Research Status of Granulation Technology Process of Fine-Grade Rich Titanium Material

Titanium resources are enriched to extract titanium and remove impurities to obtain titanium-rich materials that meet the requirements of boiling chlorination furnace charge. However, the fine-grade rich titanium materials make up a large part, and it cannot meet the particle size requirements of boiling chlorination furnace charge. The fine-grade rich titanium materials tend to cause problems such as channel flow, slugging and escapes from the furnace during boiling chlorination process, resulting in low boiling chlorination rate, inadequate reaction of the charge, and severely affects the stable running of boiling chlorination process. Therefore, granulating the fine-grade rich titanium materials to meet the requirements of the raw material particle size is one of the key issues in preparing high-quality boiling chlorinated furnace charge. This paper summarizes the granulation method of fine-grade rich titanium materials particles and the required binders in detail, analyzes the problems in the current granulation method of fine-grade rich titanium materials and the binders used, and points out that the use of inorganic or organic-inorganic composite binders with low consolidation temperature to fluidize granulation of fine-grained titanium-rich materials is beneficial to the development direction of industrialization.
