Automatic control of mineral processing is the basic standard for modern intelligent mining work, and our flotation chemical processing technology should mainly carry out automatic control of drug delivery. Market research has found that solenoid valve dosing machines are the choice of many manufacturers. Do you know the reason?
The flotation reagent fully automatic drug delivery control system is a type of specific qualitative analysis that can remotely control the system and adjust. It is a timely dosing device that uses the system to control the drug delivery machine to achieve fully automatic drug delivery. It can control several drugs at the same time. The point is given to the demand. At this stage, China's flotation reagent automated control drug plus system mostly uses flow control. The control system is mainly divided into a control part and an actuator. In industrial production, PLC is used to achieve control, and there are many actuators. Use solenoid valves and dosing pumps. Because solenoid valves are relatively cheap and easy to maintain, solenoid valve control is more commonly used on site.
The solenoid valve dosing machine is based on the calibrated total flow rate of the solenoid valve opened for 1 second when the liquid level in the medicine storage tank is stable, and the frequency of opening per minute is calculated based on the calculation. The solenoid valve dosing demand range is relatively large. The range of adding demand is 0-20000m\/min, which can be adjusted at will. The greater the demand, the higher the degree. The metering pump has a small range of adding demand, and the range of adding demand is 0-350ml\/min, which can be adjusted at will. The degree is within the range of drug delivery. Stable. The solenoid valve is limited by the switching frequency. The normal service life of the solenoid valve is one million switching times. The response speed of the solenoid valve can be as short as several MS, and even the pilot solenoid valve can be controlled within tens of seconds. In MS, due to its self-contained control loop, it is more sensitive than other automatic control valves and has very good control accuracy.
The flotation reagent link uses a solenoid valve dosing machine to select and gather mineral components. The drug delivery link can simultaneously interfere with the index value of the flotation reagent. Implementing mechanical automation of the drug delivery link can solve the problem. The adverse effects caused by employees not making immediate adjustments to the changes in the flotation reagents, and the implementation of automated drug delivery control is also a necessity of social development.
