7. The air is microbubbles, the specific surface area is large, and the effective utilization rate of air is high.

Device application

It can be used in non-ferrous metals, ferrous metals, non-metallic minerals, and sorting for the rougher flotation process, selected scavenger job.

Equipment principle

One or several air chambers are arranged under the tank of the equipment, and the upper cover of the air chamber is evenly filled with the inflation check valve. When the pressurized air is fed, the check valve is opened, and the pressurized air enters the flotation tank and enters. The air in the tank becomes a micro-bubble in the ore liquid, and the ore particles adhere to the bubble and rise with the bubble to overflow into the overflow tank.

Second, dry permanent magnet double roll magnetic separator (strong magnetic, general magnetic)

Features

The magnetic field is strong, the suction is large, the iron removal rate is high, the maintenance-free, energy-saving, safe and reliable use, etc., can adjust the control feed amount, is suitable for different particle requirements, and has a long working life.

Device application

Dry the rare earth permanent magnetic separator is a continuous magnetic separation apparatus of the automatic removal of iron from dry feed, the internal circuit design using a unique, high performance Nd-Fe-B permanent magnet material as a king magnetic source, a strong magnetic field, a suction Large, high iron removal rate, maintenance-free, energy-saving, safe and reliable use, can be adjusted to control the amount of feed, suitable for different particle requirements.

The magnetic separator uses a permanent magnet source to sort the weak magnetic metal ore powder or to dry or wet the non-metallic mineral powder.

The magnetic separator can fully exert the magnetic peak effect of all magnetic strips, effectively improve the grade and yield of the magnetic separation product, and has a simple structure and processing capacity.

Equipment principle

When the magnetic separator is used for beneficiation , the magnetic flux roller mounted on the magnetic separator rotates continuously, and the magnetic field strips arranged in parallel in the axial direction alternately change the position of the highest magnetic line at the edge formed by the outer circumference of the magnetic cylinder. Through the time difference of rotation, it effectively compensates for the position difference of the ore dressing powder which is vertically cut off. After the scanning of the magnetic peak line published in the axial direction of the collecting magnet, all the ore powders can be subjected to each magnetic wave without missing. The rotation of the maximum magnetic lines on both sides of the strip, as long as all the low specific magnetic susceptibility powders within the range of the magnetic pole peak manager of the magnetic strip are reached, they will be adsorbed and selected.

The magnetizing roller of the present invention further performs a strong magnetic separation metallurgy by a conventional process of chemically separating ore ore by weak magnetic minerals such as copper , molybdenum , aluminum , vanadium , titanium , lead , zinc , gold, hematite and the like. Mineral enrichment, primary selection can avoid chemical modification of non-metallic ore bodies, not only significantly reduce environmental pollution, but also can significantly reduce the cost of mineral processing, reduce the consumption of energy and chemical raw materials, improve smelting capacity, The recycling of non-metallic ore bodies is more advantageous. Due to the low cost of mineral processing, a large number of sedimentary tailings that cannot be further sorted in the past can also be used as valuable resources for reuse. In the separation and purification of non-metallic minerals such as mica , quartz , kaolin , calcite , fluorite, and zircon , metal impurities can be significantly reduced. When the high-energy magnetic material is installed, the added value of the product can be doubled.

Third, no pressure feeding two products heavy medium cyclone

Features

1, simple structure, convenient operation, smashing less, less secondary sludge coal, high separation efficiency.

2. It is made of high-aluminum ceramics, high- chromium alloy, silicon carbide and other wear-resistant materials. It has good wear resistance, long life and excellent cost performance.

Device application

The coal is selected by the heavy medium cyclone, and the sorting efficiency is high, and the difficult coal can be effectively treated, and the washing granularity is wide.

The medium of the heavy medium cyclone is a high-density suspension. Under the action of centrifugal force, the minerals are mainly separated by specific gravity in the heavy medium cyclone. As a result of the separation, high-specific gravity materials (such as vermiculite) are concentrated on the outer wall and along the spiral. The downward movement of the wire is discharged through the bottom flow port, and low-density minerals (such as clean coal) cannot penetrate the heavy medium suspension bed and are concentrated in the center portion, and are discharged from the overflow port, thereby achieving efficient and accurate sorting.

Equipment principle

The separation of the ore particles in the heavy medium cyclone basically follows the "Archimedes" principle. The ore enters the cyclone under the action of centrifugal force, and the densely-contained ore rushes to the wall of the vessel. Under the action of the external spiral flow, it is discharged from the bottom, and the light-density ore enters the “separation cone” and the inner spiral flow Under the action, it is discharged from the overflow.

Fourth, XJ (XJK, A) type flotation machine

Features

1. Suitable for fine grading of dry micron products, grading of spherical, flake, and irregularly shaped particles, as well as grading of particles of different densities.

2. The granularity of the graded product can reach D97: 3 ~ 150 microns, the product granularity can be adjusted steplessly, and the variety replacement is extremely convenient.

3. Classification efficiency (extraction rate) 60% to 90%

Device application

Can be widely used in iron and other ferrous minerals, copper, gold and other non-ferrous metals and non-metallic minerals. Suitable for rough selection, sweeping and reverse flotation of small and medium flotation plants.

Product principle

When the flotation machine is working, the slurry is fed to the center of the cover plate, and the centrifugal force generated by the rotation of the impeller pulls out the slurry, and a negative pressure is formed between the impeller and the cover plate, so that the outside is automatically sucked through the intake pipe. air. The strong agitation of the impeller allows the slurry to be thoroughly mixed with the air and split into a number of fine bubbles by the gas stream. The mineralized bubbles rise to the foam layer and are scraped off by the scraper to form a foam product.
