In the coatings and inks industry, achieving consistent product quality is closely tied to the efficiency of pigment grinding and dispersion. However, manufacturers often encounter numerous challenges during the grinding process. These issues, if unresolved, can lead to increased operational costs, diminished product quality, and reduced competitiveness in the market. Understanding these challenges and deploying advanced integrated solutions is essential for modern manufacturers. This article explores some of the most prevalent issues faced by industry professionals, and how integrated pigment processing solutions, like the Plusmill Evo by IEC+, are helping resolve these challenges to optimise operations and productivity.

One of the main challenges in pigment grinding is achieving a consistent and optimal particle size distribution (PSD). Poor dispersion can cause inconsistent PSD, leading to colour variation, poor film formation, and issues with stability. Advanced grinding technology that ensures better control of the PSD can prevent these issues, allowing manufacturers to achieve the desired colour and consistency in their products.
Certain pigments, such as carbon black, are notoriously difficult to grind, while others, like titanium dioxide, require effective dispersion rather than grinding. These resistant pigments present challenges due to their complex molecular structures or specific processing requirements, which can lead to inefficiencies if not handled correctly. Addressing these challenges requires sophisticated solutions capable of delivering high energy inputs and advanced dispersion techniques to achieve fine and uniform particle distribution.
Another significant issue in pigment grinding is finding the balance between under-grinding and over-grinding. Under-grinding results in insufficient dispersion, which affects the colour and stability of the pigment, while over-grinding leads to unnecessary energy consumption and possible pigment degradation. Achieving the right level of grinding is crucial for both product quality and energy efficiency.
In today’s highly competitive market, there is a growing demand for technologies that provide not only high performance but also energy efficiency. Integrating more energy-efficient grinding technology helps reduce costs while improving productivity. High-efficiency systems offer cutting-edge solutions for optimising grinding processes and reducing operational expenses.
The challenge of minimising waste while maximising yield is crucial in pigment grinding. Inefficient grinding systems often result in significant material loss, which drives up production costs. Integrating closed-loop systems with automated pigment dosing and management ensures better material utilisation, reduces waste, and increases overall yield.
The demand for innovative grinding solutions has never been higher. As the coatings and paint industries evolve, companies need to adapt by adopting new technologies that improve both speed and consistency in grinding. Modern pigment processing solutions, such as integrated systems that combine grinding, dispersion, and pigment management, represent the future of the industry.
Integrated pigment processing solutions offer a way to tackle these challenges head-on. By automating key parts of the pigment grinding and dispersion process, these systems help reduce variability, improve consistency, and minimise human error. These technologies optimise the entire workflow, from initial grinding through to final dispersion and pigment management. With features like real-time monitoring, automated adjustments, and self-calibration, these systems ensure that every batch of pigment is processed to the exact specifications required.
