Double impeller leaching tank
Double impeller leaching tank, also known as double impeller agitation tank, is professional stirring and leaching equipment for mineral processing plant, especially for gold cyanidation leaching circuit.Equipped with double impeller stirring structure, it provides strong and homogeneous agitation, effectively keeps ore pulp suspended without settling. It is commonly used in CIP (Carbon-in-Pulp) and CIL (Carbon-in-Leach) gold extraction production lines for cyanide leaching reaction, reagent mixing and pulp blending.This leaching agitator features stable running, low energy consumption, good sealing performance, flexible size customization according to plant capacity. It is applicable for gold ore, silver ore and other non-ferrous metal ore leaching and slurry mixing.
I. Description
The Double Impeller Leaching Tank is a mixing equipment used for gold cyanide leaching. It is suitable for gold leaching, adsorption and other mixing operations with low specific gravity, low viscosity, slow sedimentation rate, ore particle size of more than 90% at -200 mesh, and slurry concentration less than 45%. It is widely used in chemical, mineral processing, smelting and other industrial industries.
II. Application
The double-impeller leaching tank is composed of a vertical shaft, a motor base, an impeller, a coupling, a tank cover, a reducer base, a tank body, a coupling support, etc. Under the dragging and stirring action of the double impellers, the slurry flows from top to bottom in the center, diffuses through the surrounding damping plates, and air is introduced at the lower end of the shaft to mix with the slurry and circulate upward to form a uniform suspended mixed liquid.
III. Working Principle
1. Smooth ore flow: The ore slurry is mixed evenly and the power consumption is low.
2. Uniform air dispersion: The air enters the tank through the transmission hollow shaft and is evenly dispersed after being stirred by the blades, with small bubbles.
3. Low power consumption: Two new impellers are used, with large impeller diameter, low speed, low stirring power consumption, and reduced carbon wear.
4. Moderate stirring intensity: The concentration and fineness of the ore slurry in the tank are uniform, which improves the leaching rate of cyanide and the adsorption rate of activated carbon.
5. Wear-resistant material: The impeller is lined with wear-resistant rubber, with low speed and long service life.
IV. Features
The double impeller leaching tank is suitable for gold cyanide stirring leaching and carbon adsorption with a pulp fineness of more than 90% of -200 mesh and a concentration of less than 45%. It can also be used for mixed stirring leaching operations under corresponding conditions in metallurgy, chemical industry, and light industry sectors.
V.Usage and Maintenance
The use and maintenance of the double impeller leaching tank mainly includes the following aspects:
1. Regular inspection and maintenance: Regularly check the condition of the double impeller leaching tank, including whether there are obvious cracks, deformation, and looseness. These inspections help to detect potential problems in time and prevent failures.
Cleaning and maintenance: Clean and maintain the double impeller leaching tank regularly to avoid dust
2. and debris. Use appropriate detergent or solvent to clean it, then wipe it dry with a clean cloth.
3. Proper lubrication: Proper lubrication of the double impeller leaching tank can effectively reduce wear and noise and extend service life. Use appropriate lubricants and follow the manufacturer's recommendations.
4. Check and clean the keyway and mounting hole: Regularly check the inner hole and keyway of the pulley sleeve for damage. If any defects are found, replace them in time.
5. Surface anti-rust treatment: Regular anti-rust treatment can extend the service life of the double impeller leaching tank. Anti-rust oil or anti-rust paint can be used for finishing to protect the surface from oxidation or rust.
6. Avoid violent operation: During installation and maintenance, avoid violent knocking or over-tightening of bolts to prevent damage to the equipment or deformation.
7. Correct lubricant selection: Use appropriate lubricants for lubrication and avoid using incompatible or low-quality lubricants to avoid damage to the equipment.
8. Check belt tension regularly: Too little belt tension can cause slippage, while too much tension can damage the belt and related components. Therefore, it is necessary to check the belt tension regularly and adjust it as needed.
9. Avoid overloading: Avoid overloading the dual impeller leaching tank for a long time to extend its service life and reduce wear.
10. Professional maintenance: If you encounter complex or difficult problems, it is recommended to seek help from professional maintenance personnel. They have professional knowledge and skills and can solve equipment problems more effectively.
