The shallow groove separator was originally mainly used for the lump coal gangue of large-scale thermal coal preparation plants, and can also be used for the underground gangue discharge of coal mines.
In recent years, shallow groove separators have also been used in non-coal fields such as tailing and garbage sorting of non-metallic ores. This article will introduce the shallow groove separator used in coal preparation plant as an example.
Foreign brands
Heavy medium shallow groove separator began to be used as early as the 40s of the 20th century, from the DSM type sorter, McNally Trump sorter, Bavoi sorter, Liba sorter, to the later application of the more mature Daniel sorter, Peters sorter.
Before the 21st century, the shallow groove heavy medium shallow groove separator used in China was mainly imported. In 1988, Pingshuo Antaibao Coal Preparation Plant introduced Daniel heavy medium shallow trough separator from the United States, which is used to separate 150 13mm lump coal, with a processing capacity of 1500x104t a.
In the past ten years, foreign brand equipment such as Daniel separator and Peters separator have been unable to adapt to the rapid development of China's mining industry in terms of after-sales service and supply cycle, and have been unable to meet the actual needs of end users, and have slowly faded out of the Chinese market.
Chinese brand
Since the beginning of the 21st century, with the imitation and research and development of foreign equipment by Chinese equipment manufacturers, as well as the research and practical application of new coal preparation technology and the adaptability of complex minerals, the comprehensive performance of some brands of equipment has been able to fully compete with international brands, or even do better. At present, the brand factories that have done well are Zhuzhou Tianqiao Shunchen Coal Preparation Machinery Co., Ltd. and Shenyang Kedi Tongda Engineering Technology, among which the XZQ-1679 heavy medium shallow groove separator selected by Xinjiang Yili No. 4 Mine is the largest shallow trough separator in China so far.
The technology of shallow groove separator has been relatively mature, with the change of mineral occurrence, it is hoped that the domestic brand factory can do better in the wear-resistant materials of the equipment, the adaptability to different minerals and the intelligent direction, and participate more in the competition in the international market.
