Titanium concentrate detection method and green pellet detection method

Abstract

The invention relates to the field of pretreatment of a titanium concentrate, in particular to a titanium concentrate detection method and a green pellet detection method and provides a method for testing pelletizing performance of titanium concentrate as well as the titanium concentrate detection method and the green pellet detection method which are used for pelletizing material selection and have the advantages of high operability, high practicability and the like. The titanium concentrate detection method comprises steps as follows: a, particle size detection of the titanium concentrate: the titanium concentrate is weighed, and the particle size control range of pelletizing materials is 70%-98% of -200 meshes and 32%-85% of -325 meshes; b, wetting rate detection of the titanium concentrate: the titanium concentrate is added to a measuring cylinder, water is added to the measuring cylinder, the immersion volume in water is observed, a ratio of the immersion volume in water to time is taken as the wetting rate of the titanium concentrate, and the wetting rate of the pelletizing materials is controlled in a range of 2.5 mL/min-8.5 mL/min. The titanium concentrate detection method and the green pellet detection method have the characteristics of high operability, high practicability and the like and are particularly suitable for an industrial pellet production process.

Description

technical field [0001] The invention relates to the field of titanium concentrate pretreatment, in particular to a detection method for titanium concentrate and a green ball detection method. Background technique [0002] From the 1950s to the 1970s, researchers in the former Soviet Union and the United States successively proposed the static spheroidizing index and the dynamic spheroidizing index to quantitatively evaluate the spheroidizing performance of iron concentrates. However, these test methods have little effect on the actual spheroidizing process guidance is limited. Since 2010, Central South University has done a lot of research on the pelletizing performance of iron concentrates. Most of the test methods are based on the static pelletizing performance index as an indicator for evaluating the pelletizing performance. This test method mainly focuses on theory and does not provide much guidance for practical applications. . It can be seen from the literature repor...

Since 2010, Central South University has done a lot of research on the pelletizing performance of iron concentrate. Most of the test methods are based on the static pelletizing performance index as an index for evaluating the pelletizing performance. This test method mainly focuses on theory and does not provide much guidance for practical applications.

It can be seen from the literature reports and book review that the research is mainly on the pelletizing performance of iron concentrate, but there are few reports on the test methods and performance indicators of titanium concentrate pelletizing performance.
