Embodiment Construction

[0016] Using Tongling specular iron ore powder in Anhui Province as raw material, the iron content after beneficiation is greater than 65 (mass fraction).

[0017] Such as figure 1 As shown, a dry processing method of mica iron oxide includes a raw material storage device, and the raw material storage device is connected to a super vortex mill main engine, an ultra-fine classifier, a cyclone classifier, a bag filter and a fan in sequence through pipelines. The processing method comprises the following steps:

[0018] (2) After the raw material specularite powder is dried, it enters the main frame of the super vortex mill through a feeder to be pulverized, the feeding speed of the feeder is adjusted to be 30kg / min, and the rotating speed of the super vortex mill main frame is set to Set at 2632r / min;

[0019] (2) the rotating speed of setting blower fan is 1043r / min, and the material after pulverizing enters superfine classifier under the drive of airflow, regulates the gradi...

Abstract

The invention provides a micaceous iron oxide dry-method processing method. The micaceous iron oxide dry-method processing method comprises the following steps that firstly, a raw material specular hematite powder is dried and then enters a super eddy mill mainframe through a feeder to be smashed; secondly, the smashed material enters a superfine classifier, the classification particle size of the superfine classifier is adjusted, secondary classification is carried out, and coarse products 1 are discharged through a discharge opening in the lower portion of the superfine classifier; thirdly, fine powder products enter a cyclosizer from the superfine classifier in the second step to be separated, and products 2 are discharged; and fourthly, micro powder products with too-small particle size enter a bag-type dust collector from an outlet in the upper portion of the cyclosizer in the third step, and the bag-type dust collector collects products 3. According to the micaceous iron oxide dry-method processing method, by optimizing operation parameters, the prepared mica iron oxide product is large in sheet structure content, smaller in average particle size, relatively narrow in particle size range and capable of achieving the purpose of producing iron oxide red and oxide iron grey at the same time.

Description

technical field [0001] The invention relates to the technical field of mica iron oxide processing, in particular to a dry processing method of mica iron oxide. Background technique [0002] Mica iron oxide is a special iron ore in nature with ferric oxide as the main chemical composition. Its crystallization state is similar to mica, and its structure is scale-like, gray-black, with metallic luster. Due to its unique scaly structure, iron oxide ash (light gray or dark gray) and iron oxide red (rust red) prepared by crushing, ultra-fine processing, and sorting are mainly used as pigments and fillers for anti-corrosion coatings. The traditional mica iron oxide crushing process is complicated, the crushing effect is not good, the particle size range is relatively wide, and the sheet structure of mica iron oxide will be destroyed. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to provide a dry processing meth...
