Schreyerite ore-dressing device

Abstract

The invention relates to the field of mining machinery, in particular to a schreyerite ore-dressing device. In order to solve the technical problems, the invention provides the schreyerite ore-dressing device which is low in cost and is sufficient in ore-dressing. The schreyerite ore-dressing device comprises a grinding device and a screening device, and further comprises an inclination slot, wherein a charge hole is formed in the upper end of the grinding device; a discharge hole is formed in the lower end of the grinding device; rotary shafts are symmetrically arranged in the grinding device; rotor discs are arranged on the rotary shafts; tooth rollers are mounted on the rotor discs; a primary sieve plate is arranged inside the screening device; a secondary sieve plate is arranged below the primary sieve plate; the primary sieve plate and the secondary sieve plate are equipped with through holes which are densely arranged, and diameters of the through holes are sequentially reduced; one end of the inclination slot is connected with the discharge hole, and the other end of the inclination slot extends into the screening device; and the grinding device can be used for effectively grinding schreyerite ores, and small ground ores enter the screening device, so that schreyerite ores of different sizes are effectively screened out, screening is sufficient, production cost is reduced, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a vanadium-titanium ore beneficiation device. Background technique [0002] Vanadium-titanium ore is an irreplaceable basic material in the development of national strategic and pillar industries. After beneficiation, it can be processed into titanium magnetite concentrate (containing vanadium) and ilmenite concentrate, which are widely used in steel industry, aerospace, national defense With the rapid development of high-tech fields such as industry and defense cutting-edge industries, the demand for vanadium-titanium magnetite resources is increasing day by day; Ore, the existing vanadium-titanium ore beneficiation technology, in the beneficiation process, the crushing is not complete, which increases the work intensity of the grinding stage, thereby increasing the production cost and reducing the work efficiency to a certain extent.
