[Editor's Note] The “Chasing Dreams 2019” touring research initiative for the powder industry, organized by China Powder Network, has now been successfully launched. In January, Kong Deyu, Manager of the Exhibition Department at China Powder Network, along with other team members, visited several well-known domestic pharmaceutical companies, including Lunan Pharmaceutical and North China Pharmaceutical. At the end of February, Song Chunxin, General Manager of the Fenxiangtong Division at China Powder Network, Sales Engineer Tang Wenjing, and a reporter from China Powder Network—a total of four people—visited several renowned manufacturers of mineral color-sorting equipment in Hefei. In the near future, we will gradually publish exclusive interviews with these companies, providing more mining enterprises with a deeper understanding of the mineral color-sorting equipment industry.

Interviewee: Sang Haibo, General Manager of Hefei Guxin Electronic Technology Co., Ltd. (hereinafter referred to as “Mr. Sang”)

Interviewer: Powder Network Reporter

Date: February 25, 2019

Sang Haibo, General Manager of Hefei Guxin Electronic Technology Co., Ltd.

Reporter: Could you please provide a brief overview of ore color sorting machines? How does ore color sorting technology differ from other sorting methods?

Mr. Sang: A mineral color sorter is a high-tech, mechatronic device that leverages differences in the optical properties of minerals and employs photoelectric detection technology to automatically sort out particles of different colors from a stream of mineral grains. Compared with other sorting technologies, mineral color sorters offer unparalleled advantages. Color sorting machines offer high sorting accuracy, large throughput, and low overall operating costs, making them an indispensable piece of equipment for improving ore quality in the mining industry today.
