What is Mixing Bucket?
In mineral flotation processing, slurry and reagent mixing uniformity directly determines the final concentrate grade and recovery rate. Traditional mixing equipment has many defects: single stirring mode leads to uneven reagent distribution; poor fluid circulation causes ore particle precipitation and tank bottom accumulation; severe vortex phenomenon reduces mixing efficiency; fixed rotating speed cannot adapt to different ore properties, resulting in unstable flotation indexes and serious resource waste.
Our Mining Mixing Bucket solves the above industry pain points with optimized full-circulation stirring structure. The upgraded spiral impeller generates three-dimensional circulating flow inside the tank to realize no-dead-angle mixing of slurry and reagents. Built-in anti-vortex baffles effectively eliminate liquid level swirling and stratification. Equipped with variable frequency speed regulation system, it can flexibly adjust stirring intensity according to ore concentration and particle size. It is the standard supporting equipment for modern gold, copper, zinc, lead and fluorite flotation beneficiation plants.

Complete Machine Configuration & Composition of Mixing Bucket
1. Radial Circulation Spiral Impeller System
Adopts large-diameter radial circulation spiral impeller design. Different from ordinary straight-blade impellers, it generates powerful axial and radial circulating fluid inside the tank. The slurry forms continuous up-and-down circulation, ensuring full contact and fusion between fine ore particles and flotation reagents. No mixing dead zones, thoroughly solving the problem of uneven reagent mixing in traditional equipment.
2. Built-In Anti-Vortex Baffle Structure
Fixed anti-vortex baffles are installed inside the tank body to effectively restrain liquid level swirling and slurry stratification during high-speed stirring. It stabilizes the internal flow field, improves mixing uniformity, and avoids ineffective vortex power consumption. The optimized fluid field design greatly enhances reagent reaction efficiency and provides stable feeding conditions for subsequent flotation operation.
3. Variable Frequency Speed Regulation Stirring System
Equipped with energy-saving variable frequency motor and stepless speed regulation device. Users can freely adjust impeller rotating speed according to slurry concentration, ore particle size and reagent type. It adapts to mixing requirements of different minerals and process parameters, realizing precise mixing control, avoiding insufficient stirring or power waste, and improving overall beneficiation flexibility.
4. Flat-Bottom Anti-Precipitation Tank Body Design
The flat-bottom streamlined tank body structure matches the circulating stirring trajectory perfectly. It effectively prevents fine ore particles from sinking and accumulating at the tank bottom, realizing long-term suspended stirring of slurry. Even for high-concentration slurry below 30% weight ratio, it can maintain uniform mixing state without material precipitation and tank blockage.
5. Fully Sealed Transmission & Anti-Dust Structure
The top-mounted drive device adopts fully sealed protective design, which effectively isolates slurry splash, dust and humid gas erosion. The optimized belt pulley and reducer transmission structure runs smoothly with low noise and low failure rate. The sealed structure protects internal bearings and transmission parts, greatly extending service life and reducing daily maintenance workload.
6. Thickened Wear-Resistant & Anti-Corrosion Tank Body
The tank body is welded with thickened high-quality steel plates, and the inner wall is treated with anti-corrosion and wear-resistant coating. It adapts to long-term erosion and friction of acidic, alkaline and high-hardness mineral slurry. The durable structure ensures stable operation in harsh mining environments, with long service life and low replacement cost.

Core Product Advantages of Mixing Bucket
1. Full Uniform Mixing, Improve Flotation Recovery Rate
Three-dimensional circulating stirring eliminates mixing dead angles, realizing full fusion of ore slurry and flotation reagents. The uniform reagent reaction environment maximizes mineral hydrophobic modification effect, effectively increasing the flotation concentrate grade and overall recovery rate by 2-5% compared with ordinary mixing equipment, bringing considerable profit growth for mines.
2. Anti-Precipitation & Anti-Vortex, Stable Operation
Flat-bottom anti-sedimentation structure + built-in anti-vortex baffles completely solve common problems such as tank bottom material accumulation, slurry stratification and liquid swirling. The slurry always maintains uniform suspension state, ensuring consistent feeding concentration for flotation machine and stable long-term beneficiation indexes.
3. Wide Adaptability & Flexible Parameter Adjustment
Variable frequency speed regulation supports free switching of low-speed uniform mixing and high-speed rapid stirring. It is suitable for various metal and non-metal ores such as gold, copper, zinc, lead, fluorite and talc. It can stably process slurry with weight concentration ≤30% and particle size ≤1mm, covering most beneficiation mixing scenarios.
4. Energy-Saving & Low Operating Cost
Optimized fluid dynamics impeller design reduces invalid power consumption. The variable frequency motor automatically adjusts power according to working conditions, saving 20%+ electric energy compared with fixed-speed mixing tanks. Simple structure with few vulnerable parts reduces daily maintenance and replacement costs.
5. Durable & Low Failure Rate
Wear-resistant and anti-corrosion tank body and fully sealed transmission structure adapt to long-term harsh mining working conditions. The top-mounted drive avoids slurry immersion damage, with stable mechanical operation and ultra-low failure rate. It supports 24-hour continuous uninterrupted production, improving beneficiation line operation efficiency.
6. Simple Installation & Easy Maintenance
Integrated modular design with compact structure and small floor space, convenient for on-site installation and layout. The open tank body and top drive structure are convenient for daily cleaning, inspection and fault maintenance. Low operation technical threshold, saving labor management cost for beneficiation plants.

Working Principle & Production Flow of Mixing Bucket
Working Principle
The Mining Mixing Bucket adopts radial circulation spiral fluid mixing principle. The motor drives the reducer and impeller to rotate at a stable speed through the belt transmission system. The high-speed rotating spiral impeller generates strong axial and radial circulating flow inside the flat-bottom tank.
The mineral slurry and flotation reagents form continuous up-and-down three-dimensional circulation, realizing full contact, stirring and fusion. The built-in anti-vortex baffles eliminate liquid level swirling and slurry stratification to ensure uniform mixing. After sufficient chemical reaction, the evenly mixed slurry overflows from the discharge port and is stably fed into the flotation machine for subsequent separation operation.
Standard Production Flow
Ground Ore Slurry Feeding → Flotation Reagent Adding → Variable Speed Circulation Stirring → Full Slurry-Reagent Fusion & Reaction → Anti-Vortex Uniform Stabilization → Qualified Slurry Overflow Discharge → Flotation Machine Feeding
