Double-cylindered magnetite fine powder grade improver

Abstract

The embodiment of the invention discloses a double-cylindered magnetite fine powder grade improver, comprising a driving device, an outer cylinder, a discharging device, a support frame and an inner cylinder, wherein the driving device comprises a driving motor, a transmission shaft and a bearing bracket; the upper end surface of the outer cylinder is provided with an annular water distributor; the upper end of the annular water distributor is provided with an annular material distributor; and the side surfaces of the annular distributor and the annular water distributor are provided with a material inlet and a water inlet respectively. A clearance space between the outer cylinder and the inner cylinder of the double-cylindered structure increases the contact area between the magnetite material and the clean water and increases the washing speed of the slurry. A plurality of magnets are annularly arranged side by side to define a cylindrical inner cylinder permanent magnet mechanism soas to increase the magnetic separation area and increase the number of mineral rubbing and overturning times. The outer cylinder is provided therein with a scraper arranged in a spiral shape to scrape off the fine iron powder in the outer cylinder downward. The water rinses the fine iron powder from the bottom to the top to achieve efficient wet magnetic separation. The double-cylindered magnetite fine powder grade improver improves work efficiency and is easy to operate.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of mining processing equipment, in particular to a double-barreled magnetite fine powder grade hoist. Background technique [0002] In the field of mining production and processing, the process of crushing and screening iron ore and separating refined iron powder is an indispensable and important link. Most of the existing technologies use wet drum magnetic separation. The work of the existing magnetic separator The principle is: after the ore slurry flows into the tank through the ore feeding, the ore particles enter the ore feeding area of ​​the tank in a loose state under the action of the water spray pipe for the ore feeding, and under the action of the magnetic field, the magnetic ore particles move to the magnetic poles and are Adsorbed on the cylinder, since the polarities of the magnetic poles are arranged alternately along the direction of cylinder rotation, and they are fi...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a double-barrel type magnetite fine powder taste hoist to solve the problems in the prior art that the iron powder adsorption is not in place due to the single structure of the permanent magnet and the scraper of the magnetic separation equipment, and the scraper The problem of not being able to separate efficiently and increasing the cost due to the addition of multiple sets of magnetic separation mechanisms
