A titanium concentrate classifying device and its classifying method

Abstract

The invention discloses a titanium concentrate grading device and method. The titanium concentrate grading device comprises a high-position bin, a spiral feeding unit, a fluidized grading unit, a gas supply unit, a course-fraction titanium concentrate receiving unit, a fine-fraction titanium concentrate receiving unit and micro-fine-fraction titanium concentrate receiving unit which are connected through a pipeline. Gas is led into the fluidized grading unit, and the gas flow and the gas flow rate in the fluidized grading unit are adjusted so as to achieve grading of titanium concentrate. The titanium concentrate grading method is conducted by the adoption of the titanium concentrate grading device. For titanium concentrate which is wide in particle size distribution and small in particle size, the titanium concentrate grading device and method achieve rapid and efficient grading of the titanium concentrate by the utilization of the fluidized grading device, achieve grading of titanium concentrate of different particle sizes through adjustment of the gas flow and the gas flow rate in the fluidized process, and improve the utilization effect and the pertinence of the titanium concentrate.

Description

Technical field [0001] The invention belongs to the technical field of beneficiation and classification, and more specifically, relates to a classification device and a classification method for the titanium concentrate obtained after the beneficiation of Panxi vanadium-titanium magnetite. Background technique [0002] The reserves of vanadium-titanium magnetite in the world are very rich, and the reserves in our country are even among the best. The reserves in Panxi area alone are tens of billions of tons, and the total reserves of titanium resources rank first in the country. [0003] Panxi vanadium-titanium magnetite is a multi-element intergrowth ore. The ore contains 30-34wt% of iron (exists in the form of iron oxide in the ore). It is mainly used as a raw material for iron, vanadium, and titanium. Titanium concentrates in Panxi area belong to rock-type primary ilmenite, with iron metatitanate (FeO·TiO 2 ) Based on the crystal lattice, it contains solid solutions of oxide impu...

AI Technical Summary

Problems solved by technology

Among them, the main feature of mechanical vibrating sieve classification is that the particle size range of the classified powder is accurate, but the operation process takes a long time and consumes a lot of energy for materials with finer particle sizes, especially for viscous powders that are easy to block the net. And there are problems such as serious screen wear and high classification cost

The main feature of the cyclone-gravity classification method is that the operation process takes a short time, but there are problems such as the inaccurate particle size range of the classified powder and the large volume of the equipment.
