Description

A kind of wind concentrator

technical field

The utility model relates to a kind of mineral processing equipment, in particular to a wind-powered mineral processing machine, which is especially suitable for sorting mica, and belongs to the technical field of mining machinery and equipment.

Background technique

Wind beneficiation belongs to gravity beneficiation method. For a long time, gravity beneficiation has mostly been based on wet gravity separation (with water as the medium). Wet gravity separation equipment not only has many types, strong adaptability, but also has better and better performance. But at the same time, wind power beneficiation without water has always been a field of exploration.

Wind beneficiation is the process of separating mineral raw materials according to the difference in mineral density in the air medium. The particle size and shape of the particles also affect the separation. Compared with wet gravity separation in water medium, wind power dressing does not consume water, and the product does not need to be dehydrated, which can reduce the process of concentration, filtration and drying, and there will be no freezing phenomenon in winter transportation; moreover, the structure of wind power dressing equipment is simple, and the infrastructure Fees and operating costs are lower. Therefore, wind beneficiation has important significance and broad prospects for some arid and water-scarce areas and when raw materials are suitable for dry processing.

Wind beneficiation can be used for the beneficiation of some non-metallic ores, such as the separation of asbestos, mica and gangue, especially in the separation and recovery of mica.

Mica is a rock-forming mineral with a relatively smooth surface, strong adhesion, and a large diameter-to-thickness ratio. It is widely used in industry. Most of the mica contains other impurities, so it needs to be beneficiated. In the industry, natural mica crystals are mainly processed directly into required products. The larger the mica crystals without defects, the higher their economic value. Therefore, in the process of beneficiation of mica ore, it is necessary to protect the natural mica crystals from damage as much as possible. For the beneficiation of mica, in the past, it was mainly based on the difference in shape and friction coefficient between mica crystals and gangues. Traditional methods include hand selection, friction beneficiation, and shape beneficiation.

Manual selection means that workers select the mica that has been separated from the mining face or the ore pile at the pit mouth; the conjoined body of mica and gangue is crushed with a hand hammer, and then the mica is selected; this method has less investment cost , but labor-intensive and labor-intensive. Friction beneficiation refers to the separation of mica crystals and gangues based on the difference between the sliding friction coefficient of the flaky mica crystals and the rolling friction coefficient of the round gangue; the equipment used is a friction plate; the friction beneficiation equipment is not yet perfect, so In the beneficiation of mica ore, this method has not been widely used. Shape beneficiation is based on the different shapes of mica crystals and gangue, and the ability to pass through the sieve gaps and holes of the sieve during screening, so that mica and gangue are separated; the equipment used is a kind of more than two layers of different screen surface structures. Sieve; its disadvantage is that heavy minerals and light minerals are not easy to sort, and the phenomenon of mineral mixing is serious.

To sum up, the traditional mica beneficiation methods and equipment mainly have the following two major problems: 1. It is only suitable for minerals with large particle size, resulting in serious waste of resources, low production capacity, low recovery rate, and high cost; 2. Processing The quantity is small, the equipment is large, the process is discontinuous, and it is difficult to large-scale and large-scale production, resulting in irregular replacement of consumables, high work intensity, and high sorting costs. The existence of these problems promotes the continuous improvement of sorting equipment and the creation of utility models. According to the principle of different stresses on mineral shape rules, wind concentrators have greatly improved and improved in terms of making full use of resources, increasing production capacity, improving recovery rate, increasing processing capacity, reducing consumables, reducing labor intensity, and reducing production costs. improve. Therefore, this provides space for the application and development of wind power beneficiation, and at the same time puts forward higher requirements for wind power beneficiation machines.

The core of wind separation technology is wind separation machine, whose structure and performance directly affect the separation effect. If the wind concentrator can make further breakthroughs, it will undoubtedly be a revolutionary change for the development and utilization of mica resources at home and abroad.

In view of this, the utility model is proposed.

The utility model can well adapt to the drought and water shortage conditions in this area, improve resource utilization rate and product quality, and stabilize and expand production scale. The density difference between vermiculite and gangue minerals is very small, and the traditional wet gravity separation method cannot effectively separate them. The utility model can make full use of the difference in shape and structure to separate vermiculite. It has the advantages of less investment in equipment, easy operation, no need for water, no need for dehydration and drying, and low production cost.

The utility model can be used for discharging gangue of power coal with low commercial coal ash content, increasing calorific value, and also for removing massive pyrite sulfur in high-sulfur coal. The utility model avoids the disadvantages that the wet method of coal preparation increases the water content of the product and is not suitable for the separation of easy-mud lignite, and the wind-forced dry method of coal preparation technology in arid and severe cold regions has special significance.

Application 4: Separation of products in the sintering process

After the sintered ore is unloaded from the sintering trolley, it needs to be crushed, cooled and then classified to separate the sintered ore, returned ore and bottoming material. The utility model makes full use of the particle size difference, and can complete the grading of 5-50mm finished sintered ore, 10-20mm bottoming material and -5mm cold-returned ore.

Use occasion 6: asbestos selection

The friction beneficiation method has been used in the separation of asbestos. It uses the difference in the frictional elasticity of asbestos fibers and gangue particles for separation, but it has a big disadvantage, that is, the separation effect on short fiber asbestos is poor. . According to statistics, this part of short fiber asbestos accounts for about 40% of the total asbestos reserves.
