颗粒产品生产中涉及的各种次级操作的成功取决于从先前的初级操作（例如结晶）生产具有所需尺寸和形状的颗粒。这是因为这些尺寸和形状的性质影响颗粒在二次加工中的行为。颗粒的尺寸和形状对结晶过程的条件非常敏感，因此控制这些过程是必不可少的。这种控制需要开发能够有效和高效地处理现场捕获的传感器数据的软件工具。然而，这些工具根据工艺条件和颗粒的性质具有各种优势和限制。
在这项工作中，我们采用湿磨的结晶颗粒作为一个案例研究的过程中，产生的影响典型的结晶过程。我们研究了一些我们以前介绍的工具，用于估计的粒径分布（PSD）和纵横比的弦长分布（CLD）和成像数据的优势和局限性。我们发现CLD工具比成像工具工作得更好，反之亦然。然而，一般来说，这两种工具相互补充，因此可以在合适的多目标优化方法中使用，以估计PSD和纵横比。
The success of the various secondary operations involved in the production of particulate products depends on the production of particles with a desired size and shape from a previous primary operation such as crystallisation. This is because these properties of size and shape affect the behaviour of the particles in the secondary processes. The size and the shape of the particles are very sensitive to the conditions of the crystallisation processes, and so control of these processes is essential. This control requires the development of software tools that can effectively and efficiently process the sensor data captured in situ. However, these tools have various strengths and limitations depending on the process conditions and the nature of the particles.
In this work, we employ wet milling of crystalline particles as a case study of a process which produces effects typical to crystallisation processes. We study some of the strengths and limitations of our previously introduced tools for estimating the particle size distribution (PSD) and the aspect ratio from chord length distribution (CLD) and imaging data. We find situations where the CLD tool works better than the imaging tool and vice versa. However, in general both tools complement each other, and can therefore be employed in a suitable multi-objective optimisation approach to estimate PSD and aspect ratio.
