Description
The ZONESUN ZS-BM150 is an industrial vertical chocolate ball mill refiner designed for fine grinding and refining of chocolate paste, cocoa liquor, nut pastes, and other fat-based masses. Using high-strength steel balls and continuous rotational friction, it achieves a fineness of 18–25 µm.
Built with food-grade SS304 stainless steel, intelligent PLC control, and a separate structural design for easy cleaning, the ZS-BM150 is available in four capacity configurations from 150L to 1000L to match small artisan chocolate workshops through to large-scale industrial confectionery production lines.

Key Features
- Vertical Grinding Cylinder — Houses premium steel ball media and mixing shafts to finely grind chocolate paste through rotational friction and impact, achieving 18–25 µm particle size.
- Intelligent PLC Touchscreen Control — Precise control of grinding time, temperature, and parameters for consistent and reproducible results.
- Separate Structural Design — Motor and cylinder are independently designed for easy cleaning, maintenance, and rapid changeover.
- Food Safety Guarantee System — Magnetic filter removes metal scraps; the process reduces heavy metals, off-flavors, and moisture for safe, high-quality output.
- Food-Grade 304 Stainless Steel — All product-contact parts meet strict food safety standards and simplify cleaning and sanitation.
Benefits
- High Fineness — Achieves 18–25 µm particle size for exceptionally smooth chocolate texture.
- Efficient Processing — Significantly shorter grinding time compared to traditional five-roll refiners.
- Hygienic & Safe — Full food-grade stainless steel construction with easy-clean separate design.
- Temperature Control — Jacketed cylinder system maintains optimal processing temperature throughout the refining cycle.
- Flexible Capacity — Multiple models from 150L to 1000L to suit pilot-scale and full production requirements.





Why Choose the ZS-BM150?
✅ 18–25 µm Ultra-Fine Grinding Fineness: High-strength 12mm steel balls deliver consistent particle size reduction to 18–25 µm — achieving the smooth, velvety mouthfeel required for premium chocolate, couverture, and confectionery products
✅ 4 Capacity Configurations (150L–1000L): Choose from ZS-BM150, ZS-BM300, ZS-BM500, or ZS-BM1000 to match your production scale — from artisan chocolate workshops to large-scale industrial confectionery manufacturing lines
✅ Intelligent PLC Control System: Automated PLC control manages grinding time, temperature, and motor speed with precision — ensuring repeatable batch quality and reducing operator dependency in continuous production
✅ Electric Heating System: Integrated electric heating (6–12 kW depending on model) maintains optimal chocolate mass temperature throughout the grinding cycle, preventing solidification and ensuring consistent flow and refining efficiency
✅ Separate Structure for Easy Cleaning: Modular separate structural design allows quick disassembly of the grinding chamber for thorough cleaning and product changeover — reducing downtime between batches and meeting food hygiene standards
✅ Food-Grade SS304 Stainless Steel: All product-contact surfaces are constructed from SS304 stainless steel for food safety compliance, corrosion resistance, and long-term durability in chocolate and confectionery production environments
✅ Continuous Rotational Friction Refining: Vertical ball mill design enables continuous grinding action with uniform steel ball distribution, delivering consistent fineness across the entire batch volume without hot spots or uneven refining
Ideal Applications
Chocolate Manufacturing: Dark, milk, and white chocolate mass refining for couverture production, chocolate bar manufacturing, and premium chocolate ingredient supply to confectionery factories
Cocoa Processing: Cocoa liquor and cocoa paste refining for cocoa butter extraction, cocoa powder production, and chocolate mass preparation in cocoa processing facilities
Nut Paste Refining: Ultra-fine grinding of peanut butter, almond paste, hazelnut paste, and other nut-based masses requiring smooth texture and consistent particle size for premium food products
Compound Chocolate & Coatings: Compound chocolate, carob coating, and fat-based confectionery coating mass refining for biscuit, wafer, ice cream, and bakery coating applications
Specialty Fat-Based Masses: Praline paste, gianduja, marzipan base, and other specialty fat-based confectionery masses requiring precise micron-level particle size reduction for premium texture
