The challenge: 30 tons of decorative paint per hour
The project’s objective was clear and ambitious: to design and install an automated line capable of manufacturing and packaging 30,000 kg of white decorative paint (water-based) per hour, with maximum reliability and precision. This was the third consecutive project that O+B carried out for Nippon Paint in China, following two similar installations in Xianning (Hubei) and Zhengzhou (Henan). This continuity reflects the client’s confidence in our ability to deliver high-performance turnkey industrial solutions
O+B’s technical solution: Comprehensive process automation
The project was developed based on a modular, highly automated solution that encompasses everything from raw material handling to final product packagingEach stage of the process was designed to maximize performance and ensure complete traceability
1. Raw material storage eight 300 m³ silos were installed to store powdered raw materials such as calcium carbonate, kaolin, talc, and titanium dioxide
2. Automatic transport and dosing of solids
A pneumatic transport system with a capacity of between 15 and 30 tons per hour feeds two waiting hoppers. Each hopper is dedicated to a group of raw materials: one for carbonate, kaolin, and talc, and another exclusively for TiO?, allowing for separate and precise management.
3. Automatic liquid dosing
The automated system manages the dosing of 18 emulsions and 40 liquid additives, ensuring precision, repeatability, and reduction of human errors.
4. Solid dispersion and mill base manufacturing
The critical mixing stage is carried out with a POLIMIX DPS-15000-OR coaxial disperser, capable of simultaneously incorporating solids from both hoppers. Its dispersion capacity of up to 50 tons per hour ensures very short cycle times and perfect product homogeneity.
5. Discharge and final homogenization
The mill base is discharged by gravity into two TA-22000 finishing tanks, designed to receive large volumes with continuous agitation, ensuring uniform mixing before packaging.
6. Performance validation
The analysis of the actual weight in the DPS-15000-OR and the two solid hoppers throughout a workday demonstrates that the system is capable of producing 30,000 kg of paint in less than 60 minutes, thus meeting the set objective.
7. High-speed automatic packaging
The finished paint is packaged using two automatic FLASH-25-TX lines, each equipped with PAILMANAGER-VX systems for feeding and handling 18-liter containers. This system allows a packaging rate of 14 containers per minute per line, with quick format change and minimal manual intervention.
