QMJ Series Chocolate Ball Mill Machine Manufacturers
As a QMJ Series Chocolate Ball Mill Machine Manufacturers , we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
As a direct QMJ series chocolate ball mill manufacturer based in Suzhou, China, Golden Eagle Machinery & Equipment Co., Ltd. designs and builds vertical ball mills for the confectionery and food processing industries. Our QMJ series covers both continuous and batch-type machines, engineered to refine chocolate masses, compounds, spreads, creams, cocoa masses, nut pastes, and other fat-based products to a consistent fineness between 18 and 25 microns.
With nearly 30 years of experience in chocolate equipment production, we supply machines that integrate easily into existing lines or new turnkey projects. Our ball mills are used by small-batch producers, mid-size confectionery plants, and large-scale manufacturers worldwide, including markets in Europe, the Middle East, Southeast Asia, and the Americas.

Application Fit: Where QMJ Ball Mills Deliver Value
Our ball mills are engineered for the final refining stage in chocolate production, typically after pre-refining in a Chocolate Conche. The continuous QMJ model is the preferred solution for fine-grinding various masses like compounds, spreads, creams for fillings and coatings, cocoa masses, nut pastes, and other fat-based masses. Its unique grinding chamber delivers one-step grinding at low temperatures, ensuring consistent quality regardless of operator skill or raw material fluctuations.
The batch QMJ-1 is used for quickly milling filling material, making it suitable for production lines that require frequent product changes or smaller output. It is also effective for grinding liquid oils such as jam and peanut butter, expanding its use beyond chocolate.
Key Technical Features and Benefits
- Efficient grinding: High-speed rotation of the ball medium achieves uniform refinement to 20–25 μm average fineness.
- Intelligent control: PLC full-auto control on continuous models regulates power, temperature, and throughput.
- Temperature management: Inside and outside cooling systems maintain low grinding temperatures, preserving flavor and texture.
- Degassing and deodorization: Exhaust fan removes unwanted gases and odors, improving taste and color.
- Emulsification: Agitator ensures thorough mixing with lecithin and other emulsifiers for stable product quality.
- Hygienic design: Food-grade stainless steel construction meets food processing standards.
- Energy saving: Inverter motors and efficient cooling reduce energy consumption and component wear.
Configuration and Integration
We configure each QMJ ball mill to match your line layout and production targets. Standard options include:
- Capacity variants: 500L, 1000L, 1500L for continuous; 300 and 500 for batch.
- PLC control with touchscreen interface for automated operation.
- Magnetic filter to remove metal particles.
- Level sensor for auto-discharging in continuous mode.
- Self-circulation chocolate pump with magnetic filter (batch model).
- External centralized heating and cooling system connection points (batch model).
Our engineering team can adapt the machine to your existing upstream and downstream equipment, such as Chocolate Holding Tank and Chocolate Tempering Machine. We also offer customizations based on your drawings or samples.
Quality Assurance and Compliance
We hold ISO9001-2000 quality certification and CE certification for the European Union. Our manufacturing processes include inspection at each stage, and finished machines undergo final testing before leaving the factory. We provide inspection certificates and can arrange third-party testing such as SGS upon request. All machines are designed to meet international food safety and electrical standards.
Installation, Maintenance, and Support
We provide comprehensive support to ensure smooth commissioning and long-term reliability:
- Installation supervision and operator training by our experienced engineers.
- Detailed documentation including operation manuals, wiring diagrams, and spare parts lists.
- Spare parts availability for critical components such as pumps, motors, and sensors.
- Preventive maintenance guidance to maximize uptime.
Our proximity to Shanghai port facilitates efficient sea freight delivery, and we can arrange air freight for urgent orders.
Information We Use to Configure Your Solution
To prepare an accurate proposal and configuration, we need the following project details:
- Product type (chocolate, compound, filling, nut paste, etc.) and recipe characteristics.
- Required production capacity (kg/h or kg/batch).
- Target fineness (micron) and acceptable particle size distribution.
- Operating temperature range and cooling water availability.
- Available floor space and layout constraints.
- Electrical supply specifications (voltage, frequency, phase).
- Integration with existing equipment (conche, holding tank, tempering machine).
- Automation level required (manual, semi-auto, PLC).
- Any specific hygiene or safety certifications needed for your market.
With this information, we can recommend the right model, configure auxiliary systems, and provide a detailed quotation.
Frequently Asked Questions
What is the difference between the QMJ batch and continuous ball mill?
The QMJ continuous ball mill is designed for high-volume production, processing 500–1500 kg/h with a fineness of 18–22 microns. The QMJ-1 batch ball mill is suited for smaller batches up to 400 kg per cycle, ideal for filling materials and quick product changes. Choose continuous for steady output, batch for flexibility.
Can the QMJ ball mill handle materials other than chocolate?
Yes, the QMJ series is versatile and can grind various fat-based masses such as compounds, spreads, creams, cocoa masses, nut pastes, and even liquid oils like jam and peanut butter. The vertical design and adjustable speed allow adaptation to different viscosities.
What cooling systems are available?
Our ball mills feature inside and outside cooling systems to control grinding temperature. The batch model connects to an external centralized heating/cooling system (not included) for precise temperature management. Continuous models have integrated cooling to maintain low temperatures during operation.
How do you ensure product quality and safety?
We use food-grade stainless steel for all contact parts, include magnetic filters to remove metal contaminants, and design the system to prevent contamination. Our factory is ISO9001 certified, and machines carry CE certification. Each unit is tested before shipment, and we can provide inspection certificates.
What after-sales support do you offer?
We provide installation guidance, operator training, and technical documentation. Our engineers are available for on-site commissioning if required. We also supply spare parts and offer remote troubleshooting to minimize downtime.
