Along with the progress of society, the level of processing technology has become more mature, and the development of flotation machine also has earthshaking changes in the world. In the view of some large ore dressing equipment manufacturers, in order to conform to the development of social production and the expansion of enterprise scale, the processing of flotation machine gradually move to the automatic control production direction. The key of automatic control of the flotation machine is to realize the sequence control of flotation process and the implementation of flotation beneficiation process stability control and optimal control. Below the follow passage, the experts in our company will give you the detailed understanding of the three automatic control systems for flotation machine.
The sequence control of flotation process is mainly to achieve the stirred tank, and the electrical interlocking protection of the flotation machine. The starting up of the machine should be in accordance with the principles of stirred tank and flotation machine order to start and the normal shutdown order should be in accordance with the order of stirred tank. The flotation machine in turn delays parking to deal with the remaining material on the device. Through the implementation of automatic control of flotation process, it has achieved the security and stability of the whole process. It also lays a good foundation for the optimized balance of the flotation process, which is efficient and reliable.
During the operation of flotation machine, bubble formation in the mineralization process of the foam layer and the scraping process as well as the pulp level control process will be closely related with each other. The measure of mineralization effect and suitable foam layer thickness control is the important measure to ensure the stability and improve the flotation index.
Flotation level plays a very important role in the flotation process. Without a certain thickness of the foam layer, it will scrap out flotation high grade concentrate will be less, and the tailings grade and metal recovery rate will be low; if the foam layer is too thick, it will scrap out large amount of flotation concentrate with low grade, which will affect the concentrate grade. The liquid level control system of flotation cell signal can be read through communication, so as to achieve the control of the liquid level device built-in control system.
