Embodiment 1

[0038] 1. Primary screening of ore

[0039] The iron ore is crushed with a crusher, after dry grinding, the material is firstly separated by a friction vibration separator, and under the condition of vibrating by the first vibrator in one direction, the coarse separation of particle size classification is carried out by point blanking, and the 0.45-0.06 MM iron ore particles are divided into 0.1-0.06MM iron ore, 0.25-0.1MM iron ore and 0.45-0.2MM iron ore according to particle size. The vibration frequency of the first vibrator is 21HZ and the amplitude is 6mm .

[0040] 2. Enrichment of ore after rough separation

[0041]The three groups of iron ores separated above are transported to the dry separation and enrichment machine described in Example 1, and enriched by line blanking under the conditions of different airflows and the vibration of the second vibrator in one direction. , the vibration frequency of the second vibrator is 30HZ, and the amplitude is 0.3-3mm; the por...

Embodiment 2

[0045] The ilmenite, which is located in Dali, Yunnan, contains 60 mesh ilmenite with a content of 18%, and the ore particles below 0.1MM account for less than 1% of the ore content. Therefore, a simplified process is adopted, and only sand making machines are used. After peeling off the soil, directly enter the enrichment machine, directly use the dry separation enrichment machine described in Example 2, under the condition of passing through the air flow and the vibration of the second vibrator in one direction, enrich by line blanking, the resulting The vibration frequency of the second vibrator is 30HZ, and the amplitude is 0.3-3mm; the porous plate is provided with evenly distributed micropores, the distance between the micropores is <100 μm, and the diameter of the micropores is <30 μm.

[0046] Figure 4 It is a schematic diagram of the comparison results of the sediment and overflow after the separation of ilmenite. It can be seen from the figure that the separation ef...

Abstract

The invention relates to a dry-separation enrichment separation method (mainly used for particles less than 1mm) and a system applied to the method. The dry-separation enrichment separation method comprises the following steps: crushing ores by using a crusher, dry grinding, and enriching materials by using a dry-separation enriching machine under the condition of airflow introduction and single-direction vibration of a second vibrator, wherein an included angle between the second vibrator and the horizontal direction ranges from 20 degrees to 60 degrees, the dry-separation enriching machine forms a turbulence field through a perforated plate to separate materials, the included angle between the perforated plate and the horizontal direction ranges from 2 degrees to 20 degrees, and the thickness of the material is less than or equal to 40mm. The system comprises a material input device, a friction vibration separator and a dry-separation enriching machine, wherein the material input device is arranged above the friction vibration separator; at least two material conveying grooves are arranged below the friction vibration separator; and at least two material conveying devices are arranged above the dry-separation enriching machine.

Description

technical field [0001] The invention relates to a dry selection enrichment separation method and a system used for the dry separation enrichment separation method, belonging to the technical field of gravity separation. Background technique [0002] In the industrial production of mines, the target minerals are usually surrounded by rocks or exist in the soil, and are generally crushed and ground until the minerals are exposed to more than 90%. Chemicals are used in water to utilize the effects of the target on different chemicals. Relative relationship (there are exceptions, such as iron ore), go to sorting and enrichment, so that the mineral content reaches a certain concentration before smelting. [0003] Currently commonly used vibrating fluidized bed and jig. Among them, vibrating fluidized bed, people's research on it mainly focuses on the uniformity of fluidization and drying of tiny particles. Although it claims that particles with high density will sink to the bott...
