The TENCAN JM-50 Chocolate Ball Mill is a high-efficiency grinding system designed for ultra-fine particle size reduction in industrial applications. It consists of a grinding chamber with internal media, a stirring mechanism, and auxiliary systems such as a material recirculation system, temperature control jacket, programmable timer, and variable speed drive.
Its compact design, energy-efficient operation, and low-noise performance make it suitable for academic research, corporate R&D, and industrial laboratories, especially for material development, coating research, and specialty powder processing.
The central drive shaft rotates at high speed, causing the grinding media to move in a chaotic, multi-directional motion. This generates strong impact, shear, and friction forces on the materials, resulting in micron-sized powders.
Grinding performance depends on the size, shape, and combination of grinding media. Generally, smaller media produce finer powders, while larger media provide coarser particles. Optimal media combinations and controlled rotation speeds ensure uniform particle size and high grinding efficiency.
The JM-50 is widely used in industries such as:
Advanced Ceramics: Zirconium silicate, alumina composites
Specialty Chemicals: Pigments, powders for coatings
Electronics & Magnetic Materials
Paper Coatings & Surface Treatments
Mineral Processing & New Material Development
Graphite Modification & Pharmaceutical Formulations
Calcium Carbonate Refining
It is ideal for ultra-fine grinding, material homogenization, and specialized powder development.
High Energy Conversion Efficiency: Reduces operating costs
Adjustable Particle Size: Control fineness via processing time and speed
Low Noise Operation: Advanced vibration reduction, <60 dB
User-Friendly Design: Simplified operation and maintenance
Flexible Operation Modes: Supports batch or continuous processing
Temperature Control Jacket: Maintains stable thermal conditions
Customizable Configurations: Optional programmable control, speed regulation, and material recirculation
Multiple Chamber Materials: 316L stainless steel, alumina ceramic, polyurethane lining, yttria-stabilized zirconia
