In that previous section, we have introduced Plackett–Burman (P–B) design and have defined four key performance indicators (KPIs). This section will discuss the results of the KPIs, summarize the results of P–B design. The results show that the material property effects are not as significant as those of the operational conditions and geometric parameters. In particular, the geometric parameters were observed to significantly influence the energy consumption, while not affecting the mixing quality and mixing time, showing their potential towards designing more sustainable mixers. Furthermore, the analysis of granular temperature revealed that the centre area between the two paddles has a high diffusivity, which can be correlated to the mixing time.

Following the above, in this part the discrete element method (DEM) and Plackett–Burman (P–B) design were used to investigate the mixing performance of a double paddle mixer. To this end, several material properties (i.e., particle size ratio, density ratio and composition), operational conditions (i.e., filling pattern, fill level and impeller rotational speed) and geometric parameters (i.e., paddle size, angle and number) were examined. In order to quantitatively analyse their effects on mixing performance, a number of key performance indicators (KPIs) were defined, namely the average steady-state RSD (KPI 1), the mixing time (KPI 2) and the average mixing power (KPI 3). In addition, KPI 4 was formulated as a multiplication of KPI 2 and KPI 3 to examine the mixing time and energy consumption at the same time.

To improve the understanding of the mixing performance of double shaft, batch-type paddle mixers, the discrete element method (DEM) in combination with a Plackett–Burman design of experiments simulation plan is used to identify factor significance on the system’s mixing performance. Effects of several factors, including three material properties (particle size, particle density and composition), three operational conditions (initial filling pattern, fill level and impeller rotational speed) and three geometric parameters (paddle size, paddle angle and paddle number), were quantitatively investigated using the relative standard deviation (RSD). Four key performance indicators (KPIs), namely the mixing quality, mixing time, average mixing power and energy required to reach a steady state, were defined to evaluate the performance of the double paddle mixer.

Material mixing refers to the homogenization of one or more materials to reduce or eliminate the uneven distribution of particle size, density, temperature and plasticity. It is a common material processing method.

The mixing of high viscosity materials is often encountered in industrial production, and the mixing efficiency and mixing effect directly affect the quality and yield of finished products. The judgment of the mixing endpoint in the mixing time determination is the key, and different researchers have different methods to judge the mixing endpoint, and its accuracy varies.

High viscosity self-cleaning mixing equipment is mainly used in the field of adhesive substances, cosmetic products, lubricants, pigments, resins, rubber and plastic auxiliary substances, emulsions, industrial dyes and other chemical products, in these areas it has played its strengths with its unique features, so that the prospects are very good. High viscosity mixer is a collection of dispersion, stirring and mixing as one of the multifunctional and efficient equipment, more and more enterprises, researchers love. So specifically how is the high viscosity mixer used in the paint industry?

Solid mixing technology is mainly used in pharmaceutical, food, pesticide, chemical and other industrial production, the application is extremely wide. In the pharmaceutical production, for the preparation of raw materials or product standardization and homogenization, the mixer is an indispensable device.

BB fertilizer is usually called blended fertilizer, which is a kind of compound fertilizer with at least two nutrients of nitrogen, phosphorus and potassium in specified amounts made by dry mixing method. In the process of BB fertilizer production, the mixing process is the key link to determine the product quality and production efficiency. As the leading equipment in the mixing process, the performance of the mixer will directly affect the product quality and production efficiency. This article briefly introduces the 12 tons per hour BB fertilizer mixing equipment.

Mixing equipment is widely used in food engineering, chemical engineering, biological engineering and other industries. They have an important impact on the process effect and product quality. Along with the gradually perfect and mature production technology, the technological parameters of mixing equipment, structure and stability, especially in the process operating conditions under the condition of same capacity only different, this kind of device is often just the difference of shape size, volume, power, size, number of assembly structure of the equipment, spare parts and types are basically the same. This provides necessary conditions for the standardization, standardization and modular design of mixing equipment. This paper briefly introduces the development of 3d parametric CAD system for mixing equipment.

Mixing of highly viscous fluids is a common unit operation in industry, and many industrial sectors encounter mixing or kneading operations of highly viscous fluids, such as rubber, petroleum, plastics, coatings, inks, and synthetic fibers, cosmetics, pharmaceuticals, food, paper and cement industries.
