Read More2016-10-1 This paper presents an indirect method for determining the local gas holdup in the collection zone of flotation machines. The method includes a linear model to describe the gas holdup as a function of the superficial gas velocity and the percent area, defined as the 2D area fraction occupied by bubbles in binary images.
Read More2019-12-4 In order to address the difficulty of accurate segmentation of froth images of different sizes, a method of froth image segmentation based on highlight correction and parameter adaptation is proposed. First, a machine vision system on a single-cell flotation machine is built to collect froth images. Homomorphic filtering is used to improve the uneven brightness and shadow of the images. Fuzzy ...
Read MoreA machine vision system was installed on an industrial coal flotation column. • A convolutional neural network (CNN) was developed to extract the froth features. • A CNN-based classifier was applied to classify the froth images. • Proposed classifier yielded much
Read More2020-8-1 Abstract In recent years, the use of machine vision systems for monitoring and control of the flotation plants has significantly increased. The classification of froth images is a critical step in development of an on-line machine vision based control ...
Read MoreGet in touch with an expert. FLSmidth supplies two types of flotation machines: WEMCO and nextSTEP, the WEMCO machine is self-aerating whereas the nextSTEP machine is externally aerated. The principles of operation for self-aerated and forced-air
Read MoreThe imagers are networked through Metso Outotec FrothSense Connection Cabinets to the FrothSense Analysis Server, which runs the necessary machine vision algorithms and acts as an interface to the plant automation network using OPC. In order to fully utilize the real-time froth analyses, the system is accompanied by ACT, our advanced process ...
Read More2020-9-20 In addition, shallow machine learning models treat data as cross-sectional, failing to consider the auto-correlation and temporality among data. However, care should be taken that in a dynamic flotation process, the existence of lag time always demonstrates time-correlations between manipulating variables and processed grade/recovery.
Read More2019-10-14 Effective fault detection techniques can help flotation plant reduce reagents consumption, increase mineral recovery, and reduce labor intensity. Traditional, online fault detection methods during flotation processes have concentrated on extracting a specific froth feature for segmentation, like color, shape, size and texture, always leading to undesirable accuracy and efficiency since the ...

Read MoreSystem architecture introduction. Figure 1 shows the process flow of coal flotation and the architecture of proposed froth image recognition system. The production equipment of the flotation system is a mechanical stirring self-suction-type flotation machine with model XJX-20, where the four rooms are connected, the coal slurry and reagent are pumped into the slurry pre-processor and ...
