Titanium concentrate grinding aid

Abstract

The invention discloses a titanium concentrate grinding aid, which is characterized by comprising the following steps: adding 25-30% of glycerol by mass ratio in a reaction container, adding 50-60% triethanolamine by mass ratio, adding about 15% of mixture of neutralized formic acid and sodium dodecanesulphonate, then mixing and stirring, wherein the stirring speed is 400-500rotation/minute and the stirring time is 1.5-2 hours, and obtaining the titanium concentrate grinding aid. The mass ratio of glycerol to triethanolamine to neutralized formic acid to sodium dodecanesulphonate is 4: 8: 1: 1. Addition of the grinding aid can solve the problem of electrostatic interaction generated during the grinding process of titanium concentrate, so that good grinding effect is reached, and power consumption is saved.

Description

technical field [0001] The invention relates to a grinding aid for granular powdery raw material grinding, which is an additive for promoting grinding in the ultrafine grinding process of coarse titanium concentrate, and belongs to the field of production and manufacturing. Background technique [0002] With the continuous development of the national economy, people's demand for titanium dioxide is also increasing. The raw material for most titanium smelting in China is ilmenite, especially the rich ilmenite in Yunnan. The domestic production of high-titanium slag is mainly prepared by reduction by circuit smelting, so the demand for titanium concentrate is very large. Using coarse titanium concentrate for smelting, the reduction temperature is very high, around 1000°C-1200°C, but using ultra-fine titanium concentrate for smelting, it can react quickly at a temperature of 650°C, so ultra-fine titanium concentrate powder is very important for smelting Energy saving plays a...

Due to the mutual attraction of static electricity, the particles are agglomerated with each other, and the phenomenon of ball holding and wall sticking occurs in the mill

Since a large amount of electric energy is converted into heat energy, the effective utilization rate of electric energy is only less than 20%, resulting in a large waste of electric energy
