JKL HDR-60 Homogenizer with Rotary Sample Divider (60 L)
Integrated modular system combining batch drum homogenization and final volumetric reduction through a DRC-4 carousel rotary sample divider, ensuring complete blending and statistically representative reduction prior to analysis.
Main Applications: Sample preparation for metallurgical accounting, plant-to-laboratory reconciliation, concentrate and tailings control, and final reduction stages in automated sampling systems.
The JKL HDR-60 (M60DRC-4) is a modular homogenization and volumetric sample reduction system engineered for the complete mixing of primary sample increments and subsequent representative final reduction through a rotary carousel-type sample divider.
The unit integrates, within a single structural assembly:
Batch-type rotary drum homogenizer
Internal washing system
Reinforced structural support frame
Carousel-type rotary sample divider (DRC-4)
Controlled discharge system
Power and control panel
BATCH-TYPE DRUM HOMOGENIZER – 60 L
Technical Specifications:
Nominal working capacity: 60 liters
Configuration: Horizontal batch rotary drum
Mixing mechanism: Controlled tumbling action
Drive system: High-efficiency gear motor assembly
Support: External pillow block bearings
Directed bottom discharge system
Integrated internal washing system
Construction: Structural carbon steel and/or stainless steel per project specification
Operating Principle
The rotary drum performs a three-dimensional mixing action consisting of:
Tumbling motion
Controlled rotational movement
Continuous particle reorientation
Complete volumetric recombination
This allows:
Homogeneous mixing without excessive shear stresses
Elimination of density or particle size segregation
Low energy consumption
Preservation of particle size integrity
Function within the Sampling System
The drum ensures complete blending of all primary increments, providing:
Statistical representativity prior to reduction
Full homogenization of the composite lot
Minimization of Fundamental Sampling Error (FSE)
CAROUSEL-TYPE ROTARY SAMPLE DIVIDER (DRC-4)
Technical Specifications
Type: Rotary carousel divider
Configuration: 4 sample receivers (DRC-4)
Adjustable reduction ratio: 12.5% to 50%
Direct feed from homogenizer discharge
Continuous and equidistant distribution
Integrated rigid structural base
Operating Principle
The rotary divider performs volumetric reduction based on:
Full cross-sectional cutting of the material stream
Uniform angular distribution
Time- and volume-proportional division
This guarantees that the reduced sample retains:
Identical particle size distribution
Identical mineralogical composition
Identical metal grade proportion of the homogenized lot

KEY TECHNICAL ADVANTAGES
True Pre-Reduction Homogenization
Prevents reduction of non-homogenized material — a frequent deficiency in conventional sampling systems.
Representative Reduction in accordance with ISO 13909 best practices
The rotary cutting action eliminates bias caused by irregular material flow.
Segregation Elimination
Direct drum-to-divider discharge prevents stratification.
Statistical Error Control
Reduces:
Fundamental Sampling Error (FSE)
Grouping and Segregation Error (GSE)
Delimitation Error
Suitable for:
Final concentrate
Tailings
Flotation feed
Third-party purchased ores
APPLICATION IN METALLURGICAL ACCOUNTING
The JKL HDR-60 ensures:
Solid statistical basis for plant-to-laboratory reconciliation
Reduction of systematic bias
Increased reliability in mineral settlement and commercial transactions
Full traceability of the reduction process
OPTIONAL CONFIGURATIONS
Drum in AISI 304 / 316 stainless steel
Anti-abrasion lining
Automatic CIP washing system
Variable Frequency Drive (VFD)
Integration into plant PLC systems
Safety interlocks
TECHNICAL CONCLUSION
The JKL HDR-60 (M60DRC-4) provides a fully integrated homogenization and final volumetric reduction solution designed for operations where sampling representativity and metallurgical accounting accuracy are critical.
