“…We used it to screen the most important operational parameters and to optimize them. Despite saving time and resources, DoE reveals more information about the subject matter comparing to conventional One Factor At Time (OFAT), because it considers the effect of interaction between parameters ( Gilman et al, 2021 ; Hinkelmann, 2012; Laleh et al, 2017 ; Samuels et al, 2010).…”

“…It is efficient and precise especially for coarse particles, while its energy consumption is nonnegligible. Air classification and hydraulic classification can be categorized as centrifugal classification which have similar principle that utilize the difference of settling velocity in the centrifugal force field (Cepuritis et al, 2015;Silventoinen et al, 2018;Tripathy et al, 2015;Laleh et al, 2017), usually used for gas-solid separation (Gu et al, 2016), gas-liquid separation (Lazrag et al, 2016), solid-liquid separation (Silva et al, 2015), and liquid-liquid separation (Motin and Bénard, 2017). Most centrifugal classification equipment, such as dust collector cyclone and hydrocyclone (Xie et al, 2018;Hwang and Chou, 2017), belong to cyclones which have advantages of simple mechanical structure, large producing capacity, easy manipulation demand and low running costs.…”

The classification and separation of minerals happen in the traditional gravity separation simultaneously. This paper focuses on the classification performance of quartz particles in the enhanced gravity field. The classification efficiency of single quartz particles decreased then increased with the increase of rotational angular velocity, while it decreased with the increase of backwash water pressure. The classification efficiency of -0.5 +0.25mm, -0.25 +0.125mm, -0.125 +0.074mm, -0.074 +0.045mm and -0.045mm quartz was higher than the corresponding narrow size of -0.5mm quartz in general. The “fish-hook” phenomenon appeared in the partition curve of -0.5mm quartz under small/large rotational angular velocity and small backwash water pressure, and the dip point could be found in fine particles region, which indicated that the “fish-hook” was closely related with operating parameters and particle size. A medium rotational angular velocity and larger backwash water pressure could be helpful to avoid the appearance of “fish-hook” in fine particles region and achieve a better classification performance. This investigation is beneficial to understand the regularity of particle migration in the enhanced gravity field.

“…These researchers achieved a significant vertical stratification of materials, improving classification efficiency. Laleh et al [4] proposed a symmetric-nozzle classifier, where the nozzle produces powerful rotational flows. Because of this, the minerals can be sorted and classified several times, enhancing the classification accuracy.…”

Classification Performance of a Novel Hydraulic Classifier Equipped with a W-Shaped Reflector

In the present research, we propose the use of a novel hydraulic classifier equipped with a W-shaped reflector to enhance classification performance. The effects of the structural dimensions of a W-shaped reflector on the flow field of a classifier and its classification performance were investigated using numerical simulations and experiments. The results demonstrate that the reflection of the W-shaped reflector results in the return of the feed material back to the classification cavity. After this, the materials are mixed with a rising water flow in order to avoid the settlement of particles. Thus, the particles can stay longer in the classification cavity, facilitating the generation of a suspension bed and effectively improving the classification efficiency and accuracy. Our data indicates that the overall classification efficiency of the classifier embedded with the W-shaped reflector was 11.19% higher than that of a traditional classifier. Our results provide a reference for classifier optimization.
