However, due to the backwardness of traditional machines in the current mineral processing plants, the work efficiency of this link is low. At the same time, relying solely on the experience of workers, it is inevitable that many errors caused by manual work will occur, which will affect the development of subsequent work links. For most mineral processing plants, it is impossible to realize the automated and intelligent liquid level measurement process by relying on existing equipment and devices, and the various problems encountered in this process will bring significant losses to the factory in terms of manpower, financial resources and other aspects. Therefore, a flotation machine liquid level automatic control device based on laser measurement is designed to save human resources while improving the work efficiency of subsequent work links, and through this system, the mechanical automation of some operations of the mineral processing plant is realized, which has broad market prospects and industrial application value, and also provides practical experience for the subsequent creation of automated factories.
