Ore dressing automation technology is the basic requirement for modern intelligent mining area work, and our flotation reagent process should first realize dosing automation technology. Market research found that solenoid valve dosing machines are the choice of many manufacturers. Do you know the reason?
The automatic control system for fully automatic dosing of flotation reagents is a type of accurate quantitative analysis and on-time dosing equipment that can be automatically controlled and adjusted over a long distance. It uses the system to control the dosing machine to achieve fully automatic dosing, and can control the dosage of several drug points at the same time. .At present, China's flotation reagent automation technology and drug addition systems mostly use flow control methods. The automatic control system is mainly divided into a control part and an actuator. In industrial production, PLC is used to achieve control. The actuators mostly use solenoid valves and processing units. For medicine pumps, due to the low price of solenoid valves and easy maintenance, solenoid valve control is mostly used on site.
The solenoid valve dosing machine estimates the frequency of opening per minute based on the calibrated flow rate of the solenoid valve when it is opened for 1 second when the liquid level in the medicine storage tank is constant. The solenoid valve has a relatively large dosing range. The range is 0-20000m\/min, which can be adjusted at will. The larger the dosage, the higher the degree. The metering pump has a small dosage range, and the dosage range is 0-350ml\/min, which can be adjusted at will. The degree is constant within the dosage range. The solenoid valve is controlled by the switching frequency. The normal service life of the solenoid valve is one million switching times. The response time of the solenoid valve can be as short as a few ms, and even the pilot solenoid valve can be controlled within tens of ms. Because it has a self-contained control loop, it is Compared with other automatic control valves, they are more flexible and have very good control and use accuracy.
The flotation reagent link is the selection and aggregation link of mineral components using a solenoid valve dosing machine. The quality of the dosing link can directly interfere with the index value of the flotation reagent. Implementing mechanical automation of the dosing link can eliminate the need for employees to immediately monitor the flotation reagent. The adverse effects caused by the relative adjustment of changes in the pharmaceutical selection process, and the completion of pharmaceutical dosing automation technology are also inevitable for social and economic development.
