Mixer Overview

The mining agitator, also called mixer,  is a kind of agitating equipment used for ore pulp agitation before flotation operation, so that ore pulp and reagent are fully mixed. It can also be used for stirring other non-metallic minerals. Mixing barrels are very common in metal and non-metal beneficiation, such as flotation beneficiation, hydrometallurgy, rare and precious metal leaching and extraction, and are also used in many sewage treatment and production of some chemical raw materials.

What are Benefits of Using Mining Agitator Tanks Mixer?

Focusing specifically on the Mining Agitator Tank, why is it indispensable for mineral processing plants?

• 1. Prevent Sedimentation: In mining, you grind rock into powder and mix it with water. If this mixture stops moving, the rock powder settles to the bottom like cement. Once it hardens, you have to dig it out by hand. The agitator runs continuously to ensure the slurry remains fluid.
• 2. Uniform Chemical Reaction: In gold leaching (CIL/CIP processes) or flotation, chemical reagents must touch every single particle of ore. The impeller circulates the chemicals evenly throughout the tank. Without this agitation, chemicals would float to the top, and gold would be lost in the tailings.
• 3. Energy Efficiency for Liquids: Agitators use the fluid’s own dynamics to mix. Once the vortex is established, keeping it going requires relatively low power compared to the brute force needed for concrete mixers.

What are Mining Agitator Tanks Mixer Used For?

While the Concrete Mixer is the heart of a block-making factory, the Agitator Tank is the lung of a beneficiation plant.

Agitator Tank Applications:

• Slurry Preparation: Installed before a flotation machine to mix conditioning agents with the pulp.
• Leaching Tanks: Huge tanks used in gold cyanidation where activated carbon is mixed with ore slurry for 24+ hours.
• Storage Buffers: Keeping slurry moving while waiting for the next process stage (e.g., before a filter press).
• Chemical Industry: Mixing acids, polymers, or sewage treatment sludge.

Mixer applicable materials

 copper ore, gold ore, lead-zinc ore, fluorite ore, coal, ore, coal mine, bauxite ore, iron ore, talc, etc.

Structure of Mixer

What are Key Components of the Mining Agitator Tanks Mixer?

The simplicity of the Mining Agitator contributes to its reliability.

• 1. The Impeller (propoller):This is the most critical part. ZONEDING uses rubber-lined or urethane impellers. The shape is designed to push liquid down towards the bottom, where settling happens, forcing it back up the sides.
• 2. The Shaft:A long vertical steel pole connecting the motor to the impeller. It must be perfectly balanced to avoid wobbling.
• 3. The Guide Tube (Draft Tube):Often found in high-efficiency tanks. It is a cylinder in the center of the tank. It forces the liquid to circulate in a specific “W” shape pattern, dramatically increasing mixing efficiency without increasing motor power.
• 4. The Tank Body:Rolled steel plate. ZONEDING ensures these are anti-corrosion treated, especially if you are using acidic leaching chemicals.

How Does the Mining Agitator Tanks Mixer Work?

Understanding the physics helps you operate it better.

• The Mechanical Process:The motor drives the V-belt, which spins the impeller. The impeller spins at a relatively high speed.Because the impeller is located near the bottom of the tank, it creates a negative pressure zone.Slurry is sucked down into the impeller and then thrown outward radially against the tank walls.The slurry hits the wall, travels up, and then spirals back down to the center.
• The Result:This constant cycle creates a “suspension state.” The Mineral particles are fighting gravity. Gravity pulls them down; the impeller pushes them up. When these forces balance, you have a perfect homogenous mixture ready for the flotation cell.

Working Principle of Mixer

Advantages of Mixer

There is less ash left. Besides, there is a watershed set on the bottom. So the whole machine is very clean.

Advanced equipment performance. The quality of production is stable. The mixing is even. And the discharging is quick.

The performance characteristics of mixer

• Compact structure and reliably sealing. Besides, there is an ash damper installed at the mouth of the discharging gate, which can prevent water and flog to enter in.
• It has advantages of evenly mixing, sector shape of propeller and large contacting proportion.
• There are many rows of nozzles, which can guarantee water to flow evenly.

What is the Price of A Mining Agitator Tanks Mixer?

Price varies wildly based on size and lining material.

Agitator Tank Pricing Factors:

• Tank Volume: Ranges from a small 1m³ tank ($2,000 USD) to a massive 4m diameter leaching tank ($15,000+ USD).
• Lining: A tank used for standard water/sand mixing is cheap. A tank used for Acid Leaching requires rubber lining or stainless steel, which can double the price.
• Impeller Type: Standard steel impellers are cheap. Composite wear-resistant impellers cost more.

How to Select the Suitable Mining Agitator Tanks Mixer?

Do not just guess the size.

• 1. Calculate Retention Time:If you need a chemical reaction to last 15 minutes, and your flow rate is 10 tons/hour, you calculate the required tank volume based on that flow.
• 2. Particle Density:Heavier ore (like gold or iron) settles faster. You need a higher power motor and a more aggressive impeller pitch compared to lighter materials like coal or graphite.
• 3. Liquid vs. Paste:
  • If the material flows like water = Mining Agitator.
  • If the material piles up like wet sand = Industrial Twin Shaft Mixer.
• 4. Corrosiveness:If you are using Cyanide or Acid, you must tell ZONEDING engineers so we can rubber-line the tank and impeller. Standard steel will dissolve in weeks.

How to Install and Operate the Mining Agitator Tanks Mixer?

Installation is straightforward but precision is required.

• Installation:
  • Vertical Alignment: The tank must be perfectly vertical. If it tilts, the slurry level will be uneven, and the shaft will experience stress, wearing out the bearings prematurely.
  • Elevation: Usually, these tanks are installed on platforms so they can feed the next machine by gravity. Ensure the steel structure can support the weight of the tank plus the full load of slurry.
• Operation:
  • Start-Up: ideally, start the agitator when the tank is empty or has water. Starting a motor when the impeller is buried in settled sand (sediment) is the #1 cause of motor burnout.
  • Shutdown: If you stop the agitator, you usually need to drain the tank. If you leave the slurry inside and turn it off, the solids settle. You will not be able to restart it later without digging it out.

What are Maintenance Tips of Agitator Tanks Mixer?

Because they run 24/7, maintenance is about prevention.

• 1. V-Belt Tension:The belts stretch over time. Loose belts mean the impeller spins slower. Slower spin = Sedimentation. Check belt tension weekly.
• 2. Impeller Wear:The impeller is constantly sandblasted by the slurry. It will wear down, become smaller, and lose efficiency. Inspect it every 3 months. If it loses 15% of its diameter, replace it.
• 3. Motor Bearings:Listen for grinding noises. ZONEDING designs allow for easy greasing points.
