Method and system for quickly crushing, grinding and grading high titanium slag

Abstract

The invention discloses a method and a system for quickly crushing, grinding and grading high titanium slag, and belongs to the field of metallurgical production. The method comprises the following steps of: impacting and crushing a demolded and cooled high-titanium slag lump; crushing large blocks of the high titanium slag after impact crushing by a jaw crusher; adding water to wash and screen crushed small blocks through a drum screen, and returning oversize products to the jaw crusher to crush; the screen underflow enters a cone crusher to be crushed; after cone crushing, feeding into a 1 # water sieve for screening, and returning oversize products to a cone crusher for crushing; sieving the undersize product in a 2 # water sieve; 2 # oversize products enter a rod mill to be ground, and undersize products enter a 1 # grading water sieve to be graded; after grinding by the rod mill, feeding into a 3 # water sieve, returning oversize products to the rod mill for grinding, and feeding undersize products into a 1 # grading water sieve for screening; screening with a 1 # grading water sieve; and the oversize product and the undersize product are subjected to ultrasonic washing, filter pressing and drying respectively and then enter a chlorination residue bin and an acid residue bin. The method has the advantages of short process flow, less return quantity, large treatment capacity, reduction of flying dust, improvement of production environment and the like.

Description

technical field [0001] The invention belongs to the field of metallurgical production, and in particular relates to a method and a system for rapid crushing, grinding and classification of high-titanium slag. Background technique [0002] Titanium slag is commonly known as titanium ore enrichment formed by chemical reaction process. Titanium ore is heated and melted by electric furnace, and titanium concentrate is smelted by electric furnace heating. Titanium oxide in titanium concentrate and reducing agent (coke, anthracite, blue Carbon) undergoes a chemical reaction to generate TiO2. Due to the difference in specific gravity, the slag and iron are separated to obtain a titanium-rich material (titanium slag). The high-titanium slag is neither waste residue nor by-product. High-titanium slag needs to be crushed, ground, classified and other processes to produce products with qualified particle size. [0003] In the prior art, the use of dry treatment will lead to a large am...

Problems solved by technology

[0003] In the existing technology, the use of dry processing will lead to a large amount of dust in the production workshop, the working environment of the employees is poor, and it is difficult to clean; and the sampling and analysis during the processing process is difficult and lagging, and the control indicators cannot be constantly monitored, which affects the yield of finished products
