Coal gangue identification flowchart. Technical features ※ Wide processing size range: It can handle 30- 600mm raw coal. The upper limit of separation is 600mm and the lower limit is 30mm. ※ High separation accuracy: The rate of gangue …

Particle flow simulation of broken gangue backfill materials can be used to effectively study the bearing-compression characteristics of gangue backfill materials. The 3D reconstruction of the digital model for the real shape of the irregular gangue blocks is crucial for the numerical simulation of particle flow to accurately express the spatial and temporal …

However, the above studies focus on monocular image processing or 2D feature extraction, and the applied machine learning methods are difficult to implement for large-scale training samples. Different from machine learning methods, the neural network has strong robustness, memory ability, nonlinear mapping ability, and strong self-learning ability.

In the process of coal mining, the separation of coal and gangue is a very important step. Traditional coal preparation methods include manual coal preparation, heavy medium coal preparation, ray projection coal preparation, etc. these methods can not separate coal and gangue under the condition of safety and speed at the same time. Therefore, to …

Process Mineralogy. The treatment of auriferous ores presents several challenges to the metallurgists and plant operators due to there are some factors that have an important impact on the process. Without any doubt the mineralogy is the key aspect of the process performance. Basically, there are several options to be considered at the moment ...

The original and CLAHE-processed pictures of coal and gangue are shown in Fig. 1. The pictures after particle edge detection and watershed segmentation are shown in …

To address the aforementioned concerns, some researchers have tried to import image processing and pattern recognition in coal/gangue di erentiation. Yu [6] extracted grey ...

Coal gangue is residual abandoned coal, produced after the pre-processing steps of mining. It is an amalgam of several unwanted substances. It is important to separate coal gangue from lump coal before fed to thermal power plants. In this paper, investigation on the fundamental characteristics of coal images and gangue images with digital image …

The experiment results showed that the images of coal and gangue can be precisely recognized based on RS-EEM under the influence of long running pollution and …

A gangue sorting system, and a convolutional neural network model based on AlexNet, which has higher recognition rate for coal and coal gangue, and provides important reference for identification and separation of coal and gangue. We designed a gangue sorting system,and built a convolutional neural network model based on AlexNet. Data enhancement …

Coal gangue, an industrial solid waste discarded from coal mining and processing, was used as the sole raw material to prepare brick. The coal gangue was crushed, homogenized, milled and then pressed into green compacts. The dried compacts were sintered at different temperatures for 2 h. The obtained brick samples were characterized with X-ray …

Download Citation | Image Processing and Recognition System Based on DaVinci Technology for Coal and Gangue | In this paper, an image processing and recognition system of the coal and gangue has ...

High Quality Mini Stone Crusher Process Coal Gangue at . A mini stone coal gangue roller jaw crusher would include a single actuator and processing wedge gap to perform the functions …

Machine vision recognition is the most popular method for gangue separation. In 2007, David M. Hobson et al. [7] designed an image processing method based on texture feature recognition: the original image is processed by an edge detector, and then the gangues are identified by density resolution and the proportion of bright spots.

Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue mineral, is one of the main sources of acid mine drainage. Re-use. Minerals that were once thought of as gangue, and were dumped, may later find a …
