Handling various powders and liquid additives requires specialized approaches to dosing, conveying, and recipe management. Recently Mconvey provided a complete powder dosing and mixing system for a European customer whom manufacturing modified compound granules, System scope covered from feeding, dosing, mixing, conveying, and silos.
The system has completed commissioning and acceptance and is now in normal operation. Impressed by the equipment performance and our team’s service, the customer also sent Mconvey a letter of appreciation.
Customized Solutions for Different Process Requirements
Customer’s extrusion line uses resin powder, fillers, and various functional additives, with strict requirements for dosing accuracy and batch traceability. Mconvey provided different dosing and conveying solutions based on material characteristics.
1. Screw Dosing + Pneumatic Conveying
Process Flow: Screw feeder → dosing scale → liquid dosing → Compound mixer→ pneumatic conveying to finished silos.
- Supports weighing and batching for 4 recipe components, with automatic suction and dosing for resin powder and fillers.
- Integrated with automatic oil injection and heat-mix dust collection.
- Material passes through a 1.2m³ cooling mixer buffer silo, then is pneumatically conveyed to two storage silos.
2. Dense-Phase Pneumatic Conveying System
Process Flow: Silo → dosing scale → dense-phase vessel → pressure conveying to finished silos.
- High-precision load cells provide closed-loop control over each batch’s discharge and conveying weight, ensuring full quantifiability and traceability.
Core Technical Highlight
Integrated Dense-Phase Vessel Design:
- Dual Functionality: The dense-phase pressure vessel serves as both a power source and a high-precision dosing unit, significantly simplifying the system architecture.
- Batch-Mode Precision: Operating in batch mode, the system automatically controls material feed based on preset weights to ensure high batch-to-batch accuracy.
- Enhanced Cleanliness: By eliminating intermediate transfer steps, this design minimizes material loss and contamination risks while enhancing production cleanliness and consistency.
Key Equipment
1. Compound mixer
- For materials with significant density differences, high friction coefficients, and demanding uniformity requirements, Mconvey offeredcompund Bearing assemblies handle large axial and radial loads, dual dust seals prevent powder ingress.
- Custom S6 high-torque permanent magnet motor delivers 10%-20% energy savings.
- Special wear-resistant blades extend service life by 3x, with overall capacity increased by 50%, suitable for high-intensity continuous mixing.
2. Intelligent liquid dosing machine
- Designed for formulations with multiple liquid additives.
- Diaphragm pump and intermediate tank provide stable flow, compatible with various process liquids.
- High-precision sensors with pneumatic controls ensure accurate batching. Aluminum-frame structure has a small footprint and supports online/offline switching between multiple liquids, simplifying changeover operations.
3. Centralized SCADA Automation System
- Provides real-time monitoring and centralized control for the entire powder dosing and mixing system, managing data acquisition, parameter configuration, and alarm safety handling.
- Simplifies operation and maintenance.
Overall System Benefits
The system uses high-precision sensors and automatic batching controls to minimize human error. Automated material conveying and mixing reduce manual labor. Closed conveying combined with dust collection improves workshop environment.
From dosing and mixing to conveying, Mconvey designed each step based on the client’s actual process and material properties—ensuring smoother material flow and simpler production management.
