prepared particle size contains high moisture, and then the air permeability is poor during sintering, which increases the sintering time and the strength of the finished product is poor.
